results.assistant.model.tools.variableExtractionPlan

object

This is the plan to extract variables from the tool's response. These will be accessible during the call and stored in call.artifact.variableValues after the call.

Usage:

Use aliases to extract variables from the tool's response body. (Most common case)

{
  "aliases": [
    {
      "key": "customerName",
      "value": "{{customer.name}}"
    },
    {
      "key": "customerAge",
      "value": "{{customer.age}}"
    }
  ]
}

The tool response body is made available to the liquid template.

Use aliases to extract variables from the tool's response body if the response is an array.

{
  "aliases": [
    {
      "key": "customerName",
      "value": "{{$[0].name}}"
    },
    {
      "key": "customerAge",
      "value": "{{$[0].age}}"
    }
  ]
}

$ is a shorthand for the tool's response body. $[0] is the first item in the array. $[n] is the nth item in the array. Note, $ is available regardless of the response body type (both object and array).

Use aliases to extract variables from the tool's response headers.

{
  "aliases": [
    {
      "key": "customerName",
      "value": "{{tool.response.headers.customer-name}}"
    },
    {
      "key": "customerAge",
      "value": "{{tool.response.headers.customer-age}}"
    }
  ]
}

tool.response is made available to the liquid template. Particularly, both tool.response.headers and tool.response.body are available. Note, tool.response is available regardless of the response body type (both object and array).

Use schema to extract a large portion of the tool's response body.

4.1. If you hit example.com and it returns {"name": "John", "age": 30}, then you can specify the schema as:

{
  "schema": {
    "type": "object",
    "properties": {
      "name": {
        "type": "string"
      },
      "age": {
        "type": "number"
      }
    }
  }
}

4.2. If you hit example.com and it returns {"name": {"first": "John", "last": "Doe"}}, then you can specify the schema as:

{
  "schema": {
    "type": "object",
    "properties": {
      "name": {
        "type": "object",
        "properties": {
          "first": {
            "type": "string"
          },
          "last": {
            "type": "string"
          }
        }
      }
    }
  }
}

These will be extracted as {{ name }} and {{ age }} respectively. To emphasize, object properties are extracted as direct global variables.

4.3. If you hit example.com and it returns {"name": {"first": "John", "last": "Doe"}}, then you can specify the schema as:

{
  "schema": {
    "type": "object",
    "properties": {
      "name": {
        "type": "object",
        "properties": {
          "first": {
            "type": "string"
          },
          "last": {
            "type": "string"
          }
        }
      }
    }
  }
}

These will be extracted as {{ name }}. And, {{ name.first }} and {{ name.last }} will be accessible.

4.4. If you hit example.com and it returns ["94123", "94124"], then you can specify the schema as:

{
  "schema": {
    "type": "array",
    "title": "zipCodes",
    "items": {
      "type": "string"
    }
  }
}

This will be extracted as {{ zipCodes }}. To access the array items, you can use {{ zipCodes[0] }} and {{ zipCodes[1] }}.

4.5. If you hit example.com and it returns [{"name": "John", "age": 30, "zipCodes": ["94123", "94124"]}, {"name": "Jane", "age": 25, "zipCodes": ["94125", "94126"]}], then you can specify the schema as:

{
  "schema": {
    "type": "array",
    "title": "people",
    "items": {
      "type": "object",
      "properties": {
        "name": {
          "type": "string"
        },
        "age": {
          "type": "number"
        },
        "zipCodes": {
          "type": "array",
          "items": {
            "type": "string"
          }
        }
      }
    }
  }
}

This will be extracted as {{ people }}. To access the array items, you can use {{ people[n].name }}, {{ people[n].age }}, {{ people[n].zipCodes }}, {{ people[n].zipCodes[0] }} and {{ people[n].zipCodes[1] }}.

Note: Both aliases and schema can be used together.

Show child attributes

results.assistant.model.tools.variableExtractionPlan.schema

object

This is the schema to extract.

Examples:

To extract object properties, you can use the following schema:

{
  "type": "object",
  "properties": {
    "name": {
      "type": "string"
    },
    "age": {
      "type": "number"
    }
  }
}

These will be extracted as {{ name }} and {{ age }} respectively. To emphasize, object properties are extracted as direct global variables.

To extract nested properties, you can use the following schema:

{
  "type": "object",
  "properties": {
    "name": {
      "type": "object",
      "properties": {
        "first": {
          "type": "string"
        },
        "last": {
          "type": "string"
        }
      }
    }
  }
}

These will be extracted as {{ name }}. And, {{ name.first }} and {{ name.last }} will be accessible.

To extract array items, you can use the following schema:

{
  "type": "array",
  "title": "zipCodes",
  "items": {
    "type": "string"
  }
}

This will be extracted as {{ zipCodes }}. To access the array items, you can use {{ zipCodes[0] }} and {{ zipCodes[1] }}.

To extract array of objects, you can use the following schema:

{
  "type": "array",
  "name": "people",
  "items": {
    "type": "object",
    "properties": {
      "name": {
        "type": "string"
      },
      "age": {
        "type": "number"
      },
      "zipCodes": {
        "type": "array",

string[]

This array specifies the allowed values that can be used to restrict the output of the model.

results.assistant.model.tools.variableExtractionPlan.schema.title

string

This is the title of the schema.

results.assistant.model.tools.variableExtractionPlan.aliases

object[]

These are additional variables to create.

These will be accessible during the call as {{key}} and stored in call.artifact.variableValues after the call.

Example:

{
  "aliases": [
    {
      "key": "customerName",
      "value": "{{name}}"
    },
    {
      "key": "fullName",
      "value": "{{firstName}} {{lastName}}"
    },
    {
      "key": "greeting",
      "value": "Hello {{name}}, welcome to {{company}}!"
    },
    {
      "key": "customerEmail",
      "value": "{{addresses[0].city}}"
    },
    {
      "key": "something",
      "value": "{{any liquid}}"
    }
  ]
}

This will create variables customerName, fullName, customerEmail, greeting, and something. To access these variables, you can reference them as {{customerName}}, {{fullName}}, {{customerEmail}}, {{greeting}}, and {{something}}.

object

This is the function definition of the tool.

For endCall, transferCall, and dtmf tools, this is auto-filled based on tool-specific fields like tool.destinations. But, even in those cases, you can provide a custom function definition for advanced use cases.

An example of an advanced use case is if you want to customize the message that's spoken for endCall tool. You can specify a function where it returns an argument "reason". Then, in messages array, you can have many "request-complete" messages. One of these messages will be triggered if the messages[].conditions matches the "reason" argument.

Usage:

If this is not provided and transfer tool messages is not provided, default is "Transferring the call now".
If set to "", nothing is spoken. This is useful when you want to silently transfer. This is especially useful when transferring between assistants in a squad. In this scenario, you likely also want to set assistant.firstMessageMode=assistant-speaks-first-with-model-generated-message for the destination assistant.

This accepts a string or a ToolMessageStart class. Latter is useful if you want to specify multiple messages for different languages through the contents field.

results.assistant.hooks.do.destination.numberE164CheckEnabled

To change this behavior, provide a callerId.
Set to '{{customer.number}}' to always use the customer's number as the caller ID.
Set to '{{phoneNumber.number}}' to always use the phone number of the assistant as the caller ID.
Set to any E164 number to always use that number as the caller ID. This needs to be a number that is owned or verified by your Transport provider like Twilio.

For Twilio, you can read up more here: https://www.twilio.com/docs/voice/twiml/dial#callerid

results.assistant.messagePlan

object

This is the plan for static predefined messages that can be spoken by the assistant during the call, like idleMessages.

Note: firstMessage, voicemailMessage, and endCallMessage are currently at the root level. They will be moved to messagePlan in the future, but will remain backwards compatible.

Show child attributes

results.assistant.messagePlan.idleMessages

string[]

This are the messages that the assistant will speak when the user hasn't responded for idleTimeoutSeconds. Each time the timeout is triggered, a random message will be chosen from this array.

Usage:

If user gets distracted and doesn't respond for a while, this can be used to grab their attention.
If the transcriber doesn't pick up what the user said, this can be used to ask the user to repeat themselves. (From the perspective of the assistant, the conversation is idle since it didn't "hear" any user messages.)

@default null (no idle message is spoken)

Maximum string length: 1000

results.assistant.messagePlan.idleMessageMaxSpokenCount

number

This determines the maximum number of times idleMessages can be spoken during the call.

@default 3

Required range: 1 <= x <= 10

@default 10

Required range: 5 <= x <= 60

results.assistant.messagePlan.silenceTimeoutMessage

string

This is the message that the assistant will say if the call ends due to silence.

If unspecified, it will hang up without saying anything.

Maximum string length: 1000

results.assistant.startSpeakingPlan

object

This is the plan for when the assistant should start talking.

You should configure this if you're running into these issues:

The assistant is too slow to start talking after the customer is done speaking.
The assistant is too fast to start talking after the customer is done speaking.
The assistant is so fast that it's actually interrupting the customer.

Show child attributes

results.assistant.startSpeakingPlan.waitSeconds

number

This is how long assistant waits before speaking. Defaults to 0.4.

This is the minimum it will wait but if there is latency is the pipeline, this minimum will be exceeded. This is intended as a stopgap in case the pipeline is moving too fast.

Example:

If model generates tokens and voice generates bytes within 100ms, the pipeline still waits 300ms before outputting speech.

Usage:

If the customer is taking long pauses, set this to a higher value.
If the assistant is accidentally jumping in too much, set this to a higher value.

@default 0.4

Required range: 0 <= x <= 5

Example:

0.4

results.assistant.startSpeakingPlan.smartEndpointingEnabled

deprecated

Example:

false

results.assistant.startSpeakingPlan.smartEndpointingPlan

cozmox · object

This is the plan for smart endpointing. Pick between cozmox smart endpointing or LiveKit smart endpointing (or nothing). We strongly recommend using livekit endpointing when working in English. LiveKit endpointing is not supported in other languages, yet.

If this is set, it will override and take precedence over transcriptionEndpointingPlan. This plan will still be overridden by any matching customEndpointingRules.

cozmox
Livekit
Custom Endpointing Model

Show child attributes

results.assistant.startSpeakingPlan.smartEndpointingPlan.provider

enum<string>

required

This is the provider for the smart endpointing plan.

Available options:

cozmox,

livekit,

custom-endpointing-model

Example:

"cozmox"

results.assistant.startSpeakingPlan.customEndpointingRules

(Assistant · object | Customer · object | Both · object)[]

These are the custom endpointing rules to set an endpointing timeout based on a regex on the customer's speech or the assistant's last message.

Usage:

If you have yes/no questions like "are you interested in a loan?", you can set a shorter timeout.
If you have questions where the customer may pause to look up information like "what's my account number?", you can set a longer timeout.
If you want to wait longer while customer is enumerating a list of numbers, you can set a longer timeout.

These rules have the highest precedence and will override both smartEndpointingPlan and transcriptionEndpointingPlan when a rule is matched.

The rules are evaluated in order and the first one that matches will be used.

Order of precedence for endpointing:

customEndpointingRules (if any match)
smartEndpointingPlan (if set)
transcriptionEndpointingPlan

@default []

Assistant
Customer
Both

Show child attributes

results.assistant.startSpeakingPlan.customEndpointingRules.type

enum<string>

required

This endpointing rule is based on the last assistant message before customer started speaking.

Flow:

Assistant speaks
Customer starts speaking
Customer transcription comes in
This rule is evaluated on the last assistant message
If a match is found based on regex, the endpointing timeout is set to timeoutSeconds

Usage:

If you have yes/no questions in your use case like "are you interested in a loan?", you can set a shorter timeout.
If you have questions where the customer may pause to look up information like "what's my account number?", you can set a longer timeout.

Available options:

assistant

results.assistant.startSpeakingPlan.customEndpointingRules.regex

string

required

This is the regex pattern to match.

Note:

This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true.

Hot tip:

In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead.
RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, send "^cat$".

results.assistant.startSpeakingPlan.customEndpointingRules.timeoutSeconds

number

required

This is the endpointing timeout in seconds, if the rule is matched.

Required range: 0 <= x <= 15

results.assistant.startSpeakingPlan.customEndpointingRules.regexOptions

object[]

These are the options for the regex match. Defaults to all disabled.

@default []

Show child attributes

results.assistant.startSpeakingPlan.customEndpointingRules.regexOptions.type

enum<string>

required

This is the type of the regex option. Options are:

ignore-case: Ignores the case of the text being matched. Add
whole-word: Matches whole words only.
multi-line: Matches across multiple lines.

Available options:

ignore-case,

whole-word,

multi-line

results.assistant.startSpeakingPlan.customEndpointingRules.regexOptions.enabled

boolean

required

This is whether to enable the option.

@default false

results.assistant.startSpeakingPlan.transcriptionEndpointingPlan

object

This determines how a customer speech is considered done (endpointing) using the transcription of customer's speech.

Once an endpoint is triggered, the request is sent to assistant.model.

Note: This plan is only used if smartEndpointingPlan is not set. If both are provided, smartEndpointingPlan takes precedence. This plan will also be overridden by any matching customEndpointingRules.

Show child attributes

results.assistant.startSpeakingPlan.transcriptionEndpointingPlan.onPunctuationSeconds

number

The minimum number of seconds to wait after transcription ending with punctuation before sending a request to the model. Defaults to 0.1.

This setting exists because the transcriber punctuates the transcription when it's more confident that customer has completed a thought.

@default 0.1

Required range: 0 <= x <= 3

Example:

0.1

results.assistant.startSpeakingPlan.transcriptionEndpointingPlan.onNoPunctuationSeconds

number

The minimum number of seconds to wait after transcription ending without punctuation before sending a request to the model. Defaults to 1.5.

This setting exists to catch the cases where the transcriber was not confident enough to punctuate the transcription, but the customer is done and has been silent for a long time.

@default 1.5

Required range: 0 <= x <= 3

Example:

1.5

results.assistant.startSpeakingPlan.transcriptionEndpointingPlan.onNumberSeconds

number

The minimum number of seconds to wait after transcription ending with a number before sending a request to the model. Defaults to 0.4.

This setting exists because the transcriber will sometimes punctuate the transcription ending with a number, even though the customer hasn't uttered the full number. This happens commonly for long numbers when the customer reads the number in chunks.

@default 0.5

Required range: 0 <= x <= 3

Example:

0.5

results.assistant.stopSpeakingPlan

object

This is the plan for when assistant should stop talking on customer interruption.

You should configure this if you're running into these issues:

The assistant is too slow to recognize customer's interruption.
The assistant is too fast to recognize customer's interruption.
The assistant is getting interrupted by phrases that are just acknowledgments.
The assistant is getting interrupted by background noises.
The assistant is not properly stopping -- it starts talking right after getting interrupted.

Show child attributes

results.assistant.stopSpeakingPlan.numWords

number

This is the number of words that the customer has to say before the assistant will stop talking.

Words like "stop", "actually", "no", etc. will always interrupt immediately regardless of this value.

Words like "okay", "yeah", "right" will never interrupt.

When set to 0, voiceSeconds is used in addition to the transcriptions to determine the customer has started speaking.

Defaults to 0.

@default 0

Required range: 0 <= x <= 10

Example:

0

results.assistant.stopSpeakingPlan.voiceSeconds

number

This is the seconds customer has to speak before the assistant stops talking. This uses the VAD (Voice Activity Detection) spike to determine if the customer has started speaking.

Considerations:

A lower value might be more responsive but could potentially pick up non-speech sounds.
A higher value reduces false positives but might slightly delay the detection of speech onset.

This is only used if numWords is set to 0.

Defaults to 0.2

@default 0.2

Required range: 0 <= x <= 0.5

Example:

0.2

results.assistant.stopSpeakingPlan.backoffSeconds

number

This is the seconds to wait before the assistant will start talking again after being interrupted.

Defaults to 1.

@default 1

Required range: 0 <= x <= 10

Example:

1

results.assistant.stopSpeakingPlan.acknowledgementPhrases

  "ah",
  "yeah okay",
  "yeah sure"
]

results.assistant.stopSpeakingPlan.interruptionPhrases

string[]

These are the phrases that will always interrupt the assistant immediately, regardless of numWords. These are typically phrases indicating disagreement or desire to stop.

Maximum string length: 240

Example:

[
  "stop",
  "shut",
  "up",
  "enough",
  "quiet",
  "silence",
  "but",

results.assistantOverrides.model.tools.variableExtractionPlan

object

This is the plan to extract variables from the tool's response. These will be accessible during the call and stored in call.artifact.variableValues after the call.

Usage:

Use aliases to extract variables from the tool's response body. (Most common case)

{
  "aliases": [
    {
      "key": "customerName",
      "value": "{{customer.name}}"
    },
    {
      "key": "customerAge",
      "value": "{{customer.age}}"
    }
  ]
}

The tool response body is made available to the liquid template.

Use aliases to extract variables from the tool's response body if the response is an array.

{
  "aliases": [
    {
      "key": "customerName",
      "value": "{{$[0].name}}"
    },
    {
      "key": "customerAge",
      "value": "{{$[0].age}}"
    }
  ]
}

Use aliases to extract variables from the tool's response headers.

{
  "aliases": [
    {
      "key": "customerName",
      "value": "{{tool.response.headers.customer-name}}"
    },
    {
      "key": "customerAge",
      "value": "{{tool.response.headers.customer-age}}"
    }
  ]
}

Use schema to extract a large portion of the tool's response body.

4.1. If you hit example.com and it returns {"name": "John", "age": 30}, then you can specify the schema as:

{
  "schema": {
    "type": "object",
    "properties": {
      "name": {
        "type": "string"
      },
      "age": {
        "type": "number"
      }
    }
  }
}

4.2. If you hit example.com and it returns {"name": {"first": "John", "last": "Doe"}}, then you can specify the schema as:

{
  "schema": {
    "type": "object",
    "properties": {
      "name": {
        "type": "object",
        "properties": {
          "first": {
            "type": "string"
          },
          "last": {
            "type": "string"
          }
        }
      }
    }
  }
}

These will be extracted as {{ name }} and {{ age }} respectively. To emphasize, object properties are extracted as direct global variables.

4.3. If you hit example.com and it returns {"name": {"first": "John", "last": "Doe"}}, then you can specify the schema as:

{
  "schema": {
    "type": "object",
    "properties": {
      "name": {
        "type": "object",
        "properties": {
          "first": {
            "type": "string"
          },
          "last": {
            "type": "string"
          }
        }
      }
    }
  }
}

These will be extracted as {{ name }}. And, {{ name.first }} and {{ name.last }} will be accessible.

4.4. If you hit example.com and it returns ["94123", "94124"], then you can specify the schema as:

{
  "schema": {
    "type": "array",
    "title": "zipCodes",
    "items": {
      "type": "string"
    }
  }
}

This will be extracted as {{ zipCodes }}. To access the array items, you can use {{ zipCodes[0] }} and {{ zipCodes[1] }}.

{
  "schema": {
    "type": "array",
    "title": "people",
    "items": {
      "type": "object",
      "properties": {
        "name": {
          "type": "string"
        },
        "age": {
          "type": "number"
        },
        "zipCodes": {
          "type": "array",
          "items": {
            "type": "string"
          }
        }
      }
    }
  }
}

Note: Both aliases and schema can be used together.

Show child attributes

results.assistantOverrides.model.tools.variableExtractionPlan.schema

object

This is the schema to extract.

Examples:

To extract object properties, you can use the following schema:

{
  "type": "object",
  "properties": {
    "name": {
      "type": "string"
    },
    "age": {
      "type": "number"
    }
  }
}

These will be extracted as {{ name }} and {{ age }} respectively. To emphasize, object properties are extracted as direct global variables.

To extract nested properties, you can use the following schema:

{
  "type": "object",
  "properties": {
    "name": {
      "type": "object",
      "properties": {
        "first": {
          "type": "string"
        },
        "last": {
          "type": "string"
        }
      }
    }
  }
}

These will be extracted as {{ name }}. And, {{ name.first }} and {{ name.last }} will be accessible.

To extract array items, you can use the following schema:

{
  "type": "array",
  "title": "zipCodes",
  "items": {
    "type": "string"
  }
}

This will be extracted as {{ zipCodes }}. To access the array items, you can use {{ zipCodes[0] }} and {{ zipCodes[1] }}.

To extract array of objects, you can use the following schema:

{
  "type": "array",
  "name": "people",
  "items": {
    "type": "object",
    "properties": {
      "name": {
        "type": "string"
      },
      "age": {

This is spoken to the customer before connecting them to the destination.

Usage:

If this is not provided and transfer tool messages is not provided, default is "Transferring the call now".
If set to "", nothing is spoken. This is useful when you want to silently transfer. This is especially useful when transferring between assistants in a squad. In this scenario, you likely also want to set assistant.firstMessageMode=assistant-speaks-first-with-model-generated-message for the destination assistant.

This accepts a string or a ToolMessageStart class. Latter is useful if you want to specify multiple messages for different languages through the contents field.

results.assistantOverrides.hooks.do.destination.numberE164CheckEnabled

boolean

default:true

This is the flag to toggle the E164 check for the number field. This is an advanced property which should be used if you know your use case requires it.

Use cases:

false: To allow non-E164 numbers like +001234567890, 1234, or abc. This is useful for dialing out to non-E164 numbers on your SIP trunks.
true (default): To allow only E164 numbers like +14155551234. This is standard for PSTN calls.

If false, the number is still required to only contain alphanumeric characters (regex: /^\+?[a-zA-Z0-9]+$/).

@default true (E164 check is enabled)

results.assistantOverrides.hooks.do.destination.extension

string

This is the extension to dial after transferring the call to the number.

Required string length: 1 - 10

results.assistantOverrides.hooks.do.destination.callerId

string

This is the caller ID to use when transferring the call to the number.

Usage:

If not provided, the caller ID will be the number the call is coming from. Example, +14151111111 calls in to and the assistant transfers out to +16470000000. +16470000000 will see +14151111111 as the caller.
To change this behavior, provide a callerId.
Set to '{{customer.number}}' to always use the customer's number as the caller ID.
Set to '{{phoneNumber.number}}' to always use the phone number of the assistant as the caller ID.
Set to any E164 number to always use that number as the caller ID. This needs to be a number that is owned or verified by your Transport provider like Twilio.

For Twilio, you can read up more here: https://www.twilio.com/docs/voice/twiml/dial#callerid

Example:

"cozmox"

results.assistantOverrides.startSpeakingPlan.customEndpointingRules

(Assistant · object | Customer · object | Both · object)[]

These are the custom endpointing rules to set an endpointing timeout based on a regex on the customer's speech or the assistant's last message.

Usage:

If you have yes/no questions like "are you interested in a loan?", you can set a shorter timeout.
If you have questions where the customer may pause to look up information like "what's my account number?", you can set a longer timeout.
If you want to wait longer while customer is enumerating a list of numbers, you can set a longer timeout.

These rules have the highest precedence and will override both smartEndpointingPlan and transcriptionEndpointingPlan when a rule is matched.

The rules are evaluated in order and the first one that matches will be used.

Order of precedence for endpointing:

customEndpointingRules (if any match)
smartEndpointingPlan (if set)
transcriptionEndpointingPlan

@default []

Assistant
Customer
Both

Show child attributes

results.assistantOverrides.startSpeakingPlan.customEndpointingRules.type

enum<string>

required

This endpointing rule is based on the last assistant message before customer started speaking.

Flow:

Assistant speaks
Customer starts speaking
Customer transcription comes in
This rule is evaluated on the last assistant message
If a match is found based on regex, the endpointing timeout is set to timeoutSeconds

Usage:

If you have yes/no questions in your use case like "are you interested in a loan?", you can set a shorter timeout.
If you have questions where the customer may pause to look up information like "what's my account number?", you can set a longer timeout.

Available options:

assistant

results.assistantOverrides.startSpeakingPlan.customEndpointingRules.regex

string

required

This is the regex pattern to match.

Note:

This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true.

Hot tip:

In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead.
RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, send "^cat$".

results.assistantOverrides.startSpeakingPlan.customEndpointingRules.timeoutSeconds

number

required

This is the endpointing timeout in seconds, if the rule is matched.

Required range: 0 <= x <= 15

results.assistantOverrides.startSpeakingPlan.customEndpointingRules.regexOptions

object[]

These are the options for the regex match. Defaults to all disabled.

@default []

Show child attributes

results.assistantOverrides.startSpeakingPlan.customEndpointingRules.regexOptions.type

enum<string>

required

This is the type of the regex option. Options are:

ignore-case: Ignores the case of the text being matched. Add
whole-word: Matches whole words only.
multi-line: Matches across multiple lines.

Available options:

ignore-case,

whole-word,

multi-line

results.assistantOverrides.startSpeakingPlan.customEndpointingRules.regexOptions.enabled

boolean

required

This is whether to enable the option.

@default false

results.assistantOverrides.startSpeakingPlan.transcriptionEndpointingPlan

object

This determines how a customer speech is considered done (endpointing) using the transcription of customer's speech.

Once an endpoint is triggered, the request is sent to assistant.model.

Show child attributes

results.assistantOverrides.startSpeakingPlan.transcriptionEndpointingPlan.onPunctuationSeconds

number

The minimum number of seconds to wait after transcription ending with punctuation before sending a request to the model. Defaults to 0.1.

This setting exists because the transcriber punctuates the transcription when it's more confident that customer has completed a thought.

@default 0.1

Required range: 0 <= x <= 3

Example:

0.1

results.assistantOverrides.startSpeakingPlan.transcriptionEndpointingPlan.onNoPunctuationSeconds

number

The minimum number of seconds to wait after transcription ending without punctuation before sending a request to the model. Defaults to 1.5.

This setting exists to catch the cases where the transcriber was not confident enough to punctuate the transcription, but the customer is done and has been silent for a long time.

@default 1.5

Required range: 0 <= x <= 3

Example:

1.5

results.assistantOverrides.startSpeakingPlan.transcriptionEndpointingPlan.onNumberSeconds

number

The minimum number of seconds to wait after transcription ending with a number before sending a request to the model. Defaults to 0.4.

@default 0.5

Required range: 0 <= x <= 3

Example:

0.5

results.assistantOverrides.stopSpeakingPlan

object

This is the plan for when assistant should stop talking on customer interruption.

You should configure this if you're running into these issues:

The assistant is too slow to recognize customer's interruption.
The assistant is too fast to recognize customer's interruption.
The assistant is getting interrupted by phrases that are just acknowledgments.
The assistant is getting interrupted by background noises.
The assistant is not properly stopping -- it starts talking right after getting interrupted.

Show child attributes

results.assistantOverrides.stopSpeakingPlan.numWords

number

This is the number of words that the customer has to say before the assistant will stop talking.

Words like "stop", "actually", "no", etc. will always interrupt immediately regardless of this value.

Words like "okay", "yeah", "right" will never interrupt.

When set to 0, voiceSeconds is used in addition to the transcriptions to determine the customer has started speaking.

Defaults to 0.

@default 0

Required range: 0 <= x <= 10

Example:

0

results.assistantOverrides.stopSpeakingPlan.voiceSeconds

number

This is the seconds customer has to speak before the assistant stops talking. This uses the VAD (Voice Activity Detection) spike to determine if the customer has started speaking.

Considerations:

A lower value might be more responsive but could potentially pick up non-speech sounds.
A higher value reduces false positives but might slightly delay the detection of speech onset.

This is only used if numWords is set to 0.

Defaults to 0.2

@default 0.2

Required range: 0 <= x <= 0.5

Example:

0.2

results.assistantOverrides.stopSpeakingPlan.backoffSeconds

number

This is the seconds to wait before the assistant will start talking again after being interrupted.

Defaults to 1.

@default 1

Required range: 0 <= x <= 10

Example:

1
