The parameters described as a JSON Schema object that needs to be gathered by the voice assistant. See the JSON Schema reference for documentation about the format
Example:
{ "properties": { "age": { "description": "The age of the customer.", "type": "integer" }, "location": { "description": "The location of the customer.", "type": "string" } }, "required": ["age", "location"], "type": "object" }
The settings associated with speech to text for the voice assistant. This is only relevant if the assistant uses a text-to-text language model. Any assistant using a model with native audio support (e.g. fixie-ai/ultravox-v0_4) will ignore this field.
The voice to be used by the voice assistant. Currently we support ElevenLabs, Telnyx and AWS voices.
Supported Providers:
AWS: Use AWS.Polly.<VoiceId> (e.g., AWS.Polly.Joanna). For neural voices, which provide more realistic, human-like speech, append -Neural to the VoiceId (e.g., AWS.Polly.Joanna-Neural). Check the available voices for compatibility.
Azure: Use Azure.<VoiceId> (e.g., Azure.en-CA-ClaraNeural, Azure.en-CA-LiamNeural, Azure.en-US-BrianMultilingualNeural, Azure.en-US-Ava:DragonHDLatestNeural). For a complete list of voices, go to Azure Voice Gallery.
ElevenLabs: Use ElevenLabs.<ModelId>.<VoiceId> (e.g., ElevenLabs.BaseModel.John). The ModelId part is optional. To use ElevenLabs, you must provide your ElevenLabs API key as an integration secret under "voice_settings": {"api_key_ref": "<secret_id>"}. See integration secrets documentation for details. Check available voices.
Fish Audio: Use FishAudio.<ModelId>.<VoiceId> (e.g., FishAudio.s2.1-pro.<reference_id>). Supported models: s2.1-pro, s2-pro, s1. VoiceId is a Fish Voice-Library reference ID.
Soniox: Use Soniox.<ModelId>.<VoiceId> (e.g., Soniox.tts-rt-v2.Emma). Supported model: tts-rt-v2. Browse the catalog via the Voices API. Every voice speaks all supported languages; set language to the two-letter ISO 639-1 code of the text, for example it. SSML is not supported. Use voice_settings to configure speed (0.7 to 1.3) and reduce_silence.
xAI: Use xAI.<VoiceId> (e.g., xAI.eve). Available voices: eve, ara, rex, sal, leo.
Humain: Use Humain.<VoiceId> (e.g., Humain.sara-ar). Available voices: sara-en, abdulaziz-en, sara-ar, abdulaziz-ar, nourah-ar, abdullah-ar. Native Arabic (Saudi dialect) and English voices only — no ModelId segment.
Text that will be played when the gathering starts, if none then nothing will be played when the gathering starts. The greeting can be text for any voice or SSML for AWS.Polly.<voice_id> voices. There is a 3,000 character limit.
Example:
"Hello, can you tell me your age and where you live?"
Default is false. If set to true, the voice assistant will send partial results via the call.ai_gather.partial_results callback in real time as individual fields are gathered. If set to false, the voice assistant will only send the final result via the call.ai_gather.ended callback.
Default is false. If set to true, the voice assistant will send updates to the message history via the call.ai_gather.message_history_updated callback in real time as the message history is updated.
The message history you want the voice assistant to be aware of, this can be useful to keep the context of the conversation, or to pass additional information to the voice assistant.

For `soniox/stt-rt-v4`, `auto` omits the language hint and lets Soniox auto-detect; ISO 639-1 codes (e.g. `en`, `es`) bias detection toward that language.

For `reson8/turns`, supported values are `auto` (or unset) for automatic language detection, and the language codes `nl`, `en`, `fr`, `fy`, `de`, `it`, `pl`, `pt`, `es`, and `sv` to fix the transcription language. For `cohere/ar-stt`, supported values are `ar` and `en`; unlike other models, this model does not auto-detect and defaults to `ar` when `language` is omitted. For `speechmatics/linden-1`, there is no auto-detect; set a code from Speechmatics' Realtime language list (see `SpeechmaticsTranscriptionLanguage`); unset defaults to `en`, while an explicit `auto`, `auto_beta`, or `multi` is rejected (unlike `speechmatics/standard`, which defaults to `en`).","uniqueKey":"transcription.language","typeLabel":"string"}},"uniqueKey":"transcription","typeLabel":"object"},"language":{"type":"string","title":"Google transcription engine list of languages","description":"Language to use for speech recognition","default":"en","enum":["af","sq","am","ar","hy","az","eu","bn","bs","bg","my","ca","yue","zh","hr","cs","da","nl","en","et","fil","fi","fr","gl","ka","de","el","gu","iw","hi","hu","is","id","it","ja","jv","kn","kk","km","ko","lo","lv","lt","mk","ms","ml","mr","mn","ne","no","fa","pl","pt","pa","ro","ru","rw","sr","si","sk","sl","ss","st","es","su","sw","sv","ta","te","th","tn","tr","ts","uk","ur","uz","ve","vi","xh","zu"],"example":"en","uniqueKey":"language","typeLabel":"enum\u003cstring>"},"voice":{"description":"The voice to be used by the voice assistant.

For neural voices, which provide more realistic, human-like speech, append `-Neural` to the `VoiceId` (e.g., `AWS.Polly.Joanna-Neural`). Check the [available voices](https://docs.aws.amazon.com/polly/latest/dg/available-voices.html) for compatibility.\n- **Azure:** Use `Azure.\u003cVoiceId>` (e.g., `Azure.en-CA-ClaraNeural`, `Azure.en-CA-LiamNeural`, `Azure.en-US-BrianMultilingualNeural`, `Azure.en-US-Ava:DragonHDLatestNeural`). For a complete list of voices, go to [Azure Voice Gallery](https://speech.microsoft.com/portal/voicegallery).\n- **ElevenLabs:** Use `ElevenLabs.\u003cModelId>.\u003cVoiceId>` (e.g., `ElevenLabs.BaseModel.John`). The `ModelId` part is optional. To use ElevenLabs, you must provide your ElevenLabs API key as an integration secret under `\"voice_settings\": {\"api_key_ref\": \"\u003csecret_id>\"}`. See [integration secrets documentation](https://developers.telnyx.com/api/secrets-manager/integration-secrets/create-integration-secret) for details.

Supported models: `Mini`, `Max`, `TTS2`.\n- **Fish Audio:** Use `FishAudio.\u003cModelId>.\u003cVoiceId>` (e.g., `FishAudio.s2.1-pro.\u003creference_id>`). Supported models: `s2.1-pro`, `s2-pro`, `s1`. `VoiceId` is a Fish Voice-Library reference ID.\n- **Soniox:** Use `Soniox.\u003cModelId>.\u003cVoiceId>` (e.g., `Soniox.tts-rt-v2.Emma`). Supported model: `tts-rt-v2`. Browse the catalog via the [Voices API](https://developers.telnyx.com/api-reference/text-to-speech-commands/list-available-voices). Every voice speaks all supported languages; set `language` to the two-letter ISO 639-1 code of the text, for example `it`. SSML is not supported. Use `voice_settings` to configure `speed` (0.7 to 1.3) and `reduce_silence`.\n- **xAI:** Use `xAI.\u003cVoiceId>` (e.g., `xAI.eve`). Available voices: `eve`, `ara`, `rex`, `sal`, `leo`.\n- **Humain:** Use `Humain.\u003cVoiceId>` (e.g., `Humain.sara-ar`).
