Overview

Retrieve available TTS (Text-to-Speech) providers, models, and voices filtered by language. The TTS engine is the agent’s “voice” — it converts the LLM’s text responses into spoken audio that the caller hears. Each voice entry includes metadata such as gender and a sample audio URL so you can preview voices before selecting one. The language parameter is required. For multilingual agents, pass all language codes together to return only voices that support every language in the set.

Required Permission

Query Parameters

Name	Type	Required	Description
`language`	string	Yes	Filter by one or more language codes. Repeat this parameter for multiple languages (e.g. `?language=en-IN&language=hi-IN`). Returns only voices that support all specified languages.
`providerId`	string	No	Filter results to a specific TTS provider (e.g. `gnani`).

Response Fields

Field	Type	Description
`ttsConfig[].name`	string	Human-readable provider display name.
`ttsConfig[].provider.providerId`	string	TTS provider identifier. Use as the `provider` value in `ttsParams` when updating an agent.
`ttsConfig[].provider.label`	string	Human-readable provider label.
`ttsConfig[].models[].modelId`	string	Model identifier.
`ttsConfig[].models[].label`	string	Human-readable model display name.
`ttsConfig[].models[].supportedLanguages`	string[]	BCP-47 language codes supported by this model.
`ttsConfig[].models[].voices[].voiceId`	string	Voice identifier. Use as the `voice` value in `ttsParams`.
`ttsConfig[].models[].voices[].name`	string	Human-readable voice display name.
`ttsConfig[].models[].voices[].supportedLanguages`	string[]	BCP-47 language codes this specific voice supports.
`ttsConfig[].models[].voices[].isMultilingual`	boolean	Whether this voice can speak across multiple languages.
`ttsConfig[].models[].voices[].gender`	string	Voice gender: `male` or `female`.
`ttsConfig[].models[].voices[].demoAudioUrl`	string	URL to a preview audio clip. Use this to let users listen to the voice before selecting it.
`ttsConfig[].models[].voices[].accent`	string[]	Accent tags associated with this voice.
`ttsConfig[].models[].voices[].tone`	string[]	Tone tags associated with this voice.

Use Cases

Populating a voice selector with audio preview in agent configuration
Filtering TTS voices to only those compatible with the agent’s configured languages
Comparing voice options across providers to best match your brand’s tone
Building a voice gallery or preview feature using sample_audio_url

The language parameter is required. A request without at least one language value will return a 404 error. Use language codes from Get Languages.

For multilingual agents, pass all configured language codes together (e.g. ?language=en-IN&language=hi-IN) to find voices that support every language. This prevents selecting a voice that only works in one of the configured languages.

The provider.providerId and voiceId values map directly to the provider and voice fields in the Update Agent ttsParams object. Use the demoAudioUrl to build an audio preview feature so users can hear voices before committing to a selection.

Save the requestId from every response. You will need it if you contact Inya support to trace a specific request.
