​
voice
string
required

Specifies the voice used in speech synthesis.

  • Define voices using the format <Provider>.<Model>.<VoiceId>. Specifying only the provider will give default values for voice_id and model_id.

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.eleven_multilingual_v2.21m00Tcm4TlvDq8ikWAM). The ModelId part is optional. To use ElevenLabs, you must provide your ElevenLabs API key as an integration identifier secret in "voice_settings": {"api_key_ref": "<secret_identifier>"}. See integration secrets documentation for details. Check available voices.
  • Telnyx: Use Telnyx.<model_id>.<voice_id>

For service_level basic, you may define the gender of the speaker (male or female).

Example:

"Telnyx.KokoroTTS.af"
