Available Voices

Each TTS model has its own voice catalog. Pick a model first, then choose a voice from that model’s list.

Model	`model` value	Voices	Languages per voice	Audio tags	Catalog
Timbre v3.0	`timbre-v3.0`	13	All 10 languages	Yes	Timbre v3.0 voices
Timbre v2.5	`timbre-v2.5`	42	One preferred language each	—	Timbre v2.5 voices

Voices are not interchangeable between models. A Timbre v2.5 voice (for example Nalini) sent with model: "timbre-v3.0", or a Timbre v3.0 voice (for example Shivani) sent with model: "timbre-v2.5", is rejected with 400 Bad Request. The error message lists the voices the requested model supports.

Preview voices before you integrate. Open the Gnani TTS playground, select a model, and use the filters to narrow by language, gender, and persona.

Audio tags

Timbre v3.0 voices can perform non-verbal cues. Place a tag inline in text at the point where it should happen: <coughs> · <excited> · <exhales> · <giggle> · <laugh> · <pauses> · <shouting> · <sigh> · <slow> · <sniffles> · <whispers> · <yawns> · <clears throat> See Audio Tags for what each tag does.

{
  "text": "Let me check that for you. <pauses> Found it <laugh> your order ships tomorrow.",
  "voice": "Shivani",
  "model": "timbre-v3.0",
  "language": "en-IN"
}

Audio tags are a Timbre v3.0 feature. With timbre-v2.5 they are removed from the text before synthesis and are not spoken; a request whose text contains only tags is rejected with 400 Bad Request.
