Text-to-Speech (TTS)

TTS models and voices available through Telnyx for LiveKit voice agents.

Telnyx offers an extensive library of voices across multiple providers and models, with broad language and accent support. Access them through the Telnyx plugin:

tts = telnyx.TTS(voice="Telnyx.NaturalHD.astra")
