The Voices page is the catalogue of every text-to-speech voice available to your agents, across all supported providers. The voice you pick shapes how callers perceive the agent more than almost anything except the prompt.

​
Browsing the catalogue

Filter the catalogue by:
  • Provider — each TTS provider offers different voices, languages, and latency characteristics.
  • Language — match the language your agent speaks. Voices are available for English and major Indian languages (Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Gujarati, Marathi, Punjabi, and more).
  • Gender and accent.
  • Tags — descriptive qualities like warm, energetic, or professional.
Every voice has a preview button — always listen before assigning. A recommended strip at the top surfaces voices that work well for phone audio. Mark voices as favourites (the star) to build a shortlist; a favourites only toggle filters the catalogue down to them.

​
Assigning a voice to an agent

Select a voice from the catalogue, or pick it directly on the agent’s Advanced → Text-to-Speech section. Voice and speech-recognition language are set independently — make sure both match the language your callers actually use.

​
Pronunciation rules

Under Voices → Pronunciation, you can define account-wide pronunciation overrides — a word and how it should be spoken: Rules apply to every agent in your account, which keeps brand names, product names, and abbreviations consistent across all voices. Add a rule whenever you hear an agent mangle a name in a recording.
Test your chosen voice with your actual prompt in the web-call playground, not just the preview clip — some voices that sound great reading a sample sentence stumble on numbers, amounts, or code-mixed Hindi-English.
