Maya Research is a text-to-speech provider built for Indian languages. The Maya 2 Native model streams speech over a persistent WebSocket, with two voices — Ananya and Arjun — each covering all eleven supported languages.

​
Supported voices

Maya has two voices. Both speak every supported language — voice and language are chosen independently. Voice matching is case-sensitive on Maya’s side — ananya is rejected. Bolna normalizes casing for you, so voice: "ananya" still resolves to Ananya.

​
Supported languages

Region-qualified ASR codes like hi-IN are trimmed down to the primary subtag (hi) automatically. This is also how Bolna switches Maya’s language mid-call — a fresh config frame goes out over the same WebSocket, so the call never reconnects.

How streaming works

A call runs on a single persistent WebSocket connection. Sentence segmentation happens on Maya’s side, so LLM output is forwarded to Maya as it arrives — Bolna does no client-side chunking of the text. Maya only closes out a turn on a flush, so every text fragment is sent as non-final. If the LLM’s final piece of text for a turn is empty, Bolna sends a single whitespace character before the flush — otherwise Maya never emits an end-of-turn event and the turn does not close. On interruption, Bolna sends a clear frame and drops any audio frames that keep arriving until Maya confirms with cancelled.

​
Audio output

Maya streams audio at 24 kHz throughout. Bolna handles the conversion depending on where the audio is going:
  • Telephony — downsampled to 8 kHz and mu-law encoded
  • Web — left at Maya’s native 24 kHz, no resampling
Handoff and prewarm clips are generated with a one-shot HTTP call rather than the WebSocket. On telephony configs, this HTTP response is converted straight to mu-law in-process, skipping the usual transcode step.

FAQ

Both voices cover all eleven supported languages, so the choice is purely about which voice fits your agent’s persona — Ananya (female) or Arjun (male).
Yes. Set language to the code you need, or use auto to let Maya detect it per utterance. Bolna sends language switches as a config update over the existing WebSocket, so the call never reconnects.
No. Codes like hi-IN are automatically reduced to the primary subtag (hi) that Maya expects.
Yes. Bolna downsamples and mu-law encodes Maya’s audio for telephony, and leaves it at native 24 kHz for web.
