For businesses whose callers speak Hindi, Tamil, Telugu, Kannada, Malayalam, Marathi, Bengali or another Indian language: the sarvam engine runs Sarvam's Saaras speech recognition, the Sarvam-105B model and the Bulbul voice as one pipeline, priced from the same book as every other engine and billed per second from one prepaid balance.

The engine to use
sarvam, $0.0623 per connected minute. The stt provider selects the pipeline, and Sarvam's models are trained on Indian languages and accents rather than adapted from English. It is the engine to reach for whenever the caller's first language is not English.
What it costs
Engine time for 3-minute calls on the sarvam engine, at typical speech rates. Telephony is your own trunk at your carrier’s rate and is not included; the meter charges per second, so shorter calls cost proportionally less.
| Calls per month | Connected minutes | Engine cost per month |
|---|---|---|
| 500 | 1,500 | $93.45 |
| 2,500 | 7,500 | $467 |
| 10,000 | 30,000 | $1,869 |
Prepaid: add credit from $5 and the calls spend it. Estimate your own mix.
Frequently asked questions
- Does Wixzel Phone support Hindi voice agents?
- Yes. The sarvam engine runs Sarvam's Saaras v3 speech-to-text, the Sarvam-105B language model and the Bulbul v3 voice, all built for Indian languages including Hindi. Set the language on the stt stage of the agent.
- Which Indian languages does the sarvam engine cover?
- The languages supported by Sarvam's Saaras, Sarvam-105B and Bulbul models, which include Hindi, Tamil, Telugu, Kannada, Malayalam, Marathi, Bengali, Gujarati, Punjabi and Odia. Check Sarvam's current model documentation for the full and up-to-date list; Wixzel Phone does not restrict it further.
- What does a minute in Hindi cost?
- $0.0623 per connected minute at typical speech rates on the sarvam engine, including the orchestration fee, plus your carrier's rate for the trunk.
- Can the agent switch between English and an Indian language mid-call?
- Within what the models handle, yes: Sarvam's models cope with code-mixed speech such as Hinglish. A hard switch to the classic engine mid-call is not possible; the engine is fixed when the call is admitted.
- Is Indian phone data kept in India?
- Sarvam processes speech and text in India during the call. The call log, transcript and any recording are stored on the platform's servers in Finland. See the Privacy Policy and DPA for the full list of processors and locations.
