Built for how India actually talks.
Pick a primary language and Vocily AI wires the speech-to-text model, voice, and fallback chain to match. 17+ Indian languages, two code-mix auto-modes, and per-language voice binding so your bot stops sounding like an English voice attempting Hindi.
Problem · Solution
The problem today
Most voice AI platforms treat Indian languages as an afterthought — a Hindi voice that's really an English voice with an accent, an STT model that mangles 'Bansal' and 'Bhansali' the same way, and zero awareness when a caller code-mixes mid-sentence. The result is bots that sound foreign on the very calls that need to feel local. Provider config is the other half of the pain: choosing between Sarvam and Deepgram, picking the right Cartesia voice for Tamil, configuring fallbacks if one provider hiccups — every team rebuilds this stack from scratch.
How Vocily AI handles it
Language-first agent setup
Pick your callers' primary language and Vocily AI recommends the best STT model, the right TTS voice, and a sensible fallback. Override anything; the defaults are coherent.
17+ Indian languages with code-mix auto-modes
Hindi, English (Indian/US/UK), Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu, Urdu, Assamese — plus Hinglish auto and Indian Multilingual auto powered by Sarvam saaras:v3.
Mid-call language switching
When a caller flips from English to Hindi at turn three, the agent follows — hot-swapping STT and the TTS voice mid-conversation. No reconnect, no awkward pause.
Per-language TTS voice mapping
Bind a native Hindi voice for Hindi turns and a separate English voice for English turns inside the same agent. Stops the 'English voice attempting Hindi' problem.
Vendor retry + automatic fallback
When a provider hiccups, Vocily AI retries silently with a spoken 'one moment' so callers never hear dead silence. If Sarvam lags more than 5 seconds, Deepgram picks up — buffered audio replayed, switchover silent.
What's in it
What the voice engine ships with.
The configuration surface that lets you tune an agent for real Indian conversations — not just toggle on a generic 'Hindi mode.'

Common questions
What teams ask before they switch.
Yes — if the caller flips from English to Hindi between turns, the agent matches: STT swaps, the TTS voice swaps, the call continues. No reconnect, no replay.
