Regional Language Voice Bot

A regional language voice bot holds a natural phone conversation in Hindi, Marathi, Gujarati, Tamil, Telugu, Bengali or Kannada — including the code-mixed Hinglish most Indians actually speak, where half the sentence switches language mid-way.

Where English-only voice quietly fails

In text, a customer who is not confident in English can take their time, re-read, and use a translation app. On a phone call there is no time and no safety net. They either switch to a language they are comfortable in, or they end the call.

So an English-only voice agent does not degrade gracefully outside metro audiences — it fails outright, and it fails silently, because the customer who hung up does not tell you why.

For businesses selling into tier-2 and tier-3 cities, into manufacturing, agriculture, construction or field services, this is not a refinement. It is whether the system works at all.

Code-mixing is the actual engineering problem

The naive picture is a customer speaking clean Marathi and a system that speaks clean Marathi back. Real calls do not sound like that.

A real sentence is "haan woh delivery ka status check karna tha, order number hai..." — Hindi grammar, English nouns, an order number in English digits, and a switch mid-clause. Recognition systems trained on monolingual data fall apart on exactly this, and it is the majority of real traffic.

Handling it means models that were trained on genuine code-mixed Indian speech rather than on translated corpora, and it is the main thing that separates a system that works in production from one that demos well.

Honest quality by language

This varies, it changes as models improve, and any supplier who tells you all languages are equally good has not tested them.

Language	Recognition	Synthesis	Practical verdict
Hindi	Very good	Very good	Near parity with English
Marathi	Good	Good	Strong for transactional calls
Gujarati	Good	Good	Strong; some idiom stiffness
Tamil	Good	Moderate–good	Usable; longer answers read formal
Telugu	Good	Moderate–good	Usable; same caveat
Bengali	Moderate–good	Moderate	Test before committing
Kannada	Moderate	Moderate	Test before committing

We benchmark on your own script and your own call recordings, and we play you the output. If a language is not good enough for your use case, we would rather you launched six than launched seven and had one embarrassing you.

Names, numbers and places

The specific failures in Indian voice systems are rarely grammatical. They are proper nouns.

Indian personal names, place names and street addresses are where recognition breaks — a system that handles conversational Hindi comfortably will still mangle "Ghansoli" or spell a surname three different ways across one call. Numbers spoken in mixed language ("do hazaar paanch sau") are another consistent trip point.

We tune these explicitly with a custom vocabulary of your service areas, product names and the surnames common in your customer base. It is unglamorous work and it is most of the difference between a system customers trust and one they do not.

What it costs and why

Regional language calls run roughly 20–40% above the English baseline of ₹4–₹12 per minute. Recognition and synthesis both cost more, and non-English text consumes more tokens for the same meaning.

That comparison is the wrong one though. The relevant comparison is against the calls you currently lose entirely because the customer could not or would not continue in English.

What is delivered

A voice agent handling your chosen languages with automatic detection, code-mixed speech support, a custom vocabulary for your places, products and names, language-aware routing so the handover reaches someone who can take it, per-language benchmarks measured on your own recordings, and reporting split by language so you can see which are actually being used.

FAQ

Regional Language Voice Bot — your questions

Can one agent handle several languages on the same number?

Yes. Detection happens in the first few seconds and the agent continues in whatever the caller used, switching if they switch mid-call. Separate numbers per language are unnecessary and add operational overhead for no benefit.

How good is Marathi really?

Good for transactional calls — appointments, order status, prices, reminders — and noticeably less natural on long explanatory answers, where phrasing reads more formal than a native speaker would use. We will play you real recordings on your own script so you can judge rather than take our word.

What about accents within the same language?

Regional accent variation is handled reasonably but not perfectly, and it is a real source of error at the margins. Custom vocabulary tuning on your actual customer recordings helps considerably, which is why we ask for real call audio rather than working from a script.

Does the caller know it is an AI?

Yes — the disclosure is in the opening line, in the same language as the rest of the call. We do not translate the disclosure into something vaguer for non-English callers, which is a shortcut we have been asked for and declined.
