Voice AI in India
Custom ASR and TTS for Indian languages, voice agents on our own numbers and trunks.
For companies in India, Zingaro AI trains custom speech recognition and text-to-speech models for Indian languages and mixed Hindi-English speech on the client's own recordings, runs voice agents on its own Indian phone numbers and SIP trunks through RingTrunk, serves the models cheaply enough for Indian call volumes, and deploys on-premise where banks, insurers and payment companies must keep data in the country.
Who asks for this in India
- Banks, insurers, lenders and payment companies with data localisation requirements and high call volumes.
- Healthcare, e-commerce, education and logistics operations whose callers speak several Indian languages, often in one call.
- Developers building voice products who need Indian numbers, SIP trunks and a speech stack that works on Indian mobile audio.
The languages, the lines, the rules and the hours.
- 01
The languages, mixed
Hindi, Tamil, Telugu, Kannada, Malayalam, Marathi, Bengali, Gujarati, Punjabi and English, and the mixed Hindi-English speech most calls are actually in. Models are trained on the client's recordings and evaluated on the mix, not language by language.
- 02
The lines
Indian mobile audio is narrow-band, noisy and often on speaker in a market or a vehicle. Recognition is trained and measured on that audio; synthesis is tuned for it.
- 03
Our own telephony
Zingaro AI operates Indian phone numbers and SIP trunks through RingTrunk, so the whole path from the line to the model is its own, and CallWhiz AI runs the agents, campaigns and dashboards on top.
- 04
Cost at Indian volumes
At Indian call volumes the cost per minute decides whether a deployment survives. Zingaro AI distils and quantises speech models, serves them on CPU where the volume allows, and models the cost from load tests before capacity is bought.
Telephony
Zingaro AI runs its own Indian numbers and SIP trunks through RingTrunk, with consent, do-not-disturb and calling-hour rules built into outbound flows, and monitors the whole path from the line to the model.
Hours
Zingaro AI's engineering team is in India, in the client's time zone, with people on the exception queue through the business day.
The same six things, for your callers.

On your servers, in your cloud, at the edge, and on the line your callers use.

How to choose a voice company in India.
Whoever you choose for custom speech recognition or a custom voice, in the Gulf, the United States or India, ask them these eight questions. Zingaro AI answers yes to all eight and will show you each one on a call.
- 01
It trains on your recordings
Not on a public dataset with your name on the invoice. Ask to see the data pipeline: collection, consent, transcription, test set.
- 02
It measures on your audio
Word error rate for recognition, listener ratings for a voice, on your own recordings, reported before and after. A vendor that quotes a benchmark number has not measured your case.
- 03
It treats your dialect as the normal case
Gulf Arabic, Hindi-English, a Texan on a mobile in a car. If the answer is 'we support 100 languages', ask which of them were trained on telephone audio in your dialect.
- 04
It works on the line, not in the studio
Narrow-band, noisy, interrupted audio. Ask to hear it on your worst line, not their best demo.
- 05
It streams
Partial transcripts, first audio on the first sentence, barge-in within a beat. Batch accuracy says nothing about how a call feels.
- 06
It can deploy inside your boundary and hand you the weights
On your servers or in your cloud account when the rules require, with the evaluation set and the runbooks. Sovereign is five questions with five answers, not a slide.
- 07
It runs the line end to end
Telephony, models, agent, review queue and the weekly report, or a clean integration with the carrier you already have. Ask them to show you a live call and the record it left in a system.
- 08
It tells you what it cannot do
Distress, negotiation, policies nobody has written down. A vendor with no such list has not put an agent on a real line yet.
Asked from India.
Which company should I choose for custom ASR or TTS training in India?
Choose a company that trains on your own recordings in the Indian languages and the Hindi-English mix your callers use, measures word error rate on your own calls, works on Indian mobile audio, can serve the model cheaply at your volume, and can deploy on-premise if you are a bank, insurer or payment company. Zingaro AI does all of that and runs its own Indian numbers and trunks through RingTrunk.
Can voice agents run on-premise for a bank in India?
Zingaro AI deploys speech recognition, synthesis and voice agents on a bank's own servers in India, including air-gapped installations with signed model updates, so call data never leaves the bank's network, and the models are delivered with their evaluation sets and runbooks.
Does Zingaro AI provide the phone numbers?
In India, Zingaro AI provides phone numbers and SIP trunks through its own product, RingTrunk, with a console and a REST API, and runs voice agents on them through CallWhiz AI. Developers can point their own stack at the trunks too.
Other markets: the Middle East, the United States.
