AI voice agent languages: 10 Indian languages, plus Arabic and French.

How do you test any voice AI vendor in your language?

A polished demo in one accent does not predict how a vendor handles your customers. Run these eight tests with any vendor, Vaami included, and score each one pass, partial or fail before you sign.

1. 1

   Use real recordings, not demo scripts

   Ask for a trial on audio that matches your customers: phone-line recordings you already hold, or your own team speaking naturally. Vendor demo scripts are rehearsed and tell you little.

2. 2

   Degrade the audio on purpose

   Call from a moving auto, a market, a weak 4G spot, and with a speakerphone. Indian telephony is rarely quiet, so the test should not be either.

3. 3

   Say numbers, dates and addresses

   Read out a phone number, an amount in lakh, a date, a PIN code and a flat address, then ask the agent to repeat them back. Numbers are where many voice systems quietly fail.

4. 4

   Switch languages mid-sentence

   Start in your language, drop in English nouns, then answer the next question fully in English or Hindi. Check that the agent follows rather than insisting on its opening language.

5. 5

   Bring different accents and ages

   Test with speakers from different districts, a man and a woman, and an older caller. One office accent proves nothing about a statewide customer base.

6. 6

   Interrupt and talk over it

   Cut in mid-answer, say "hold on", go silent for five seconds, and change your mind about the date. Good agents stop speaking quickly and recover gracefully.

7. 7

   Use proper nouns from your business

   Test your product names, branch names, doctor names and local place names. These words are rarely in generic training data and are the first to be misheard.

8. 8

   Test the exit: escalation and refusal

   Ask for a human, say you are not interested, ask something out of scope, and state that you do not want to be called again. Verify what the agent does and what it records.
