Can an AI Really Speak Tamil on the Phone?

If you run a clinic, a PG, a tuition centre or a salon in Tamil Nadu, many of your callers speak Tamil, or a mix of Tamil and English that nobody would call textbook. A Tamil voice bot sounds useful on paper, but the only way to know whether it works for your callers is to call it yourself, on your own number, with your own questions. This guide gives you what to check and a 10-point test script you can run during a free trial.

What does it mean for an AI to speak Tamil on a phone call?

A phone call has three jobs happening at once. The system has to hear what the caller said, work out what they want, and reply in a voice that sounds natural enough that the caller keeps talking. A demo that reads a Tamil sentence aloud only proves the last of these.

What matters to you is the whole loop on a real call. Ask yourself these questions as you test:

• Does it understand the caller's Tamil, including the way people in your area actually speak?
• Does it reply in Tamil when the caller speaks Tamil, and switch when the caller switches?
• Does it finish the job, such as booking a slot or passing a message, rather than only sounding fluent?
• Does it hand over to you when it is unsure, instead of guessing?

Anssay's website says it answers calls, WhatsApp and website chat in English, Tamil and Hindi, and that it follows the caller if they switch language mid-call. That is the claim to test. This post makes no promise about how well any system, Anssay included, will perform on your calls. Your own test calls will tell you that.

What should you prepare before you start testing?

Testing goes better with a little preparation. The aim is to compare the AI against what your callers really ask, not against what you imagine they ask.

1. Write down the ten questions callers ask you most. Look at your call log, WhatsApp chats and the notes your staff keep.
2. Note the words you use for your own services, in the form callers say them. A caller may say "scan" or "X-ray" in English even in a Tamil sentence.
3. Decide what a correct answer is for each question, for example your timings, your fee range or your address landmark. You cannot judge an answer you have not written down.
4. Ask two or three people to help: one family member who speaks Tamil at home, one who mixes English, and one from a different part of Tamil Nadu if you can. Different speakers show different gaps.
5. Keep a simple sheet to score each call. A template is further down.

The Anssay website says you can set up by recording a one-minute voice note about your timings, services and prices, and that you keep your existing number. It also says the trial is 14 days, free, with no card.

The pricing page lists the trial allowance as 50 call minutes, 200 AI replies and 100 WhatsApp messages, so plan your test calls to fit inside that. As an example, ten calls of about three minutes each use 30 of the 50 minutes and leave 20 for a second round after you fix any gaps in what you told it.

Two small points before you ask others to help. When friends, staff or customers take part in test calls, tell them the call is a test and why, because India's Digital Personal Data Protection Act, 2023 expects a notice and free, informed consent when personal data is collected. If you also test WhatsApp, message only people who agreed to hear from you, since the WhatsApp Business Policy requires opt-in permission from the recipient.

How do you test Tamil mixed with English (Tanglish)?

Most real calls are not pure Tamil. People say "appointment" and "report" in English, give numbers in English and keep the verbs in Tamil. This mixed style is often called Tanglish. Anssay's pages mention English, Tamil and Hindi and callers switching between them, but they do not say anything specific about Tanglish, so treat it as something to test rather than assume.

Try these patterns:

• A full sentence in Tamil, with one English word in the middle, such as the name of a service.
• A sentence that starts in English and ends in Tamil.
• A Tamil sentence with the date and time in English.
• A caller who answers an English question in Tamil.

Pay attention to what happens after the switch. Does the reply stay sensible? Does it keep the details the caller already gave, or does it ask for them again?

Does it get names, numbers and dates right?

This is where a mistake costs you the most. A wrong phone number or a wrong time is worse than no answer. Test these on purpose:

• Names. Use a Tamil name that is long or has less common spellings, and ask it to confirm the name back to you.
• Phone numbers. Say a ten-digit number at normal speed, once in English digits and once in Tamil. Check the confirmation.
• Dates. Say "next Thursday", "the day after tomorrow" and a date with the month in Tamil.
• Times. Say "half past four", "evening around five" and "after lunch". Confirm what slot it books.
• Amounts. If callers ask about fees, check that it says the amount you gave it, and only that.

For every booking, open your calendar afterwards and compare the entry with what you asked for. A pleasant conversation that books the wrong slot is a failed test.

What about accents, noisy lines and weak networks?

Your callers will not be calling from a quiet room. They call from a bus stop, a kitchen, a two-wheeler or a lift with one bar of network. A test in a silent office tells you very little.

Run a few calls the way your real callers call:

• From a mobile with a weak signal.
• From a noisy place with traffic or a TV on.
• With the speaker on and the phone held a little away.
• With an older relative who speaks slowly and a younger one who speaks fast.
• With someone whose Tamil differs from yours, for example from another district.

Do not expect a perfect score here. What you want to learn is how the system fails. A good failure is the AI saying it did not catch something and asking again, or passing the message to you. A bad failure is the AI confidently continuing with the wrong information.

How does it handle silences, pauses and interruptions?

Callers often think aloud, say "hello, hello" and cut in halfway through a sentence. Phone conversations are not neat turns.

Check these behaviours:

1. Long pause. Stay quiet for several seconds after a question. Does it wait, repeat the question politely, or hang up?
2. Interrupting. Start speaking while it is mid-sentence. Does it stop and listen, or talk over you?
3. Talking to someone else. Say something to a person next to you, as callers often do. Does it get confused?
4. "Hello? Are you there?" Callers often say this when there is a short delay. See whether the call recovers.
5. Repeat request. Say "thirumba sollunga" (please say that again) or ask in English to repeat. Does it repeat clearly?

What is the 10-point Tamil test script?

Use this script for your own number during the free trial. Make each call separately, and write a score and a short note right after.

1. Plain Tamil question. Ask your opening hours in simple Tamil. Check the answer matches what you told it.
2. Plain English question. Ask the same in English. Check that the answer matches the first one.
3. Switch mid-call. Start in Tamil, then switch to English for one question, then go back. Check that it follows without losing the thread.
4. Tanglish sentence. Ask for a booking in a mixed sentence. Check the service and the day are captured.
5. Name check. Give a long Tamil name and ask it to repeat it back.
6. Number check. Give a mobile number and ask it to confirm.
7. Date and time check. Ask for "Thursday evening" and see what slot it offers or books. Verify it in your calendar.
8. Noisy line. Repeat a simple booking from a noisy place or a weak signal.
9. Interruption and silence. Cut in mid-reply, then stay silent for a few seconds.
10. A question you did not teach it. Ask something you left out, such as a special discount. The right behaviour is to pass it to you with context, not to invent an answer.

On the last point, the Anssay website says it answers only from information you have confirmed and sends prices, complaints and new questions to you with context. Point 10 is the quickest way to check that on your own account.

How do you score the calls and decide?

Keep the scoring plain. After each call, fill one row, and look at the whole sheet at the end rather than one bad call. Here is a simple layout you can copy.

Then decide using your own rules. Some owners are happy if routine questions work and everything else reaches them. Others want name and number capture to be nearly perfect before they go live. Decide this before you test, so the results do not talk you into something. If one kind of call keeps failing, such as noisy lines, note it and test again after you adjust the information you gave the system.

Which mistakes make owners misjudge a Tamil voice bot?

• Testing only in your own voice. You speak clearly and know what the system expects. Ask others to call.
• Judging by the first sentence. A fluent greeting says little. The booking and the follow-up matter more.
• Not checking the calendar. The conversation can sound right while the entry is wrong.
• Testing only easy questions. Include the awkward ones, since those are the calls that cost you patients or tenants.
• Expecting zero handovers. Handing a hard question to you is the system working as it should.
• Believing any single accuracy number. A figure from a vendor page rarely matches your callers, your lines or your accents. Your own sheet is the only number that counts.

Where does Anssay fit in?
