Tamil AI calling agents for your business

A Tamil AI calling agent calls your customers, or answers when they call, in the Tamil people speak rather than the Tamil they write, with English words where callers use them. It handles reminders, payment follow-ups, order confirmation, lead calls and support, and passes the call to your team when a person is needed.

The Tamil demo agent reminds a customer of a two-wheeler loan EMI due in a few days, for a made-up Chennai finance company. Play the customer: say you will pay, ask for the amount again or ask for more time. This is a live agent with sample data, not a recording. Calls end after 90 seconds; no phone number or sign-up needed.

What it does

Five jobs Tamil calling agents take on first.

Each one is a short, repeatable conversation with a clear outcome, which is where an agent saves a team the most time.

Reminders

Appointment and renewal reminders in spoken Tamil: “நாளைக்கு காலையில பத்தரை மணிக்கு appointment இருக்கு.” Outbound calling campaigns

Payment collections

EMI and bill reminders before and after the due date, with the customer's name checked before any amount is mentioned. Calling windows and retries

Order confirmation

COD and order confirmation for online shops, before dispatch. The AI telecaller

Lead calls

Call back enquiries for loans, courses or property while they are fresh, and transfer the warm ones to your team. Lead calls with CRM write-back

Customer support

Delivery, booking and account questions answered on your number in Tamil or English. AI IVR on your number

Start from a script

How Tamil callers talk

Spoken Tamil is a long way from written Tamil.

Tamil has a wide gap between how it is written and how it is spoken. Written Tamil says வருகிறீர்களா; a caller says வர்றீங்களா. Written இருக்கிறது becomes இருக்கு. An agent that speaks written Tamil sounds like a news reader, so write its sample lines in spoken Tamil, the way your customers say them.

Callers, especially in Chennai, mix English into almost every sentence: “payment pending-ஆ இருக்கு”, “confirm பண்ணுங்க”. Valmiki STT writes that mix down as it is said, and Pāṇini TTS reads Tamil script and the English words in one voice.

Regional speech differs as well: Chennai Tamil, the Tamil of Madurai and Tirunelveli in the south, Kongu Tamil around Coimbatore, and Sri Lankan Tamil, which sounds different again. Speakers understand one another, but the respectful ங்க endings (சொல்லுங்க, வாங்க) are expected on any business call, whichever region the caller is from.

Lines an agent might say

உங்க EMI அஞ்சாம் தேதி due ஆகுது.
Your EMI is due on the 5th.
நாலரை மணிக்கு வர முடியுமா?
Can you come at 4:30?
பன்னிரண்டாயிரத்து ஐநூறு ரூபாய்
₹12,500
ஒன்றரை லட்சம்
1.5 lakh

Numbers, dates and times

Tamil joins numbers into one long word.

Tamil groups amounts in lakhs and crores (லட்சம், கோடி) like the rest of India, and joins a number into one long word: ₹12,500 is பன்னிரண்டாயிரத்து ஐநூறு ரூபாய். Many callers say amounts and times in English anyway, especially in Chennai. Decide which style the agent uses, and write numbers out as words in its instructions so the voice does not have to guess.

Times are built from அரை (half), கால் (quarter) and முக்கால் (three quarters): நாலரை is 4:30, நாலேகால் is 4:15 and நாலே முக்கால் is 4:45. Dates take தேதி (அஞ்சாம் தேதி, the 5th). OTPs, account numbers and phone numbers should be read digit by digit.

How it works

Three models handle every turn of the call.

The caller speaks, Valmiki STT writes it down, Vyas LLM decides the reply, and Pāṇini TTS says it.

01
Valmiki STT listens
Valmiki STT transcribes spoken Tamil and English in the same sentence and detects the language without being told.
02
Vyas LLM decides
Vyas LLM reads the transcript with your instructions and picks the next step: answer, ask one question, use one of your tools, or transfer the call.
03
Pāṇini TTS speaks
Pāṇini TTS answers in a Tamil voice and reads Tamil and English words alike. Clone a native speaker from a 10-second sample for a local accent.
04
Your tools and your team
Agents support MCP and tool calling during a call. The agent can transfer the call live to a person on your team. Every call has a recording and a transcript.

Rules

What the calling rules ask of an AI agent.

An opening line that says so

வணக்கம், இது [நிறுவனம்] சார்பா ஒரு AI assistant call, இந்த call record ஆகுது.

Hello, this is an AI assistant calling for [company], and this call is being recorded.

AI calling is legal in India, and the rules for business calls apply to an AI agent as they do to a person. TRAI now treats every call dialled by software, AI agents included, as an A2P call: from 27 November 2026 the business must declare these calls, and the numbers it calls from, to its telecom operator in advance. Promotional calls must come from 140 numbers, and service calls from banks, insurers and other regulated firms from the 1600 series. Read TRAI's rules on robocalls and commercial calls and TRAI's 140, 1600 and 1601 number series.

For overdue loans, the RBI's recovery directions apply from 1 January 2027: calls only between 08:00 and 19:00, every recovery call recorded and kept for six months, and the debt discussed only with the borrower or guarantor. They do not mention AI, so hold an AI agent to the same standard as a person. See RBI's recovery rules for calls. Most duties for call recordings under the DPDP Rules start on 13 May 2027 (DPDP and call recordings).

Telling the caller in the first line that the call is with an AI agent and is recorded is the simple, safe default everywhere. More openings are in the AI disclosure and recording-notice scripts, and country rules in AI calling rules by country. These are summaries, not legal advice.

Whatever its instructions are written in. Pāṇini reads the text the agent produces, so a prompt with spoken forms such as இருக்கு and வர்றீங்களா gives spoken replies. Give the agent a few sample lines in the register you want.

Yes. Valmiki STT transcribes Tamil and English in the same sentence without being told which is coming, and the agent can answer in the same mix.

Valmiki STT transcribes Sri Lankan Tamil as Tamil, but its accuracy on Sri Lankan speech has not been measured separately. Test with your own callers, and write the agent's sample lines with the words they use.

As நாலரை மணி if its instructions say so. Tamil builds times from அரை, கால் and முக்கால், and many callers say times in English instead. Pick one style and give the agent an example.

Yes. Valmiki STT detects the language on each turn. Say in the agent's instructions whether it should follow the caller into English or stay in Tamil.
