AI phone agents in Tamil

ThunderPhone supports Tamil across the product: agents can speak and understand Tamil on live phone calls, the dashboard ships with a Tamil interface, and a Tamil documentation edition is available. Tamil is one of the platform's 47 supported voice languages, with eight compatible voices in the current catalog.

A team can therefore build in Tamil, operate in Tamil, and answer callers in Tamil without stitching together separate tools for each step.

Tamil voice availability and pricing

The current catalog includes eight voices that support Tamil:

  • six multilingual voices; and
  • two premium Tamil voices, Kavitha and Arun.

Tamil uses a premium language path at +3¢ per minute, which applies to all Tamil-compatible voices. That makes the engine-plus-language rate:

  • Spark: 2¢ + 3¢ = 5¢/minute
  • Bolt: 5¢ + 3¢ = 8¢/minute
  • Storm: 9¢ + 3¢ = 12¢/minute

Pricing is pay as you go with no subscription, and these illustrative figures exclude telephony and other optional charges. The agent builder shows the current all-in rate as settings change.

Voice quality should be judged against the calls you actually expect. Test Tamil and English names, addresses, phone numbers, English loanwords, and business-specific terminology with the voices you shortlist, and preview each candidate in the builder before deployment.

Tamil in the dashboard and documentation

Tamil is a shipped dashboard locale, not just a call setting. A team can configure prompts, review calls and transcripts, and manage the organization entirely in the Tamil interface.

ThunderPhone publishes a Tamil documentation edition served on the main site; it is machine-translated from the governing English docs, so keep the English docs one click away for exact wording.

Tamil and English in one call

An agent starts in its primary language and can switch automatically when a caller uses a configured additional language. Set Tamil as primary with English as additional—or the reverse—and the same agent handles both without a phone tree or a second number.

The chosen voice must support every selected language. Tamil callers often mix English into names, addresses, and technical phrases, so test realistic code-switching rather than assuming every mixed phrase will behave the same way.

Sample Tamil call experience

The following flow is written in English to describe the caller experience.

Agent starts in Tamil: Greets the caller, identifies the business, and asks how it can help.

Caller answers in Tamil: Says they want to reschedule this week's service visit.

Agent continues in Tamil: Confirms the caller's name, looks up the approved scheduling action, and offers two available slots.

Caller switches to English: "Actually, can we do Saturday morning instead?"

Agent switches to English: Offers the available Saturday-morning time and asks for confirmation.

Caller returns to Tamil: Confirms the new time.

Agent returns to Tamil: Repeats the final date and time, then closes the call according to the business's instructions.

The switch happens within the same call; the caller never hangs up or navigates a language menu.

Build and test a Tamil agent

  1. Set Tamil as the primary language, or add it to an agent's additional languages.
  2. Choose one of the eight voices that supports the complete selected language set.
  3. Confirm the displayed +3¢ per-minute language surcharge in the builder.
  4. Write the operating prompt in the language your team can review most reliably, and attach only approved knowledge and integrations.
  5. Run Tamil-only and mixed Tamil-English simulations covering names, numbers, and loanwords your callers actually use.
  6. Review transcripts, pronunciation, tool actions, transfers, and fallback behavior before deployment.
