AI phone agents in Bengali

ThunderPhone supports Bengali across the product: agents can speak and understand Bengali on calls, the dashboard ships with a Bengali interface, and a Bengali documentation edition is published on the main site.

Bengali is one of ThunderPhone's 47 supported voice languages, with eight compatible voices in the current catalog, including two Bengali voices, Pooja and Rubel.

Bengali voice availability and pricing

The current catalog includes eight voices that support Bengali:

  • six multilingual voices; and
  • two Bengali voices, Pooja and Rubel.

Bengali uses a premium language path at +3¢ per minute across all of its compatible voices. That makes the engine-plus-language rate:

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

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

Every candidate voice should be evaluated against the calls you expect. Test Bengali names, addresses, numbers, English loanwords, business-specific terms, and the amount of Bengali-English switching your callers actually use.

Bengali in the dashboard and documentation

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

ThunderPhone also publishes a Bengali 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 on anything contractual or precise.

Bengali and English in one call

An agent has one primary language and can have additional languages. Set Bengali as primary with English as an additional language—or the reverse—and the agent switches automatically when the caller changes language mid-call.

The chosen voice must support every selected language. Code-mixed Bengali-English conversation is common in many markets, so test the specific transitions your callers make—an English product name inside a Bengali sentence, an address given in English, a question that starts in one language and ends in the other—before going live.

Sample Bengali call experience

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

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

Caller answers in Bengali: Says they want to reschedule tomorrow's delivery.

Agent continues in Bengali: Confirms the caller's name, looks up the approved delivery record, and offers two available windows.

Caller switches to English: “Actually, can you make it Saturday morning instead?”

Agent switches to English: Confirms the Saturday-morning window and repeats the address for accuracy.

Caller returns to Bengali: Confirms the new time and asks whether a phone reminder will be sent.

Agent returns to Bengali: Answers from the approved instructions, repeats the final date and window, and closes the call.

The switch happens within the same call; the caller never hears a phone tree, chooses a language menu, or dials a separate number.

Build and test a Bengali agent

  1. Set Bengali 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. Attach approved knowledge and reviewed Bengali source content where exact wording matters.
  5. Run Bengali-only and mixed Bengali-English simulations, including realistic switch points.
  6. Review pronunciation, transcripts, tool actions, transfers, and escalation behavior before deployment.
