AI phone agents in Indonesian

ThunderPhone supports Indonesian across the product: agents can speak and understand Indonesian on calls, the dashboard ships an Indonesian interface, and the docs site has a dedicated Indonesian edition. Indonesian is one of the platform's 47 supported voice languages, with eight compatible voices in the current catalog.

Pricing stays pay as you go, with no subscription: pick a Spark, Bolt, or Storm engine and pay per minute of talk time.

Indonesian voice availability and pricing

The current catalog includes eight voices that support Indonesian, including two premium Indonesian voices, Siti and Andi.

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

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

These illustrative figures exclude telephony and any other optional configuration charges. The agent builder shows the current all-in rate as settings change.

Evaluate candidate voices against the calls you actually expect. Test Indonesian names, street addresses, phone numbers, English loanwords, brand terms, and the informal register your callers use, then compare the premium voices against the multilingual options before committing.

Indonesian in the dashboard and documentation

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

ThunderPhone publishes a dedicated Indonesian documentation edition on its docs site, so builders get localized product guidance alongside the Indonesian-speaking agent experience.

Indonesian and English in one call

An agent has one primary language and can have additional languages. Set Indonesian as primary and add English—or the reverse—and the agent switches automatically when the caller changes language mid-call. The caller stays on one line; no phone-tree option or separate number is involved.

The chosen voice must support every selected language. Indonesian callers often mix English into technical or business vocabulary, so test realistic code-switched phrases—product names, job titles, appointment terms—rather than assuming every transition will behave the same way.

Sample Indonesian call experience

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

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

Caller answers in Indonesian: Says they want to reschedule a delivery for tomorrow.

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

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

Agent switches to English: Offers the available Friday-morning window and asks for confirmation.

Caller returns to Indonesian: Confirms the new time.

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

  3. Confirm the displayed +3¢ per-minute language surcharge in the builder.
  4. Attach only approved knowledge sources and integrations, with reviewed Indonesian wording where exact phrasing matters.
  5. Run Indonesian-only and mixed Indonesian-English simulations.
  6. Review pronunciation, transcripts, tool actions, transfers, and escalation behavior before deployment.
