AI phone agents in Serbian

ThunderPhone supports Serbian voice calls, a Serbian dashboard interface, and Serbian product documentation. Serbian is one of the platform's 47 supported voice languages, with six compatible voices in the current catalog.

Serbian voice availability and pricing

The current catalog includes six multilingual voices that support Serbian. It does not currently list a separate Serbian-specific premium-voice set.

Serbian uses a premium language path at +2¢ per minute. That makes the engine-plus-language rate:

  • Spark: 2¢ + 2¢ = 4¢/minute
  • Bolt: 5¢ + 2¢ = 7¢/minute
  • Storm: 9¢ + 2¢ = 11¢/minute

These illustrative figures exclude telephony and any other optional configuration charges. Rates are pay as you go with no subscription, and the agent builder shows the current all-in rate as settings change.

All six voices should be tested with the intended callers. Evaluate names, addresses, numbers, English loanwords, business-specific terminology, and the amount of Serbian-English switching the agent will encounter.

Serbian in the dashboard and documentation

Serbian is a shipped dashboard locale. A team can use the Serbian interface to build agents, review calls, and operate the product.

ThunderPhone also publishes a Serbian 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.

Serbian and English in one call

An agent can start in Serbian and switch automatically when a caller moves to a configured additional language such as English. It can also start in English and switch to Serbian.

The chosen voice must support every selected language. Test realistic switching instead of assuming every code-mixed phrase will behave the same way, especially when callers alternate languages within names, addresses, or technical descriptions.

Sample Serbian call experience

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

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

Caller answers in Serbian: Explains that they need to confirm a service appointment.

Agent continues in Serbian: Requests the caller's name and looks up the approved appointment record.

Caller switches to English: Gives an English company name and asks, "Is the appointment still at three?"

Agent switches to English: Confirms the time and repeats the details for accuracy.

Caller returns to Serbian: Asks what documents to bring to the visit.

Agent returns to Serbian: Answers from the approved knowledge source and offers to repeat the details.

No separate number or manual language-menu choice is required; the whole exchange happens on one line with one agent.

Build and test a Serbian agent

  1. Set Serbian as primary, or add it to an agent's additional languages.
  2. Choose one of the six voices that supports the full selected language set.
  3. Confirm the displayed +2¢ per-minute language surcharge in the builder.
  4. Add reviewed Serbian prompt instructions and source content where exact wording matters.
  5. Run Serbian-only and mixed Serbian-English simulations.
  6. Review pronunciation, transcription, actions, transfers, and fallback behavior before deployment.
