AI phone agents in Bulgarian

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

Bulgarian voice availability and pricing

The current catalog includes eight voices that support Bulgarian, among them two dedicated Bulgarian voices, Ivana and Georgi.

Bulgarian 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

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

Test candidate voices with the callers you actually expect. Evaluate Bulgarian names, addresses, numbers, English loanwords, business-specific terminology, and the amount of Bulgarian-English switching the agent will encounter.

Bulgarian in the dashboard and documentation

Bulgarian is a shipped dashboard locale. A team can build agents, review calls, and operate the account entirely in the Bulgarian interface.

ThunderPhone also publishes a Bulgarian 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.

Bulgarian and English in one call

An agent can start in Bulgarian and switch automatically when a caller moves to a configured additional language such as English—or start in English and switch to Bulgarian.

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

Sample Bulgarian call experience

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

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

Caller answers in Bulgarian: Explains that they want to confirm a repair appointment.

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

Caller switches to English: Gives an English product name and asks, "Is the technician still coming at ten?"

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

Caller returns to Bulgarian: Asks what to prepare before the visit.

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

No separate number or manual language-menu choice is required.

Build and test a Bulgarian agent

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