AI phone agents in Greek

ThunderPhone supports Greek voice calls, a Greek dashboard interface, and a Greek edition of the product documentation. A team can build an agent in the Greek dashboard, give callers a natural Greek phone experience, and read localized guidance while doing it.

Greek is one of ThunderPhone's 47 supported voice languages, with eight compatible voices in the current catalog.

Greek voice availability and pricing

The current catalog includes eight voices that support Greek, including two named Greek voices, Despina and Nikos.

Greek uses a premium language path at +3¢ per minute, applied across all Greek-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. The illustrative figures above exclude telephony and any other optional configuration charges; the agent builder shows the current all-in rate as settings change.

Evaluate voices against the calls you actually expect. Test Greek names, street addresses, numbers, English loanwords, and any business-specific terminology your callers use before going live.

Greek in the dashboard and documentation

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

ThunderPhone publishes a Greek 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.

Greek and English in one call

An agent has one primary language and can have additional languages. If Greek is primary and English is additional—or the reverse—the agent switches automatically when the caller changes to a configured language.

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

Sample Greek call experience

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

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

Caller answers in Greek: Explains that they want to reschedule a delivery.

Agent continues in Greek: Confirms the caller's name and looks up the approved delivery record.

Caller switches to English: Gives an English company name and asks, “Can you deliver before noon?”

Agent switches to English: Confirms the earliest available slot and repeats the address for accuracy.

Caller returns to Greek: Asks whether someone needs to sign for the package.

Agent returns to Greek: Answers from the approved knowledge source and repeats the final arrangement.

The switch happens within the same call; the caller never hangs up, presses a phone-tree option, or dials a separate number.

Build and test a Greek agent

1. Set Greek 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 reviewed Greek prompt instructions and approved source content where exact wording matters.
5. Run Greek-only and mixed Greek-English simulations.
6. Review pronunciation, transcripts, tool actions, transfers, and fallback behavior before deployment.
