AI phone agents in Portuguese

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

Portuguese is an included language, so choosing it does not add a language surcharge to the selected Spark, Bolt, or Storm engine rate.

Portuguese voice availability and pricing

The current catalog includes eight voices that support Portuguese:

• six multilingual voices on the included Portuguese language path; and
• two premium Portuguese voices, Larissa and Bruno.

There is no language surcharge for Portuguese. The engine rates apply directly—Spark 2¢, Bolt 5¢, and Storm 9¢ per minute, pay as you go with no subscription. The optional premium voices add 3¢ per minute on top of the engine rate. All figures are before telephony and other optional charges, and the agent builder shows the current all-in rate as settings change.

Portuguese spans distinct markets with different accents, vocabulary, and conventions, so test candidate voices with your actual intended callers. Names, addresses, numbers, and the English loanwords your audience uses reveal fit faster than sample clips alone.

Portuguese in the dashboard and documentation

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

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

Portuguese and English in one call

An agent starts in its primary language and switches automatically when a caller uses a configured additional language. Set Portuguese as primary with English additional—or the reverse—and the agent follows the caller within the same call.

The chosen voice must support every selected language. Callers often switch to English for email addresses, product names, or technical explanations, so test those exact transitions with realistic phrasing before going live.

Sample Portuguese call experience

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

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

Caller answers in Portuguese: Says they need to move next week's appointment.

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

Caller switches to English: "Actually, can you send the confirmation to my work email?"

Agent switches to English: Repeats the email address back and confirms where the notice will be sent.

Caller returns to Portuguese: Confirms the new time and asks about arrival instructions.

Agent returns to Portuguese: Answers from the approved knowledge source and repeats the confirmed appointment.

The caller stays on one line with one agent; no separate number or phone-tree language menu is needed.

Build and test a Portuguese agent

1. Set Portuguese as the primary language, or add it as an additional language on an existing agent.
2. Choose one of the eight voices that supports the complete selected language set.
3. Decide whether an included voice or a premium voice (+3¢ per minute) fits the line, and preview candidates in the builder.
4. Attach only approved knowledge sources and integrations, with reviewed Portuguese content where exact wording matters.
5. Run Portuguese-only and mixed Portuguese-English simulations with callers representative of your market.
6. Review transcripts, pronunciation, tool actions, transfers, and escalation behavior before deployment.
