AI phone agents in Dutch
ThunderPhone supports Dutch across the customer experience: agents can speak and understand Dutch on calls, the dashboard ships with a Dutch interface, and the product documentation has a dedicated Dutch edition.
Dutch is one of ThunderPhone's 47 supported voice languages. It is an included language, so choosing Dutch does not add a language surcharge to the selected Spark, Bolt, or Storm engine rate.
Dutch voice availability and pricing
The current catalog includes eight voices that support Dutch:
- six multilingual voices on the included Dutch language path; and
- two premium Dutch voices, Noa and Thijs.
The two premium voices add 3¢ per minute to the selected engine rate; the other compatible voices carry no language charge on top of the Spark (2¢), Bolt (5¢), or Storm (9¢) per-minute rate. All figures are before telephony and other optional charges, and pricing is pay as you go with no subscription. The voice picker filters the catalog to voices that support every language selected for the agent, and each voice can be previewed in the builder before deployment.
Evaluate voices against the calls you actually expect. Test Dutch names and place names, street addresses, postcodes and phone numbers, business-specific terminology, English loanwords, and the amount of Dutch-English switching your callers really use.
Dutch in the dashboard and documentation
Dutch is a shipped dashboard locale, not just a call setting. A team can write prompts, review calls and transcripts, and manage the organization entirely in the Dutch interface.
ThunderPhone also publishes a dedicated Dutch documentation edition on its docs site, giving Dutch-speaking builders localized product guidance alongside the Dutch-speaking agent experience.
Dutch and English in one call
An agent has one primary language and can have additional languages. If Dutch is primary and English is additional—or the reverse—the agent switches automatically when the caller changes language during the call.
The chosen voice must support every selected language. Dutch conversation absorbs English words freely, so test realistic code-switching—email addresses, product names, technical descriptions—before going live rather than assuming every mixed phrase will behave the same way.
Sample Dutch call experience
The following flow is written in English to describe the caller experience, not to prescribe exact translated wording.
Agent starts in Dutch: Greets the caller, identifies the business, and asks how it can help.
Caller answers in Dutch: Says they want to change tomorrow's installation appointment.
Agent continues in Dutch: Confirms the caller's name and address, looks up the approved scheduling action, and offers two available times.
Caller switches to English: "Actually, could you email the confirmation to my work address?"
Agent switches to English: Reads the email address back and confirms where the notice will be sent.
Caller returns to Dutch: Confirms the new appointment time.
Agent returns to Dutch: Repeats the final date and time, then ends the call according to the business's instructions.
The switch happens within the same call; the caller does not hang up, choose a phone-tree option, or dial a separate number.

- Review transcripts, pronunciation, tool actions, transfers, and escalation behavior before deployment.
