AI phone agents in Hindi
ThunderPhone supports Hindi across the customer experience: agents can speak and understand Hindi on calls, the dashboard has a Hindi interface, and the product documentation has a dedicated Hindi edition.
Hindi is one of ThunderPhone's 47 supported voice languages. It is an included language, so choosing Hindi does not add a language surcharge to the selected Spark, Bolt, or Storm engine rate.
Hindi voice options
The current catalog includes eight voices that support Hindi:
- six multilingual voices included on the Hindi language path; and
- two premium Hindi voices with Indian accents.
Premium voices add 3¢ per minute. 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.
Voice quality should be evaluated against the calls you expect to receive. Test names, addresses, technical terms, brand pronunciation, numbers, and the mix of Hindi and English your callers actually use.
Hindi in the dashboard and documentation
Hindi is a shipped dashboard locale, not just a call setting. A user can work in the Hindi interface while configuring prompts, reviewing calls, and managing the organization.
ThunderPhone also publishes a dedicated Hindi documentation tree. That gives Hindi-speaking builders localized product guidance in addition to a Hindi-speaking agent experience.
One call can use more than one language
An agent has one primary language and can have additional languages. If Hindi is primary and English is additional—or the reverse—the agent can switch automatically when the caller changes language.
The selected voice must support all configured languages. For code-mixed conversations, test the phrases and transitions that matter to your audience before going live; automatic switching is not a substitute for reviewing domain-specific pronunciation.
Sample Hindi call experience
The following flow is written in English to show what happens, not to prescribe exact translated wording.
Agent starts in Hindi: Greets the caller, identifies the business, and asks how it can help.
Caller answers in Hindi: Says they want to change tomorrow's appointment.
Agent continues in Hindi: Confirms the caller's name, looks up the approved scheduling action, and offers two available times.
Caller switches to English: “Actually, can you make it Friday afternoon?”
Agent switches to English: Offers the available Friday-afternoon time and asks for confirmation.
Caller returns to Hindi: Confirms the appointment.
Agent returns to Hindi: Repeats the final date and time, then ends the call according to the business's instructions.
The language switch happens within the same call; the caller does not need to hang up, choose a phone-tree option, or reach a separate number.
Build and test a Hindi agent
