AI phone agents in Russian

ThunderPhone supports Russian across the customer experience: agents can speak and understand Russian on calls, the dashboard ships with a Russian interface, and the product documentation has a dedicated Russian edition.

Russian is one of ThunderPhone's 47 supported voice languages. It is an included language, so choosing Russian does not add a language surcharge to the selected Spark, Bolt, or Storm engine rate.

Russian voice availability and pricing

The current catalog includes eight voices that support Russian:

• six multilingual voices included on the Russian language path; and
• two premium Russian voices, Natalya and Sergei.

The premium voices add 3¢ per minute; the other compatible voices use the included Russian language path at the base engine rate—Spark 2¢, Bolt 5¢, or Storm 9¢ per minute, pay as you go with no subscription. These illustrative figures exclude telephony and any other optional configuration charges.

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 candidates against the calls you expect: test names, patronymics, street addresses, numbers, English loanwords, and the mix of Russian and English your callers actually use.

Russian in the dashboard and documentation

Russian is a shipped dashboard locale, not just a call setting. A team can work in the Russian interface while configuring prompts, reviewing calls, and managing the organization.

ThunderPhone also publishes a dedicated Russian documentation edition on its docs site, giving Russian-speaking builders localized product guidance in addition to a Russian-speaking agent experience.

Russian and English in one call

An agent has one primary language and can have additional languages. If Russian is primary and English is additional—or the reverse—the agent can switch automatically when the caller changes language mid-call.

The chosen voice must support every selected language. For mixed-language 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 Russian call experience

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

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

Caller answers in Russian: Says they want to move tomorrow's consultation.

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

Caller switches to English: "Actually, can we do a video call instead?"

Agent switches to English: Explains the available options from its approved instructions and asks which the caller prefers.

Caller returns to Russian: Chooses a time and asks for a confirmation message.

Agent returns to Russian: Repeats the final date and time, confirms where the notice will be sent, and closes the call according to the business's instructions.

The language switch happens within the same call; the caller does not need to hang up, pick a phone-tree option, or dial a separate number.

Build and test a Russian agent

1. Set Russian as the primary language, or add it as an additional language.
2. Choose one of the eight voices that supports the complete selected language set.
3. Write the operating prompt in the language your team can review most reliably; the agent's spoken language is configured separately.
4. Attach only approved knowledge and integrations.
5. Run browser tests and simulations with Russian-only, English-only, and mixed-language scenarios.
6. Review transcripts, pronunciation, tool actions, transfers, and escalation behavior before deployment.
