What’s changing?

Voice AI agents can now conduct phone conversations in multiple languages with native-sounding accents and region-specific vocabulary.

Key capabilities:

60+ languages with regional variants: Support customers in their preferred language from a single AI agent. 10 languages are available now (English, Portuguese, Spanish, German, French, Dutch, Italian, Polish, Romanian, and Turkish), with 50+ more languages coming soon.

Native-sounding accents: Choose specific regional variants like Mexican Spanish vs. European Spanish, or Brazilian Portuguese vs. European Portuguese to match your customer base.

Fully generative—no translation required: Your procedures, integrations, and knowledge base work automatically in any configured language.

Flexible language routing: Route callers to the right language based on phone number, caller location, user data from your systems, or by asking them directly.

Automatic language switching: Callers can switch languages mid-conversation by simply asking. The AI detects the request and switches if the language is activated.

Regional dialect options: Select the exact accent and vocabulary for your market (e.g., Austrian German, Canadian French, Brazilian Portuguese).

For more information, see Configuring multi-language support for AI agents.

What's coming soon:

High-fidelity voices: Voice configuration will allow you to select premium voices per language for enhanced accent quality and naturalness.

Automatic language detection: The AI agent will automatically detect which language the caller is speaking without requiring explicit configuration.

Additional languages: 50+ additional languages will be rolling out, including Japanese, Chinese, Arabic, Russian, Vietnamese, and more.

Why is Zendesk making this change?

Multilingual voice AI agents enable global support teams to deliver automated phone experiences in their customers' native languages, without building separate systems or translating content.
