Dynamic content translation
Translate knowledge base responses or system messages into the caller’s language on-the-fly.Multi-market support
Support callers in multiple languages using a single knowledge base with translated responses.Cross-language handoffs
Prepare translated notes for human agents when transferring non-English speaking callers.Limitations
- API quotas: Free tier has character limits; monitor usage for high-volume deployments
- Voice synthesis: Translated text requires compatible TTS voices for natural delivery
- Context preservation: Complex domain-specific terminology may require custom glossaries
Best practices
- Pre-translate common phrases: For frequently used responses, pre-translate to reduce latency
- Use glossaries: Define translations for brand names, product terms, and industry jargon
- Test thoroughly: Verify translations in all target languages before deployment
