🚀 Step-by-Step Guide
Open the Language Settings panel
Navigate to Settings > Languages. You'll see a list of all 25+ supported languages with toggle switches. English is enabled by default.

Enable your desired languages
Toggle on each language you want to support. For each language, you can select a region-specific dialect (e.g., Spanish - Mexico vs Spanish - Spain). Each dialect uses localized phrasing and pronunciation.
Configure language detection mode
Choose between three modes: 'Auto-Detect' (AI identifies the language from the caller's first sentence), 'Prompt' (AI asks 'Press 1 for English, 2 para Espanol...'), or 'Phone Number Based' (different numbers for different languages).
Translate your business information
For each enabled language, provide translated versions of your business name, services, and FAQs. Click 'Auto-Translate' to generate AI translations, then review and edit. Professional review is recommended for customer-facing terms.

Test each language configuration
Use the Test Call feature and select a target language. Verify the AI greets in the correct language, answers questions accurately, and handles appointment booking in the right language. Pay attention to date/time formatting for each locale.
Set your fallback language
Choose a fallback language for cases where auto-detection fails or the caller speaks an unsupported language. The AI will gracefully transition: 'I apologize, let me continue in English' and switch to the fallback.
Go live and monitor language metrics
Activate multi-language support and monitor the Languages report in Analytics. Track call volume by language, detection accuracy rate, and caller satisfaction scores per language. Adjust configurations based on the data.
💡 Pro Tips
Auto-Detect mode works best when the AI greeting is in your primary language. The caller naturally responds in their preferred language, and the AI switches seamlessly.
Even if you use Auto-Translate, have a native speaker review greetings and common responses. Small cultural nuances make a big difference in caller trust.
Enable mid-call language switching for multilingual households. If a caller starts in Spanish but says 'Can you switch to English?', the AI handles the transition instantly.
Track the Languages report monthly. If a new language consistently appears in 'Unsupported Language' logs, consider adding it to your supported list.
⚠️ Important Warning
Always test your configuration with the built-in simulator before deploying to live callers. Changes to voice settings, routing rules, and workflows take effect within 60 seconds. Monitor the first 5-10 live calls after any change and revert immediately if you notice issues.
