Languages and voices
Select and validate speech behavior for multilingual deployments.
Selection workflow
1
Choose the real conversation language
Select the language callers will actually use, not the language used to write the dashboard prompt.
2
Preview the voice
Test representative names, addresses, currency, dates, abbreviations, and industry terminology.
3
Match script and voice
Write native-script content where it improves pronunciation. Avoid inconsistent transliteration.
4
Run phone-quality tests
Browser previews are useful, but final acceptance must use real calls and realistic background noise.
Quality checklist
| Check | Pass condition |
|---|---|
| Accent | Natural and appropriate for the target audience. |
| Numbers | Phone numbers, prices, dates, and times are unambiguous. |
| Code switching | Language changes happen only when requested or clearly needed. |
| Pacing | The caller has enough time to respond without long silence. |
| Pronunciation | Brand and domain-specific words remain consistent. |
