Internationalization (i18n)
These are the voices and dialects for the languages we support:
W2H Locale (code) | Twilio Language | Twilio Voice |
|---|---|---|
English (en) | en-US | Polly.Joanna |
Spanish (es) | es-US | Polly.Penelope |
Russian (ru) | ru-RU | Polly.Tatyana |
Korean (ko) | ko-KR | Polly.Seoyeon |
Twilio has support for many other language and voice combinations. Their documentation can be found here → Available voices and languages.
The language and voice used for the caller are based on the locale of the participant. Just like i18n in messaging, when phrases are not available in the caller’s locale, English is the fallback.
