13331: Gather: Invalid language value

Use this warning to fix a <Gather> language value that is invalid for the selected speechModel, or a combination Twilio can't map to a supported provider language. Twilio passes the language value through to the provider, and when the selected language and model aren't supported, Twilio generates an error notification and the gather fails.

• You used a malformed locale value such as en instead of a supported tag like en-US.
• The language value isn't supported for the selected speechModel.
• The combination of language, provider, and model isn't supported, so Twilio can't route the request to a compatible speech-to-text language.

• Set language to a value supported by the provider and model you selected.
• Verify that language and speechModel are compatible before you deploy the TwiML.
• Retest the <Gather> flow after you update the configuration, and review the error notification if the warning persists.
