13328: Gather: Invalid maxSpeechTime value

Twilio raises this warning when a <Gather> request includes an invalid maxSpeechTime value. Use speechTimeout to control how long Twilio waits after a pause in speech before stopping recognition. speechTimeout accepts a positive integer or auto.

• Your <Gather> configuration includes maxSpeechTime instead of the documented speechTimeout attribute.
• Your speech timing value is not valid for <Gather>, such as a value that is not a positive integer or auto.
• You set speechModel and used speechTimeout="auto", which Twilio does not support with a model selected.

• Replace maxSpeechTime with speechTimeout in your <Gather> TwiML.
• Set speechTimeout to a positive integer, or use auto only when you are not selecting a speech model.
• If you use speechModel, keep speechTimeout as a positive integer and verify the final TwiML that your application sends to Twilio.
