13333: Gather: Invalid profanityFilter value

Twilio sends this warning when <Gather> receives an invalid profanityFilter value. Set profanityFilter to true or false; the default is true.

• profanityFilter is set to a value other than true or false.
• profanityFilter is used with a <Gather> speechModel that doesn't support it, such as numbers_and_commands, generic models set to Latin American Spanish, Vietnamese, or Swiss German (de-CH).

• Set profanityFilter to true or false in your <Gather> TwiML.
• If your speechModel doesn't support profanity filtering, remove profanityFilter or choose a supported speechModel.
• Review the <Gather> request and TwiML to confirm the value Twilio received.
