// Deletes stored utterances. Amazon Lex stores the utterances that users send to
// your bot. Utterances are stored for 15 days for use with the GetUtterancesView
// operation, and then stored indefinitely for use in improving the ability of your
// bot to respond to user input. Use the DeleteUtterances operation to manually
// delete stored utterances for a specific user. When you use the DeleteUtterances
// operation, utterances stored for improving your bot's ability to respond to user
// input are deleted immediately. Utterances stored for use with the
// GetUtterancesView operation are deleted after 15 days. This operation requires
// permissions for the lex:DeleteUtterances action.
