HandleRecognitionErrors (Communications Workflow Sample)

  • Article

This sample speech workflow application demonstrates how to use event activities to handle error scenarios, such as no input from the user or the inability to recognize the user's input. While the SpeechQuestionAnswerActivity activity includes functionality to handle these scenarios to some degree, with event activities, specific responses can be implemented when an error situation occurs a specific number of times in a row.

  • Use two speech event activities:ConsecutiveNoRecognitionsSpeechEventActivity and ConsecutiveSilencesSpeechEventActivity.

  • Use the SpeechPrompts.EscalatedSilencePrompt and SpeechPrompts.EscalatedNoRecognitionPrompt property.

  • Use the ResourceManager class to provide culture-specific prompt text.

Prerequisites
