RecognizeUserInput (Communications Workflow Sample)

  • Article

This sample speech workflow application demonstrates how to use grammars to recognize both speech and dual-tone multi-frequency (DTMF) inputs. The user is asked to enter their PIN, and the user can respond by speaking the PIN or entering it using a keypad. The application recognizes the input and repeats it back to the user.

  • Use the SpeechQuestionAnswerActivity.DtmfGrammars and SpeechQuestionAnswerActivity.Grammars properties.

  • Use grammars with the SpeechHelpCommandActivity and SpeechRepeatCommandActivity activity.

Prerequisites
