The GlobalCommands sample illustrates how to use commands by adding Start Over and Cancel commands to the RecognizeSpeech sample application. When run, the application plays a greeting, followed by a message informing the caller that he or she can say "start over" or "cancel" at any time. If the caller says "cancel," the application acknowledges that the caller canceled the application and says goodbye. If the caller says "start over," the sample starts over with the welcome message. Otherwise, this sample is identical to the RecognizeSpeech sample application.

  • Use of the Command Handler within a speech application workflow
  • Use of CommandActivity activities to implement multiple commands
