Remarks
CompileConstraintsAsync must always be called before RecognizeAsync or RecognizeWithUIAsync, even if no constraints are specified in the Constraints property.
This method returns an error if:
- SpeechRecognizerState is not Idle or Paused.
- One or more constraints are specified when the recognition session is initialized, recognition is Paused, all constraints are removed, and recognition is resumed.
- No constraints are specified when the recognition session is initialized, recognition is Paused, constraints are added, and recognition is resumed.
To use web-service constraints, speech input and dictation support must be enabled in Settings by turning on the "Get to know me" option in the Settings -> Privacy -> Speech, inking, and typing page. See "Recognize speech input" in Speech recognition.
