Windows.Media.SpeechRecognition Namespace

Enables speech recognition for command and control within Windows Runtime app.

Classes

SpeechContinuousRecognitionCompletedEventArgs	Contains continuous recognition event data for the SpeechContinuousRecognitionSession.Completed event.
SpeechContinuousRecognitionResultGeneratedEventArgs	Contains event data for the SpeechContinuousRecognitionSession.ResultGenerated event.
SpeechContinuousRecognitionSession	Manages speech input for free-form dictation, or an arbitrary sequence of words or phrases that are defined in a local grammar file constraint.
SpeechRecognitionCompilationResult	The result of compiling the constraints set for a SpeechRecognizer object.
SpeechRecognitionGrammarFileConstraint	A custom grammar constraint based on a list of words or phrases (defined in a Speech Recognition Grammar Specification (SRGS) file) that can be recognized by the SpeechRecognizer object. Note Speech recognition using a custom constraint is performed on the device.
SpeechRecognitionHypothesis	A recognition result fragment returned by the speech recognizer during an ongoing dictation session. The result fragment is useful for demonstrating that speech recognition is processing input during a lengthy dictation session.
SpeechRecognitionHypothesisGeneratedEventArgs	Contains event data for the SpeechRecognizer.HypothesisGenerated event.
SpeechRecognitionListConstraint	A custom grammar constraint based on a list of words or phrases that can be recognized by the SpeechRecognizer object. When initialized, this object is added to the Constraints collection. Note Speech recognition using a custom constraint is performed on the device.
SpeechRecognitionQualityDegradingEventArgs	Provides data for the SpeechRecognitionQualityDegradingEvent event.
SpeechRecognitionResult	The result of a speech recognition session.
SpeechRecognitionSemanticInterpretation	Represents the semantic properties of a recognized phrase in a Speech Recognition Grammar Specification (SRGS) grammar.
SpeechRecognitionTopicConstraint	A pre-defined grammar constraint (specifed by SpeechRecognitionScenario) provided through a web service.
SpeechRecognitionVoiceCommandDefinitionConstraint	A constraint for a SpeechRecognizer object based on a Voice Command Definition file.
SpeechRecognizer	Enables speech recognition with either a default or a custom graphical user interface (GUI).
SpeechRecognizerStateChangedEventArgs	Provides data for the SpeechRecognizer.StateChangedEvent event.
SpeechRecognizerTimeouts	The timespan that a speech recognizer ignores silence or unrecognizable sounds (babble) and continues listening for speech input.
SpeechRecognizerUIOptions	Specifies the UI settings for the SpeechRecognizer.RecognizeWithUIAsync method.
VoiceCommandManager	Note VoiceCommandManager may be altered or unavailable for releases after Windows Phone 8.1. Instead, use Windows.ApplicationModel.VoiceCommands.VoiceCommandDefinitionManager. A static class that enables installing command sets from a Voice Command Definition (VCD) file, and accessing the installed command sets.
VoiceCommandSet	Note VoiceCommandSet may be altered or unavailable for releases after Windows Phone 8.1. Instead, use Windows.ApplicationModel.VoiceCommands.VoiceCommandDefinition. Enables operations on a specific installed command set.

Interfaces

ISpeechRecognitionConstraint

Represents a constraint for a SpeechRecognizer object.

Enums

SpeechContinuousRecognitionMode	Specifies the behavior of the speech recognizer during a continuous recognition session.
SpeechRecognitionAudioProblem	Specifies the type of audio problem detected.
SpeechRecognitionConfidence	Specifies confidence levels that indicate how accurately a spoken phrase was matched to a phrase in an active constraint.
SpeechRecognitionConstraintProbability	Specifies the weighted value of a constraint for speech recognition.
SpeechRecognitionConstraintType	Specifies the grammar definition constraint used for speech recognition.
SpeechRecognitionResultStatus	Specifies the possible result states of a speech recognition session or from the compiling of grammar constraints.
SpeechRecognitionScenario	Specifies the scenario used to optimize speech recognition for a web-service constraint (created through a SpeechRecognitionTopicConstraint object).
SpeechRecognizerState	Specifies the state of the speech recognizer.

Remarks

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.
