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.
