SpeechRecognitionEngine.EndSilenceTimeoutAmbiguous Property


Gets or sets the interval of silence that the SpeechRecognitionEngine will accept at the end of ambiguous input before finalizing a recognition operation.

 property TimeSpan EndSilenceTimeoutAmbiguous { TimeSpan get(); void set(TimeSpan value); };
public TimeSpan EndSilenceTimeoutAmbiguous { get; set; }
member this.EndSilenceTimeoutAmbiguous : TimeSpan with get, set
Public Property EndSilenceTimeoutAmbiguous As TimeSpan

Property Value


The duration of the interval of silence.


This property is set to less than 0 seconds or greater than 10 seconds.


The speech recognizer uses this timeout interval when the recognition input is ambiguous. For example, for a speech recognition grammar that supports recognition of either "new game please" or "new game", "new game please" is an unambiguous input, and "new game" is an ambiguous input.

This property determines how long the speech recognition engine will wait for additional input before finalizing a recognition operation. The timeout interval can be from 0 seconds to 10 seconds, inclusive. The default is 500 milliseconds.

To set the timeout interval for unambiguous input, use the EndSilenceTimeout property.
