public TimeSpan TrailingSilenceTrimmedLength { get; set; }
Property Value
The amount of trailing silence, in milliseconds, that should be left after trimming.
Exceptions
Exception type | Condition |
---|---|
ArgumentOutOfRangeException | An attempt is made to set TrailingSilenceTrimmedLength to a value less than TimeSpan.Zero. |
Remarks
TimeSpan.Infinite means no trimming. Trimming never removes audio that occurs before the end of speech.
Example
The following code example shows the creation of a RecordAudioActivity instance, recordAudio. After recordAudio is created, a number of its properties are set. The highlighted line of code shows the TrailingSilenceTrimmedLength property being set to 0.5 second.
this.recordAudio = new Microsoft.SpeechServer.Dialog.RecordAudioActivity();
this.recordAudio.AudioEncoding = Microsoft.SpeechServer.Codec.Pcm8kHz16bit;
this.recordAudio.CanBargeIn = false;
this.recordAudio.EndSilenceTimeout = System.TimeSpan.Parse("00:00:01.5000000");
this.recordAudio.InitialSilenceTimeout = System.TimeSpan.Parse("00:00:01.5000000");
this.recordAudio.LeadingSilenceTrimmedLength = System.TimeSpan.Parse("00:00:00.5000000");
this.recordAudio.Name = "RecordAudio";
this.recordAudio.PlayBeep = true;
this.recordAudio.TerminationDigits = Microsoft.SpeechServer.RecordTerminationDigits.None;
this.recordAudio.TrailingSilenceTrimmedLength = System.TimeSpan.Parse("00:00:00.5000000");
recordAudio.MainPrompt.SetText(GetPromptResource("recordAudio_MainPrompt"));
this.Activities.Add(this.recordAudio);
