RecognizedAudio.AudioPosition Property
Gets the location in the input audio stream for the start of the recognized audio.
Namespace: Microsoft.Speech.Recognition
Assembly: Microsoft.Speech (in Microsoft.Speech.dll)
Syntax
'Declaration
Public ReadOnly Property AudioPosition As TimeSpan
Get
'Usage
Dim instance As RecognizedAudio
Dim value As TimeSpan
value = instance.AudioPosition
public TimeSpan AudioPosition { get; }
Property Value
Type: System.TimeSpan
The location in the input audio stream for the start of the recognized audio.
Remarks
This property references the position at the beginning of the recognized phrase in the input device's generated audio stream. By contrast, the RecognizerAudioPosition property references the recognizer's position within its audio input. These positions can be different. For more information, see Use Speech Recognition Events (Microsoft.Speech).
The StartTime property gets the system time at the start of the recognition operation.
Examples
The following example handles the SpeechRecognitionEngine.SpeechRecognized or Grammar.SpeechRecognized event and outputs to the console information about the recognized audio that is associated with the recognition result.
// Handle the SpeechRecognized event.
void SpeechRecognizedHandler(object sender, SpeechRecognizedEventArgs e)
{
if (e.Result == null) return;
RecognitionResult result = e.Result;
Console.WriteLine("Grammar({0}): {1}",
result.Grammar.Name, result.Text);
if (e.Result.Audio != null)
{
RecognizedAudio audio = e.Result.Audio;
Console.WriteLine(" start time: {0}", audio.StartTime);
Console.WriteLine(" encoding format: {0}", audio.Format.EncodingFormat);
Console.WriteLine(" position: {0}, duration: {1}",
audio.AudioPosition, audio.Duration);
}
// Add event handler code here.
