Namespace:
Microsoft.Speech.Synthesis
Assembly:
Microsoft.Speech (in Microsoft.Speech.dll)
Syntax
| Visual Basic (Declaration) |
|---|
Public Sub SetOutputToWaveStream ( _ audioDestination As Stream _ ) |
| Visual Basic (Usage) |
|---|
Dim instance As SpeechSynthesizer Dim audioDestination As Stream instance.SetOutputToWaveStream(audioDestination) |
| C# |

public void SetOutputToWaveStream( Stream audioDestination ) |
Parameters
- audioDestination
- Type: System.IO..::..Stream
The stream to which to append synthesis output.
Remarks
To release the SpeechSynthesizer's reference to the stream, reconfigure the synthesizer's output, for example, by calling SetOutputToNull.

streamAudio.Position = 0;
m_SoundPlayer.Stream = streamAudio;
