| PromptBuilder..::..AppendBreak Method (PromptBreak) |
| PromptBuilder Class Example See Also Send Feedback |
Appends a break of the specified strength (duration) to the PromptBuilder object.
Namespace:
Microsoft.Speech.Synthesis
Assembly:
Microsoft.Speech (in Microsoft.Speech.dll)
Syntax
| Visual Basic (Declaration) |
|---|
Public Sub AppendBreak ( _ strength As PromptBreak _ ) |
| Visual Basic (Usage) |
|---|
Dim instance As PromptBuilder Dim strength As PromptBreak instance.AppendBreak(strength) |
| C# |
|---|
public void AppendBreak( PromptBreak strength ) |
Parameters
- strength
- Type: Microsoft.Speech.Synthesis..::..PromptBreak
Indicates the duration of the break.
Remarks
The values in the PromptBreak enumeration represent a range of separation intervals (pauses) between word boundaries. The speech synthesis engine determines the exact duration of the interval. When a break is requested, one of these values is passed to the text-to-speech (TTS) engine, which contains a mapping between these values and the corresponding millisecond break values.
Examples
The following example builds a prompt containing two sentences separated by a break and sends the output to a WAV file for playback.

// Create a SoundPlayer instance to play the output audio file.
System.Media.SoundPlayer m_SoundPlayer =
new System.Media.SoundPlayer(@"C:\test\weather.wav");
// Build a prompt with two sentences separated by a break.
PromptBuilder builder = new PromptBuilder(
