PromptBuilder.AppendBreak Method (TimeSpan)

Appends a break of the specified duration to the PromptBuilder object.

Namespace:  Microsoft.Speech.Synthesis
Assembly:  Microsoft.Speech (in Microsoft.Speech.dll)

Syntax

'Declaration
Public Sub AppendBreak ( _
    duration As TimeSpan _
)
'Usage
Dim instance As PromptBuilder
Dim duration As TimeSpan

instance.AppendBreak(duration)
public void AppendBreak(
    TimeSpan duration
)

Parameters

  • duration
    Type: System.TimeSpan
    The time in ticks, where one tick equals 100 nanoseconds.

Remarks

A break can be used to control pauses or other prosodic boundaries between words. A break is optional. If a break is not present, the synthesizer determines the break between words depending on the linguistic context.

Examples

The following example builds a prompt containing two sentences separated by a break of 15,000,000 ticks (1.5 seconds), and sends the output to a WAV file for playback.

using System;
using Microsoft.Speech.Synthesis;

namespace SampleSynthesis
{
  class Program
  {
    static void Main(string[] args)
    {

      // Initialize a new instance of the SpeechSynthesizer.
      using (SpeechSynthesizer synth = new SpeechSynthesizer())
      {

        // Configure the audio output. 
        synth.SetOutputToWaveFile(@"C:\test\ShowTimes.wav");

        // Create a SoundPlayer instance to play the output audio file.
        System.Media.SoundPlayer m_SoundPlayer =
          new System.Media.SoundPlayer(@"C:\test\ShowTimes.wav");

        // Build a prompt with two sentences separated by a break.
        PromptBuilder builder = new PromptBuilder(
          new System.Globalization.CultureInfo("en-US"));
        builder.AppendText(
          "Tonight's movie showings in theater A are at 5:45, 7:15, and 8:45");
        builder.AppendBreak(new TimeSpan(15000000));
        builder.AppendText(
          "Tonight's movie showings in theater B are at 5:15, 7:15, and 9:15");

        // Speak the prompt and play back the output file.
        synth.Speak(builder);
        m_SoundPlayer.Play();
      }

      Console.WriteLine();
      Console.WriteLine("Press any key to exit...");
      Console.ReadKey();
    }
  }
}
