 void AppendBreak();

public void AppendBreak();

member this.AppendBreak : unit -> unit

Public Sub AppendBreak ()

Examples

The following example builds a prompt containing two sentences separated by a break and speaks the prompt to the default audio device on the computer.

using System;
using System.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.SetOutputToDefaultAudioDevice();

        // 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();
        builder.AppendText(
          "Tonight's movie showings in theater B are at 5:15, 7:30, and 9:15.");

        // Speak the prompt.
        synth.Speak(builder);
      }

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

Remarks

This method does not specify a duration for the break. The SpeechSynthesizer will determine a duration value based on the linguistic context.

Parameters

Examples

The following example builds a prompt containing two sentences separated by a break and sends the output to a WAV file for playback.

using System;
using System.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\weather.wav");

        // 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(
          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(PromptBreak.Medium);
        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();
    }
  }
}

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.

Parameters

Examples

The following example builds a prompt containing two sentences separated by a break of 15,000,000 ticks (1.5 seconds), and speaks the prompt to the default audio device on the computer.

using System;
using System.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.SetOutputToDefaultAudioDevice();

        // 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.
        synth.Speak(builder);
      }

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

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.
