PromptBuilder.AppendBreak Method (TimeSpan)


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

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

public void AppendBreak(
	TimeSpan duration


Type: System.TimeSpan

The time in ticks, where one tick equals 100 nanoseconds.

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.

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. 

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

        // Speak the prompt.

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