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();
}
}
