Examples
The following example creates a PromptBuilder object and appends text strings. The example uses the AppendText(String, PromptRate) method to specify a slow speaking rate for the string being added, which enumerates the contents of an order.
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\Hardware.wav");
// Create a SoundPlayer instance to play the output audio file.
System.Media.SoundPlayer m_SoundPlayer =
new System.Media.SoundPlayer(@"C:\test\Hardware.wav");
// Create a PromptBuilder object and add content.
PromptBuilder speakRate = new PromptBuilder();
speakRate.AppendText("Your order for");
speakRate.AppendText("one kitchen sink and one faucet", PromptRate.Slow);
speakRate.AppendText("has been confirmed.");
// Speak the prompt and play back the output file.
synth.Speak(speakRate);
m_SoundPlayer.Play();
}
Console.WriteLine();
Console.WriteLine("Press any key to exit...");
Console.ReadKey();
}
}
