How to use the Speech Synthesizer in WPF

Microsoft provides a new speech API (SAPI) for Windows Vista and later. It allows developers to build speech enabled applications. Simply add a reference to System.Speech and include the following code to your project.

 
using System.Speech.Synthesis;
 
SpeechSynthesizer synthesizer = new SpeechSynthesizer(); 
synthesizer.Volume = 50;  // 0...100
synthesizer.Rate = 3;     // -10...10
 
// Synchronous
synthesizer.Speak("Welcome to the WPF Tutorial.");
 
// Asynchronous
synthesizer.SpeakAsync("Welcome to the WPF Tutorial.");

Speak is used for one after one speech , but speakasync will do asyncronously , means if u write speakasync method twice two speech will done simultaniusly

Nouf, this is only a partial explanation of speakasync. This method means that once the line of code is executed speach will start and the execution of the code continues. That means the application is still able to respond.
