Introduction

This code is an introduction on how to use the new System.Speech class in the .NET Framework v3.0 and v3.5. The sample source code includes an application and the source code is provided in all three .NET languages (VB, C++, C#). It is a simple Windows application and shows how to use text to speech and how to export the speech to a WAV file. The source code was written in Visual Studio 2008 using .NET 3.5.

The Code

Namespaces

First, we need to reference the System.Speech assembly from the application. From the Project menu, choose Add Reference. The from the .NET tab, highlight System.Speech and choose OK.
Then add a simple namespace import to your class file (the Form file).

Hide   Copy Code

// C#
using System.Speech.Synthesis;

Hide   Copy Code

// C++
using namespace System::Speech::Synthesis;

Hide   Copy Code

' VB
Imports System.Speech.Synthesis 

Declarations

Next, we need to declare and instantiate a speech object. The class isSystem.Speech.Synthesis.Speechsynthesizer. This one class has enough properties and methods to speak a string using the default language and voice of the OS. In Microsoft Windows Vista, the default voice is Microsoft Ana. For Windows XP, it's Microsoft Sam. You can install additional voices, but I'll leave that to another article.

Hide   Copy Code

// C#
SpeechSynthesizer speaker = new SpeechSynthesizer();

Hide   Copy Code

// C++
public: SpeechSynthesizer speaker;

Hide   Copy Code

' VB
Dim speaker as New SpeechSynthesizer()

Usage

Finally, we call the Speak or SpeakAsync method of the object passing in a string containing the text we want spoken.

Hide   Copy Code

// C#
speaker.Rate = 1;
speaker.Volume = 100;
speaker.Speak("Hello world.");

Hide   Copy Code

// C++
speaker.Rate = 1;
speaker.Volume = 100;
speaker.Speak("Hello world.");

Hide   Copy Code

' VB
speaker.Rate = 1
speaker.Volume = 100
speaker.Speak("Hello world".)

You can see from the image that I have also included settings for speaking rate and volume. The sample programs also include code for saving the spoken string to a WAV file. Then you can set your system's sounds to the WAV files you create and your computer will sound like Dr. Falkan's. Would you like to play a game?

Hide   Copy Code

// CS
speaker.SetOutputToWaveFile("c:\soundfile.wav");
speaker.Speak("Hellow world.");
speaker.SetOutputToDefaultAudioDevice();
//Must remember to reset out device or the next call to speak 
//will try to write to a file

Hide   Copy Code

// C++
speaker.SetOutputToWaveFile("c:\soundfile.wav");
speaker.Speak("Hellow world.");
speaker.SetOutputToDefaultAudioDevice();
//Must remember to reset out device or the next call to speak 
//will try to write to a file

Hide   Copy Code

' VB
speaker.SetOutputToWaveFile("c:\soundfile.wav")
speaker.Speak("Hellow world.")
speaker.SetOutputToDefaultAudioDevice()
'Must remember to reset out device or the next call to speak 
'will try to write to a file
