13-Text to Speech

The .Net Framework 3.5 produce set of speech libraries for developing a Text-to-Speech. The System.Speech.Synthesis namespace provides a lot of classes for Text-to-Speech just like SpeechSynthesizer, VoiceInfo, InstalledVoice and many more.
Here’s the example on how to create a Text-to-Speech application:

1. Open the Visual Basic, select “File” on the menu, hit new and create a new project.
   
2. The New Project dialog will appear.
   
   Select “windows” in the project types, hit the “windows form application” in the templates and name your project “TextToSpeech” then hit “ok“.
3. Design the form this way. See it Below.
   
4. You need to add System.Speech for the reference of the program.
   
5. Double click the form and add this simple namespace for your imports.
   
   Visual Basic

   Imports System.Speech.Synthesis

   1	Imports System.Speech.Synthesis

6. double click the button to fire the click event handler of it. Do the following code to declare and instantiate an speech object.
   
   Visual Basic

   Dim speaks As New SpeechSynthesizer()

   1	Dim speaks As New SpeechSynthesizer()

7. Call the SpeakAsync  method of the object passing in a string containing the text we want to speak.
   
   Visual Basic

   speaks.Rate = 1 speaks.Volume = 100 speaks.Speak("Hi janobe")

   1 2 3

   speaks.Rate = 1 speaks.Volume = 100 speaks.Speak("Hi janobe")

8. The code in the view code will look like this.
   
   Visual Basic

   Imports System.Speech.Synthesis Public Class Form1Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim speaks As New SpeechSynthesizer()speaks.Rate = 1 speaks.Volume = 100 speaks.Speak("Hi janobe")End Sub End Class

   1 2 3 4 5 6

   Imports System.Speech.Synthesis Public Class Form1Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim speaks As New SpeechSynthesizer()speaks.Rate = 1 speaks.Volume = 100 speaks.Speak("Hi janobe")End Sub End Class
