Speech synthesis is the process of turning text into audio. In WPF is a very simple thing. The first thing you have to do is add a reference to System.Speech.dll to your project. The code is very simple and it explains by itself, so here you have code…

<Window x:Class=”SpeechTesting.Window1″
xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation”
xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml”
Title=”Speech Test” Height=”100″ Width=”300″>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=”5*”/>
<ColumnDefinition Width=”*”/>
</Grid.ColumnDefinitions>
<TextBox x:Name=”tb” Grid.Column=”0″/>
<Button Content=”Speech” Grid.Column=”1″ Click=”Button_Click”/>
</Grid>
</Window>

public partial class Window1 : Window

SpeechSynthesizer ss = new SpeechSynthesizer();

}

private void Button_Click(object sender, RoutedEventArgs e)
{
ss.Speak(tb.Text);
}
}
}
