In my windows service .NET 4.0 application I use SpeechSynthesizer to speech some text. In Windows XP works great, but on Windows 7 it doesn't play anything. Why?
(Microsoft Server Speech Platform Runtime 11.0 + Speech Text To Speech Voice Lucia)
many thanks, Riccardo
Please try using System.Speech and System.Speech.Synthesize instead of Microsoft.Speech. I have developed a tool to recoganize the voice using System.Speech which is working good for me in Windows Vista, Windows 7. Please do a check whether your windows speech system is working or not.

To use "it-IT" culture
Private Sub CreateSpeechRecoginationEngine(culture As String)
Dim _culture As CultureInfo
For Each recognizer In SpeechRecognitionEngine.InstalledRecognizers
If recognizer.Culture.Name.Equals(culture) Then
_culture = recognizer.Culture
Exit For
End If
Next
If _culture Is Nothing Then _culture = SpeechRecognitionEngine.InstalledRecognizers()(0).Culture
SpeechRecognitionEngine speechRecoginationEngine = New SpeechRecognitionEngine(_culture)
End Sub
