My C# application needs to covert text to wav file and inject it into a Skype call. The code that creates the wav file is below. The problem is that the file has 22kHz sample rate and Skype accepts only 16kHz.
Is there any way to adjust this setting?
using (System.IO.FileStream stream = System.IO.File.Create("message.wav"))
{
System.Speech.Synthesis.SpeechSynthesizer speechEngine = new System.Speech.Synthesis.SpeechSynthesizer();
speechEngine.SetOutputToWaveStream(stream);
speechEngine.Speak(number);
stream.Flush();
}
