C# System.speech.synthesis post processing

Question

Is there any way to apply post processing effects(change speed, pitch, volume) of the output from system.speech.synthesis in C#. To be more clear I am calling system.speech.synthesis.SpeechSynthisizer.Speak(String); and I want to edit the output. Thank you for your help.

Answer 1

you can change the volume and rate using the property Volume and Rate

        static void Main(string[] args)
        {
            SpeechSynthesizer synthesizer = new SpeechSynthesizer();
            synthesizer.Volume = 100;  // 0...100
            synthesizer.Rate = -2;     // -10...10

            // Synchronous
            synthesizer.Speak("Hello World");

            // Asynchronous
            synthesizer.SpeakAsync("Hello World");
        }
