Question

in my asp.net project, I code below for a text to speech function.
in my page’s c# file.

 byte[] SpeakText(string text) 
        { 
            using (SpeechSynthesizer s = new SpeechSynthesizer()) 
            { 
                using (MemoryStream ms = new MemoryStream()) 
                { 
                    s.SetOutputToWaveStream(ms); 
                    s.Speak(text); 
                    return ms.GetBuffer(); 
                } 
            } 
        }
protected void Button1_Click(object sender, EventArgs e)
        {


            if (TextBox1.Text != "")
            {
                Response.Write(SpeakText(TextBox1.Text));

            }

        }

but not hear the audio while run it.

How to solve the problem?

Answer 1

Try setting the response content type:

Response.ContentType = "audio/wav";

Also don’t use Response.Write as it expects encoded characters. You need to write binary to avoid getting corrupt data:

Response.Clear();
Response.ContentType = "audio/wav";
Response.BinaryWrite(SpeakText(TextBox1.Text));
Response.End();
