Convert text (string) to audio file and save File in Folder (Directory) using C# and VB.Net in ASP.Net

Hi dilipsharm,

Check this example. Now please take its reference and correct your code.

Add the reference of System.Speech dll in your project.

There are multiple options such as saving to an existing stream.

If you want to create a new WAV file, you can use the SetOutputToWaveFile method.

Code

C#

System.Speech.Synthesis.SpeechSynthesizer sp = new System.Speech.Synthesis.SpeechSynthesizer();
sp.SpeakAsync("Welcome to ASPSnippets.");
sp.SetOutputToWaveFile(Server.MapPath("Test.wav"));

VB.Net

Dim sp As System.Speech.Synthesis.SpeechSynthesizer = New System.Speech.Synthesis.SpeechSynthesizer()
sp.SpeakAsync("Welcome to ASPSnippets.")
sp.SetOutputToWaveFile(Server.MapPath("Test.wav"))
