I am having an issue creating a working wav file from a web server using speechlib. I have tried multiple ways. I have tried creating a web service that creates the wav file as well as creating the wav file directly in the code behind of the web from.

The following code creates the file but it is 0 bytes and will not play.

C#

try
       {

           SpVoice voice = new SpVoice();

           SpFileStream fileStream = new SpFileStream();

           fileStream.Open(speechWavPath, SpeechStreamFileMode.SSFMCreateForWrite, false);

           voice.AudioOutputStream = fileStream;

           voice.Speak(currentWord, SpeechVoiceSpeakFlags.SVSFDefault);

           fileStream.Close();
       }
       catch
       {
           throw;
       }

I have also created a web service and it did the same thing. please help

Why would you want to do this in a web server application? Considering there's usually no audio in a web server and nobody around to listen to it, why would you want the server speaking anything at all?

I want to be able to take the text and convert to wav file to be played back on the clients computer. the server it self will not speak anything.

Web applications, by default, don't have write permissions to their folders. This is for security reasons. You need to give the account running your application NTFS permissions to write to the folder that you're trying to save the .WAV file to.

The the directory that it is pointed to is on the same machine and the directory has everyone access.

It also is able to create the file but it is a 0 byte file.

In that case, I have no idea why it's not working. I've never had any purpose to use the speech API's.

Well, unless "currentWord" doesn't contain a string. If that variable is empty or null that would probably make a 0 byte file.

i works on my box. i will double check to make sure it is getting the currentword.

I checked the currentword does contain a string. I dug some more and found no matter where I point the directory of the wav file it will not write it. I have tried the C:temp folder, the public folder, a different hard drive on the same box. nothing will write. the only time I get anything is when I use the web service (which is part of the same project). that is when it will create a 0 byte wav. but it will not open.

In that case I have no idea what's causing it.
