Convert audio to text

Question

I just want to know if there is any build in libraries or external libraries in Java or C# that allow me to take an audio file and parse it and extract the text from it.

Answer 1

You can use SoX (the Swiss Army knife of sound processing programs) to convert audio file to text file with numeric values corresponding to sound frequency/volume.

I have done it for a previous project but don't know the exact command options.

Here is a link to the project: http://sox.sourceforge.net/Main/HomePage
