Yamabay's Text to MP3 on Windows Project

Background:

Microsoft's Speach Server provides the foundation technology to convert text file to  WAV file format. WAV is clear, but not as compact as MP3. Our goal is to convert text file to MP3 by using Microsoft Speach Server SAPI 5.1 and Open Source Lame Project.

Microsoft's SAPI5.1 + LAME
