FreeTTS is a speech synthesis system written entirely in the Java programming language. It is based upon Flite, a small, fast, run-time speech synthesis engine, which in turn is based upon University of Edinburgh s Festival Speech Synthesis System and Carnegie Mellon University s FestVox project.

This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).
