Introducing the FireCracker!
Based on Analog Devices popular Blackfin embedded processor, Silica has developed the FireCracker Development and Reference Design Platform for audio and video applications. FireCracker is a unique concept of a hybrid between a development board and a reference design that enables design engineers to bring embedded computing solutions from concept to production in record time.

FreeTTS 1.1.1 - A speech synthesizer written entirely in Java
It is based upon Flite 1.1: a small run-time speech synthesis engine developed at Carnegie Mellon University. Flite is derived from the Festival Speech Synthesis System from the University of Edinburgh and the FestVox project from Carnegie Mellon University.

GSM 06.10 lossy speech compression
The low­level speech compression algorithm of the GSM suite is called GSM 06.10 RPE­LTP (Regular­Pulse Excitation Long­Term Predictor). My colleague Dr. Carsten Bormann and I have implemented a GSM 06.10 RPE­LTP coder and decoder in C. Its source code is freely available, and we encourage you to use it, play with it, and invent new real­time media protocols and algorithms.

IT++
IT++ is a C++ library of mathematical, signal processing, speech processing, and communications classes and functions. It has been developed by researchers in these areas. The kernel of the package are templated vector and matrix classes and lots of functions for vectors and matrices. As such the kernel is similar to the Matlab functions.
