recognition accuracy (see the article on Speech Recognition for descriptions of these techniques). Sphinx 4 Sphinx 4 is a complete rewrite of the Sphinx engine with the goal of providing a more flexible framework for research in speech recognition, written entirely in the Java programming language. Sun Microsystems supported the development of Sphinx 4 and contributed software engineering expertise to the project. Participants included individuals at MERL, MIT and CMU. (Currently supported languages are C, C++, C#, Python, Ruby, Java, and JavaScript.) Current development goals include: developing a new (acoustic model) trainer implementing speaker adaptation (e.g. MLLR) improving configuration management creating a graph-based UI for graphical system design PocketSphinx A version of Sphinx that can be used in embedded systems (e.g., based on an ARM processor). PocketSphinx is under active development and incorporates features such as fixed-point arithmetic and efficient algorithms for GMM computation.
