Sphinx is the general term to describe a group of speech recognition systems developed at Carnegie Mellon University. These includes a series of speech recognizers (Sphinx 2 - 4) and an acoustic model trainer (SphinxTrain). In 2000, the Sphinx group at Carnegie Mellon committed to open source several speech recognizer components, including Sphinx 2 and later Sphinx 3 (in 2001). More generally CMU Sphinx refers to a group of open source systems related to speech recognition. For the most part, the speech decoders are perhaps the best known, since they come with acoustic models and sample applications. The available resources include in addition software for acoustic model training, language model compilation and a public-domain pronunciation dictionary, cmudict (see the project home page for details). CMU Sphinx is perhaps the only open source, large vocabulary, continuous speech recognition project that consistently releases its work under the liberal BSD-license. Sphinx encompasses a number of distinct software systems, described below.   [edit]  Less
