Fast, Accurate, Flexible Open Source Speech Recognition

Since being released as open source code in 1999, CMU Sphinx provides a platform for building speech recognition applications. It's used in desktop control software, telephony platforms, intelligent houses, computer-assisted language learning tools, information retrieval and mobile applications. Traditionally, CMUSphinx provides support for low-resource and underdeveloped languages.
