“Sphinx 2 was released as Open Source in hopes that the
release will stimulate the creation of speech-using tools and
applications “and to advance the state of the art both directly in
speech recognition, as well as in related areas including dialog
systems and speech synthesis,” according to its
developers.”
“In summary, the CMU Sphinx Group is releasing a set of
reasonably mature, world-class speech components that provide a
basic level of technology to anyone interested in creating
speech-using applications without the once-prohibitive initial
investment cost in research and development,” the developers
continue. “The same components are open to peer review by all
researchers in the field, and are used for linguistic research as
well.”
“The licensing terms for the Sphinx engines and tools are
derived from BSD [Berkely Software Design], and based, in
particular, upon the license for the Apache Web server. There is no
restriction against commercial use or redistribution.”
