The Defense Advanced Research Projects Agency (DARPA) sponsored a project known as Novel Approaches which is a component of the Effective Affordable Reusable Speech-to-text (EARS) program. The main goal for this effort was to push the spectral envelope away from being the sole source of acoustic information incorporated by the statistical models of modern speech recognition systems (SRSs). To date, much of the effort has gone towards the design of new features and experimentation with their incorporation in a modern speech-to-text system. The new features have already provided significant improvements in such a system in the 2004 NIST evaluation of recognizers of conversational telephone speech.
