The lack of freely available state-of-the-art speech-to-text tools seriously hinders research in audio information processing technology. The Institute for Signal and Information Technology (ISIP) has recently been funded to develop a state-of-the-art large vocabulary conversational speech recognition system (LVCSR). This system is being placed into the public domain, and is freely available on the ISIP web site. The cornerstone of this system is some object-oriented digital signal processing software developed at Texas Instruments from 1989 - 1993.

In this talk, we will review several technologies currently under development at ISIP, including cross-word decoding in speech recognition and Switchboard resegmentation and transcription.
