Abstract
In this paper, we first review Sphinx-II, a large-vocabulary speaker-independent continuous
speech recognition system developed at CMU. We summarize techniques that helped Sphinx-II
achieve the state-of-the-art large-vocabulary continuous speech recognition performance. We
then review Whisper, a system we developed here at Microsoft Research. We focus on
recognition accuracy, efficiency and usability issues, which are critical to the success of
commercial speech applications. Whisper has significantly improved Sphinx-II’s performance in
these three areas.
