The Speech Technology and Research (STAR) Laboratory at
SRI is a world leader in speech technology, and is active in both
technology creation and technology transfer. Nuance Communications is
exploiting technology developed in the STAR Laboratory in over the
telephone applications. SRI's DECIPHER technology is capable of
recognizing natural, continuous speech without requiring the user to
train the system in advance (i.e., speaker-independent recognition).
The DECIPHER system exhibits strong performance in
Government-administered tests and can be distinguished from the few
other leading-edge speech recognition technologies by its detailed
modeling of variations in pronunciation and its robustness to
background noise and channel distortion. These features make the
DECIPHER system accurate in recognizing spontaneous speech of
different dialects and less dependent on the idiosyncracies of
different microphones and acoustic environments.
