General Purpose Microcontroller Featuring Speech Recognition, Speech &
Music Synthesis, Speaker Verification and Audio Record/Playback
GENERAL DESCRIPTION
The RSC-164, from the Interactive Speech™ family of
products, is a low-cost microcontroller designed for use
in consumer electronics. The RSC-164 combines an 8-bit
microcontroller with high-quality speaker-independent
and speaker-dependent speech recognition, speech
synthesis, speaker verification, four-voice music
synthesis, and voice record and playback. Products can
use one or all of the RSC-164 features in a single
application.
The RSC-164 employs a sophisticated neural network
that learns to classify sound data. On-chip speech
recognition algorithms reach an accuracy of greater than
96% for speaker-independent recognition and greater
than 99% for speaker-dependent recognition. Sensory’s
neural network approach (patent pending) eliminates the
need for expensive signal processing or extensive RAM
storage.
The highly-integrated nature of the chip reduces external
parts count. A complete system may be built with few
additional parts other than a battery, speaker,
microphone, and audio input support circuitry. Low
power requirements make the RSC-164 an ideal solution
for battery-powered and hand-held devices.
