General Purpose Microcontroller Featuring Speech Recognition,
Speaker Verification, and Speech Synthesis.
GENERAL DESCRIPTION
The RSC-164i, from the Interactive Speech™ family of
products, is a low-cost microcontroller designed for use in
consumer electronics. The RSC-164i combines an 8-bit
microcontroller with high-quality speaker-independent
and speaker-dependent speech recognition, speaker
verification, and speech synthesis. Products can use one
or all of the RSC-164i features in a single application.
The RSC-164i 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. The RSC-164i is
similar to the RSC-164, but does not support a parallel
memory interface. All program, synthesis, recognition,
and verification code must fit in the on-chip ROM.
