Speech Recognition Microcontroller
GENERAL DESCRIPTION
The RSC-300/364, from the Interactive Speech™ family
of products, is an 8-bit microcontroller designed
specifically for speech applications in consumer
electronic products. The RSC-300/364 is a single chip
solution that combines the flexibility of a microcontroller
with advanced speech technology, including high-quality
speech recognition, speech and music synthesis, speaker
verification, and voice record and playback. Products
can use one or all of the RSC-300/364 features in a single
application.
The RSC-300/364 supports Sensory Speech™ 5.0, the
latest speech recognition technology from Sensory, which
includes a number of new techniques that significantly
improve recognition performance over previous versions.
Using a sophisticated neural network technology, on-chip
speech recognition algorithms reach an accuracy of
greater than 97% for speaker-independent recognition
and greater than 99% for speaker-dependent recognition.
In addition to the improved recognition performance, the
RSC-300/364 provides further on-chip integration of
features, including a preamplifier, multiplier, watchdog
timer, and 2.5 Kbytes of RAM. A complete system may
be built with few additional parts other than a battery,
speaker, microphone, and a few resistors and capacitors.
The RSC-300 is designed for ROM-less for applications
that need more ROM space and consequently use off-chip
memory.
