General Description
The RSC-464 is the newest member of Sensory’s
RSC-4x Family of microcontrollers with on-chip
speech I/O capabilities. The RSC-464 has many
features of the RSC-4128, but reduced in cost by
integrating less memory. The RSC-464 is designed to
bring high performance speech I/O features to cost
sensitive embedded and consumer products. Based
on an 8-bit microcontroller, the RSC-464 integrates
speech-optimized digital and analog processing
blocks into a single chip solution capable of accurate
speech recognition; high quality, low data-rate
compressed speech; and advanced music. Products
can use one or all features in a single application.
The RSC-464 operates in tandem with the radically
new FluentChip technology, offering the best
speech recognition technologies in the industry.
FluentChip includes Hidden Markov Model-Neural
Net hybrid speech recognition. Accuracy in all kinds
of noise is dramatically improved. New Speaker
Verification technology is perfect for voice password
security applications that must work in noisy
environments. New high quality compressed speech
technology reduces data rates by 5 times. New 8-
voice MIDI-compatible music includes drum tracks,

instruments
Simultaneous music and speech rounds out the
FluentChip technology.
FluentChip technology tools also support the
revolutionary
capability
independent recognition sets by simply typing in the
desired recognition vocabulary! A few keystrokes
creates a recognition set in seconds without the wait
or cost of recording sessions to train the recognizer,
speeding time to sales.
The Audio Wakeup feature listens while the RSC-464
is in power down mode. When an audio event such
as a clap or whistle occurs, Audio Wakeup will
wakeup the RSC-464 for speech or application tasks.
Audio Wakeup is perfect for battery applications that
require continuous listening and long battery life.
The RSC-464 provides further on-chip integration of
features. A complete speech I/O application can be
built with as few additional parts as a clock crystal,
speaker, microphone, and few resistors and
capacitors.

Moreover, the RSC-464 provides an unprecedented
level of cost effective system-on-chip (SOC)
integration, enabling many applications that require
DSP and/or audio processing. The RSC-464 may be
used as a general-purpose mixed signal processor
platform for custom algorithms, technologies and
applications.
