RSC-4128

The RSC-4128 represents Sensory's next generation speech and analog I/O mixed signal processor. The RSC-4128 is designed to bring advanced speech I/O features to cost sensitive embedded and consumer products. Based on an 8-bit microcontroller, the RSC- 4128 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-4128 supports Sensory Speech™ 7 technology, which includes advanced speech algorithms that add features and improve performance. Capable of running both new HMM and enhanced neural network technologies, 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, effectively increasing instruments beyond 8. Simultaneous music and speech rounds out the Sensory Speech™ 7 technology.

capability of creating speaker 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.

A new and unique Audio Wakeup feature listens while the RSC-4128 is in power down mode. When an audio event such as a clap or whistle occurs, Audio Wakeup will wakeup the RSC-4128 for speech or application tasks. Audio Wakeup is perfect for battery applications that require continuous listening and long battery life.

In addition to improved recognition performance, the RSC-4128 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.
