Sensory’s RSC4128 and RSC464 Speech Recognition and Synthesis Microcontrollers

The Sensory’s RSC-4x Speech Recognition and Synthesis 8-bit microcontrollers is designed to bring advanced audio features to cost sensitive embedded-systems and low cost consumer products, such as toys for children. The RSC-4x family integrates speech-optimized digital and analog processing blocks into a single chip solution capable of accurate speech recognition as well as high quality, low data-rate compressed speech.

The RSC-4x family supports FluentChipâ„¢ technology, which includes advanced algorithms that add features and increase accuracy. In addition to the improved recognition performance, the RSC-4x family provides further on-chip integration of features, including:

• a microphone preamplifier,
• twin-DMA units,
• vector accelerator,
• hardware multiplier,
• 3 timers,
• and 4.8 Kbytes of RAM.

A complete system may be built with minimal additional parts other than a battery, speaker, microphone, and a few resistors and capacitors.

Two ROM configurations of the RSC-4x speech recognition microcontrollers:

• RSC-4128 (128kb ROM), recommended for all applications. 
• RSC-464 (64kb ROM), recommended for applications that require less duration of speech or smaller command sets (cost savings)

Developmen Tools

Sensory has partnered with Phyton to create development tools for these RSC-4x speech recognition and synthesis microcontrollers  This suite of development tools offers power and flexibility for creating fast, risk-free embedded speech applications quickly on the RSC-4x platform.

All chip programming is done under the Project-SE Phyton IDE, and requires the FluentChipâ„¢ libraries and QuickSynthesisâ„¢ 4 tools. The Phyton IDE, FC libraries and QS tools are provided free of charge for downloading after submitting the registration. Note that Phyton’s C Compiler and Sensory’s Quick T2SIâ„¢ software are not free and must be licensed separately. Phyton Tools must be purchased from Phyton directly.
