SPEECH RECOGNITION CHIP

The RSC-364 is a complete speech recognition system-on-a-chip for consumer electronic products and telephony applications. The system uses Sensory Speech 5.0 technology and is designed to be highly accurate. With the RSC-364, a complete high-accuracy speech recognition system can be built for less than $5.

Sensory Speech 5.0 technology, as implemented in the RSC-364, includes new noise-immune algorithms, new speech technologies, and significantly-improved recognition accuracy. Current algorithms deliver accuracy rates of greater than 97% for speaker-independent recognition and greater than 99% for speaker-dependent recognition in various noise environments.

Sensory Speech 5.0 features Fast Digit Recognition, providing speaker-adaptive recognition for consecutive digit-dialing applications, where accuracy requirements per digit must be above 99.5%. Sensory's new 5.0 algorithms reduce response time to under 290 ms with a 32-word speaker-dependent vocabulary.

The RSC-364 provides a 4-MIPS microcontroller, audio preamplifier, A/D and D/A converters, watchdog timer, 64 KB of ROM, and 2.5 KB of RAM. The specially designed 8-bit microcontroller provides programming flexibility while supporting a complete suite of speech and audio technologies including speech recognition, speech and music synthesis, speaker verification, and audio record and playback.The RSC-364 permits on-chip storage of speaker- dependent or speaker-independent vocabularies.

The device sells for less than $5 in quantities of 100,000.
