Sensory's RSC-4x Sets New Standard for Single Chip Speech Recognition.Business Editors/High-Tech Writers SANTA CLARA, Calif.--(BUSINESS WIRE)--April 29, 2002 Sensory, Inc., the leader in embedded speech technologies, announced the introduction of the RSC-4x, a family of highly integrated speech recognition and synthesis processors targeted at consumer, handheld and automotive products. "As our fourth generation processor, the RSC-4x builds on our industry leading RSC-364 by offering higher accuracy and more features while still hitting aggressive system cost targets," said Erik Soule, director of marketing for Sensory. "This family of chips combines everything our customers have been requesting, including faster recognition response time, improved noise robustness, low-data rate speech synthesis, and more product control features." Powerful Recognition, Synthesis and Control The RSC-4x family has been optimized to work in concert with Sensory Speech 7 (SS7) technology code, a software suite that enables advanced features such as multi-word speaker-independent wordspotting, speech and music synthesis, and up to 100 speaker-dependent words in an active vocabulary. SS7 takes advantage of powerful new on-chip hardware blocks, including a vector processor with twin-DMA units, 16-bit ADC (1) See A/D converter. (2) (Apple Display Connector) A peripheral connector from Apple that combines digital video display, USB and power in one cable. , 10-bit DAC See D/A converter and discretionary access control. DAC - Digital to Analog Converter , main oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air PLL PLL - phase-locked loop , microphone preamplifier Preamplifier A voltage amplifier suitable for operation with a low-level input signal. It is intended to be connected to another amplifier with a higher input level. with AGC AGC Automatic Gain Control AGC Automotive Glass Cartridge (fuse) AGC Associated General Contractors AGC Associated General Contractors of America AGC Atypical Glandular Cells AGC Attorney-General's Chambers , low-EMI PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a speaker driver, 2 independent timers plus separate watchdog, 4 comparator inputs, 2 low-power modes and 24 I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output lines. One Chip, One Supplier The RSC-4x enables exciting hands-free applications at very low system costs, with little more than a low cost microphone, speaker, and crystal required for a complete application. The chip also supports Sensory's SX synthesis -- a new high quality, low data-rate proprietary LPC (language) LPC - A variant of C designed ca 1988 to program LP MUDs. technology that enables products to contain over five minutes of compressed audio, multiple speaker-independent and speaker-dependent vocabularies, speaker verification, and all application code -- all on a single IC. And unlike many competing solutions, all technology software is included in the chip price, avoiding potential compatibility problems and negotiations with multiple vendors. To speed time to market, an all-new tool chain is available (including in-circuit emulators, a C-compiler, and low cost evaluation toolkits). Price and Availability The RSC-4x family consists of the RSC-4000, RSC-4128, and RSC-4256. The RSC-4000 is a ROM-less version with address and data buses, while the other versions contain 128 and 256 Kbytes of mask-programmable ROM, respectively. Pricing for the RSC-4x line starts at less than $2 in 100k quantities, which includes all required speech technology code. Samples of the RSC-4128 and beta development tools are available immediately, with production quantities of all versions scheduled for release in Q3 2002. About Sensory, Inc.
