Sensory Introduces Speech Recognition Microcontrollers
SANTA CLARA, Calif. - Sensory, Inc. released the RSC-464 integrated circuit as the latest member of the RSC-4x family. It joins the RSC-4128 speech recognition IC. The RSC-464 also comes to market supported by a suite of tools.
RSC-464 Supplies General Control with Speech I/O
Sensory's RSC-464 integrated circuit allows manufacturers to replace existing 8-bit microcontrollers with a voice-enabled solution. The RSC-464 is a general-purpose microcontroller inside a speech recognition system-on-chip that includes 16-bit ADC, DAC, digital filter unit, math unit, 4K RAM, 64K ROM, output amplification, timers, comparators and more.
RSC-464 Implements New FluentChip™ 2.0 Technologies
A variety of technologies in Sensory's FluentChip™ firmware library run on the RSC-464, including speaker independent (SI) recognition, speaker dependent (SD) recognition, speaker verification (voice password) biometrics, voice record, speech compression/playback and MIDI-like music synthesis. FluentChip™ 2.0 offers new options for combining SI and SD in a command set, allowing for personalization. Also available is a new technology that allows the RSC-464 to control mouth movements of animated dolls.
Development Tools Enable International Vocabulary Development
Sensory's Quick T2SITM (Text to Speaker Independent) Toolkit complements the RSC-464 as it allows for creation of speaker independent command sets by typing in the desired recognition vocabulary as text. The recognition set of words or phrases can then be downloaded onto the included RSC-4x Demo/Evaluation Board for prototype creation and testing. These recognition technologies are derived from a database of sampled speech and are based on the rules of phonology - the environment in which sounds occur in languages. This approach is now available in U.S. English, German, Italian, Latin American Spanish, Japanese, Korean, and Mandarin Chinese, with UK English and French available later this year. Compressed speech is now available in any language as well.
Additional tools include Quick Synthesis, which allows development of speech output files by recording and compressing a file with the touch of a button, and also supports scoring of MIDI-like music. An integrated IDE for software development is provided by Phyton, Inc., including assembler, linker, debugger and file management, as well as an optional C compiler to accelerate coding.
