Sensory's RSC-4x Voice IC's Now Support Asian and European Languages
Sensory announced the availability of five new languages to be supported by Sensory's RSC-4x line of speech recognition chips and associated tools. In addition to American English, speech developers can now create embedded applications in German, Spanish, Japanese, Korean, and soon in Mandarin Chinese. RSC-4x Series Microcontrollers Supply General Control with Speech I/O Sensory's RSC-4128 integrated circuit allows manufacturers to replace existing eight bit microcontrollers with a voice-enabled solution. Adding speech I/O is becoming increasingly popular in the next generation of user interfaces for consumer electronic products, allowing ease of use and functionality never before available. The RSC-4128 is actually a general-purpose microcontroller inside a voice-recognition-system-on-chip (including 16 bit ADC, DAC, digital filter unit, math unit, 4K RAM, 128K ROM, output amplification, timers, comparators and more). A variety of technologies run on this chip, including speaker independent recognition, speaker dependent recognition, speaker verification, voice record, speech compression/playback and midi-like music synthesis.
Sensory's new speaker independent (SI) technologies use Hidden Markov Modeling combined with neural networks to eliminate the need for user training. 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.
Sensory's Quick T2SI Toolkit (Text to Speaker Independent) complements the RSC-4x line as it allows the creation of speaker independent sets by typing in the desired vocabulary words as text. The speaker independent recognition set of words or phrases can then be downloaded onto the included RSC-4x Demo/Evaluation board for prototype creation and testing.
