Speech Recognition
The RSC-4128 is designed to support HMM (Hidden Markov Modeling) as well as Neural Network technologies
provided in Sensory Speech 7 firmware, to perform speaker independent (SI) speech recognition. Speaker
independent recognition requires on-chip or off-chip ROM to store the words to be recognized.
Speaker dependent (SD) recognition requires programmable memory to store personalized speech templates.
This programmable memory may be on-chip SRAM or off-chip Serial EEPROM, Flash Memory, or SRAM.
The RSC-4128 has several additional speech recognition features as described below:
Speaker Independent
recognition requires no user training. The RSC-4128 can recognize up to 20 words in an
active set (number of sets is limited only by internal ROM or external memory size). Text-to-SI (T2SI) recognition,
based on HMM technology, allows creation of SI recognition sets in seconds by simply typing in the vocabulary
desired, with no costs or delays associated with recording and training the recognizer.
Speaker Dependent
recognition allows the user to create names for products or customize vocabularies. Up to
100 words can be recognized in an active set (number of sets is limited only by internal ROM or external memory
size). The RSC-4128 can store up to 10 SD words in on-chip SRAM.
Continuous Listening
allows the chip to continuously listen for a specific trigger word. With this feature, a product
“activates” when a specific word is spoken, framed by quiet before and after. Continuous listening provides the
lowest false fire rate for trigger words.
Word Spotting
allows the chip to continuously recognize for up to 10 SI or 5 SD words at a time. In word spotting
mode, the word(s) to be recognized may be spoken in the middle of speech.
Speaker Verification
The RSC-4128 also supports Sensory’s speaker verification (SV) technology – the most successful biometric
security on the market. After a speaker trains the chip on a specific word or words, the chip is able to identify
whether a particular word is spoken by the original speaker. The RSC-4128 can store up to 10 SV templates on-
chip, or more with external programmable memory.
Speech and Music Synthesis
The RSC-4128 provides high-quality speech synthesis using state-of-the-art frequency domain techniques in
Sensory’s new “SX” synthesis technology. Typical data rates for SX are approximately 6000 bits per second. One
may select various data rates from approximately 3.7 to 7.8Kbps to manage speech quality versus allotted memory.
Speech, music and sound effects may also be produced using the RSC-4128 8 bit, 58Kbps or 4 bit, 30Kbps
compression technologies.
The RSC-4128 provides high-quality, eight-voice, wave table music synthesis which allows multiple, simultaneous
instruments for harmonizing. The RSC-4128 uses a MIDI-like system to generate music. One or more of the eight
voices may be speech playback instead of music. One or more of the eight voices may be a drum track comprising
multiple drums. In effect, this allows the number of simultaneous instruments to exceed 8.
Speech and music synthesis requires on-chip or off-chip ROM to store data for synthesis playback. Easy to use
tools allow the developer to record and compress their own voice talents and create with the push of a button, or to
create their own MIDI scores and instruments.
Record and Playback
The RSC-4128 can perform speech record and playback (sometimes called “voice memo”) at various compression
levels depending on the quantity and quality of playback desired. Data rates less than 14,000 bits per second are
achievable while maintaining very high quality reproduction. The record and playback technology also performs
silence removal to improve sound quality and reduce memory requirements.
