The Interactive Speech™ Product Line
The Interactive Speech line of ICs and software was developed to “bring life to products” through advanced speech recognition and audio
technology.
The Interactive Speech Product Line was designed for consumer telephony products and cost-sensitive consumer electronic applications
such as home electronics, personal security, and personal communication.
The product line includes award-winning RSC series general-purpose microcontrollers and tools, SC series of speech microcontrollers, plus
a line of easy-to-implement chips that can be pin-configured or controlled by an external host microcontroller. Sensory’s software
technologies run on a variety of microcontrollers and DSPs.
RSC Microcontrollers and Tools
The RSC product line contains low-cost 8-bit speech-optimized microcontrollers designed for use in consumer
electronics. All members of the RSC family are fully integrated and include A/D, pre-amplifier, D/A, ROM, and RAM
circuitry. The RSC family can perform a full range of speech/audio functions including speech recognition, speaker
verification, speech and music synthesis, and voice record/playback. The family is supported by a complete suite of
evaluation tools and development kits.
SC Microcontrollers and Tools
The SC-6x product line features the highest quality speech synthesis ICs at the lowest data rate in the industry. The line includes a
12.32 MIPS processor for high-quality low data-rate speech compression and MIDI music synthesis, with plenty of power left over for
other processor and control functions. Members of the SC-6x line can store as much as 37 minutes of speech on chip and include as
much as 64 I/O pins for external interfacing. Integrating this broad range of features onto a single chip enables developers to create
products with high quality, long duration speech at very competitive price points.
Application Specific Standard Products (ASSPs)
Voice Direct™ 364 provides inexpensive speaker-dependent speech recognition and speech synthesis. This easy-to-use, pin-
configurable chip requires no custom programming and can recognize up to 60 trained words in slave mode, and 15 words in stand-
alone mode. Ideal for speaker-dependent command and control of household consumer products, Voice Direct 364 is part of a complete
product line that includes the IC, module, and Voice Direct 364 Speech Recognition Kit.
Voice Extreme™ simplifies the creation of fully custom speech-enabled products by offering developers the capability of
programming the chip in a high-level C-like language. Program code, speech data, and even record and playback
information can be stored on a single off-chip Flash memory. Based on Sensory's RSC-364 speech processor, Voice
Extreme includes a highly efficient on-chip code interpreter, and is supported by a comprehensive suite of low-cost
development tools.
Software and Technology
Voice Activation™ micro footprint software provides advanced speech technology on a variety of microcontroller and DSP
platforms. A flexible design with a broad range of technologies allows manufacturers to easily integrate speech functionality
into consumer electronic products.
Fluent Speech™ small footprint software recognizes up to 50,000 words; offers Animated Speech with the ability to automate
enunciation and articulation; performs text-to-speech synthesis in either male or female voices; provides noise and echo cancellation,
performs Wordspotting for natural language usage; offers telephone barge-in; and provides continuous digit recognition.
