Sensory Develops SonicNet Wireless Technology

Sensory, Inc., leaders in speech technology for consumer products, announced SonicNet(TM) (patent pending), a new technology for communication between two or more electronic devices using audio frequencies. Sensory’s FluentChip(TM) 3 technology library for the RSC-4x family now includes SonicNet(TM) at no additional cost, which allows any RSC-4x enabled device to send and receive wireless communication with no additional components required beyond the usual microphone and speaker. This revolutionary approach offers a superior alternative to infrared communication in instances where line-of-sight is not optimal.

SonicNet can be implemented in some very useful and intriguing ways on RSC-4x enabled products. For example, appliances such as a microwaves or thermostats could be activated by receiving SonicNet(TM) commands from a remote location via a telephone call or over the Internet. Sonic tones transmitted through a television signal could activate devices that allow a user to interact with the TV broadcast. Toys could communicate with each other to simulate life-like interaction. The possibilities are endless, and all that is required is one of Sensory’s low-cost chips that also offers many other advanced speech and audio technologies.

SonicNet(TM) technology produces audio tones in the frequency range of 8 kHz, and transmits and receives 4 bits of data in 0.8 seconds or 8 bits of data in 1.2 seconds at up to 30 foot distances. SonicNet(TM) is characterized by immunity to room echoes or external sound sources that can cause false triggers, and can successfully receive sonic signals even in the midst of loud noise sources such as TV sets and stereos. In a typical application, the sonic tones are embedded in speech or sound effects so that the audio tones are at least partially hidden in the masking signal. In some applications, the sonic tones can be heard but they are non-obtrusive.

Sensory’s RSC-4x family includes the RSC-464 (64KB ROM on chip), RSC-4128 (128KB ROM) and the RSC 4192O (192KB OTP). These chips are capable of performing various functions including speaker independent recognition, speaker verification, music synthesis, speech compression and playback, and much more. An RSC-4x chip includes an 8 bit microcontroller with on-chip RAM, ROM/OTP, ADC, DAC, timers, comparators and more for a complete speech I/O system on chip. The RSC chips sell in die for under $2/chip in volume. Sensory also offers the VR Stamp(TM), a solution that simplifies the integration of speech recognition into products by combining all key components into a small 40-pin DIP footprint module.
