Silicon Deployment of Sensory’s Low Power Sound Detector for Always-Listening Voice Control Heats Up
The Low Power Sound Detector (LPSD) component of Sensory’s TrulyHandsfree technology is gaining significant traction among chip providers, being widely deployed as hardware within new chip designs
SANTA CLARA, Calif., – July 20, 2016 – Sensory Inc., a Silicon Valley company focused on improving the user experience and security of consumer electronics through state-of-the-art embedded voice and vision technologies, today announced that deployment of its Low Power Sound Detector (LPSD) hardware component of the company’s TrulyHandsfree technology is gaining steady traction among leading chip manufacturers. Finding its way into a variety of chip designs from DSPs, digital microphones and sensor fusion hubs, Sensory’s LPSD hardware block is currently shipping in product designs from DSP Group, Knowles and QuickLogic, with more chip partners to be announced. LPSD allows chip manufactures whose products are suited for enabling an always-listening speech recognition system on CE devices to greatly reduce the power requirements of their components, as well as the power demand of the entire speech recognition audio chain.
Ideal for always-on keyword trigger solutions that enable “Alexa,” “Hey Cortana,” “Hey Siri,” or “Okay Google” hands-free voice control on devices, Sensory’s LPSD was designed to only wake the audio chain for a keyword trigger when potential speech is sensed. The solution conserves power usage by allowing the remaining audio chain of a device to be switched off until needed for speech processing.
“Sensory has been the industry’s pioneer of low-power speech recognition technologies for more than 20 years and while our line of speech recognition solutions have always been extremely power efficient, we created our Low Power Sound Detector technology for those looking to integrate always-listening voice trigger technology into ultra-low-power devices,” said Todd Mozer, founder and CEO of Sensory.
LPSD was developed as a supplemental solution designed to enable low-power devices to operate Sensory’s TrulyHandsfree™ and other always-on, always-listening speech recognition technologies with minimal draw on the battery.
A hardware implementation of LPSD reduces the overall system power for always-listening keyword trigger technology by 50 percent. Depending on the mix of speech to silence, Sensory’s LPSD reduces processing requirements and lowers average power consumption (including digital microphone and decimation logic) of an always-on implementation to under 1mA, which has long been a target for use in wearables and battery operated consumer electronics (some cases require as little as 400uA).
“Sensory is the industry leader in voice processing systems for mobile applications,” said Brian Faith, CEO at QuickLogic Corporation. “Integration of Sensory's TrulyHandsfree and LPSD hardware with the QuickLogic EOS S3 multi-core sensor processing SoC provides unprecedented always-on speech recognition capability, and will facilitate a new generation of voice-driven applications capable of running on a fraction of the power consumption of competing technologies”.
