Sensory Optimizes TrulyHandsfree Voice Control Software for Synopsys' DesignWare ARC EM5D Processor

Synopsys and Sensory today announced the availability of an optimized port of Sensory's TrulyHandsFree voice control software for the Synopsys DesignWare ARC EM digital signal processors.

The ARC EM5D processor consumes less than one microwatt of power executing TrulyHandsfree low-power sound detection software, and less than 40 microwatts operating in speech recognition mode. The combination of Sensory's voice control technology running on power-efficient and DSP-enhanced ARC EM processor cores enables designers to integrate a complete, ultra-low energy hardware-software solution for voice/speech processing into their "always-on" devices.

"The trend towards greater numbers of voice-enabled IoT devices is driving the need for integrated hardware and software solutions that can deliver excellent performance while keeping power consumption at a minimum to extend battery life," said Bernard Brafman, vice president of business development at Sensory, in a statement. "By optimizing Sensory's ultra-low power TrulyHandsfree technology for the highly efficient DesignWare ARC EM5D processor, we are providing designers with the ability to implement highly accurate voice activation capabilities within the stringent power and performance parameters of their designs."

Sensory's TrulyHandsfree voice control technology offers multiple phrase technology that recognizes, analyzes, and responds to dozens of keywords. It consistently recognizes phrases even when embedded in sentences and surrounded by noise, operating reliably in close to 0 dB signal-to-noise ratio real-world environments. TrulyHandsfree can deliver more than 95 percent accuracy without false fires even in high noise and speech. Ultra-low power consumption in detection and recognition modes extends battery life for always-on Internet-of-Things (IoT) and wearable devices.

"Consumer and IoT devices with voice activation capabilities are becoming ubiquitous and demand more sophisticated solutions that can deliver the required performance with very low power," said John Koeter, vice president of marketing for IP and prototyping at Synopsys, in a statement. "With the optimized port of Sensory's TrulyHandsfree voice control software for the ultra-low power ARC EM processors, we're helping designers integrate the broad range of voice detection and control features they need without compromising the battery life of their always-on applications."

Sensory also announced the immediate availability of its TrulyHandsfree Voice Control 3.0 technology on the first of several planned platforms from Qualcomm. With this announcement, Qualcomm's broad mobile OEM customer base will be able to integrate Sensory's advanced low-power, voice trigger and voice control solutions into their products. Fully integrated with Qualcomm's next-generation WCD9330 codec framework, TrulyHandsfree is delivered as a library-based port, deeply embedded and optimized for memory and processing cycles.

"With our TrulyHandsfree technology's industry-leading accuracy, even in noisy environments, its broad language support, and world-class power consumption, combined with Qualcomm's vast codec adoption among mobile manufacturers, more mobile OEMs will now be able to integrate their products with an industry-leading hands-free experience," said Bill Teasley, vice president of engineering at Sensory, in a statement. "As the pioneer of voice control on Bluetooth chips, we are thrilled to be working with the mobile industry's leading chip provider and to be the only third-party voice control partner on the WCD9330 platform.
