CEVA and Sensory partner to deliver low power voice activation on DSP core


CEVA, Inc. and Sensory, Inc. have partnered to offer an advanced voice recognition solution based on CEVA-TeakLite-4 DSP and Sensory’s TrulyHandsfree always-on voice activation technology. The solution includes Sensory’s Low Power Speech Detector technology, which dramatically reduces power consumption for always-listening devices, and marks the first time this technology has been implemented on a DSP core, according to the companies. Sensory’s voice activation technology consumes less than 60uW on the DSP when implemented in a 28nm process.

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 in a noisy environment. The fully programmable CEVA-TeakLite-4 DSP provides processing power to implement such advanced algorithms, while leaving plenty of headroom to support other audio/voice related functions in software.

The CEVA-TeakLite-4 is offered as an architecture framework, composed of four DSP cores, the TL410/TL411/TL420/TL421, all having a 32-bit native data width required for advanced pre and post-processing voice/audio applications. By taking advantage of a unified development infrastructure composed of code-compatible cores, a set of optimized software libraries and a unified tool chain, customers can significantly reduce software development costs while leveraging their software investment in future products.

The companies will demonstrate Sensory’s TrulyHandsfree Voice Control running on CEVA silicon at the upcoming Mobile World Congress in CEVA’s booth (Stand 7i70) .
