Development platform shows near-zero power voice activation

January 05, 2017 // By Julien Happich
Acoustic sensors developer Vesper, DSP Group and Sensory, Inc have created a turnkey development platform that boasts the lowest overall power consumption for far-field always-listening voice interfaces.

This platform is the first to achieve overall power consumption low enough to enable battery-powered always-listening far-field systems, the companies claim. The new development platform integrates Vesper’s VM1010 wake-on-sound piezoelectric MEMS microphone with DSP Group’s DBMD4, an ultra-low-power, always-on voice and audio processor based on Sensory’s Truly Handsfree voice control embedded algorithms. The platform gives developers the ability to initiate voice processing through Sensory’s wake-up word technology, which ensures that only a specific trigger word activates the device.
