Voice Activity Detector. The challenge of power consumption in a voice-activated system

The interaction between humans and devices is increasingly carried out through voice control, be it for plugged or battery-powered devices. This unavoidable trend is made feasible thanks to the emergence of powerful signal processing algorithms capable to convert, with high success rate, the human speech to text but also to understand meaningful information, such as keywords and commands.

Dolphin Integration introduces a breakthrough Voice Activity Detector, the WhisperTrigger™, to provide ultra-low power Always-On Voice Listening for the longest-lasting operation without battery recharge and for environmentally friendly devices.
