Always-on Digital Voice Activity Detection

WhisperTrigger allows your system to detect voice activity and increase its battery life.

Overview

WhisperTrigger allows your system to detect voice activity and increase its battery life. Our robust and silicon-proven, Voice Activity Detection solution, provides ultra-low-power Always-On Voice listening IP for a fast time to market. The WT-d.03 is a pure logic Virtual Component (ViC) containing a Voice Activity Detection (VAD) engine for ultra-low power applications. The WT-d detects the presence of a voice at the output of a DMIC or at the output of a voice ADC embedded on SoC to switch on the system to perform Keyword Spotting.

Key features

  • Voice activity detector enables drastic reduction in power consumption
  • Self-adjustment to background noise
  • Ambient Noise sensing
