Wake-up Triggers

Dolphin Integration brings wisdom to devices used in everyday life and expected to be power-aware, thanks to "Triggers" to wake them up only when needed, thus minimizing power consumption. In ultra-low power systems with a minimum in always-on mode, triggers play the key role of tracking activity-related events and awakening the relevant functions, which are otherwise turned-off the rest of the time. Our family of triggers has been widely adopted by leading fabless companies designing SoCs in need to detect various events while ensuring a positive effect on battery lifetime.

MIWOK™ - The Voice trigger benchmarks

The MIWOK™ benchmarks aim at providing reference testbenchs and procedures in order to evaluate the performances of any Voice Activity Detection (VAD) system. The benchmarks exist for Far-Field (DTV, STB) and Near-Field (wearable IoT, car communication) voice applications.

Benchmark contents

  • Recordings of words (Chinese or English) from different speakers
  • Recordings of noise sources in various application contexts
  • MATLAB Scripts for benchmark generation and performance computation
  • Readme file with detailed instructions
