Introduction

WhisperExtractor (aMFCC) is Dolphin Semiconductor’s groundbreaking IP that extracts Mel-Frequency Cepstral Coefficients (MFCC) directly from an analog microphone at just a few microwatts. By replacing conventional DSP-based word recognition with efficient analog-front end, it cuts energy use by ~99% and enables always-on event and voice detection in embedded devices. Come see the future of edge intelligence.
