Supervised Noise Reduction for Multichannel Keyword Spotting

Yiteng Huang, Thad Hughes, Turaj Zakizadeh Shabestary, Taylor Applebaum

ICASSP 2018accepted

This paper presents a robust, small-footprint, far-field keyword spotting (KWS) algorithm, which was inspired by the human auditory system's ability to achieve the so-called cocktail party effect in adverse acoustic environments. It introduces the idea of combining microphone-array speech enhancemen…

Trainable frontend for robust and far-field keyword spotting

Yuxuan Wang, Pascal Getreuer, Thad Hughes, Richard F. Lyon, Rif A. Saurous

ICASSP 2017accepted

Robust and far-field speech recognition is critical to enable true hands-free communication. In far-field conditions, signals are attenuated due to distance. To improve robustness to loudness variation, we introduce a novel frontend called per-channel energy normalization (PCEN). The key ingredient…
