Audio source separation and speech enhancement

Learn the technology behind hearing aids, Siri, and Echo.

Audio source separation and speech enhancement aim to extract one or more source signals of interest from an audio recording involving several sound sources.

These technologies are among the most studied in audio signal processing today and bear a critical role in the success of hearing aids, hands-free phones, voice command and other noise-robust audio analysis systems, and music post-production software.

Research on this topic has followed three convergent paths, starting with sensor array processing, computational auditory scene analysis, and machine learning based approaches such as independent component analysis, respectively.

This book is the first one to provide a comprehensive overview by presenting the common foundations and the differences between these techniques in a unified setting.
