Eliminating the negative effect of non-stationary environmental noise is a long-standing
research topic for automatic speech recognition but still remains an important challenge …

Acoustic vector sensor (AVS) has been recently researched and developed for acoustic
wave capturing and signal processing. Conventional array generally employs spatially …

Speech enhancement and separation are core problems in audio signal processing, with
commercial applications in devices as diverse as mobile phones, conference call systems …

A comprehensive guide to the theory and practice of signal enhancement and array signal
processing, including matlab codes, exercises and instructor and solution manuals …

The topic of spherical microphone array signal processing has been gaining importance
since the publications of Meyer and Elko around 2002, and fuelled by many others since …

The estimation of the time-and frequency-dependent coherent-to-diffuse power ratio (CDR)
from the measured spatial coherence between two omnidirectional microphones is …

Distant speech recognition (DSR) holds the promise of the most natural human computer
interface because it enables man-machine interactions through speech, without the …

In this paper, we present an overview on the topic of noise reduction in the short-time Fourier
transform (STFT) domain. First, we briefly review the conventional literature in the single-and …

Reduction of late reverberation can be achieved using spatio-spectral filters, such as the
multichannel Wiener filter. To compute this filter, an estimate of the late reverberation power …

A novel dual-microphone speech enhancement technique is proposed in the present paper.
The technique utilizes the coherence between the target and noise signals as a criterion for …
