This paper deals with speech enhancement in noisy reverberated environments where multiple speakers are active. The authors propose an advanced real-time speech processing front-end aimed at automatically reducing the distortions introduced by room reverberation in distant speech signals, also considering the presence of background noise, and thus to(More)
In the present work the inverse filtering problem for speech dereverberation in stationary conditions is addressed. In particular we consider the presence of multiple observables which has a beneficial impact of on room transfer functions (RTFs) invertibility. In actual acoustic enviroments the assumed knowledge of RTFs is usually altered by the presence of(More)
In the last decades, a great deal of research has been devoted to extending our capacity of verbal communication with computers through automatic speech recognition (ASR). Although optimum performance can be reached when the speech signal is captured close to the speaker’s mouth, there are still obstacles to overcome in making reliable distant speech(More)
Developing performing speech reinforcement systems to improve the intra-cabin communication quality among car passengers in different row seats, typically degraded by the distance between speakers (for instance in SUV and mini-van) and the noise presence within the cockpit, has represented a challenging issue within the related scientific community.
