The presence of environmental additive noise in the vicinity of the user typically degrades the speech intelligibility of speech processing applications. This intelligibility loss can be compensated by properly preprocessing the speech signal prior t

Optimizing Speech Intelligibility in a Noisy Environment: A unified view

Autor: W. B. Kleijn, Petko N. Petkov, Richard C. Hendriks, Peter Vary, Bastian Sauert, Joao B. Crespo

Publikováno v: IEEE Signal Processing Magazine. 32:43-54

Modern communication technology facilitates communication from anywhere to anywhere. As a result, low speech intelligibility has become a common problem, which is exacerbated by the lack of feedback to the talker about the rendering environment. In r

Multizone Speech Reinforcement

Autor: Joao B. Crespo, Richard C. Hendriks

Publikováno v: IEEE/ACM Transactions on Audio, Speech, and Language Processing. 22:54-66

In this article, we address speech reinforcement (near-end listening enhancement) for a scenario where there are several playback zones. In such a framework, signals from one zone can leak into other zones (crosstalk), causing intelligibility and/or

While most contributions on speech reinforcement only consider the presence of environmental noise, late reverberation can also severely degrade the intelligibility of speech. In this paper we address the problem of speech reinforcement in noisy and

Speech reinforcement with a globally optimized perceptual distortion measure for noisy reverberant channels

Autor: Richard C. Hendriks, Joao B. Crespo

Publikováno v: IWAENC

In this paper, a time-frequency weighting is proposed for speech reinforcement (near-end listening enhancement) in a noisy and reverberant environment, which optimizes a perceptual distortion measure globally for a number of time-frequency bins. Simu

Multizone near-end speech enhancement under optimal second-order magnitude distortion

Autor: Richard C. Hendriks, Joao B. Crespo

Publikováno v: WASPAA

In this article, we address near-end speech enhancement for a scenario where there are several playback zones. A signal model is explored, where effects of noise, reverberation and zone crosstalk are taken into account simultaneously. Through the sym
