商品描述

This book presents and develops several important concepts of speech enhancement in a simple but rigorous way. Many of the ideas are new; not only do they shed light on this old problem but they also offer valuable tips on how to improve on some well-known conventional approaches. The book unifies all aspects of speech enhancement, from single channel, multichannel, beamforming, time domain, frequency domain and time–frequency domain, to binaural in a clear and flexible framework. It starts with an exhaustive discussion on the fundamental best (linear and nonlinear) estimators, showing how they are connected to various important measures such as the coefficient of determination, the correlation coefficient, the conditional correlation coefficient, and the signal-to-noise ratio (SNR). It then goes on to show how to exploit these measures in order to derive all kinds of noise reduction algorithms that can offer an accurate and versatile compromise between noise reduction and speech distortion.

商品描述(中文翻譯)

本書以簡單而嚴謹的方式介紹和發展了語音增強的幾個重要概念。其中許多想法都是新的,它們不僅為這個古老的問題提供了新的見解,還提供了改進一些眾所周知的常規方法的寶貴提示。本書以清晰靈活的框架統一了語音增強的所有方面,包括單通道、多通道、波束成形、時域、頻域和時頻域,以及雙耳聽覺。它從對基本最佳(線性和非線性)估計器的詳盡討論開始,展示了它們與各種重要指標(如決定係數、相關係數、條件相關係數和信噪比)的聯繫。然後,它展示了如何利用這些指標來推導各種噪聲降低算法,以在噪聲降低和語音失真之間提供準確而靈活的折衷方案。
