这本书是对波和信号处理的基本概念的半技术性介绍。它主要是为言语和听力科学专业的大学生设计的。它的写作角度是信号和系统分析，呈现在一个不是工程或物理专业的学生可以管理的水平上。正如封底所述，许多从事言语和听力科学领域工作的人带着从心理学到语言学再到生命科学的不同背景来到这个领域。通常，他们缺乏技术背景，这使得教师很难以统一和连贯的方式呈现材料，并提供足够的基本材料，以便在现实的水平上进行理解。看到这种材料以一种新颖的方式呈现出来，令人耳目一新。罗森和豪厄尔是《言语和听力的信号和系统》(以下简称SSSH)的作者，他们的努力大多取得了成功，应该受到赞扬。SSSH不是对言语和听力科学的介绍，但实际上课文中的所有例子都来自这些领域。SSSH首先阐述了什么是信号和系统，以及它们与我们处理的对象的关系，首先是在我们的日常经验中，然后是在更特别地处理语音和听觉的情况下。在介绍了演示所需的主要工具之后，SSSH依次介绍了系统的频率响应、信号的频谱特征以及信号经过不同系统时会发生什么。然后介绍了系统的时间特性以及脉冲响应和频率响应之间的关系。更多关于时间域和频率域之间关系的讨论，导致了光谱分析。进入听力系统的一小段插曲之后是语音的回归和语音产生的源过滤理论。最后一章介绍了数字系统，它们的优点和缺点，以及如何使用数字方法处理前几章中提出的概念，以并行模拟方法的方式。这位评论家在一些不影响内容价值的小问题上有一些吹毛求疵的地方，但有时可能会误导或迷惑读者和/或阻止使用这本书的学生学习既定的惯例。
This book is a semi-technical introduction to the basic concepts of waves and signal processing. It is intended primarily for college students in speech and hearing sciences programs. The perspective from which it is written is that of signals and systems analysis, presented at a level manageable by students who are not in engineering or in physics. As stated on the back cover, many people working in the area of speech and hearing sciences come to the field with diverse backgrounds ranging from psychology to linguistics to the life sciences. Often, their lack of technical background makes it hard for the teacher t o present the materials in a unified and coherent way, with enough basic material to allow understanding at a realistic level. It is quite refreshing to see this type of material presented in a novel way. Rosen and Howell, the authors of “Signals and Systems for Speech and Hearing” (henceforth SSSH) have mostly succeeded in their endeavour and should be commended for it. SSSH is not an introduction to speech and hearing sciences, but practially all the examples in the text are drawn from these areas. SSSH starts with an exposition of what signals and systems are and how they relate to objects we deal with, first in our daily experience, then in situations dealing more particularly with speech and hearing. Having introduced the primary tools needed for the presentation, SSSH presents in turn the frequency response of systems, the frequency characterization of signals in spectral terms, and what happens to signals when they are put through different systems. It then presents the time characterization of systems and how impulse response and frequency response relate to each other. More discussion of the relation between time domain and frequency domain follows, leading to spectrographic analysis. A short interlude into the hearing system is followed by a return to speech and the source-filter theory of speech production. The last chapter introduces digital systems, their strengths and weaknesses, and how the concepts presented in the previous chapters can be handled using digital methods, in ways that parallel analog methods. This reviewer has a few quibbles having to do with minor points which do not affect the value of the contents but at times may mislead or confuse the reader and/or prevent the student using this book from learning well-established conventions.
