Techniques in Speech Acoustics provides an introduction to the acoustic analysis and characteristics of speech sounds. The first part of the book covers aspects of the source-filter decomposition of speech, spectrographic analysis, the acoustic theory of speech production and acoustic phonetic cues. The second part is based on computational techniques for analysing the acoustic speech signal including digital time and frequency analyses, formant synthesis, and the linear predictive coding of speech. There is also an introductory chapter on the classification of acoustic speech signals which is relevant to aspects of automatic speech and talker recognition. The book intended for use as teaching materials on undergraduate and postgraduate speech acoustics and experimental phonetics courses; also aimed at researchers from phonetics, linguistics, computer science, psychology and engineering who wish to gain an understanding of the basis of speech acoustics and its application to fields such as speech synthesis and automatic speech recognition.

In communication acoustics, the communication channel consists of a sound source, a channel (acoustic and/or electric) and finally the receiver: the human auditory system, a complex and intricate system that shapes the way sound is heard. Thus, when developing techniques in communication acoustics, such as in speech, audio and aided hearing, it is important to understand the time–frequency–space resolution of hearing. This book facilitates the reader’s understanding and development of speech and audio techniques based on our knowledge of the auditory perceptual mechanisms by introducing the physical, signal-processing and psychophysical background to communication acoustics. It then provides a detailed explanation of sound technologies where a human listener is involved, including audio and speech techniques, sound quality measurement, hearing aids and audiology. Key features: Explains perceptually-based audio: the authors take a detailed but accessible engineering perspective on sound and hearing with a focus on the human place in the audio communications signal chain, from psychoacoustics and audiology to optimizing digital signal processing for human listening. Presents a wide overview of speech, from the human production of speech sounds and basics of phonetics to major speech technologies, recognition and synthesis of speech and methods for speech quality evaluation. Includes MATLAB examples that serve as an excellent basis for the reader’s own investigations into communication acoustics interaction schemes which intuitively combine touch, vision and voice for lifelike interactions.

Speech sound production is one of the most complex human activities: it is also one of the least well understood. This is perhaps not altogether surprising as many of the complex neurological and physiological processes involved in the generation and execution of a speech utterance remain relatively inaccessible to direct investigation, and must be inferred from careful scrutiny of the output of the system -from details of the movements of the speech organs themselves and the acoustic consequences of such movements. Such investigation of the speech output have received considerable impetus during the last decade from major technological advancements in computer science and biological transducing, making it possible now to obtain large quantities of quantative data on many aspects of speech articulation and acoustics relatively easily. Keeping pace with these advancements in laboratory techniques have been developments in theoretical modelling of the speech production process. There are now a wide variety of different models available, reflecting the different disciplines involved -linguistics, speech science and technology, engineering and acoustics. The time seems ripe to attempt a synthesis of these different models and theories and thus provide a common forum for discussion of the complex problem of speech production. Such an activity would seem particularly timely also for those colleagues in speech technology seeking better, more accurate phonetic models as components in their speech synthesis and automatic speech recognition systems.

The Acoustic Analysis Of Speech presents essential information on modern methods for the acoustic analysis of speech. It assumes only a modest technical background and is intended for the reader who wants to know the basic issues in speech analysis but does not have an extensive background in engineering, physics or mathematics. The book discusses the basic methods for the acoustic analysis of speech in relation to (a) the acoustic theory of speech production and (b) measures of primary interest to speech scientists, speech-language pathologists, linguists, psychologists or others who are interested in the acoustic signal of speech. Readers will gain an understanding of theory, methods and databases pertaining to speech acoustics. The book offers a simple and straightforward explanation of all aspects of acoustic analysis from recording the signal, to analysis methods, to sources of data on phonetic and suprasegmental aspects of speech. Includes reference to acoustic data for several languages in addition to English. The book is written at a general introductory level for course in Speech Science; Speech Acoustics; Experimental Phonetics and Laboratory Instrumentation for Speech and Hearing.

The Verbal Behavior (VB) approach is a form of Applied Behavior Analysis (ABA), that is based on B.F. Skinner's analysis of verbal behavior and works particularly well with children with minimal or no speech abilities. In this book Dr. Mary Lynch Barbera draws on her own experiences as a Board Certified Behavior Analyst and also as a parent of a child with autism to explain VB and how to use it. This step-by-step guide provides an abundance of information about how to help children develop better language and speaking skills, and also explains how to teach non-vocal children to use sign language. An entire chapter focuses on ways to reduce problem behavior, and there is also useful information on teaching toileting and other important self-help skills, that would benefit any child. This book will enable parents and professionals unfamiliar with the principles of ABA and VB to get started immediately using the Verbal Behavior approach to teach children with autism and related disorders.
