The Acoustics of Speech Communication by James M. Pickett Pdf

This is the only book to relate all three of the currently interactive areas of speech science-acoustic phonetics, speech perception, and speech technology. The book presents a gradual course, starting with a clear tutorial approach to basic speech then leading to speech perception research, the various theories of speech perception, and the modern speech technologies of computer synthesis and recognition of speech messages. The aim is to bring the reader through basic acoustics, spectrum analysis, vowel and consonant acoustics, and into the research literature of speech perception technology. The basic acoustic theory of speech production, the Source-Filter Theory, is clarified via text and diagrams. This knowledge is then applied to interpreting spectrograms of speech examples that sample all the phonetic distinctions among vowels and consonants. Distinctive acoustical patterns for vowel and consonant perception by listeners are summarized in detail based on the research literature. Critical discussions provide theories of motor, auditory, and computer recognition of speech. Consonant and vowel recognition by the hearing-impaired is described in relation to acoustic phonetic distinctions. Techniques of speech synthesis, recognition analysis by machines, and speech technologies are thoroughly explained. Anyone interested in speech acoustics, acoustic phonetics, speech and hearing science, psychoacoustics, and speech perception at any level.

Communication Acoustics by Ville Pulkki,Matti Karjalainen Pdf

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.

Elements of Acoustic Phonetics by Peter Ladefoged Pdf

This revised and expanded edition of a classic textbook provides a concise introduction to basic concepts of acoustics and digital speech processing that are important to linguists, phoneticians, and speech scientists. The second edition includes four new chapters that cover new experimental techniques in acoustic phonetics made possible by the use of computers. Assuming no background in physics or mathematics, Ladefoged explains concepts that must be understood in using modern laboratory techniques for acoustic analysis, including resonances of the vocal tract and the relation of formants to different cavities; digital speech processing and computer storage of sound waves; and Fourier analysis and Linear Predictive Coding, the equations used most frequently in the analysis of speech sounds. Incorporating recent developments in our knowledge of the nature of speech, Ladefoged also updates the original edition's discussion of the basic properties of sound waves; variations in loudness, pitch, and quality of speech sounds; wave analysis; and the hearing and production of speech. Like its predecessor, this edition of Elements of Acoustic Phonetics will serve as an invaluable textbook and reference for students and practitioners of linguistics and speech science, and for anyone who wants to understand the physics of speech.

Acoustics of American English Speech by Joseph P. Olive,Alice Greenwood,John Coleman Pdf

This book presents the most contemporary and comprehensive description of the acoustics of the sounds used in American English. Intended to serve as an introductory text for students and professionals interested in acoustic phonetics, linguistics, physics, electrical engineering, and computer science, the authors bring to the subject the points of view of both linguistics and physics. The book uses numerous examples of acoustic spectrograms to show the continuities and variability of natural speech. The book begins by introducing the basic concepts of phonetics, phonology, and linguistics to readers whose background is in physics or engineering and introducing the physics of sound generation and analysis for speech scientists and linguists. The authors then use the tools developed in the first part to examine the characteristics of individual phonemes as well as the changes introduced when individual sounds are combined in speech. Modern applications of speech acoustics, especially speech synthesis and recognition, are also discussed.

Speech Production by Jonathan Harrington,Marija Tabain Pdf

Speech Production: Models, Phonetic Processes and Techniques brings together researchers from many different disciplines - computer science, dentistry, engineering, linguistics, phonetics, physiology, psychology - all with a special interest in how speech is produced. From the initial neural program to the end acoustic signal, it provides an overview of several dominant models in the speech production literature, as well as up-to-date accounts of persistent theoretical issues in the area. A particular focus is on the evaluation of information gleaned from instrumental investigations of the speech production process, including MRI, PET, ultra-sound, video-imaging, EMA, EPG, X-ray, computer simulation - and many others. The research presented in this volume considers questions such as: the feed-back vs. feed-forward control of speech; the acoustic/auditory vs. articulatory/somato-sensory domains of speech planning; the innateness of human speech; the possible architecture of a speech production model; and the realization of prosodic structure in speech. Leaders in speech research from around the world have contributed their most recent work to this volume.

Speech Production and Speech Modelling by W.J. Hardcastle,Alain Marchal Pdf

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.

Techniques for Noise Robustness in Automatic Speech Recognition by Tuomas Virtanen,Rita Singh,Bhiksha Raj Pdf

Automatic speech recognition (ASR) systems are finding increasing use in everyday life. Many of the commonplace environments where the systems are used are noisy, for example users calling up a voice search system from a busy cafeteria or a street. This can result in degraded speech recordings and adversely affect the performance of speech recognition systems. As the use of ASR systems increases, knowledge of the state-of-the-art in techniques to deal with such problems becomes critical to system and application engineers and researchers who work with or on ASR technologies. This book presents a comprehensive survey of the state-of-the-art in techniques used to improve the robustness of speech recognition systems to these degrading external influences. Key features: Reviews all the main noise robust ASR approaches, including signal separation, voice activity detection, robust feature extraction, model compensation and adaptation, missing data techniques and recognition of reverberant speech. Acts as a timely exposition of the topic in light of more widespread use in the future of ASR technology in challenging environments. Addresses robustness issues and signal degradation which are both key requirements for practitioners of ASR. Includes contributions from top ASR researchers from leading research units in the field
