The auditory system encodes the properties of sound that are essential to recognizing speech, but it’s a lot more complicated than that.. By. Prof. D. M. . Parshuramkar. Dept.. Of Physics. N. H. College, Bramhapuri. Introduction. . Acoustics. It is the interdisciplinary science that deals with the study of all mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound.. Providing a comprehensive view of speech science for beginning speech majors, this text gives a thorough yet understandable look at the production, acoustics and perception of speech. It treats basic areas of speech science, such as basic speech acoustics, instrumentation and speech perception with regard to theories and practical applications. Written in a clear, reader-friendly style, Speech Science Primer serves as an introduction to speech science and covers basic information on acoustics, the acoustic analysis of speech, speech anatomy and physiology, and speech perception. It also includes topics such as research methodology, speech motor control, and history/evolution of speech science. With its reader-friendly content and valuable online resources, Speech Science Primer: Physiology, Acoustics, and Perception of Speech, Sixth Edition is an ideal text for beginning speech pathology and audiology students and faculty. Providing a comprehensive view of speech science for beginning speech majors, this text gives a thorough yet understandable look at the production, acoustics and perception of speech. It treats basic areas of speech science, such as basic speech acoustics, instrumentation and speech perception with regard to theories and practical applications. 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. Julia . Hirschberg and Sarah . Ita. . Levitan.
