This beautiful book celebrates the discovery of the hearing organ by the Italian anatomist Alfonso Corti in 1851. He first described the microscopic anatomy of the organ that contains the cellular receptors that transduce and carry airborne vibrations into electric signals to the auditory nerve and brain. Already by then, and still today, this organ was and is regarded as the most difficult of the organs in the human body to study. Indeed, it is a stealthy and miniscule organ surrounded by the hardest bone in the body. Since his discovery, researchers have continued to fascinate over this complex and gracile organ.

The fully updated, new edition of the bestselling introduction to phonetics and phonology The Sounds of Language presents a comprehensive introduction to both the physical and cognitive aspects of speech sounds. Assuming no prior knowledge of phonetics or phonology, this student-friendly textbook clearly explains fundamental concepts and theories, describes key phonetic and phonological phenomena, explores the history and intersection of the two fields, offers practical advice on collecting and reading data, and more. Twenty-four concise chapters, written in non-technical language, are organized into six sections that each focus on a particular sub-discipline: Articulatory Phonetics, Acoustic Phonetics, Segmental Phonology, Suprasegmental Phonology, the Phonology/Morphology Interface, and Variation and Change. The book's flexible modular approach allows instructors to easily choose, re-order, combine, or skip sections to meet the needs of one- and two-semester courses of varying levels. Now in its second edition, The Sounds of Language contains updated references, new problem sets, new examples, and links to new online material. The new edition features new chapters on Lexical Phonology; Word Structure and Sound Structure; and Variation, Probability, and Phonological Theory. Chapters on Sociolinguistic Variation, Child Language Acquisition, and Adult Language Learning have also been extensively updated and revised. Offering uniquely broad and balanced coverage of the theory and practice of two major branches of linguistics, The Sounds of Language: Covers a wide range of topics in phonetics and phonology, from the anatomy of the vocal tract to the cognitive processes behind the comprehension of speech sounds Features critical reviews of different approaches that have been used to address phonetics and phonology problems Integrates data on sociolinguistic variation, first language acquisition, and second language learning Surveys key phonological theories, common phonological processes, and computational techniques for speech analysis Contains numerous exercises and progressively challenging problem sets that allow students to practice data analysis and hypothesis testing Includes access to a companion website with additional exercises, sound files, and other supporting resources The Sounds of Language: An Introduction to Phonetics and Phonology, Second Edition, remains the ideal textbook for undergraduate and beginning graduate classes on phonology and phonetics, as well as related courses in linguistics, applied linguistics, speech science, language acquisition, and cognitive science programs.
