Phonetics is a branch of linguistics that studies how humans produce and perceive sounds or, in the case of sign languages, the equivalent aspects of sign. Linguists who specialize in studying the physical properties of speech are phoneticians. The field of phonetics is traditionally divided into three sub-disciplines based on the research questions involved such as how humans plan and execute movements to produce speech, how various movements affect the properties of the resulting sound or how humans convert sound waves to linguistic information. Traditionally, the minimal linguistic unit of phonetics is the phone—a speech sound in a language which differs from the phonological unit of phoneme; the phoneme is an abstract categorization of phones and it is also defined as the smallest unit that discerns meaning between sounds in any given language.
The voiced alveolar approximant is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents the alveolar and postalveolar approximants is ⟨ɹ⟩, a lowercase letter r rotated 180 degrees. The equivalent X-SAMPA symbol is r\.
The open back unrounded vowel, or low back unrounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɑ⟩, and the equivalent X-SAMPA symbol is A. The letter ⟨ɑ⟩ is called script a because it lacks the extra hook on top of a printed letter a, which corresponds to a different vowel, the open front unrounded vowel. Script a, which has its linear stroke on the bottom right, should not be confused with turned script a,, which has its linear stroke on the top left and corresponds to a rounded version of this vowel, the open back rounded vowel.
The close-mid front unrounded vowel, or high-mid front unrounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨e⟩.
The open-mid central rounded vowel, or low-mid central rounded vowel, is a vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɞ⟩, and the equivalent X-SAMPA symbol is 3\. The symbol is called closed reversed epsilon. It was added to the IPA in 1993; before that, this vowel was transcribed ⟨ɔ̈⟩.
Ian Maddieson is British-American linguist and professor emeritus of linguistics at the University of New Mexico, in the United States. He has served as Vice-President of the International Phonetic Association, and Secretary of the Association for Laboratory Phonology. Maddieson is best known for his work in phonetics, and phonological typology. He spent most of his academic career at the University of California, Berkeley, where he often collaborated with Peter Ladefoged in describing the patterns of speech sounds in the world's spoken languages.
The open central unrounded vowel, or low central unrounded vowel, is a type of vowel sound, used in many spoken languages. While the International Phonetic Alphabet officially has no dedicated letter for this sound between front and back, it is normally written ⟨a⟩. If precision is required, it can be specified by using diacritics, typically centralized ⟨ä⟩.
Peter Nielsen Ladefoged was a British linguist and phonetician. He was Professor of Phonetics at University of California, Los Angeles (UCLA), where he taught from 1962 to 1991. His book A Course in Phonetics is a common introductory text in phonetics, and The Sounds of the World's Languages is widely regarded as a standard phonetics reference. Ladefoged also wrote several books on the phonetics of African languages. Prior to UCLA, he was a lecturer at the universities of Edinburgh, Scotland and Ibadan, Nigeria (1959–60).
The Sounds of the World's Languages, sometimes abbreviated SOWL, is a 1996 book by Peter Ladefoged and Ian Maddieson which documents a global survey of the sound patterns of natural languages. Drawing from the authors' own fieldwork and experiments as well as existing literature, it provides an articulatory and acoustic description of vowels and consonants from more than 300 languages. It is a prominent reference work in the field of phonetics.
Bruce Hayes is an American linguist and Distinguished Professor of Linguistics at the University of California, Los Angeles.
Louis M. Goldstein is an American linguist and cognitive scientist. He was previously a professor and chair of the Department of Linguistics and a professor of psychology at Yale University and is now a professor in the Department of Linguistics at the University of Southern California. He is a senior scientist at Haskins Laboratories in New Haven, Connecticut, and a founding member of the Association for Laboratory Phonology. Notable students of Goldstein include Douglas Whalen and Elizabeth Zsiga.
Catherine Phebe Browman was an American linguist and speech scientist. She received her Ph.D. in linguistics from the University of California, Los Angeles (UCLA) in 1978. Browman was a research scientist at Bell Laboratories in New Jersey (1967–1972). While at Bell Laboratories, she was known for her work on speech synthesis using demisyllables. She later worked as researcher at Haskins Laboratories in New Haven, Connecticut (1982–1998). She was best known for developing, with Louis Goldstein, of the theory of articulatory phonology, a gesture-based approach to phonological and phonetic structure. The theoretical approach is incorporated in a computational model that generates speech from a gesturally-specified lexicon. Browman was made an honorary member of the Association for Laboratory Phonology.
