Phonetician
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 (articulatory phonetics), how various movements affect the properties of the resulting sound (acoustic phonetics), or how humans convert sound waves to linguistic information (auditory phonetics). 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. Phonetics deals with two aspects of human speech: production—the ways humans make sounds—and perception—the way speech is understood. The communicative modality ...

Cardinal Vowel
Cardinal vowels are a set of reference vowels used by phoneticians in describing the sounds of languages. They are classified depending on the position of the tongue relative to the roof of the mouth, how far forward or back is the highest point of the tongue, and the position of the lips (rounded or unrounded). A cardinal vowel is a vowel sound produced when the tongue is in an extreme position, either front or back, high or low. The current system was systematised by Daniel Jones in the early 20th century, though the idea goes back to earlier phoneticians, notably Ellis and Bell. Table of cardinal vowels Three of the cardinal vowels—, and —have articulatory definitions. The vowel is produced with the tongue as far forward and as high in the mouth as is possible (without producing friction), with spread lips. The vowel is produced with the tongue as far back and as high in the mouth as is possible, with protruded lips. This sound can be approximated by adopting ...

Articulatory Phonetics
The field of articulatory phonetics is a subfield of phonetics that studies articulation and ways that humans produce speech. Articulatory phoneticians explain how humans produce speech sounds via the interaction of different physiological structures. Generally, articulatory phonetics is concerned with the transformation of aerodynamic energy into acoustic energy. Aerodynamic energy refers to the airflow through the vocal tract. Its potential form is air pressure; its kinetic form is the actual dynamic airflow. Acoustic energy is variation in the air pressure that can be represented as sound waves, which are then perceived by the human auditory system as sound. Respiratory sounds can be produced by expelling air from the lungs. However, to vary the sound quality in a way useful for speaking, two speech organs normally move towards each other to contact each other to create an obstruction that shapes the air in a particular fashion. The point of maximum obstruction is cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Phonetic Alphabet
The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic transcription, phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of speech sounds in written form.International Phonetic Association (IPA), ''Handbook''. The IPA is used by lexicography, lexicographers, foreign language students and teachers, linguistics, linguists, speech–language pathology, speech–language pathologists, singers, actors, constructed language creators, and translators. The IPA is designed to represent those qualities of speech that are part of wiktionary:lexical, lexical (and, to a limited extent, prosodic) sounds in oral language: phone (phonetics), phones, phonemes, Intonation (linguistics), intonation, and the separation of words and syllables. To represent additional qualities of speech—such as tooth wiktionary:gnash, gnashing, lisping, and sounds made wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auditory Phonetics
Auditory phonetics is the branch of phonetics concerned with the hearing of speech sounds and with speech perception Speech perception is the process by which the sounds of language Language is a structured system of communication. The structure of a language is its grammar and the free components are its vocabulary. Languages are the primary means by wh .... It thus entails the study of the relationships between speech stimuli and a listener's responses to such stimuli as mediated by mechanisms of the peripheral and central auditory systems, including certain areas of the brain. It is said to compose one of the three main branches of phonetics along with acoustic phonetics, acoustic and articulatory phonetics, though with overlapping methods and questions. Physical scales and auditory sensations There is no direct connection between auditory sensations and the physical properties of sound that give rise to them.

Peter Ladefoged
Peter Nielsen Ladefoged ( , ; 17 September 1925 – 24 January 2006) 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'' (co-authored with Ian Maddieson) 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 (1953–59, 1960–1) and Ibadan, Nigeria (1959–60). Early life Peter Ladefoged was born on 17 September 1925, in Sutton (then in Surrey, now in Greater London), England. He attended Haileybury College from 1938 to 1943, and Gonville and Caius College, Cambridge, Cambridge University from 1943 to 1944. He received an MA (1951) and a PhD (1959) in Phonetics from the University of Edinburgh in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonemes
In phonology and linguistics, a phoneme () is a unit of sound that can distinguish one word from another in a particular language. For example, in most dialects of English, with the notable exception of the West Midlands and the north-west of England, the sound patterns (''sin'') and (''sing'') are two separate words that are distinguished by the substitution of one phoneme, , for another phoneme, . Two words like this that differ in meaning through the contrast of a single phoneme form a '' minimal pair''. If, in another language, any two sequences differing only by pronunciation of the final sounds or are perceived as being the same in meaning, then these two sounds are interpreted as phonetic variants of a single phoneme in that language. Phonemes that are established by the use of minimal pairs, such as ''tap'' vs ''tab'' or ''pat'' vs ''bat'', are written between slashes: , . To show pronunciation, linguists use square brackets: (indicating an aspirated ''p'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acoustic Phonetics
Acoustic phonetics is a subfield of phonetics, which deals with acoustic aspects of speech sounds. Acoustic phonetics investigates time domain features such as the mean squared amplitude of a waveform, its duration, its fundamental frequency, or frequency domain features such as the frequency spectrum, or even combined spectrotemporal features and the relationship of these properties to other branches of phonetics (e.g. articulatory or auditory phonetics), and to abstract linguistic concepts such as phonemes, phrases, or utterances. The study of acoustic phonetics was greatly enhanced in the late 19th century by the invention of the Edison phonograph. The phonograph allowed the speech signal to be recorded and then later processed and analyzed. By replaying the same speech signal from the phonograph several times, filtering it each time with a different band-pass filter, a spectrogram of the speech utterance could be built up. A series of papers by Ludimar Hermann published ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oralism
Oralism is the education of deaf students through oral language by using lip reading, speech, and mimicking the mouth shapes and breathing patterns of speech.Through Deaf Eyes. Diane Garey, Lawrence R. Hott. DVD, PBS (Direct), 2007. Oralism came into popular use in the United States around the late 1860s. In 1867, the Clarke School for the Deaf in Northampton, Massachusetts, was the first school to start teaching in this manner. Oralism and its contrast, manualism, manifest differently in deaf education and are a source of controversy for involved communities. Oralism should not be confused with Listening and Spoken Language, a technique for teaching deaf children that emphasizes the child's perception of auditory signals from hearing aids or cochlear implants. History Early 18th century Since the beginning of formal deaf education in the 18th century in the United States, manualism and oralism have been on opposing sides of a heated debate that continues to this day.Winefiel ...
