Articulatory gestures are the actions necessary to enunciate language. Examples of articulatory gestures are the hand movements necessary to enunciate sign language and the mouth movements of speech. In semiotic terms, these are the physical embodiment (signifiers) of speech signs, which are gestural by nature (see below).
The definition of gesture varies greatly, but here it will be taken in its widest sense, namely, any meaningful action. An intentional action is meaningful if it is not strictly utilitarian: for example, sending flowers to a friend is a gesture, because this action is performed not only for the purpose of moving flowers from one place to another, but also to express some sentiment or even a conventional message in the language of flowers. Use of the broadest definition of gesture (not restricted to hand movements) allows Hockett's “rapid fading” design feature of human language to be accommodated as a type of sign in semiotic theory.
But if an articulatory gesture is to be considered a true gesture in the above sense, it must be meaningful. Therefore, an articulatory gesture must be at least as large as the smallest meaningful unit of language, the morpheme. A morpheme corresponds roughly to a spoken word or a sign language gesture.
This definition differs from the practice, common among linguists, of referring to phonemes (meaningless mouth movements) as articulatory gestures (see articulatory phonology). In semiotics, meaningless components of spoken gestures (written as individual letters), or meaningless components of sign language gestures (such as location of hand contact) are known as figurae, the constituents of signs.
It also differs from the tradition of considering speech sounds to be the signifiers of speech signs. But this practice confuses signals with symbols. Sound and light are analogue signals, whereas mouth and hand gestures are discrete symbolic entities. A sound or light signal is subject to random noise, whereas the image of the gesture is subject to regular distortion, as when a signer's hand is viewed from different angles. In speech, the sound of the contact of the tongue in the letter T can be distorted by surrounding mouth movements, as in the phrase “perfect memory”. When pronounced at conversational speed, the sound of the tongue contact is completely obscured by surrounding consonants even though this T movement is fully carried out.
Articulatory gestures, when seen as the physical embodiment of speech and sign language symbols, provide a link between these two language types, and show how speech resembles sign language more closely than is generally presumed.
Charles Francis Hockett was an American linguist who developed many influential ideas in American structuralist linguistics. He represents the post-Bloomfieldian phase of structuralism often referred to as "distributionalism" or "taxonomic structuralism". His academic career spanned over half a century at Cornell and Rice universities. Hockett was also a firm believer of linguistics as a branch of anthropology, making contributions that were significant to the field of anthropology as well.
Language is a structured system of communication that consists of grammar and vocabulary. It is the primary means by which humans convey meaning, both in spoken and signed forms, and may also be conveyed through writing. Human language is characterized by its cultural and historical diversity, with significant variations observed between cultures and across time. Human languages possess the properties of productivity and displacement, which enable the creation of an infinite number of sentences, and the ability to refer to objects, events, and ideas that are not immediately present in the discourse. The use of human language relies on social convention and is acquired through learning.
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.
In articulatory phonetics, the place of articulation of a consonant is a location along the vocal tract where its production occurs. It is a point where a constriction is made between an active and a passive articulator. Active articulators are organs capable of voluntary movement which create the constriction, while passive articulators are so called because they are normally fixed and are the parts with which an active articulator makes contact. Along with the manner of articulation and phonation, the place of articulation gives the consonant its distinctive sound.
A sign is an object, quality, event, or entity whose presence or occurrence indicates the probable presence or occurrence of something else. A natural sign bears a causal relation to its object—for instance, thunder is a sign of storm, or medical symptoms a sign of disease. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence; similarly the words and expressions of a language, as well as bodily gestures, can be regarded as signs, expressing particular meanings. The physical objects most commonly referred to as signs generally inform or instruct using written text, symbols, pictures or a combination of these.
In functional-cognitive linguistics, as well as in semiotics, iconicity is the conceived similarity or analogy between the form of a sign and its meaning, as opposed to arbitrariness. The principle of iconicity is also shared by the approach of linguistic typology.
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.
A gesture is a form of non-verbal communication or non-vocal communication in which visible bodily actions communicate particular messages, either in place of, or in conjunction with, speech. Gestures include movement of the hands, face, or other parts of the body. Gestures differ from physical non-verbal communication that does not communicate specific messages, such as purely expressive displays, proxemics, or displays of joint attention. Gestures allow individuals to communicate a variety of feelings and thoughts, from contempt and hostility to approval and affection, often together with body language in addition to words when they speak. Gesticulation and speech work independently of each other, but join to provide emphasis and meaning.
In semiotics, a sign is anything that communicates a meaning that is not the sign itself to the interpreter of the sign. The meaning can be intentional, as when a word is uttered with a specific meaning, or unintentional, as when a symptom is taken as a sign of a particular medical condition. Signs can communicate through any of the senses, visual, auditory, tactile, olfactory, or taste.
Articulation may refer to:
In linguistics, a segment is "any discrete unit that can be identified, either physically or auditorily, in the stream of speech". The term is most used in phonetics and phonology to refer to the smallest elements in a language, and this usage can be synonymous with the term phone.
Speech is the use of the human voice as a medium for language. Spoken language combines vowel and consonant sounds to form units of meaning like words, which belong to a language's lexicon. There are many different intentional speech acts, such as informing, declaring, asking, persuading, directing; acts may vary in various aspects like enunciation, intonation, loudness, and tempo to convey meaning. Individuals may also unintentionally communicate aspects of their social position through speech, such as sex, age, place of origin, physiological and mental condition, education, and experiences.
In linguistics, double articulation, duality of patterning, or duality is the fundamental language phenomenon consisting of the use of combinations of a small number of meaningless elements to produce a large number of meaningful elements. Its name refers to this two-level structure inherent to sign systems, many of which are composed of these two kinds of elements: 1) distinctive but meaningless and 2) significant or meaningful.
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.
The Columbia School of Linguistics is a group of linguists with a radically functional and empirical conception of language. According to their school of thought, the main function of language is communication, and it is this fact that guides the formulation of grammatical hypotheses and constrains the form these hypotheses can take. Columbia School linguistic analyses typically are based on observable data, such as corpora, not on introspective ad hoc sentence examples. Rather than a single theory of language, the Columbia School is a set of orientations in which scholars analyze actual speech acts in an attempt to explain why they take the forms they do. This was the methodology of its founder, the late William Diver, who taught linguistics at Columbia University until his retirement in 1989.
Figurae are the non-signifying constituents of signifiers (signs). For example, letters of the alphabet are the figurae that comprise a written word (signifier). In the semiotic language of Louis Hjelmslev, the coiner of this term, figurae serve only to distinguish elements of the expression plane from each other, independently from the content plane. That is, the letter B, in the written word expression "bat", distinguishes "bat" from the word "sat", but neither B nor S bears meaning on its own. On the other hand, the constituents "foot" and "ball" both bear their own individual meanings, such that in the word "football", they cannot be considered figurae, although their individual letters can. Hjelmslev states that in a given language a "legion of signs" can be constructed with a "handful of figurae" through ever new arrangements of them. Linguists often use the terms phonemes and morphemes to refer, respectively, to the figurae and the signifiers of human languages.
Apraxia of speech (AOS), also called verbal apraxia, is a speech sound disorder affecting an individual's ability to translate conscious speech plans into motor plans, which results in limited and difficult speech ability. By the definition of apraxia, AOS affects volitional movement pattern. However, AOS usually also affects automatic speech.
The origin of speech differs from the origin of language because language is not necessarily spoken; it could equally be written or signed. Speech is a fundamental aspect of human communication and plays a vital role in the everyday lives of humans. It allows them to convey thoughts, emotions, and ideas, and providing the ability to connect with others and shape collective reality.
Hockett's Design Features are a set of features that characterize human language and set it apart from animal communication. They were defined by linguist Charles F. Hockett in the 1960s. He called these characteristics the design features of language. Hockett originally believed there to be 13 design features. While primate communication utilizes the first 9 features, the final 4 features are reserved for humans. Hockett later added prevarication, reflexiveness, and learnability to the list as uniquely human characteristics. He asserted that even the most basic human languages possess these 16 features.
A phememe is a hypothesized speech sound with an abstract gestural meaning, proposed by the linguist Mary LeCron Foster.
