American Sign Language Phonology
Sign languages such as American Sign Language (ASL) are characterized by phonological processes analogous to, yet dissimilar from, those of oral languages. Although there is a qualitative difference from oral languages in that sign-language phonemes are not based on sound, and are spatial in addition to being temporal, they fulfill the same role as phonemes in oral languages. Basically, three types of signs are distinguished: one-handed signs, symmetric two-handed signs (i.e. signs in which both hands are active and perform the same or a similar action), and asymmetric two-handed signs (i.e. signs in which one hand is active he 'dominant' or 'strong' handand one hand is held static he 'non-dominant' or 'weak' hand. The non-dominant hand in asymmetric signs often functions as the location of the sign. Almost all simple signs in ASL are monosyllabic. Phonemes and features Signs consist of units smaller than the sign. These are often subdivided into ''parameters'': handshapes with ...

Sign Language
Sign languages (also known as signed languages) are languages that use the visual-manual modality to convey meaning, instead of spoken words. Sign languages are expressed through manual articulation in combination with non-manual markers. Sign languages are full-fledged natural languages with their own grammar and lexicon. Sign languages are not universal and are usually not mutually intelligible, although there are also similarities among different sign languages. Linguists consider both spoken and signed communication to be types of natural language, meaning that both emerged through an abstract, protracted aging process and evolved over time without meticulous planning. Sign language should not be confused with body language, a type of nonverbal communication. Wherever communities of deaf people exist, sign languages have developed as useful means of communication and form the core of local Deaf cultures. Although signing is used primarily by the deaf and hard of hearing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chereme
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'' in ''p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wendy Sandler
Wendy Sandler is an American-Israeli linguist who is known for her research on the phonology of Sign Languages. Sandler earned her PhD in linguistics from the University of Texas at Austin in 1987, with a dissertation entitled "Sequentiality and simultaneity in American Sign Language." A revised version of her dissertation was published in 1989 under the title, "Phonological Representation of the Sign: Linearity and Nonlinearity in Sign Language Phonology." After her dissertation, Sandler took up a position at the University of Haifa, Israel, where she became a Professor of Linguistics in the Department of English Language and Literature. She was also the Founding Director of the Sign Language Research Lab there. Sandler has co-written a book on Israeli Sign Language with Irit Meir (Meir & Sandler 2007). With Diane Lillo-Martin, she has co-authored a standard linguistic introduction to the phonology and syntax of American Sign Language (Sandler & Lillo-Martin 2006). In coll ...

Tone (linguistics)
Tone is the use of pitch in language to distinguish lexical or grammatical meaning – that is, to distinguish or to inflect words. All verbal languages use pitch to express emotional and other paralinguistic information and to convey emphasis, contrast and other such features in what is called intonation (linguistics), intonation, but not all languages use tones to distinguish words or their inflections, analogously to consonants and vowels. Languages that have this feature are called tonal languages; the distinctive tone patterns of such a language are sometimes called tonemes, by analogy with ''phoneme''. Tonal languages are common in East and Southeast Asia, Africa, the Americas and the Pacific. Tonal languages are different from Pitch-accent language, pitch-accent languages in that tonal languages can have each syllable with an independent tone whilst pitch-accent languages may have one syllable in a word or morpheme that is more prominent than the others.

Pitch Contour
__NOTOC__ In linguistics, speech synthesis, and music, the pitch contour of a sound is a function or curve that tracks the perceived pitch of the sound over time. Pitch contour may include multiple sounds utilizing many pitches, and can relate the frequency function at one point in time to the frequency function at a later point. It is fundamental to the linguistic concept of tone, where the pitch or change in pitch of a speech unit over time affects the semantic meaning of a sound. It also indicates intonation in pitch accent languages. One of the primary challenges in speech synthesis technology, particularly for Western languages, is to create a natural-sounding pitch contour for the utterance as a whole. Unnatural pitch contours result in synthesis that sounds "lifeless" or "emotionless" to human listeners, a feature that has become a stereotype of speech synthesis in popular culture. In music, the pitch contour focuses on the relative change in pitch over time of a prima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosody (linguistics)
In linguistics, prosody () is concerned with elements of speech that are not individual phonetic segments (vowels and consonants) but are properties of syllables and larger units of speech, including linguistic functions such as intonation, stress, and rhythm. Such elements are known as suprasegmentals. Prosody may reflect features of the speaker or the utterance: their emotional state; the form of utterance (statement, question, or command); the presence of irony or sarcasm; emphasis, contrast, and focus. It may reflect elements of language not encoded by grammar or choice of vocabulary. Attributes of prosody In the study of prosodic aspects of speech, it is usual to distinguish between auditory measures ( subjective impressions produced in the mind of the listener) and objective measures (physical properties of the sound wave and physiological characteristics of articulation that may be measured objectively). Auditory (subjective) and objective ( acoustic and articulatory) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonotactic
Phonotactics (from Ancient Greek "voice, sound" and "having to do with arranging") is a branch of phonology that deals with restrictions in a language on the permissible combinations of phonemes. Phonotactics defines permissible syllable structure, consonant clusters and vowel sequences by means of ''phonotactic constraints''. Phonotactic constraints are highly language-specific. For example, in Japanese, consonant clusters like do not occur. Similarly, the clusters and are not permitted at the beginning of a word in Modern English but are in German and Dutch (in which the latter appears as ) and were permitted in Old and Middle English. In contrast, in some Slavic languages and are used alongside vowels as syllable nuclei. Syllables have the following internal segmental structure: * Onset (optional) * Rhyme (obligatory, comprises nucleus and coda): ** Nucleus (obligatory) ** Coda (optional) Both onset and coda may be empty, forming a vowel-only syllable, or alternativel ...

Assimilation (linguistics)
Assimilation is a sound change in which some phonemes (typically consonants or vowels) change to become more similar to other nearby sounds. A common type of phonological process across languages, assimilation can occur either within a word or between words. It occurs in normal speech but becomes more common in more connected speech, rapid speech. In some cases, assimilation causes the sound spoken to differ from the normal pronunciation in isolation, such as the prefix ''in-'' of English ''input'' pronounced with phonetic [m] rather than [n]. In other cases, the change is accepted as canonical for that word or phrase, especially if it is recognized in standard spelling: ''implant'' pronounced with [m], composed historically of ''in'' + ''plant''. English "handbag" (canonically ) is often pronounced in rapid speech because the and sounds are both bilabial consonants, and their places of articulation are similar. However, the sequence - has different places but similar man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allophone
In phonology, an allophone (; from the Greek , , 'other' and , , 'voice, sound') is a set of multiple possible spoken soundsor ''phones''or signs used to pronounce a single phoneme in a particular language. For example, in English, (as in ''stop'' ) and the aspirated form (as in ''top'' ) are allophones for the phoneme , while these two are considered to be different phonemes in some languages such as Thai. On the other hand, in Spanish, (as in ''dolor'' ) and (as in ''nada'' ) are allophones for the phoneme , while these two are considered to be different phonemes in English. The specific allophone selected in a given situation is often predictable from the phonetic context, with such allophones being called positional variants, but some allophones occur in free variation. Replacing a sound by another allophone of the same phoneme usually does not change the meaning of a word, but the result may sound non-native or even unintelligible. Native speakers of a given languag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distinctive Feature
In linguistics, a distinctive feature is the most basic unit of phonological structure that distinguishes one sound from another within a language. For example, the feature oicedistinguishes the two bilabial plosives: and There are many different ways of defining and arranging features into ''feature systems'': some deal with only one language while others are developed to apply to all languages. Distinctive features are grouped into categories according to the natural classes of segments they describe: major class features, laryngeal features, manner features, and place features. These feature categories in turn are further specified on the basis of the phonetic properties of the segments in question. For phonemes to be in a particular natural class, they have to share the same distinctive features such as articulation and/or sound similar to each other. We can find distinctive features between two words by finding the minimal pair between them. The minimal pair are when two ...

American Sign Language
American Sign Language (ASL) is a natural language that serves as the predominant sign language of Deaf communities in the United States of America and most of Anglophone Canadians, Anglophone Canada. ASL is a complete and organized visual language that is expressed by employing both manual and nonmanual features. Besides North America, dialects of ASL and ASL-based creole language, creoles are used in many countries around the world, including much of West Africa and parts of Southeast Asia. ASL is also widely learned as a second language, serving as a lingua franca. ASL is most closely related to French Sign Language (LSF). It has been proposed that ASL is a creole language of LSF, although ASL shows features atypical of creole languages, such as agglutination, agglutinative morphology. ASL originated in the early 19th century in the American School for the Deaf (ASD) in West Hartford, Connecticut, from a situation of language contact. Since then, ASL use has been propagated w ...

Expression (sign Language)
In sign languages, expressions are the distinctive body postures and facial expressions that accompany signing, and which are necessary to properly form words. Expression is one of five components of a sign, along with handshape (), orientation (), location (), and movement (). A major component of expression is mouthing In sign language, mouthing is the production of visual syllables with the mouth while signing. That is, signers sometimes say or mouth a word in a spoken language at the same time as producing the sign for it. Mouthing is one of the many ways in w ....
