A chereme, as the basic unit of signed communication, is functionally and psychologically equivalent to the phonemes of oral languages, and has been replaced by that term in the academic literature. Cherology, as the study of cheremes in language, is thus equivalent to phonology. The terms are not in use anymore.
Sound is defined as "(a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation.
Phonology is the branch of linguistics that studies how languages systematically organize their phonemes or, for sign languages, their constituent parts of signs.The term can also refer specifically to the sound or sign system of a particular language variety.
A phone is a speech segment that possesses distinct physical or perceptual properties and serves as the basic unit of phonetic speech analysis. Phones are generally either vowels or consonants . A phonetic transcription (based on phones) is enclosed within square brackets ( [ ] ), rather than the slashes ( / / ) of a phonemic transcription ...
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 [+voice] distinguishes the two bilabial plosives: [p] and [b] (i.e., it makes the two plosives distinct from one another).
The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz. [2] [3] [4] In air at atmospheric pressure, these represent sound waves with wavelengths of 17 metres (56 ft) to 1.7
A lexical set is a group of words that share a particular vowel or consonant sound. A phoneme is a basic unit of sound in a language that can distinguish one word from another. Most commonly, following the work of phonetician John C. Wells , a lexical set is a class of words in a language that share a certain vowel phoneme .
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.
