Articulation score

Last updated

In telecommunication, an articulation score (AS) is a subjective measure of the intelligibility of a voice system in terms of the percentage of words correctly understood over a channel perturbed by interference.

Telecommunication transmission of information between locations using electromagnetics

Telecommunication is the transmission of signs, signals, messages, words, writings, images and sounds or information of any nature by wire, radio, optical or other electromagnetic systems. Telecommunication occurs when the exchange of information between communication participants includes the use of technology. It is transmitted either electrically over physical media, such as cables, or via electromagnetic radiation. Such transmission paths are often divided into communication channels which afford the advantages of multiplexing. Since the Latin term communicatio is considered the social process of information exchange, the term telecommunications is often used in its plural form because it involves many different technologies.

In speech communication, intelligibility is a measure of how comprehensible speech is in given conditions. Intelligibility is affected by the level and quality of the speech signal, the type and level of background noise, reverberation, and, for speech over communication devices, the properties of the communication system. A common standard measurement for the quality of the intelligibility of speech is the Speech Transmission Index (STI). The concept of speech intelligibility is relevant to several fields, including phonetics, human factors, acoustical engineering, and audiometry.

A system is a group of interacting or interrelated entities that form a unified whole. A system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.

Articulation scores have been experimentally obtained as functions of varying word content, bandwidth, audio signal-to-noise ratio and the experience of the talkers and listeners involved.

In linguistics, a word is the smallest element that can be uttered in isolation with objective or practical meaning.

Bandwidth (signal processing) difference between the upper and lower frequencies in a continuous set of frequencies

Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies. It is typically measured in hertz, and depending on context, may specifically refer to passband bandwidth or baseband bandwidth. Passband bandwidth is the difference between the upper and lower cutoff frequencies of, for example, a band-pass filter, a communication channel, or a signal spectrum. Baseband bandwidth applies to a low-pass filter or baseband signal; the bandwidth is equal to its upper cutoff frequency.

Signal-to-noise ratio is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels. A ratio higher than 1:1 indicates more signal than noise.

Click consonants, or clicks, are speech sounds that occur as consonants in many languages of Southern Africa and in three languages of East Africa. Examples familiar to English-speakers are the Tut-tut or Tsk! Tsk! used to express disapproval or pity, the tchick! used to spur on a horse, and the clip-clop! sound children make with their tongue to imitate a horse trotting.

Manner of articulation configuration and interaction of the articulators when making a speech sound

In articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators when making a speech sound. One parameter of manner is stricture, that is, how closely the speech organs approach one another. Others include those involved in the r-like sounds, and the sibilancy of fricatives.

Phonetics is a branch of linguistics that studies the sounds of human speech, or—in the case of sign languages—the equivalent aspects of sign. It is concerned with the physical properties of speech sounds or signs (phones): their physiological production, acoustic properties, auditory perception, and neurophysiological status. Phonology, on the other hand, is concerned with the abstract, grammatical characterization of systems of sounds or signs.

Place of articulation Place in the mouth consonants are articulated

In articulatory phonetics, the place of articulation of a consonant is the point of contact where an obstruction occurs in the vocal tract between an articulatory gesture, an active articulator, and a passive location. Along with the manner of articulation and the phonation, it gives the consonant its distinctive sound.

Velars are consonants articulated with the back part of the tongue against the soft palate, the back part of the roof of the mouth.

Coronal consonants are consonants articulated with the flexible front part of the tongue. Among places of articulation, only the coronal consonants can be divided into as many articulation types: apical, laminal, domed, or subapical as well as different postalveolar articulations : palato-alveolar, alveolo-palatal and retroflex. Only the front of the tongue (coronal) has such dexterity among the major places of articulation, allowing such variety of distinctions. Coronals have another dimension, grooved, to make sibilants in combination with the orientations above.

Alveolar consonant consonants articulated with the tongue against or close to the superior alveolar ridge

Alveolar consonants are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli of the superior teeth. Alveolar consonants may be articulated with the tip of the tongue, as in English, or with the flat of the tongue just above the tip, as in French and Spanish. The laminal alveolar articulation is often mistakenly called dental, because the tip of the tongue can be seen near to or touching the teeth. However, it is the rearmost point of contact that defines the place of articulation; this is where the oral cavity ends, and it is the resonant space of the oral cavity that gives consonants and vowels their characteristics. The International Phonetic Alphabet (IPA) does not have separate symbols for the alveolar consonants. Rather, the same symbol is used for all coronal places of articulation that are not palatalized like English palato-alveolar sh, or retroflex. To disambiguate, the bridge may be used for a dental consonant, or the under-bar may be used for the postalveolars. Note that differs from dental in that the former is a sibilant and the latter is not. differs from postalveolar in being unpalatalized. The bare letters, etc. cannot be assumed to specifically represent alveolars. The language may not make such distinctions, such that two or more coronal places of articulation are found allophonically, or the transcription may simply be too broad to distinguish dental from alveolar. If it is necessary to specify a consonant as alveolar, a diacritic from the Extended IPA may be used:, etc., though that could also mean extra-retracted. The letters ⟨s, t, n, l⟩ are frequently called 'alveolar', and the language examples below are all alveolar sounds.

Glottal consonants are consonants using the glottis as their primary articulation. Many phoneticians consider them, or at least the glottal fricative, to be transitional states of the glottis without a point of articulation as other consonants have, while some do not consider them to be consonants at all. However, glottal consonants behave as typical consonants in many languages. For example, in Literary Arabic, most words are formed from a root C-C-C consisting of three consonants, which are inserted into templates such as or. The glottal consonants and can occupy any of the three root consonant slots, just like "normal" consonants such as or.

Joint location at which two or more bones make contact

A joint or articulation is the connection made between bones in the body which link the skeletal system into a functional whole. They are constructed to allow for different degrees and types of movement. Some joints, such as the knee, elbow, and shoulder, are self-lubricating, almost frictionless, and are able to withstand compression and maintain heavy loads while still executing smooth and precise movements. Other joints such as sutures between the bones of the skull permit very little movement in order to protect the brain and the sense organs. The connection between a tooth and the jawbone is also called a joint, and is described as a fibrous joint known as a gomphosis. Joints are classified both structurally and functionally.

Postalveolar consonants are consonants articulated with the tongue near or touching the back of the alveolar ridge, farther back in the mouth than the alveolar consonants, which are at the ridge itself but not as far back as the hard palate, the place of articulation for palatal consonants. Examples of postalveolar consonants are the English palato-alveolar consonants, as in the words "ship", "'chill", "vision", and "jump", respectively.

Voiced fricatives produced in the postalveolar region include the voiced palato-alveolar fricative, the voiced postalveolar non-sibilant fricative, the voiced retroflex fricative, and the voiced alveolo-palatal fricative. This article discusses the first two.

Pharyngeal consonant Consonant articulated through the pharynx

A pharyngeal consonant is a consonant that is articulated primarily in the pharynx. Some phoneticians distinguish upper pharyngeal consonants, or "high" pharyngeals, pronounced by retracting the root of the tongue in the mid to upper pharynx, from (ary)epiglottal consonants, or "low" pharyngeals, which are articulated with the aryepiglottic folds against the epiglottis in the lower larynx, as well as from epiglotto-pharyngeal consonants, with both movements being combined.

In music, an accent is an emphasis, stress, or stronger attack placed on a particular note or set of notes, or chord, either as a result of its context or specifically indicated by an accent mark. Accents contribute to the articulation and prosody of a performance of a musical phrase. Accents may be written into a score or part by a composer or added by the performer as part of his or her interpretation of a musical piece. By default, in the music notation program Sibelius, "accents boost the dynamic by 50%."

Articulation may refer to:

Co-articulated consonants or complex consonants are consonants produced with two simultaneous places of articulation. They may be divided into two classes: doubly articulated consonants with two primary places of articulation of the same manner, and consonants with secondary articulation, that is, a second articulation not of the same manner.

In music, articulation is the direction or performance technique which affects the transition or continuity on a single note or between multiple notes or sounds. Articulation involves subtle differences within duration, amplitude, meter, and, through techniques such as tremolo and pitch.

Tonguing is a technique used with wind instruments to enunciate different notes using the tongue on the reed or woodwind mouthpiece or brass mouthpiece. A silent "tee" is made when the tongue strikes the reed or roof of the mouth causing a slight breach in the air flow through the instrument. If a more soft tone is desired, the syllable "da" is preferred. The technique also works for whistling. Tonguing also refers to articulation, which is how a musician begins the note and how the note is released For wind players, articulation is commonly spoken of in terms of tonguing because the tongue is used to stop and allow air to flow in the mouth. Tonguing does not apply to non wind instruments, but articulation does apply to all instruments.

Palatal consonants are consonants articulated with the body of the tongue raised against the hard palate. Consonants with the tip of the tongue curled back against the palate are called retroflex.

The linguolabial fricative is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents it is ⟨ð̼⟩ or ⟨β̺⟩.

The voiced retroflex lateral fricative is a type of consonantal sound. The IPA has no symbol for this sound.
