Tongue Shape
In linguistics, specifically articulatory phonetics, tongue shape describes the shape that the tongue assumes when it makes a sound. Because the sibilant sounds have such a high perceptual prominence, tongue shape is particularly important; small changes in tongue shape are easily audible and can be used to produce different speech sounds, even within a given language. For non-sibilant sounds, the relevant variations in tongue shape can be adequately described by the concept of secondary articulation, in particular palatalization (raising of the middle of the tongue), velarization (raising of the back of the tongue) and pharyngealization (retracting of the root of the tongue). Usually, only one secondary articulation can occur for a given sound. In addition, the acoustic quality of velarization and pharyngealization is very similar so no language contrasts the two. Shape distinctions The following varieties of tongue shapes are defined for sibilants, from sharpest and highest-p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hushing Consonant
Sibilants are fricative consonants of higher amplitude and pitch, made by directing a stream of air with the tongue towards the teeth. Examples of sibilants are the consonants at the beginning of the English words ''sip'', ''zip'', ''ship'', and ''genre''. The symbols in the International Phonetic Alphabet used to denote the sibilant sounds in these words are, respectively, . Sibilants have a characteristically intense sound, which accounts for their paralinguistic use in getting one's attention (e.g. calling someone using "psst!" or quieting someone using "shhhh!"). In the hissing sibilants and , the back of the tongue forms a narrow channel (is '' grooved'') to focus the stream of air more intensely, resulting in a high pitch. With the hushing sibilants (occasionally termed ''shibilants''), such as English , , , and , the tongue is flatter, and the resulting pitch lower. A broader category is stridents, which include more fricatives than sibilants such as uvulars. Because al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonetics
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 modali ...

Human Voice
The human voice consists of sound made by a human being using the vocal tract, including talking, singing, laughing, crying, screaming, shouting, humming or yelling. The human voice frequency is specifically a part of human sound production in which the vocal folds (vocal cords) are the primary sound source. (Other sound production mechanisms produced from the same general area of the body involve the production of unvoiced consonants, clicks, whistling and whispering.) Generally speaking, the mechanism for generating the human voice can be subdivided into three parts; the lungs, the vocal folds within the larynx (voice box), and the articulators. The lungs, the "pump" must produce adequate airflow and air pressure to vibrate vocal folds. The vocal folds (vocal cords) then vibrate to use airflow from the lungs to create audible pulses that form the laryngeal sound source. The muscles of the larynx adjust the length and tension of the vocal folds to 'fine-tune' pitch and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vocal Tract
The vocal tract is the cavity in human bodies and in animals where the sound produced at the sound source (larynx in mammals; syrinx (biology), syrinx in birds) is filtered. In birds it consists of the Vertebrate trachea, trachea, the Syrinx (biology), syrinx, the oral cavity, the upper part of the esophagus, and the beak. In mammals it consists of the laryngeal cavity, the pharynx, the oral cavity, and the nasal cavity. The estimated average length of the vocal tract in adult male humans is 16.9 cm and 14.1 cm in adult females.

Relative Articulation
In phonetics and phonology, relative articulation is description of the manner and place of articulation of a speech sound relative to some reference point. Typically, the comparison is made with a default, unmarked articulation of the same phoneme in a neutral sound environment. For example, the English velar consonant is ''fronted'' before the vowel (as in ''keep'') compared to articulation of before other vowels (as in ''cool''). This fronting is called palatalization. The relative position of a sound may be described as ''advanced'' (''fronted''), ''retracted'' (''backed''), ''raised'', ''lowered'', ''centralized'', or ''mid-centralized''. The latter two terms are only used with vowels, and are marked in the International Phonetic Alphabet with diacritics over the vowel letter. The others are used with both consonants and vowels, and are marked with iconic diacritics under the letter. Another dimension of relative articulation that has IPA diacritics is the degree of ro ...

Airstream Mechanism
In phonetics, the airstream mechanism is the method by which airflow is created in the vocal tract. Along with phonation and articulation, it is one of three main components of speech production. The airstream mechanism is mandatory for sound production and constitutes the first part of this process, which is called initiation. The organ generating the airstream is called the ''initiator'' and there are three initiators used in spoken human languages: * the diaphragm together with the ribs and lungs ''(pulmonic'' mechanisms), * the glottis ''(glottalic'' mechanisms), and * the tongue ''(lingual'' or ''"velaric"'' mechanisms). Though not used in any language, the cheeks may be used to generate the airstream ''(buccal'' mechanism, notated in VoQS). See buccal speech. After a laryngectomy, the esophagus may be used as the initiator (notated for simple esophageal speech and for tracheo-esophageal speech in VoQS). See esophageal speech.

Phonation
The term phonation has slightly different meanings depending on the subfield of phonetics. Among some phoneticians, ''phonation'' is the process by which the vocal folds produce certain sounds through quasi-periodic vibration. This is the definition used among those who study laryngeal anatomy and physiology and speech production in general. Phoneticians in other subfields, such as linguistic phonetics, call this process '' voicing'', and use the term ''phonation'' to refer to any oscillatory state of any part of the larynx that modifies the airstream, of which voicing is just one example. Voiceless and supra-glottal phonations are included under this definition. Voicing The phonatory process, or voicing, occurs when air is expelled from the lungs through the glottis, creating a pressure drop across the larynx. When this drop becomes sufficiently large, the vocal folds start to oscillate. The minimum pressure drop required to achieve phonation is called the phonation threshold ...

Manner Of Articulation
In articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators (speech organs such as the tongue, lips, and palate) 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 rhotic consonant, r-like sounds (flap consonant, taps and trill consonant, trills), and the sibilant, sibilancy of fricative consonant, fricatives. The concept of manner is mainly used in the discussion of consonants, although the movement of the articulators will also greatly alter the resonant properties of the vocal tract, thereby changing the formant structure of speech sounds that is crucial for the identification of vowels. For consonants, the place of articulation and the degree of phonation of voicing are considered separately from manner, as being independent parameters. Homorganic consonants, which have the same place of articulation, may have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Place Of Articulation
In articulatory phonetics, the place of articulation (also point 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. Since vowels are produced with an open vocal tract, the point where their production occurs cannot be easily determined. Therefore, they are not described in terms of a place of articulation but by the relative positions in vowel space. This is mostly dependent on their formant frequencies and less on the specific tongue position and lip rounding. The terminology used in describing place ...
