Approximants are speech sounds that involve the articulators approaching each other but not narrowly enough nor with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no turbulence. This class is composed of sounds like and semivowels like and, as well as lateral approximants like.
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. However, these paralinguistic sounds in English are not full click consonants, as they only involve the front of the tongue, without the release of the back of the tongue that is required for clicks to combine with vowels and form syllables.
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 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.
In phonetics, a plosive, also known as an occlusive or simply a stop, is a pulmonic consonant in which the vocal tract is blocked so that all airflow ceases.
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.
The voiced velar nasal, also known as agma, from the Greek word for 'fragment', is a type of consonantal sound used in some spoken languages. It is the sound of ng in English sing as well as n before velar consonants as in English and ink. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ŋ⟩, and the equivalent X-SAMPA symbol is N. The IPA symbol ⟨ŋ⟩ is similar to ⟨ɳ⟩, the symbol for the retroflex nasal, which has a rightward-pointing hook extending from the bottom of the right stem, and to ⟨ɲ⟩, the symbol for the palatal nasal, which has a leftward-pointing hook extending from the bottom of the left stem. Both the IPA symbol and the sound are commonly called 'eng' or 'engma'.
A retroflex, apico-domal, or cacuminalconsonant is a coronal consonant where the tongue has a flat, concave, or even curled shape, and is articulated between the alveolar ridge and the hard palate. They are sometimes referred to as cerebral consonants—especially in Indology.
The voiced bilabial trill is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents the sound is ⟨ʙ⟩, a small capital version of the Latin letter b, and the equivalent X-SAMPA symbol is B\.
The voiced retroflex nasal is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɳ ⟩, and the equivalent X-SAMPA symbol is n`.
The voiced uvular nasal is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɴ⟩, a small capital version of the Latin letter n; the equivalent X-SAMPA symbol is N\.
The voiced epiglottal or pharyngeal trill, or voiced epiglottal fricative, is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʢ⟩.
The voiced uvular plosive or stop is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɢ⟩, a small capital version of the Latin letter g, and the equivalent X-SAMPA symbol is G\.
The voiceless epiglottal or pharyngeal trill, or voiceless epiglottal fricative, is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʜ⟩, a small capital version of the Latin letter h, and the equivalent X-SAMPA symbol is H\.
In phonetics, a flap or tap is a type of consonantal sound, which is produced with a single contraction of the muscles so that one articulator is thrown against another.
Linguolabials or apicolabials are consonants articulated by placing the tongue tip or blade against the upper lip, which is drawn downward to meet the tongue. They represent one extreme of a coronal articulatory continuum which extends from linguolabial to subapical palatal places of articulation. Cross-linguistically, linguolabial consonants are very rare. They are found in a cluster of languages in Vanuatu, in the Kajoko dialect of Bijago in Guinea-Bissau, in Umotína, and as paralinguistic sounds elsewhere. They are also relatively common in disordered speech, and the diacritic is specifically provided for in the extensions to the IPA.
The voiceless labiodental plosive or stop is a consonant sound produced like a [p], but with the lower lip contacting the upper teeth, as in [f]. This can be represented in the IPA as ⟨p̪⟩. A separate symbol not recognized by the IPA that was occasionally seen, especially in Bantu linguistics, is the qp ligature⟨ȹ⟩.
In linguistics, pre-stopping, also known as pre-occlusion or pre-plosion, is a phonological process involving the historical or allophonic insertion of a very short stop consonant before a sonorant, such as a short before a nasal or a lateral, or a short before a nasal. The resulting sounds are called pre-stopped consonants, or sometimes pre-ploded or pre-occluded consonants, although technically may be considered an occlusive/stop without the pre-occlusion.
Palatals 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.
