Occlusives form a barrier/block on the surface of the skin keeping moisture from escaping. In phonetics, an occlusive (aka a stop or plosive) is a pulmonic consonant in which the vocal tract is closed or blocked off:
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.
A fricative is a consonant produced by forcing air through a narrow channel made by placing two articulators close together. These may be the lower lip against the upper teeth, in the case of ; the back of the tongue against the soft palate in the case of German ; or the side of the tongue against the molars, in the case of Welsh. This turbulent airflow is called frication.
In phonetics, a nasal, also called a nasal occlusive or nasal stop in contrast with an oral stop or nasalized consonant, is an occlusive consonant produced with a lowered velum, allowing air to escape freely through the nose. The vast majority of consonants are oral consonants. Examples of nasals in English are, and, in words such as nose, bring and mouth. Nasal occlusives are nearly universal in human languages. There are also other kinds of nasal consonants in some languages.
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 voiced velar plosive or stop is a type of consonantal sound used in many spoken languages.
The voiceless bilabial plosive or stop is a type of consonantal sound used in most spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨p⟩, and the equivalent X-SAMPA symbol is p.
The voiceless uvular plosive or stop is a type of consonantal sound, used in some spoken languages. It is pronounced like a voiceless velar plosive, except that the tongue makes contact not on the soft palate but on the uvula. The symbol in the International Phonetic Alphabet that represents this sound is ⟨q⟩, and the equivalent X-SAMPA symbol is q.
A voiced bilabial implosive is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɓ⟩, and the equivalent X-SAMPA symbol is b_<.
The voiced velar implosive is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɠ ⟩, and the equivalent X-SAMPA symbol is g_<. It is familiar to English speakers as the sound made when mimicking the 'gulping' of water.
In phonetics, a trill is a consonantal sound produced by vibrations between the active articulator and passive articulator. Standard Spanish ⟨rr⟩ as in perro, for example, is an alveolar trill.
In phonetics, nasalization is the production of a sound while the velum is lowered, so that some air escapes through the nose during the production of the sound by the mouth. An archetypal nasal sound is.
In phonetics and phonology, a bilabial stop is a type of consonantal sound, made with both lips, held tightly enough to block the passage of air. The most common sounds are the stops and, as in English pit and bit, and the voiced nasal. More generally, several kinds are distinguished:
Implosive consonants are a group of stop consonants with a mixed glottalic ingressive and pulmonic egressive airstream mechanism. That is, the airstream is controlled by moving the glottis downward in addition to expelling air from the lungs. Therefore, unlike the purely glottalic ejective consonants, implosives can be modified by phonation. Contrastive implosives are found in approximately 13% of the world's languages.
The voiced labial–velar plosive is a type of consonantal sound, used in some spoken languages. It is a and pronounced simultaneously. To make this sound, one can say go but with the lips closed as if one were saying Bo; the lips are to be released at the same time as or a fraction of a second after the g of go is pronounced. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɡ͡b⟩. Its voiceless counterpart is voiceless labial–velar plosive,.
The voiceless bilabial nasal is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨⟩, a combination of the letter for the voiced bilabial nasal and a diacritic indicating voicelessness. The equivalent X-SAMPA symbol is m_0.
The voiceless velar nasal is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ŋ̊⟩, a combination of the letter for the voiced velar nasal and a diacritic indicating voicelessness.. The equivalent X-SAMPA symbol is N_0.
In phonetics, an occlusive, sometimes known as a stop, is a consonant sound produced by occluding airflow in the vocal tract, but not necessarily in the nasal tract. The duration of the block is the occlusion of the consonant. An occlusive may refer to one or more of the following, depending on the author:
A voiceless velar implosive is a consonantal sound which is not used in any language. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɠ̊⟩ or ⟨kʼ↓⟩. A dedicated IPA letter, ⟨ƙ⟩, was withdrawn in 1993.
