Plosives

Manx has an optional process of lenition of plosives between vowels, whereby voiced plosives and voiceless fricatives become voiced fricatives and voiceless plosives become either voiced plosives or voiced fricatives.

A chart of the Tamil consonant phonemes in the International Phonetic Alphabet follows: The plosives have voiced allophones in predictable contexts.

An example of this relative spread can be seen in trying to explain why contrastive voicing commonly occurs with plosives, such as in English with “neat” and “need”, but much fewer have this occur in fricatives, such as the English “niece” and “knees”.

A series of alveolar plosives ranging from an open to a closed glottis phonation are: Additional diacritics are provided by the Extensions to the IPA for speech pathology.

Consonants There are three series of plosives or corresponding approximants: * Voiceless stops derive from their Latin counterparts in composition after another stop.

Earlier phases of Egyptian may have contrasted voiceless and voiced bilabial plosives, but the distinction seems to have been lost.

Hisses and pops are generated by the action of the tongue, lips and throat during sibilants and plosives.

It has also been suggested that the āytam was used to represent the voiced implosive (or closing part or the first half) of geminated voiced plosives inside a word.

Overall, voicing contrasts in fricatives are much rarer than in plosives, being found only in about a third of the world's languages as compared to 60 percent for plosive voicing contrasts.

Plosives (and, to some degree, fricatives ) modify the placement of formants in the surrounding vowels.

Plosives are never lateral—although they may have lateral release —and the distinction is meaningless for nasals and for consonants articulated in the throat.

Plosives are unvoiced if they occur word-initially or doubled.

Similarly, voiced plosives and affricates have become voiceless aspirates in the "even" tone and voiceless non-aspirates in others, another distinctive Mandarin development.

Some ad hoc letters have appeared in the literature for the retroflex lateral flap, the voiceless lateral fricatives, the epiglottal trill, and the labiodental plosives.

This phenomenon occurs because voiced fricatives have developed from lenition of plosives or fortition of approximants.

Thus 'b' and 'd' can rhyme (both being 'voiced plosives'), as can 'bh' and 'l' (which are both 'voiced continuants') but 'l', a 'voiced continuant', cannot rhyme with 'ph', a 'voiceless continuant'.

Voiced plosives details Traditionally, /b/ and /ɡ/ were not counted as Finnish phonemes, since they appear only in loanwords.

Whether they were plosives or fricatives at first is therefore not clear.
