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 at the entrance of the larynx, as well as from epiglotto-pharyngeal consonants, with both movements being combined. Stops and trills can be reliably produced only at the epiglottis, and fricatives can be reliably produced only in the upper pharynx. When they are treated as distinct places of articulation, the term radical consonant may be used as a cover term, or the term guttural consonants may be used instead. Pharyngeal consonants can trigger effects on neighboring vowels. Instead of uvulars, which nearly always trigger retraction, pharyngeals tend to trigger lowering. For example, in Moroccan Arabic, pharyngeals tend to lower neighboring vowels (corresponding to the formant 1). Meanwhile, in Chechen, it causes lowering as well, in addition to centralization and lengthening of the segment /a/. In addition, consonants and vowels may be secondarily pharyngealized. Also, strident vowels are defined by an accompanying epiglottal trill.

Pharyngeal consonants in the IPA

Pharyngeal/epiglottal consonants in the International Phonetic Alphabet (IPA): The Hydaburg dialect of Haida has a trilled epiglottal and a trilled epiglottal affricate ~. (There is some voicing in all Haida affricates, but it is analyzed as an effect of the vowel.) For transcribing disordered speech, the extIPA provides symbols for upper-pharyngeal stops, ⟨⟩ and ⟨⟩.

Place of articulation

The IPA first distinguished epiglottal consonants in 1989, with a contrast between pharyngeal and epiglottal fricatives, but advances in laryngoscopy since then have caused specialists to re-evaluate their position. Since a trill can be made only in the pharynx with the aryepiglottic folds (in the pharyngeal trill of the northern dialect of Haida, for example), and incomplete constriction at the epiglottis, as would be required to produce epiglottal fricatives, generally results in trilling, there is no contrast between (upper) pharyngeal and epiglottal based solely on place of articulation. Esling (2010) thus restores a unitary pharyngeal place of articulation, with the consonants being described by the IPA as epiglottal fricatives differing from pharyngeal fricatives in their manner of articulation rather than in their place: "The so-called 'Epiglottal fricatives' are represented [here] as pharyngeal trills,, since the place of articulation is identical to, but trilling of the aryepiglottic folds is more likely to occur in tighter settings of the laryngeal constrictor or with more forceful airflow. The same 'epiglottal' symbols could represent pharyngeal fricatives that have a higher larynx position than , but a higher larynx position is also more likely to induce trilling than in a pharyngeal fricative with a lowered larynx position. Because and occur at the same Pharyngeal/Epiglottal place of articulation (Esling, 1999), the logical phonetic distinction to make between them is in manner of articulation, trill versus fricative." Edmondson et al. distinguish several subtypes of pharyngeal consonant. Pharyngeal or epiglottal stops and trills are usually produced by contracting the aryepiglottic folds of the larynx against the epiglottis. That articulation has been distinguished as aryepiglottal. In pharyngeal fricatives, the root of the tongue is retracted against the back wall of the pharynx. In a few languages, such as Achumawi, Amis of Taiwan and perhaps some of the Salishan languages, the two movements are combined, with the aryepiglottic folds and epiglottis brought together and retracted against the pharyngeal wall, an articulation that has been termed epiglotto-pharyngeal. The IPA does not have diacritics to distinguish this articulation from standard aryepiglottals; Edmondson et al. use the ad hoc, somewhat misleading, transcriptions ⟨ʕ͡ʡ⟩ and ⟨ʜ͡ħ⟩. There are, however, several diacritics for subtypes of pharyngeal sound among the Voice Quality Symbols. Although upper-pharyngeal plosives are not found in the world's languages, apart from the rear closure of some click consonants, they occur in disordered speech. See voiceless upper-pharyngeal plosive and voiced upper-pharyngeal plosive.

Distribution

Pharyngeals are known primarily from three areas of the world: There are scattered reports of pharyngeals elsewhere, as in: The fricatives and trills (the pharyngeal and epiglottal fricatives) are frequently conflated with pharyngeal fricatives in literature. That was the case for Dahalo and Northern Haida, for example, and it is likely to be true for many other languages. The distinction between these sounds was recognized by IPA only in 1989, and it was little investigated until the 1990s.
