The voiced velar lateral approximant is a type of consonantal sound, used as a distinct consonant in a very small number of spoken languages in the world. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʟ⟩ a small capital version of the Latin letter l, and the equivalent X-SAMPA symbol is L\.
The voiced alveolar lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents voiced dental, alveolar, and postalveolar lateral fricatives is ⟨ɮ⟩, and the equivalent X-SAMPA symbol is K\.
The voiceless bilabial fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɸ⟩, a Latinised form of the Greek letter Phi.
The voiceless dental non-sibilant fricative is a type of consonantal sound used in some spoken languages. It is familiar to English speakers as the 'th' in think. Though rather rare as a phoneme among the world's languages, it is encountered in some of the most widespread and influential ones. The symbol in the International Phonetic Alphabet that represents this sound is ⟨θ⟩, and the equivalent X-SAMPA symbol is T. The IPA symbol is the Greek letter theta, which is used for this sound in post-classical Greek, and the sound is thus often referred to as "theta".
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\.
The voiceless labial–velar fricative is a type of consonantal sound, used in spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʍ⟩. This was defined as a voiceless until 1979, when it was defined as a fricative with the place of articulation of the same way that is an approximant with the place of articulation of.
The voiceless pharyngeal fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is an h-bar, ⟨ħ⟩, and the equivalent X-SAMPA symbol is X\. In the transcription of Arabic, Berber as well as a few other scripts, it is often written ⟨Ḥ⟩, ⟨ḥ⟩.
A voiceless postalveolar fricative is a type of consonantal sound used in some spoken languages. The International Phonetic Association uses the term voiceless postalveolar fricative only for the sound, but it also describes the voiceless postalveolar non-sibilant fricative, for which there are significant perceptual differences.
The voiceless retroflex sibilant fricative is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʂ⟩ which is a Latin letter s combined with a retroflex hook. Like all the retroflex consonants, the IPA letter is formed by adding a rightward-pointing hook to the bottom of ⟨s⟩. A distinction can be made between laminal, apical, and sub-apical articulations. Only one language, Toda, appears to have more than one voiceless retroflex sibilant, and it distinguishes subapical palatal from apical postalveolar retroflex sibilants; that is, both the tongue articulation and the place of contact on the roof of the mouth are different.
The voiceless retroflex lateral fricative is a type of consonantal sound, used in some spoken languages. The 'implicit' IPA letter for this sound, ⟨ꞎ ⟩, is overtly supported by the extIPA.
The voiceless palatal lateral fricative is a type of consonantal sound, used in a few spoken languages.
Bidental consonants are consonants articulated with both the lower and upper teeth. They are normally found only in speech pathology, and are distinct from interdental consonants such as, which involve the tongue articulated between the teeth rather than the teeth themselves. The diacritic for bidental consonants in the extensions to the IPA is the same superscript plus subscript bridge, ⟨◌̪͆⟩. This is used for sounds most commonly found in disordered speech:
The voiceless retroflex sibilant affricate is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨t̠͡ʂ⟩, sometimes simplified to ⟨tʂ⟩ or ⟨ꭧ⟩, and the equivalent X-SAMPA symbol is ts`. Its apical variant is ⟨ʈ̺͡ʂ̺⟩ and laminal variant ⟨ʈ̻͡ʂ̻⟩.
The voiced epiglottal or pharyngeal tap or flap is not known to exist as a phoneme in any language. However, it exists as the intervocalic voiced allophone of the otherwise voiceless epiglottal stop of Dahalo and perhaps of other languages. It may also exist in Iraqi Arabic, where the consonant 'ayn is too short to be an epiglottal stop, but has too much of a burst to be a fricative or approximant.
The voiceless alveolar trill differs from the voiced alveolar trill only by the vibrations of the vocal cord. It occurs in a few languages, usually alongside the voiced version, as a similar phoneme or an allophone.
The alveolar lateral ejective fricative is a type of consonantal sound, reported in the Northwest Caucasian languages and in Modern South Arabian languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɬʼ⟩.
The voiceless retroflex nasal is an extremely rare type of consonantal sound, used in very few spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɳ̊⟩, a combination of the letter for the voiced retroflex nasal and a diacritic indicating voicelessness.
The voiceless alveolar tap or flap is rare as a phoneme. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɾ̥⟩, a combination of the letter for the voiced alveolar tap/flap and a diacritic indicating voicelessness. The equivalent X-SAMPA symbol is 4_0.
The voiced palatal lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʎ̝⟩, though in extIPA ⟨𝼆̬⟩ is preferred. The equivalent X-SAMPA symbol is L_r.
The voiceless labial–palatal fricative or approximant is a type of consonantal sound, used in a few spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɥ̊⟩ or ⟨ɸ͡ç⟩. The former – more accurately the voiceless labialized palatal fricative by those who consider it to be a fricative – is the voiceless counterpart of the voiced labial–palatal approximant. Other linguists posit voiceless approximants distinct from voiceless fricatives; to them, is a voiceless labialized palatal approximant.
