Trilled affricate
In articulatory phonetics, trilled affricates, also known as post-trilled consonants, are consonants which begin as a stop and have a trill release. These consonants are reported to exist in some Northern Paman languages in Australia, as well as in some Chapacuran languages such Wariʼ language and Austronesian languages such as Fijian and Malagasy.
| Sound (voiceless) | IPA | Languages | Sound (voiced) | IPA | Languages |
|---|---|---|---|---|---|
| Voiceless trilled bilabial affricate | [pʙ̥] | Not attested in any natural language. | Voiced trilled bilabial affricate | [bʙ] | Kele and Avava. Only reported in an allophone of [mb] before [o] or [u] |
| Voiceless trilled alveolar affricate | [tr̥] | Ngkoth | Voiced trilled alveolar affricate | [dr] | Nias, Fijian and Avava also have this sound after [n]. |
| Voiceless epiglottal affricate | [ʡʜ] | Not attested in any natural language. | Voiced epiglottal affricate | [ʡʢ] | Hydaburg Haida. Cognate to Southern Haida [ɢ], Masset Haida [ʕ]. |
In Fijian, trilling is rare in these sounds, and they are frequently distinguished by being postalveolar. In Malagasy, they may have a rhotic release, [ʈɽ̝̊ ɳʈɽ̝̊ ɖɽ̝ ɳɖɽ̝], be simple stops, [ʈ ɳʈ ɖ ɳɖ], or standard affricates, [ʈʂ ɳʈʂ ɖʐ ɳɖʐ].
Most post-trilled consonants are affricates: the stop and trill share the same place of articulation. However, there is a rare exception in a few neighboring Amazonian languages, where a voiceless bilabially post-trilled dental stop, [t̪͡ʙ̥] (occasionally written [tᵖ]) is reported from Pirahã and from a few words in the Chapacuran languages Wariʼ and Oro Win. In the Chapacuran languages, [tʙ̥] is reported almost exclusively before rounded vowels such as [o] and [y].
Hydaburg Haida [ʡʢ] is cognate to Southern Haida [ɢ], Masset Haida [ʕ].
