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,[1] 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], Namuyi[2] |
| 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].[3] |
In Fijian, trilling is rare in these sounds, and they are frequently distinguished by being postalveolar.[4] 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].
