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,^[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]	Namuyi	Voiced trilled bilabial affricate	[bʙ]	Kele and Avava. Only reported in an allophone of [mb] before [o] or [u], Namuyi
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, but may occur in Hydaburg Haida.	Voiced epiglottal affricate	[ʡʢ]	Hydaburg Haida. Possibly voiceless or a stop instead. Cognate to Southern Haida [ɢ], Masset Haida [ʕ].[2]

In Fijian, trilling is rare in these sounds, and they are frequently distinguished by being postalveolar.^[3] 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]. Sangtam contrasts [t͡ʙ] with aspirated [t͡ʙ̥ʰ]

Hydaburg Haida [ʡʢ] is cognate to Southern Haida [ɢ], Masset Haida [ʕ].^[2]
