Phonetic characteristics of double articulations in some Mangbutu-Efe languages

International audience This paper examines double articulations in three african languages: Mamvu, Lese and Efe, all belonging to the Central Sudanic language family. The phonetic inventory of these languagesexhibit some very interesting facts among which the most striking are voiceless labio-velars stops involving a trilled release and a labio-uvular stop which shows the combination of a voiceless and a voiced part in the same consonant. Acoustic and aerodynamic measurements describing the production of these sounds are presented.
