Аннотация:This paper presents a pilot instrumental study of phonetic reduction of noun class suffi xes in Akebu (Kwa, Ghana-Togo mountain, West Africa). Noun class suffi xes starting with a glide are regularly perceived as omitted or almost omitted, and therefore full and reduced variants can be distinguished for such nouns. A formant measurement of fi nal parts of full and reduced forms of the same nouns has shown that, fi rst, for a given fi nal part of a noun stem the reduced variant is phonetically close to the corresponding full variant and, second, for a given final part of a noun stem the forms with reduction of different suffixes are phonetically different.
