 note = {In this present work we describe in detail the trends of both vocal and phonemic confusion in response to distortions of band-eliminating nature. For tracing the finest phases and modes of confusion-characteristics as functions of distortion, it is important above all to have a full knowledge of the referential state of timbre-confusion in the normal condidion (no-cutting) and we take this as the point of beginning for our study.},
