Nouvelle contribution à la théorie des «locus»

Abstract

Abstract Johansson’s experiments reveal that /d/ is identified mostly thanks to its transitions, in opposition to /b/ and /g/, a consideration which sustains the author’s opinion. By means of EVA III, he first synthesized /da/ and /du/ after DELATTREs rules, then after natural patterns. The latter turn out to be quite more intelligible, a consideration which shows that the extrapolated ‘loci’ which Delattre had to use in order to avoid categorization confusions, are not able to ensure ‘maximal’ consonantic perception; his experiments must have been altered by confusion between ‘transitions’ and ‘sonorous attacks’. The author considers logatoms as ‘aggregate patterns’, tackles formantic anamorphosis and ‘balance’, and gives notice of the realization of an ‘evagraphic dictionary’ intended for computer speech.
