Accès au lexique et production de la parole: un survol

Abstract

Summary : Lexical access in speech production : A briefreview. This article provides a brief review of experimental and speech error data (in normal subjects and aphasic patients) concerned with lexical access in speech production. We start from the old distinction between two major processes involved in speech production, namely, lexical selection ofthe appropriate word from thousands of alternatives in the mental lexicon and phonological encoding of the corresponding word in order to compute its articulatory program. Then, we review data tracing the time-course of semantic and phonological activation, contrasting by the way two major and opposite conceptions of lexical access in speech production. The jirst view, called the two discrete stages theory is a modular view: there is no phonological encoding before lexical selection. The second view is a connectionist one: there is continuing interaction between the two processes. Finally, a reconciliation of modular and interactive accounts is proposed. Key words: speech production, modularity and connectionism, lexical access.
