The purpose of this article is to introduce three psycholinguistic models of speech production: the Levelt Model, the Interactive Activation Model of G. Dell and the Independent Network Model of A. Caramazza. The architecture of the models and the processes they assume are described and compared. The models differ both in the data on which their authors base their claims, and also in some crucial assumptions like succession of activation of the three basic networks of speech production (semantic, grammatical and phonological), the mechanisms of selection of the individual units within these networks and the presence or absence of feedback between them, etc.
