Abstract

This article outlines the main stages of speech production and inventories the types of errors that can disrupt oral communication, drawing on psycholinguistic research, particularly Eric Keller. It emphasizes that speaking—although seemingly effortless and continuous—relies on complex operations: message conceptualization, lexical selection, semantic and syntactic encoding, phonological and morphological encoding, and articulation. The paper reviews common error types (stuttering, repetitions, pauses, slips of the tongue) and discusses their effects on message transmission. It also shows how such errors provide useful evidence for understanding the organization of the mental lexicon and the mechanisms underlying language processing.
