This document discusses the process of speech production from conceptualization to articulation. It summarizes some key models and findings from psycholinguistic research. The production process begins with conceptualization of a message in the mind. Levelt's model describes how concepts are formulated into linguistic units and encoded for motor production. Speech errors provide insights into the formulation process. Articulation involves coordinated movements of the vocal tract controlled by motor planning and cycles of production. Speakers self-monitor their speech through internal feedback loops and often self-correct mistakes. Research on sign language also informs understanding of the independence of cognitive and physical aspects of language production.
