Articulatory variability and speech errors: An overview

This paper presents an overview of a series of studies exploring the link between articulatory variability and speech errors in repetitive speech. The results from these articulatory speech error studies challenged the existence of phonemic speech errors and the findings necessitated a different approach of how errors should be interpreted. The objective of the paper is to evaluate how several researchers analyzed and interpreted the error data and summarizes several important findings with respect to the behavior and appearance of errors. Several psycholinguistic models are discussed that have been used to explain patterns of errors, including the cascading activation model and Articulatory Phonology.
