Articulating: the neural mechanisms of speech production

E Kearney, FH Guenther - Language, Cognition and Neuroscience, 2019 - Taylor & Francis
Speech production is a highly complex sensorimotor task involving tightly coordinated
processing across large expanses of the cerebral cortex. Historically, the study of the neural …

To lump or to split? Possible subtypes of apraxia of speech

ML Mailend, E Maas - Aphasiology, 2021 - Taylor & Francis
Background The speculation that apraxia of speech (AOS) is not a unitary diagnosis, but
consists of different subtypes instead, has been around for decades. However, attempts to …

How to cut the pie is no piece of cake: toward a process‐oriented approach to assessment and diagnosis of speech sound disorders

M Littlejohn, E Maas - International Journal of Language & …, 2023 - Wiley Online Library
