Christopher J. Markiewicz, Jason W. Bohland
2016 NeuroImage  
Speech repetition relies on a series of distributed cortical representations and functional pathways.  ...  A speaker must map auditory representations of incoming sounds onto learned speech items, maintain an accurate representation of those items in short-term memory, interface that representation with the  ...  a Speech Sound Map 33 .  ...

Enhanced neural synchrony between left auditory and premotor cortex is associated with successful phonetic categorization

Jussi Alho, Fa-Hsuan Lin, Marc Sato, Hannu Tiitinen, Mikko Sams, Iiro P. Jääskeläinen
2014 Frontiers in Psychology  
The cortical dorsal auditory stream has been proposed to mediate mapping between auditory and articulatory-motor representations in speech processing.  ...  Here, magnetoencephalography was used to examine connectivity between auditory and motor areas while subjects were performing a sensorimotor task involving speech sound identification and overt repetition  ...  The overt imitation task differed from the overt repetition in that the reproduction of the target syllable was to be done by imitating the pitch of the stimulus sound.  ...

Motor cortex maps articulatory features of speech sounds

F. Pulvermuller, M. Huss, F. Kherif, F. Moscoso del Prado Martin, O. Hauk, Y. Shtyrov
2006 Proceedings of the National Academy of Sciences of the United States of America  
In localizer experiments, subjects had to silently articulate the same syllables and, in a second task, move their lips or tongue. Speech perception most strongly activated superior temporal cortex.  ...  For example, the direct realist theory of speech perception (17, 18) postulates a link between motor and perceptual representations of speech.  ...  Echo-planar imaging (EPI) was applied with a repetition time of 3.2 s in the speech-perception task (1.6 s of scanning and 1.6 s of silent gap) and 1.6 s in the motor and articulation-localizer tasks.  ...

Dorsal and ventral streams: a framework for understanding aspects of the functional anatomy of language

Gregory Hickok, David Poeppel
2004 Cognition  
This cortical processing system then diverges into two broad processing streams, a ventral stream, which is involved in mapping sound onto meaning, and a dorsal stream, which is involved in mapping sound  ...  The ventral stream projects ventro-laterally toward inferior posterior temporal cortex (posterior middle temporal gyrus) which serves as an interface between sound-based representations of speech in the  ...  same input onto a motorarticulatory representation (as in a repetition task).  ...

Neural modeling and imaging of the cortical interactions underlying syllable production

Frank H. Guenther, Satrajit S. Ghosh, Jason A. Tourville
2006 Brain and Language  
This paper describes a neural model of speech acquisition and production that accounts for a wide range of acoustic, kinematic, and neuroimaging data concerning the control of speech movements.  ...  The model is a neural network whose components correspond to regions of the cerebral cortex and cerebellum, including premotor, motor, auditory, and somatosensory cortical areas.  ...  sound is represented by a single speech sound map cell in the model, it is expected that premotor cortex sound maps in the brain involve distributed representations of each speech sound.  ...

Cortical interactions underlying the production of speech sounds

Frank H. Guenther
2006 Journal of Communication Disorders  
New speech sounds are learned by first storing an auditory target for the sound, then using the auditory feedback control system to control production of the sound in early repetitions.  ...  This article describes a model of speech motor control in which a feedforward control system, involving premotor and primary motor cortex and the cerebellum, works in concert with auditory and somatosensory  ...  The author thanks Jason Tourville for his assistance in preparing this article.  ...
