Sensorimotor impairment of speech auditory feedback processing in aphasia

Altered processing of sensorimotor feedback in schizophrenia.

Schizophrenia is characterized by an altered sense of the reality, associated with hallucinations and delusions. Some theories suggest that schizophrenia is related to a deficiency of the system that generates information about the sensory consequences of the actions realized by the subject. This system monitors the reafferent information resulting from an action and allows its anticipation. In...

Auditory visual speech processing

This paper provides an overview of the developments in Auditory Visual Speech Processing, a Special Interest Group within Eurospeech. I hope that this discussion will be informative and useful to readers in a variety of fields, including psychology, speech science, animation, psycholinguistics, human-machine interaction, hearingimpaired communication, and numerous other fields which also share ...

Delayed auditory feedback simulates features of nonfluent primary progressive aphasia

The pathophysiology of nonfluent primary progressive aphasia (nfvPPA) remains poorly understood. Here, we compared quantitatively speech parameters in patients with nfvPPA versus healthy older individuals under altered auditory feedback, which has been shown to modulate normal speech output. Patients (n=15) and healthy volunteers (n=17) were recorded while reading aloud under delayed auditory f...

Auditory Neural Processing of Speech

Recordings from single auditory neurons in response to speech and speech-like stimuli provide detailed descriptions of neural processing in the earliest stages of speech perception. These studies show that a great deal of information about both the formant pattern and voice pitch is available in both the average discharge rates and the temporal discharge patterns of auditory-nerve fibers and co...
