Human speech perception is a paradigm example of the complexity of human linguistic processing; however, it is also the dominant way of expressing vocal identity and is critically important for social interactions. Here, I review the ways that the speech, the talker, and the social nature of speech interact and how this may be computed in the human brain, using models and approaches from nonhuman primate studies. I explore the extent to which domain-general approaches may be able to account for some of these neural findings. Finally, I address the importance of extending these findings into a better understanding of the social use of speech in conversations.

Talker adaptation improves speech processing efficiency by reducing possible mappings between talkers' speech acoustics and listeners' phonemic representations. We investigated the functional neuroana...
Purpose Talkers typically use a slow speaking rate when producing clear speech, a speaking style that has been widely shown to improve intelligibility over conversational speech in difficult communica...
Purpose This study sought to identify the articulator-specific mechanisms that underlie reduced and enhanced acoustic vowel contrast in talkers with dysarthria due to Parkinson's disease (PD). Method ...
The ability to selectively attend to speech in the presence of other competing talkers is critical for everyday communication; yet the neural mechanisms facilitating this process are poorly understood...
The aim of the study was to compare transcription-based speech intelligibility and scaled speech severity for the detection of mild speech impairments, by studying these metrics across talkers with...
The primary goal of the present study is to test whether neural activity in brain regions associated with processing threat and social stimuli may underlie paranoid thinking.
This study will use a neuroeconomic paradigm with state-of-the-art imaging protocols to probe abnormal social reward processing underlying social withdrawal in symptomatic trauma-exposed w...
National data indicate over 650,000 children and adolescents are exposed to physical, sexual, or emotional abuse or physical or emotional neglect each year. Moreover, youth with a history ...
In this study, investigators will examine how temporal rate processing might be affected when the width of neural excitation narrows. The manipulation of neural excitation width will be ac...
An EEG study using continuous speech stimuli to assess neural language processing in a hearing impaired population. Participants listen to short radio excerpts in different Signal to Noise...
A technique that induces the processing of disturbing memories and experiences, by stimulating neural mechanisms that are similar to those activated during REM sleep. The technique consists of eye movements following side-to-side movements of the index and middle fingers, or the alternate tapping of the hands on the knees. This procedure triggers the processing of information, thus facilitating the connection of neural networks.
A computer architecture, implementable in either hardware or software, modeled after biological neural networks. Like the biological system in which the processing capability is a result of the interconnection strengths between arrays of nonlinear processing nodes, computerized neural networks, often called perceptrons or multilayer connectionist models, consist of neuron-like units. A homogeneous group of units makes up a layer. These networks are good at pattern recognition. They are adaptive, performing tasks by example, and thus are better for decision-making than are linear learning machines or cluster analysis. They do not require explicit programming.
Treatment for individuals with speech defects and disorders that involves counseling and use of various exercises and aids to help the development of new speech habits.
Professionals who work with persons affected by social disadvantages such as POVERTY; mental and physical illness or disability, and social injustice. Their focus is on both the individual and his or her environment, including violations of their civil liberties and human rights.
A personality disorder in which there are oddities of thought (magical thinking, paranoid ideation, suspiciousness), perception (illusions, depersonalization), speech (digressive, vague, overelaborate), and behavior (inappropriate affect in social interactions, frequently social isolation) that are not severe enough to characterize schizophrenia.
