Inner speaking, the covert talking that goes on inside a person's mind, can shape creative thought. How phenomenological properties and quality of inner speaking correlate with potential, however, is an open scientific problem. To explore this, participants ( n = 267) filled in revised Varieties Speech Questionnaire Launay Slade Hallucination Scale (auditory subscale), performed three tests pot...

The phenomenon of auditory verbal hallucinations (AVHs) is one of the most intriguing features of the psychiatric literature. Two alternative models of the development of AVHs in both normal and psychotic populations are proposed. In the disruption to internalisation (DI) model, AVHs result from a disruption to the normal processes of internalisation of inner speech. In the re-expansion (RE) mo...

This paper confirms and exploits the observation that early overt self-interruptions and repairs of phonological speech errors very likely are reactions to inner speech, not to overt speech. In an experiment eliciting word–word and nonword–nonword phonological spoonerisms it is found that self-interruptions and repairs come in two classes, one class of reactions to inner speech, another with re...

OBJECTIVE This study investigated the functional neuroanatomy of inner speech and auditory verbal imagery in schizophrenic patients predisposed to auditory hallucinations. METHOD Eight patients with schizophrenia with a history of prominent auditory hallucinations and six comparison subjects underwent functional magnetic resonance imaging while generating inner speech or imagining external sp...

Talking silently to ourselves occupies much of our mental lives, yet the mechanisms underlying this experience remain unclear. The following experiments provide behavioral evidence that the auditory content of inner speech is provided by corollary discharge. Corollary discharge is the motor system's prediction of the sensory consequences of its actions. This prediction can bias perception of ot...

BACKGROUND The neurocognitive basis of auditory hallucinations is unclear, but there is increasing evidence implicating abnormalities in processing inner speech. Previous studies have shown that people with schizophrenia who were prone to auditory hallucinations demonstrated attenuated activation of brain areas during the monitoring of inner speech. AIMS To investigate whether the same patter...

The problem of visual speech representation for bimodal based speech recognition includes particular challenges in the modeling of the inner lip texture reflecting different pronunciations, such as the appearance of teeth and tongue. This paper proposes and analyzes several possible statistical inner lip texture descriptors to determine an effective and discriminant feature. Simply using graysc...

A theory of speech monitoring, proposed by Levelt (1983), assumes that the quality of one's speech is checked by the speech comprehension system. This system inspects one's own overt speech but would also inspect an inner speech plan ("the inner loop"). We have elaborated and tested this theory by way of formalizing it as a computational model. This model includes a new proposal concerning the ...
