ABSTRACT Introduction: Auditory verbal hallucinations (AVH) are a core symptom of psychotic disorders such as schizophrenia but are also reported in 10–15% of the general population. Impairments in self-voice recognition are frequently reported in schizophrenia and associated with the severity of AVH, particularly when the self-voice has a negative quality. However, whether self-voice processing is also affected in nonclinical voice hearers remains to be specified. Methods: Thirty-five…

The perceived salience of vocal emotions is dampened in non-clinical auditory verbal hallucinations
TLDR
The findings suggest that emotional salience in vocalisations is dampened as a function of increased AVH proneness, which could be related to changes in the acoustic representations of emotions or reflect top-down expectations of less salient information in the social environment.
Changes in motor preparation affect the sensory consequences of voice production in voice hearers
Changes in Motor Preparation Affect the Sensory Consequences of Voice Production in Voice Hearers
Attention to voices is increased in non-clinical auditory verbal hallucinations irrespective of salience
Investigations of Verbal Cues and Self-Voice Perception Model
It is of great significance to explore the influence mechanism of verbal cues on self-voice perception under different conditions. The aim of this study is to probe the effects of verbal and…

Expectancy changes the self-monitoring of voice identity
TLDR
Voice-morphing (self-other) is utilized to manipulate (un-)certainty in self-voice attribution in a button-press paradigm to investigate how levels of self- Voice certainty alter brain activation in regions monitoring voice identity areas and unexpected changes in voice playback quality.
Expectancy changes the self‐monitoring of voice identity
TLDR
Voice‐morphing (self‐other) is utilized to manipulate (un‐)certainty in self‐voice attribution in a button‐press paradigm to investigate how levels of self-voice certainty alter brain activation in brain regions monitoring voice identity and unexpected changes in voice playback quality.

The Etiology of Auditory Hallucinations in Schizophrenia: From Multidimensional Levels
TLDR
Main findings include gene polymorphisms, glutamate level change, electroencephalographic alterations, and abnormalities of white matter fasciculi, cortical structure, and cerebral activities, especially in multiple regions, including auditory and language networks.

Is this my voice or yours? The role of emotion and acoustic quality in self-other voice discrimination in schizophrenia
TLDR
It is suggested that abnormalities in higher order processes (evaluation of the salience of a speech stimulus) modulate impaired self-other voice discrimination in schizophrenia and abnormal processing of negative self-generated speech may play a role in the experience of AVH.
Emotional self-other voice processing in schizophrenia and its relationship with hallucinations: ERP evidence.
TLDR
The association between LPP amplitude and hallucination severity suggests that auditory hallucinations are associated with enhanced sustained attention to negative cues conveyed by a nonself voice.
Voice-selective prediction alterations in nonclinical voice hearers
TLDR
Electroencephalography findings confirm that both prediction and comparison of predicted and perceived feedback to a self-generated voice are altered in individuals with AVH predisposition, which may establish a core feature of the psychosis continuum.
Misattribution of external speech in patients with hallucinations and delusions
Verbal self-monitoring and auditory verbal hallucinations in patients with schizophrenia
TLDR
The results suggest an association between delusions and impaired judgements about ambiguous sensory stimuli and the specific tendency of hallucinators to misattribute their distorted voice to someone else may reflect impaired awareness of internally generated verbal material.
Voice identity discrimination and hallucination-proneness in healthy young adults: a further challenge to the continuum model of psychosis?
TLDR
Findings suggest voice identity perception is not impaired in healthy individuals predisposed to hallucinations, adding a further challenge to the continuum model of psychotic symptoms.
Voices to reckon with: perceptions of voice identity in clinical and non-clinical voice hearers
TLDR
The findings overall point to significant difficulties recognizing familiar speakers and discriminating between unfamiliar speakers in people with schizophrenia, both with and without AVH, as well as multidimensional scaling of voice dissimilarity judgments.

Do Thoughts Have Sound? Differences between Thoughts and Auditory Hallucinations in Schizophrenia
TLDR
Findings are consistent with the cognitive hypothesis of auditory verbal hallucinations that confusion identifying the source of auditory hallucinations could be due, in part, to “hearing” one’s thoughts at the same volume as auditory hallucinations and spoken words.
