“…Hence, depending on the severity of psychosis, we believe that sentences should be encouraged when assessing auditory function in schizophrenia patients. This is consistent with a study done by Lee et al 45 that found schizophrenia patients without auditory hallucination demonstrate relatively similar ability with healthy controls when listening to narrative text in low noise conditions. In addition, schizophrenia patients have more impairment in comprehending non-literal compared to literal sentences.…”

“…An investigation of speech perception ability using narrative texts embedded in phonetic noise has also been documented. 16 In addition, a study by Ross et al 17 also suggested that schizophrenia patients demonstrated no deficits in recognizing monosyllabic words in background noise. Another study using Speech-in-Babble Perception test, 18 however, revealed that patients with first-episode psychosis do have difficulties when listening to targeted signals embedded in noise.…”

ObjectiveThe present, case-control, study investigates binaural hearing performance in schizophrenia patients towards sentences presented in quiet and noise.MethodsParticipants were twenty-one healthy controls and sixteen schizophrenia patients with normal peripheral auditory functions. The binaural hearing was examined in four listening conditions by using the Malay version of hearing in noise test. The syntactically and semantically correct sentences were presented via headphones to the randomly selected subjects. In each condition, the adaptively obtained reception thresholds for speech (RTS) were used to determine RTS noise composite and spatial release from masking.ResultsSchizophrenia patients demonstrated significantly higher mean RTS value relative to healthy controls (p=0.018). The large effect size found in three listening conditions, i.e., in quiet (d=1.07), noise right (d=0.88) and noise composite (d=0.90) indicates statistically significant difference between the groups. However, noise front and noise left conditions show medium (d=0.61) and small (d=0.50) effect size respectively. No statistical difference between groups was noted in regards to spatial release from masking on right (p=0.305) and left (p=0.970) ear.ConclusionThe present findings suggest an abnormal unilateral auditory processing in central auditory pathway in schizophrenia patients. Future studies to explore the role of binaural and spatial auditory processing were recommended.

“…Schizophrenia patients with hallucinations were not impaired on the nonlinguistic, auditory, continuous-performance task-suggesting that these deficits were specific to verbal working memory. Using a similar paradigm, Lee and colleagues 50 replicated the finding of impairment on a masked-speech tracking test. This impairment was still observed eight weeks later, well after the hallucinations subsided-suggesting that a speech-perception dysfunction may be a trait characteristic.…”

Auditory verbal hallucinations are a common and distressing symptom experienced by patients with schizophrenia. They can be understood as arising from an impairment in reality monitoring-the process by which internally and externally generated events are distinguished. This impairment might arise through primary abnormalities in the reality-monitoring mechanism or through secondary mechanisms (abnormalities in the perceptual characteristics of internally generated events or in the perception of externally generated events). This article examines evidence for and against an association between abnormalities in reality monitoring and auditory verbal hallucinations in schizophrenia. A comprehensive review of the psychological literature suggests that there is little evidence for an association between auditory verbal hallucinations and secondary mechanisms leading to abnormalities in reality monitoring. There is some evidence suggesting that hallucinators show a primary reality-monitoring abnormality that is most apparent when patients are required to distinguish self from other in real time. To draw firmer conclusions, however, it is imperative that future studies select patient populations precisely, match control groups, and use consistent criteria for defining hallucinators.

“…Studies have also looked at language production, speech production, and perception, rather than specifically at inner speech itself in patients who experience AVHs. The left superior temporal cortex, which supports linguistic functions, has consistently been reported to activate during auditory–verbal hallucinations in schizophrenia patients . Auditory verbal hallucinations have been shown to be related to defined cortical areas linked to specific language functions.…”

There has been a large growth in research on AVHs in recent decades dominated by neurobiological and neuroimaging studies. Future research should include focus on phenomenological aspects and AVHs change over the course of developing illness. Integration between branches of enquiry is needed, and the risk is that without this, models are proposed and investigated that bear scant relevance to the symptom itself.
