“…Speech volume: IQR of MFCC0, a measure related to the variation of speech volume, correlates positively with BPRS total score. In line with our result, it has been observed that patients diagnosed with schizophrenia deviate more from the norm for speech volume and other descriptors [2]. Individual positive items show no correlation with a variation in speech volume.…”

“…However, IQR of articulation rate correlates negatively with the BPRS total score and many positive items. For children with schizophrenia, it was observed that they have a more excessive variation in speech rate [2]. We found the opposite to be the case for our dataset.…”

“…Compared to this withinpatient study, our paper investigates more acoustic descriptors, including a more robust estimator of voice tenseness, between patients. An exhibition of inadequate speech behaviors, e.g., in volume, in rate, and in pitch variation, was found in children diagnosed with schizophrenia compared to a control group of the same size and demographic [2]. The same study observed that children with schizophrenia were not identifiable by a single speech behavior, but that they often deviated more from the norm on many speech-related behaviors, e.g., speaking too loudly or too quietly.…”

“…For schizophrenia alone, 23.6 million cases were reported globally in 2013 [1]. Psychotic disorders affect how we speak [2] and how we express ourselves with facial expressions [3,4]. Thus, medical assessments have included speech-related descriptors for a long time [5,6].…”

Various forms of psychotic disorders, including schizophrenia, can influence how we speak. Therefore, clinicians assess speech and language behaviors of their patients. While it is difficult for humans to quantify speech behaviors precisely, acoustic descriptors, such as tenseness of voice and speech rate, can be quantified automatically. In this work, we identify previously unstudied acoustic descriptors related to the severity of psychotic symptoms within a clinical population (N=29). Our dataset consists of semi-structured interviews between patients and clinicians. Psychotic disorders are often characterized by two groups of symptoms: negative and positive. While negative symptoms are also prevalent in disorders such as depression, positive symptoms in psychotic disorders have rarely been studied from an acoustic and computational perspective. Our experiments show relationships between psychotic symptoms and acoustic descriptors related to voice quality consistency, variation of speech rate and volume, vowel space, and a parameter of glottal flow. Further, we show that certain acoustic descriptors can track a patient's state from admission to discharge. Finally, we demonstrate that measures from the Brief Psychiatric Rating Scale (BPRS) can be estimated with acoustic descriptors.

“…Only two studies have employed systematic ratings of suprasegmental linguistic features. Simmons and Baltaxe (1975) and Goldfarb, Goldfarb, Braunstein, and Scholl (1972) used a classification system for language faults for groups of relatively high-functioning autistic adolescents and children. Simmons and Baltaxe found that the spontaneous language samples of these subjects suggested two subgroups, those that showed no language faults and those with numerous faults.…”

Reward value of prosodic features of language for autistic, mentally retarded, and normal children

The present study pursued hypotheses relevant to prosodic abnormalities in the expressive language of autistic children. An operant paradigm was employed to measure the intrinsic reinforcing value of a verbally presented story for autistic, mentally retarded, and normal groups controlling for chronological age and performance mental age. Results suggested that both autistic and mentally retarded children could perceive prosodic cues, although only mentally retarded children are able to use them in their expressive language. It was also suggested that linguistic stimuli may have less intrinsic reinforcement value for autistic and mentally retarded children than for normal children. Implications for future research and treatment were discussed.
