This paper explores some of the similarities and differences between hysteria and hypochondriasis and suggests that voice disorders are a prototype of disorders which reflect the intricate interplay of emotional, cognitive and physiological functions. Speech production requires the involvement of various systems of the body, including the central nervous system, respiratory and vocal systems. Voice disorders can take many different forms and can be caused by a variety of factors. A review of the relevant literature is presented along with a clinical case record of a woman with hysterical dysarthria.

Phonatory dysfunction is a frequent component of dysarthria and often is a primary feature noted in clinical assessment. But the vocal impairment can be difficult to assess because (a). the analysis of voice disorder of any kind can be challenging, and (b). the voice disorder in dysarthria often occurs along with other impairments affecting articulation, resonance, and respiration. A promising assessment tool is multi-parameter acoustic analysis, such as the Multi-Dimensional Voice Program (MDVP). Part 1 of this paper recommends procedures and standards for the acoustic analysis of voice, including (1). selection of the sample to be analyzed, (2). signal quality requirements, (3). availability of normative data for both genders and different ages of speakers, (4). reliability of analysis, and (5). correlation of acoustic results with results from other methods of analysis. In Part 2, acoustic data are reviewed for the dysarthria associated with Parkinson disease (PD), cerebellar disease, amyotrophic lateral sclerosis (ALS), traumatic brain injury (TBI), unilateral hemispheric stroke, and essential tremor. Tentative profiles of voice disorder are described for these conditions. These profiles may serve as hypotheses for future research. Although several issues remain to be resolved in the acoustic analysis of voice disorder in dysarthria, steps can be taken now to promote the reliability, validity, and clinical utility of such analyses. (1). As a result of this activity, the participant will be able to describe ways in which an optimal multi-dimensional analysis of voice can be performed with modern acoustic analysis systems. (2). As a result of this activity, the participant will be able to apply multi-dimensional acoustic analysis of voice to individuals who have a dysarthria-related voice disorder. (3). As a result of this activity, the participant will be able to identify major sources of normative data on the Multi-Dimensional Voice Program.

The aim of the study was firstly to document the acoustic parameters of voice using the Multidimensional Voice Program (MDVP, Kay Elemetrics) in a group of children with dysarthria subsequent to treatment for cerebellar tumour (CT). Then, secondly, compare the acoustic findings to perceptual voice characteristics as described by the GIRBAS (grade, instability, roughness, breathiness, asthenicity, strain). The assessments were performed on 29 voice samples; 9 cerebellar tumour participants with dysarthria, and 20 control participants. None of the control voices were rated as exhibiting any of the six parameters described by the GIRBAS, while 7 of the CT participants were noted to have at least a mild voice disorder. Roughness, instability, breathiness and asthenicity were all identified as voice characteristics in the CT voice samples. Acoustically, the CT voice samples differed significantly from the controls' voices on frequency and amplitude perturbation measures. Our findings confirmed voice dysfunction as a component of dysarthria in children treated for cerebellar tumour, and discussed the links between acoustic and perceptual descriptions.

Children with classic galactosemia are at risk for motor speech disorders resulting from disruptions in motor planning and programming (childhood apraxia of speech or CAS) or motor execution (dysarthria). In the present study of 33 children with classic galactosemia, 21% were diagnosed with CAS, 3% with ataxic dysarthria, and 3% with mixed CAS-dysarthria. Voice disorders due to laryngeal insufficiency were common in children with dysarthria and co-occurred with CAS. Most (58%) of the children with classic galactosemia had decreased respiratory-phonatory support for speech, and 33% had disturbed vocal quality that was indicative of cerebellar dysfunction. Three children, two diagnosed with CAS and one not diagnosed with a motor speech disorder, had vocal tremors. Treatment of voice dysfunction in neurogenic speech disorders is discussed.
