Correlation of the Dysphonia Severity Index (DSI), Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V), and Gender in Brazilians With and Without Voice Disorders

Comparison of Dysphonia Severity Index and its Parameters Among Individuals with Multiple Sclerosis and Healthy Subjects

“…The DSI using a standardized formula examines changes in acoustic parameters of vocal quality (maximum phonation time, jitter, minimum intensity, and maximum fundamental frequency); therefore, the significant difference of these parameters among the two groups in the present study resulted in a significant difference in the scores of the index between these groups. Previous studies have shown that this index has the ability to differentiate healthy people from people with voice problems (12,15,17,27). Based on the results of the present study, which is in line with previous studies (4,6), individuals with multiple sclerosis, including those at high risk of phonation impairments, and the DSI as a sensitive tool to these impairments in this group, can be used in daily clinical evaluations for diagnostic purposes of patients with multiple sclerosis.…”

“…Based on studies conducted using this index, the DSI, as well as other vocal acoustic assessments are able to determine the severity of voice disorders, changes made before and after the treatment of vocal damage, and differentiate between individuals with and without voice problems (12,14,16). Another advantage of this index is the strong correlation with perceptual valid tools, such as VHI, GRBAS, CAPE-V, and instrumental evaluations, such as Video Laryngostroboscopy (12,16,17). Wuyts et al also believed that the DSI is not influenced by gender, since the maximum phonation time in males is compensated by the highest frequency in the female population and the average score of the DSI in females and males are relatively similar (11,18).…”

Diagnostic Accuracy of Dysphonia Classification of DSI and AVQI

“…DSI is a multivariate index, which includes four parameters that are weighted and then tallied to quantify voice quality . DSI was evaluated as a useful and feasible measurement, with acceptable interexaminer variability . This index has been used clinically as a measurement to evaluate the effects of voice therapy, vocal training, and phonosurgery .…”

“…This index has been used clinically as a measurement to evaluate the effects of voice therapy, vocal training, and phonosurgery . Further investigations of DSI showed geographical and ethnic variations, interdevice reliability differences, test–retest variability between 1.74 to 2.04 and 2.49, influencing factors of age but not in gender, and the impact of psychological state of subjects during measurement …”
