The vocal quality of a patient is modeled by means of a Dysphonia Severity Index (DSI), which is designed to establish an objective and quantitative correlate of the perceived vocal quality. The DSI is based on the weighted combination of the following selected set of voice measurements: highest frequency (F 0 -High in Hz), lowest intensity (I-Low in dB), maximum phonation time (MPT in s), and jitter (%). The DSI is derived from a multivariate analysis of 387 subjects with the goal of describing, purely based on objective measures, the perceived voice quality. It is constructed as DSI=0.13 x MPT + 0.0053 x F 0 -High – 0.26 x I-Low – 1.18 x Jitter (%) + 12.4. The DSI for perceptually normal voices equals +5 and for severely dysphonic voices –5. The more negative the patient's index, the worse is his or her vocal quality. As such, the DSI is especially useful to evaluate therapeutic evolution of dysphonic patients. Additionally, there is a high correlation between the DSI and the Voice Handicap Index score.

AbstractObjective:To investigate perceptual, acoustic and aerodynamic voice parameters in obese individuals.Methods:Twenty obese and 20 normal-weight volunteers underwent voice evaluation by laryngoscopy, acoustic analysis, aerodynamic measurement and perceptual analysis (using the grade-roughness-breathiness-asthenia-strain (‘GRBAS') scale and the Voice Handicap Index 10 scale). Data from both subject groups were compared.Results:No difference was found in acoustic analysis parameters between the two groups (p > 0.05). Maximum phonation time in the obese group (mean ± standard deviation, 19.6 ± 4.9 seconds) was significantly shorter than in controls (26.4 ± 4.1 seconds) (p < 0.001), although the s/z ratio was very similar between the two groups. In the obese and control groups, the mean ± standard deviation grade-roughness-breathiness-asthenia-strain scores were 1 ± 1.3 and 0.2 ± 0.6 (p = 0.002) and the mean ± standard deviation Voice Handicap Index 10 scores were 0.5 ± 1.2 and 1.2 ± 1.7 (p = 0.27), respectively.Conclusion:Obese individuals had poorer vocal quality as judged by the grade-roughness-breathiness-asthenia-strain scale, and reduced maximum phonation time. However, there was no change in voice quality as assessed by acoustic analysis and Vocal Handicap Index 10 score, compared with controls.

Objectives 1) To present the objective and subjective analysis of voice quality following treatment of an early epidermoid glottic carcinoma. 2) Results from the objective evaluation of the voice, along with the self-evaluation of voice quality quantified using the Voice Handicap Index of a group of patients treated with endoscopic laser surgery, are compared with patients treated with radiotherapy. Methods We performed an objective voice evaluation, as well as a physical, emotional, and functional well-being assessment of 19 patients treated with laser surgery and 18 patients treated with radiotherapy. The data obtained was gathered in the statistical database SPSS 12.0. The statistical analysis used was the “Student t test” in order to compare averages and the Chi-squared test for comparing proportions. The statistical differences were considered significant when p was lower than 0.05. Results Voice quality is affected both by surgery and radiotherapy. Voice parameters only show differences in the maximum phonation time between both treatments (p < 0,005). Patients Self-Perception Analysis (Voice Handicap Index) Upon completing the comparison between the two groups, the statistical difference is significant, in favor of the radiotherapy patients in functional and emotional ratings, as well as the global scores (p < 0,005). No significant differences were found in the physical scales. Conclusions There is a reduced impact in patient's perception of voice quality after radiotherapy, despite no significant differences in vocal quality between radiotherapy and laser cordectomy.

Aim of study: Evaluation of the speech therapy on voice quality in patients with unilateral vocal fold palsy. Material and methods: The study group included 11 patients, 8 women and 3 men, in age between 16 to 72 years, with unilateral vocal fold palsy, diagnosed in ENT Department of Warsaw Medical University between 2017-2018. Each person completed questionnaires: the voice disability self-assessment scale (VHI), the voice-based quality of life (VRQoL) scale, the vocal tract discomfort scale (VTD). All questionnaires were completed twice, before and after the voice therapy. In addition, the acoustic analysis of the voice, the assessment of the maximum phonation time and the breathing tract were performed twice in each patient. Each of the patients had a voice rehabilitation consisting of a series of 10 meetings. Results: Statistical analysis of the results of maximum phonation time, the self-assessment of voice disability, the quality of life depending on the voice, discomfort of the vocal tract voice acoustic analysis showed statistically significant differences in the results before and after rehabilitation (p <0.005). In addition, the improvement of the respiratory tract was observed in the majority of patients. Conclusions: Speech therapy significantly affects the voice quality of patients with unilateral laryngeal nerve palsy.

Background: Previous studies have documented the effectiveness of voice therapy in terms of voice quality outcomes rather than quality of life outcomes. Objective: To compare the quality of life among patients with voice disorders, before and after voice therapy. Methods: Thirty-six patients with voice disorders who visited the Speech Clinic at Ramathibodi Hospital from March 2013 to January 2015 were enrolled. Thirty minutes per session within 10 weeks period of voice therapy program were used. The voice therapy approaches included direct and indirect therapy. The outcomes of this study were measured using Dr. Speech software version 5 for acoustic analysis and the Voice Handicap Index in Thai version for quality of life. Data was analyzed by descriptive and inferential statistics (Paired t test). Results: The total participants were 36 patients with a mean age of 51.31 years. They were divided to 4 groups according to the causes of voice disorders that were 18 patients for structural cause, 8 patients for functional cause, 6 patients for neurological cause, and 4 patients for inflammatory cause. The results for both voice quality and quality of life after voice therapy improved and showed statistically significant differences (P < .05). The patients with all causes of voice disorders were statistically significant differences in total the Voice Handicap Index scores (P < .05). Moreover the structural causes group exhibited statistically significant differences in all subscales (P < .05) but the others causes groups were not statistically significant differences in emotional subscale for functional causes, physical subscale for neurological causes, and functional subscale for inflammatory cause (P > .05) Conclusions: Voice therapy might be an effective treatment to decrease the severity of voice disorders in role of voice quality and quality of life, especially voice disorders from structural causes.

PURPOSE: To compare the vocal self-perception and vocal complaints reported by two groups of students of the pedagogy course (freshmen and graduates); to relate the vocal self-perception to the vocal complaints for these groups; and to compare the voice quality of the students from these groups through perceptual auditory assessment and acoustic analysis. METHODS: Initially, 89 students from the pedagogy course answered a questionnaire about self-perceived voice quality and vocal complaints. In a second phase, auditory-perceptual evaluation and acoustic analyses of 48 participants were made through voice recordings of sustained vowel emission and poem reading. RESULTS: The most reported vocal complaints were fatigue while using the voice, sore throat, effort to speak, irritation or burning in the throat, hoarseness, tightness in the neck, and variations of voice throughout the day. There was a higher occurrence of complaints from graduates than from freshmen, with significant differences for four of the nine complaints. It was also possible to observe the relationship between vocal self-perception and complaints reported by these students. No significant differences were observed in the results of auditory-perceptual evaluation; however, some graduates had their voices evaluated with higher severity of deviation of normalcy. During acoustic analysis no difference was observed between groups. CONCLUSION: The increase in vocal demand by the graduates may have caused the greatest number and diversity of vocal complaints, and several of them are related to the self-assessment of voice quality. The auditory-perceptual evaluation and acoustic analysis showed no deviations in their voice.

Purpose Dysphonia can be evaluated by both patient-reported quality of life instruments and objective acoustic and aerodynamic analyses. However, less is known about the association between the two metrics. The goal of this study was to perform a meta-analysis of the correlation of the Voice Handicap Index (VHI-30) with the following objective parameters: fundamental frequency, jitter, shimmer, harmonics to noise ratio, noise to harmonic ratio, maximum phonation time, and the Dysphonia Severity Index. Method A literature search was performed in the PubMed, Scopus, and Cumulative Index of Nursing and Allied Health Literature databases. Inclusion criteria were subjects age 18 years and older with voice complaints and assessed by both VHI-30 and objective voice analysis. Results A literature search resulted in 1,297 unique articles, of which 310 underwent full-text review and 17 studies were included in quantitative analysis. Significant pooled correlation was observed for VHI-30 total with jitter (.301 [.177; .416]), shimmer (.255 [.162; .344]), noise to harmonic ratio (.200 [.111; .285]), maximum phonation time (−.227 [−.352; −.094]), and Dysphonia Severity Index (−.254[−.455; −.0286]). Significant correlations were observed in 4/7 objective parameters with the Physical subscale, 3/7 with the Functional subscale, and 2/7 with the Emotional subscale. All significant correlations were negligible (0–.3) or low (.3–.5). Conclusions Results from meta-analysis showed that correlations between objective voice parameters and the VHI-30 were negligible or low. Further study is needed to determine if correlations vary by patient demographics or specific pathology.

PurposeAlthough there is a long history of use of semi-occluded vocal tract gestures in voice therapy, including phonation through thin tubes or straws, the efficacy of phonation through tubes has not been established. This study compares results from a therapy program on the basis of phonation through a flow-resistant tube (FRT) with Vocal Function Exercises (VFE), an established set of exercises that utilize oral semi-occlusions.MethodTwenty subjects (16 women, 4 men) with dysphonia and/or vocal fatigue were randomly assigned to 1 of 4 treatment conditions: (a) immediate FRT therapy, (b) immediate VFE therapy, (c) delayed FRT therapy, or (d) delayed VFE therapy. Subjects receiving delayed therapy served as a no-treatment control group.ResultsVoice Handicap Index (Jacobson et al., 1997) scores showed significant improvement for both treatment groups relative to the no-treatment group. Comparison of the effect sizes suggests FRT therapy is noninferior to VFE in terms of reduction in Voice Handicap Index scores. Significant reductions in Roughness on the Consensus Auditory-Perceptual Evaluation of Voice (Kempster, Gerratt, Verdolini Abbott, Barkmeier-Kraemer, & Hillman, 2009) were found for the FRT subjects, with no other significant voice quality findings.ConclusionsVFE and FRT therapy may improve voice quality of life in some individuals with dysphonia. FRT therapy was noninferior to VFE in improving voice quality of life in this study.

AbstractObjectives:A wide range of well validated instruments is now available to assess voice quality and voice-related quality of life, but comparative studies of the responsiveness to change of these measures are lacking. The aim of this study was to assess the responsiveness to change of a range of different measures, following voice therapy and surgery.Design:Longitudinal, cohort comparison study.Setting:Two UK voice clinics.Participants:One hundred and forty-four patients referred for treatment of benign voice disorders, 90 undergoing voice therapy and 54 undergoing laryngeal microsurgery.Main outcome measures:Three measures of self-reported voice quality (the vocal performance questionnaire, the voice handicap index and the voice symptom scale), plus the short form 36 (SF 36) general health status measure and the hospital anxiety and depression score. Perceptual, observer-rated analysis of voice quality was performed using the grade–roughness–breathiness–asthenia–strain scale. We compared the effect sizes (i.e. responsiveness to change) of the principal subscales of all measures before and after voice therapy or phonosurgery.Results:All three self-reported voice measures had large effect sizes following either voice therapy or surgery. Outcomes were similar in both treatment groups. The effect sizes for the observer-rated grade–roughness–breathiness–asthenia–strain scale scores were smaller, although still moderate. The roughness subscale in particular showed little change after therapy or surgery. Only small effects were observed in general health and mood measures.Conclusion:The results suggest that the use of a voice-specific questionnaire is essential for assessing the effectiveness of voice interventions. All three self-reported measures tested were capable of detecting change, and scores were highly correlated. On the basis of this evaluation of different measures' sensitivities to change, there is no strong evidence to favour either the vocal performance questionnaire, the voice handicap index or the voice symptom scale.
