“…The influence of the software used in computer-assisted phoniatric examination cannot be disregarded, as is clear from the significant differences of simultaneously recorded measurement data from both programs processing identical signals. In spite of these differences, our findings endorse the literature results which prove high reliability and reproducibility of VRP measurements, and thus clinical usefulness [ 33 , 34 ].…”

Voice range profile (VRP) and evaluation using the dysphonia severity index (DSI) represent essentials of instrument-based objective voice diagnostics and are implemented in different standardized registration programs. The respective measurement results, however, show differences. The aim of the study was to prove these differences statistically and to develop a new parameter, the Vocal Extent Measure (VEM), which is not influenced by the measurement program. VRPs of 97 subjects were recorded by two examiners using the established registration programs DiVAS (XION medical) and LingWAVES (WEVOSYS) simultaneously. The VEM was developed on the basis of VRP area and perimeter. All 194 VRP files were analyzed for various parameters and gender independence. The registration programs exhibited significant differences in several vocal parameters. A significant gender influence for DSI was found with DiVAS (p < 0.01), but not with LingWAVES. The VEM quantified the dynamic performance and frequency range by a unidimensional, interval-scaled value without unit, mostly between 0 and 120. This novel parameter represents an intelligible and user-friendly positive measure of vocal function, allows simple and stable VRP description, and seems to be suitable for quantification of vocal capacity. In contrast to DSI, the VEM proved to be less susceptible to registration program and gender.

“…The dual‐microphone phonetogram system Voice Profiler 5.0 (Alphatron Medical Systems, Rotterdam, the Netherlands) was used for assessing the voice range profile 37 . The parameters of interest were the minimum and maximum fundamental frequencies ( f 0 ), measured in semitones (ST); the frequency range; the minimum and maximum voice intensity, defined as sound pressure level (SPL), measured in decibels (dB); and the intensity range.…”

Objective To investigate the impact of postoperative paresis on disease-specific quality of life (DSQoL) after thyroidectomy in patients with benign nodular thyroid disease. Study Design Observational study. Setting University hospital. Subjects and Methods Patients were evaluated before and 3 weeks and 6 months after surgery in an individual prospective cohort study using videolaryngostroboscopy (VLS), voice range profile, voice handicap index (VHI), multidimensional voice program, maximum phonation time (MPT), and auditory perceptual evaluation. Changes in DSQoL were assessed by the Thyroid-specific Patient-Reported Outcome measure. Cohen’s effect size was used to evaluate changes. Results Sixty-two patients were included, 55 of whom completed all examinations. Three weeks after surgery, a blinded VLS examination showed signs of paresis of either the recurrent laryngeal nerve or the external branch of the superior laryngeal nerve (RLN/EBSLN) in 13 patients (24%). A paresis corresponded to a 12 ± 28 point increase in VHI ( P = .002) and was associated with a significant 4.3 ± 7.5 semitone decrease in the maximum fundamental frequency ( P < .001) and a 5.3 ± 8.2 dB reduction in maximum intensity. Further, it was associated with a 4.5 ± 11.2 second reduction in MPT ( P = .001) and an increase of 0.40 ± 1.19 in grade, 0.42 ± 1.41 in roughness, and 0.36 ± 1.11 in breathiness. Signs of postoperative RLN/EBSLN paresis correlated with an 11.0-point ( P = .02) poorer improvement in goiter symptoms at both 3 weeks and 6 months after surgery. Conclusion Signs of RLN/EBSLN paresis after thyroidectomy were associated with less pronounced improvement in goiter symptoms in patients with thyroid nodular disease. However, thyroidectomy was associated with an overall improved DSQoL by 6 months after surgery.

“…Further, the intra-examiner variation of the assessment when using the multi-vowel approach is below the clinically relevant differences. 36 The sample sizes met the requirements of the a priori power calculation, and thereby reduced the risk of type II errors. Overall, the study has high external validity and results are applicable on other patient populations with LIN and/or NNL, before and after TLM-cordectomy.…”

“…Voice range profiles Complete voice range profiles (VRP) using the Voice Profiler Ò equipment replaced recordings of frequency ranges and softest intensities. The VRP assessment is clinically reliable 36 and recordings using this equipment can be conducted in standard quiet office surroundings. We measured frequency and intensity measures (minimum, maximum, and ranges) and VRP area as the dependent variables (Figure 1).…”
