Reliability of OperaVOX against Multidimensional Voice Program (MDVP).

摘要: Objective To evaluate the agreement between OperaVOX and MDVP. Design Cross sectional reliability study. Setting University teaching hospital. Methods Fifty healthy volunteers 50 voice disorder patients had supervised recordings in a quiet room using by iPod's internal microphone with sampling rate of 45 kHz. A five-seconds recording vowel/a/was used to measure fundamental frequency (F0), jitter, shimmer noise-to-harmonic ratio (NHR). All 21 second recording. The recorded voices were also analysed MDVP. inter- intrasoftware was intraclass correlation (ICC) test Bland–Altman (BA) method. Mann–Whitney compare acoustic parameters patients. Results Nine severe aperiodic voice. ICC high confidence interval >0.75 for except NHR. For intersoftware BA analysis, excluding data sets, bias (95% LOA) F0, NHR 0.81 (11.32, −9.71); −0.13 (1.26, −1.52); −0.52 (1.68, −2.72); 0.08 (0.27, −0.10). reliability, it −1.48 (18.43, −21.39); 0.05 (1.31, −1.21); −0.01 (2.87, −2.89); 0.005 (0.20, −0.18), respectively. Normative from obtained. There significant difference all measured Opera-VOX (P < 0.001) F0 females (P = 0.87). Conclusion OperaVOX is comparable MDVP has consistency measuring jitter
