目的评价OperaVOX与MDVP的一致性。设计截面可靠性研究。大学教学医院。方法50名健康志愿者和50名语音障碍患者在安静的房间使用iPod内置麦克风进行OperaVOX录音，采样率为45kHz。用5秒的元音/ A /录音测量基频（F0）、抖动、闪烁和噪声谐波比（NHR）。所有健康志愿者和21名患者都进行了第二次录音。记录的声音也使用MDVP进行分析。采用类内相关（ICC）检验和Bland-Altman （BA）方法对软件间和软件内可靠性进行了分析。采用曼-惠特尼试验比较健康志愿者和患者的声学参数。结果50例患者中有9例存在严重的非周期性声音。除NHR外，软件间可靠性和软件内可靠性的ICC都很高，置信区间为>0.75。软件间BA分析，排除严重非周期性语音数据集，F0、抖动、闪烁和NHR的偏差（95% LOA）为0.81 (11.32,-9.71)；-0.13 (1.26, -1.52)；-0.52 (1.68, -2.72)；0.08（0.27, -0.10）。软件内信度为-1.48 (18.43,-21.39)；0.05 (1.31, -1.21)；-0.01 (2.87, -2.89)；和0.005（0.20,-0.18）。获得健康志愿者的规范数据。Opera-VOX （P . 0）测量的所有声学参数在志愿者和患者之间有显著差异
ObjectiveTo evaluate the agreement between OperaVOX and MDVP.DesignCross sectional reliability study.SettingUniversity teaching hospital.MethodsFifty healthy volunteers and 50 voice disorder patients had supervised recordings in a quiet room using OperaVOX by the iPod's internal microphone with sampling rate of 45kHz. A five-seconds recording of vowel/a/was used to measure fundamental frequency (F0), jitter, shimmer and noise-to-harmonic ratio (NHR). All healthy volunteers and 21 patients had a second recording. The recorded voices were also analysed using the MDVP. The inter- and intrasoftware reliability was analysed using intraclass correlation (ICC) test and Bland-Altman (BA) method. Mann-Whitney test was used to compare the acoustic parameters between healthy volunteers and patients.ResultsNine of 50 patients had severe aperiodic voice. The ICC was high with a confidence interval of >0.75 for the inter- and intrasoftware reliability except for the NHR. For the intersoftware BA analysis, excluding the severe aperiodic voice data sets, the bias (95% LOA) of F0, jitter, shimmer and NHR was 0.81 (11.32, -9.71); -0.13 (1.26, -1.52); -0.52 (1.68, -2.72); and 0.08 (0.27, -0.10). For the intrasoftware reliability, it was -1.48 (18.43, -21.39); 0.05 (1.31, -1.21); -0.01 (2.87, -2.89); and 0.005 (0.20, -0.18), respectively. Normative data from the healthy volunteers were obtained. There was a significant difference in all acoustic parameters between volunteers and patients measured by the Opera-VOX (P
