This work estimates the uncertainty contributions of speech level parameters measured with a contact-sensor-based device and a headworn microphone. Four contributions are considered: (1) instrumental uncertainty, related to device calibration; (2) method repeatability and (3) reproducibility, estimated through repeated measurements without and with device repositioning, respectively; (4) source reproducibility, due to the variability of human speech. To ascertain changes in speech production, differences between measures should be at least higher than the expanded uncertainty. In the case of device repositioning, the expanded uncertainty combines contributions (1), (3), and (4). When the device is not repositioned, it combines contributions (2) and (4).
这项工作估计了使用基于接触传感器的设备和头戴式麦克风测量的语音水平参数的不确定度贡献。考虑了四个贡献：（1）仪器不确定度，与设备校准有关；（2）方法重复性和（3）再现性，分别通过无设备重新定位和有设备重新定位的重复测量来估计；（4）源再现性，由于人类语音的可变性。为了确定语音产生的变化，测量值之间的差异至少应高于扩展不确定度。在设备重新定位的情况下，扩展不确定度结合了贡献（1）、（3）和（4）。当不重新定位设备时，它结合了贡献（2）和（4）。
