New research demonstrates that speech dysfunction detected via smartphone voice calls can be used to identify people with isolated rapid eye movement sleep behaviour disorder (iRBD). Using a smartphone app to collect voice recordings, a sample duration of 8 min was sufficient to differentiate between people with iRBD and healthy volunteers; a significant difference between the groups was found in monopitch and imprecise vowel articulation. iRBD is recognized as a prodromal stage of Parkinson disease, so the test could provide an accessible, early disease biomarker.

智能手机通话检测早期帕金森病

新的研究表明，通过智能手机语音通话检测到的言语功能障碍可用于识别患有孤立性快速眼动睡眠行为障碍 （iRBD） 的人。使用智能手机应用程序收集录音，样本持续时间为 8 分钟足以区分 iRBD 患者和健康志愿者;在单音调和不精确的元音发音方面发现各组之间的显着差异。iRBD 被认为是帕金森病的前驱期，因此该测试可以提供可访问的早期疾病生物标志物。
