Abstract：
UNASSIGNED: Patients lose their voice after laryngectomy for laryngeal cancer or aspiration prevention surgery for severe dysphagia. To assist such patients, we developed and verified the utility of a novel vocalization method using a device termed the voice retriever (VR), in which the sound source is placed in the mouth.
UNASSIGNED: We investigated the effectiveness of the VR in patients. The VR consists of a mouthpiece with a built-in speaker and a dedicated application that serves as the sound source. We compared the speech intelligibility and naturalness in normal participants using VR and an electrolarynx (EL) for the first time as well as the voice-related quality of life (V-RQOL) in patients with dysphonia before and after using the VR.
UNASSIGNED: The VR produced significantly higher 100-syllable test scores as well as fluency, amount of additional noise, intonation, intelligibility and overall long reading test ratings in the first-time VR and EL users. Furthermore, the VR use significantly improved the V-RQOL of participants with dysphonia.
UNASSIGNED: Compared to EL, VR allows more effective speech improvement in participants without experience using an alternative vocalization method and improves the V-RQOL in patients with dysphonia.
UNASSIGNED: Step 4.

摘要：
■喉癌切除术或严重吞咽困难的防误吸手术后患者失去声音。为了帮助这些病人，我们使用称为语音检索器（VR）的设备开发并验证了一种新颖的发声方法的实用性，其中声源放在嘴里。
■我们调查了VR在患者中的有效性。VR由带有内置扬声器的话筒和用作声源的专用应用程序组成。我们首次比较了使用VR和电喉部（EL）的正常参与者的语音清晰度和自然性，以及使用VR前后的发声障碍患者的语音相关生活质量（V-RQOL）。
■VR产生了显着更高的100音节考试成绩以及流畅性，额外的噪音，语调,首次使用VR和EL用户的清晰度和整体长阅读测试等级。此外，VR的使用显著改善了发声障碍参与者的V-RQOL.
■与EL相比，VR可以在没有使用替代发声方法经验的情况下对参与者进行更有效的语音改善，并改善了发声障碍患者的V-RQOL。
■步骤4.
