DESCRIPTION (provided by applicant): Voice ambulatory biofeedback has the potential to significantly improve voice therapy effectiveness by targeting the hardest aspect of rehabilitation - carryover outside the therapy session (also known as retention or learning). While there is initial evidence that ambulatory biofeedback can alter vocal behavior (using simple pitch and loudness thresholds) when the biofeedback is present (i.e., a biofeedback effect), there have been no well-designed studies demonstrating the persistence of a vocal behavior change once the biofeedback was turned off. Meaning ambulatory biofeedback has demonstrated the ability to only temporarily modify a subject's vocal behavior, not enact a longer term change or retention/learning. According to motor control and learning literature, two aspects of biofeedback delivery will improve vocal motor learning: (i) decreased frequency of cueing (e.g., providing feedback every 2nd time exceeding threshold instead of every time) and (ii) average summary feedback (e.g., providing the percent correct over a time period). Furthermore, average summary feedback has the potential to provide positive feedback if the subject receives a high percentage - which is also known to strengthen retention. In order to apply (i) and (ii) in an ambulatory manner, more advanced platforms for monitoring and biofeedback are needed than are currently available. We recently developed a smartphone-based voice ambulatory monitor (named the Voice Health Monitor -VHM) for use in another NIH-funded study that also has biofeedback capabilities. The VHM will be used in the proposed project to provide three different structures of ambulatory biofeedback in order to decrease a subject's vocal loudness throughout the day. A control group (group 1) will be provided ambulatory biofeedback every time they voice louder than a biofeedback threshold, a second group (group 2) will be provided ambulatory biofeedback every fourth time they voice louder than a biofeedback threshold, and a third group (group 3) will be provided summary average statistics regarding their compliance below a biofeedback threshold every 20 minutes. It is hypothesized that decreased frequency (group 2) and summary average feedback (group 3) will result in better retention of the desired softer phonation when biofeedback is turned off compared to the control group.

描述（由申请人提供）：语音卧床生物反馈有可能通过针对康复的最难方面来显着提高语音疗法的效率 - 在治疗课程之外（也称为保留或学习）。虽然有最初的证据表明，当存在生物反馈（即生物反馈效应）时，卧床生物反馈可以改变声音行为（使用简单的音高和响度阈值），但没有明确的研究表明，一旦生物反馈被关闭，声音行为改变了。意味着卧床生物反馈证明了仅临时修改受试者的声音行为，而不是进行长期变化或保留/学习的能力。根据运动控制和学习文献，生物反馈交付的两个方面将改善声音运动学习：（i）提示的频率降低（例如，每隔第二次超过阈值每2次提供反馈，而不是每次）和（ii）平均汇总反馈（例如，在一个时间段提供正确的百分比）。此外，如果受试者获得高百分比，平均摘要反馈有可能提供积极的反馈 - 这也已知可以增强保留率。为了以门诊的方式应用（i）和（ii），需要比目前可用的更高级的监视和生物反馈平台。我们最近开发了一项基于智能手机的语音卧床监视器（名为语音健康监视器-VHM），用于另一项具有生物反馈功能的NIH资助研究。 VHM将在拟议的项目中使用，以提供三种不同的卧床生物反馈结构，以便整日降低受试者的声音。每次发出声音比生物反馈阈值发声时，都会为对照组（第1组）提供一个卧床生物反馈，第二组（第2组）将每四次发出一次ABSIRATON BIBURATORATY BIAFEEDBACK的声音比生物反馈阈值大声，第三组（第3组）将提供有关其合规性的平均统计数据。假设频率下降（第2组）和摘要平均反馈（第3组）将在与对照组相比关闭生物反馈时更好地保留所需的柔和发音。
