吞咽功能的日常评估和干预，如康复和饮食调整是必要的，以改善吞咽困难。颈部听诊便于卫生保健提供者评估吞咽能力。虽然这种方法允许吞咽声音评估，但用这种方法进行感官评估是困难的。因此，我们的目标是通过结合使用电子听诊器和包含声音识别的人工智能（AI）系统来评估吞咽声音。在此，纳入了20名五年级牙科学生志愿者;每位参与者以不同的姿势（坐姿和仰卧位）喝10 ml水，然后喝20 ml水。我们开发了一种使用AI索引推注流入声音的算法，该算法比较了吞咽声音并创建了一个新的索引。吞咽音的新指数值男性显著高于女性，坐位显著高于仰卧位。声学分析软件证实，男性的吞咽指数明显高于女性，坐姿也明显高于仰卧位。这些结果与使用新指数获得的结果相似。然而，新的指数在姿势方面与有效声压相比，在性别之间存在很大差异。我们开发了一种新的算法，使用听诊器和AI系统来索引吞咽声音，该系统可以识别吞咽声音。对于未来的研究和开发，吞咽困难患者的评估是必要的，以确定新指数的疗效，床边筛查吞咽条件。
Daily assessments of swallowing function and interventions such as rehabilitation and dietary adjustments are necessary to improve dysphagia. Cervical auscultation is convenient for health care providers for assessing swallowing ability. Although this method allows for swallowing sound evaluations, sensory evaluations with this method are difficult. Thus, we aimed to assess swallowing sound by the combined use of an electronic stethoscope and an artificial intelligence (AI) system that incorporates sound recognition. Herein, 20 fifth‐year dentistry student volunteers were included; each participant was drank 10 ml and then 20 ml of water in different positions (sitting and supine). We developed an algorithm for indexing bolus inflow sounds using AI, which compared the swallowing sounds and created a new index. The new index value used for swallowing sound was significantly higher in men than in women and in the sitting position than in the supine position. A software for acoustic analysis confirmed that the swallowing index was significantly higher in men than in women as well as in the sitting position than in the supine position. These results were similar to those obtained using the new index. However, the new index substantially differed between sexes in terms of posture compared with effective sound pressure. We developed a new algorithm for indexing swallowing sounds using a stethoscope and an AI system, which could identify swallowing sounds. For future research and development, evaluations of patients with dysphagia are necessary to determine the efficacy of the new index for bedside screening of swallowing conditions.
