简要总结
This study examines whether simple speech tasks and a swallowing screening test can help identify swallowing risk in adults of different ages. Participants will complete basic questions, a swallowing self-assessment, a saliva swallowing test, and short voice recordings of rapid syllables. The study is non-invasive, takes about 75 minutes, and may help develop an easy, low-cost screening tool for early swallowing problems.
详细描述
This is a cross-sectional observational study examining the relationship between diadochokinetic (DDK) speech performance and swallowing function in community-dwelling adults aged 18 years and older. Participants will complete a single study visit, during which demographic and health-related information will be collected, the EAT-10 swallowing self-assessment will be administered, the Repetitive Saliva Swallowing Test (RSST) will be performed, and short DDK speech recordings of /pa/, /ta/, and /ka/ will be obtained in a quiet setting. Acoustic features will be extracted from the recordings and analyzed together with RSST and EAT-10 results to explore age-related differences and to develop a predictive screening model for swallowing risk. All data will be de-identified, securely stored, and retained according to study requirements.
