DDK Acoustic Analysis and Swallowing Indicators (AAP-DDK)
2026년 5월 29일 업데이트: Chen-Fu Hung, Kaohsiung Medical University
Acoustic Analysis of Performance in Diadochokinetic (DDK) Tasks and Swallowing Function Indicators Among Adults Across Different Age Groups
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.

상세 설명
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.

Repetitive Saliva Swallowing Test Classification
기간: Day 1
|
Classification of swallowing function based on the Repetitive Saliva Swallowing Test (RSST).
Participants will be classified as having normal RSST performance if they complete greater than or equal to 3 swallows in 30 seconds, and abnormal RSST performance if they complete fewer than 3 swallows in 30 seconds.
