DDK Acoustic Analysis and Swallowing Indicators

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.
