Study summary

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.

Inclusion Criteria: * 1.Community-dwelling adults aged 18 years or older, with no upper age limit. * 2.Ability to communicate in Mandarin or Taiwanese and understand the study procedures. * 3.Willingness to provide written informed consent. * 4 .Ability to complete the DDK tasks and RSST. Exclusion Criteria: * 1.Presence of acute respiratory infection, upper respiratory inflammation, or other acute conditions that may significantly affect speech or swallowing. * 2.Impaired consciousness, significant cognitive deficits, or inability to understand the study procedures. * 3.Recent surgery or radiotherapy involving the oral cavity or pharynx that affects speech or swallowing. * 4.Severe hearing impairment that prevents understanding of instructions. * 5.Any other condition deemed unsuitable for participation by the investigators.

Primary outcome measure(s)

  • Repetitive Saliva Swallowing Test Classification — 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.
