Establishment of Voice Analysis Cohort for Development of Monitoring Technology for Dysphagia

Collection of basic data to develop a technique for monitoring the state of dysphagia using voice analysis.

• Design: Prospective study

• Inclusion criteria of the patient group

  • Patients scheduled for VFSS examination and normal person (without dysphagia) capable of recording voice (selected as a control group for comparison of voice indicators with patients with dysphagia)
  • Patients who can record voices such as "Ah for 5 seconds", "Ah. Ah. Ah.", "umm~~~"

• Inclusion criteria of the control group: Patients unable to speak, Patients who cannot follow along, If the VFSS test is a retest

• Setting: Hospital rehabilitation department

• Intervention: After obtaining the consent form for the patient scheduled for the VFSS test, "Ah for 5 seconds", after clearing the throat, "Ah for 5 seconds", briefly cut with a high-pitched sound, "Ah. Ah. Ah", close your lips lightly and make a "ummm~~~~" sound, and record 2 times each.

Inclusion Criteria:

• Patients with dysphagia and scheduled for VFSS testing
• Patients who can record voice such as "Ah for 5 seconds", "Ah. ah. ah", or "Um~~"
• Normal people (without dysphagia symptoms) who can record voice (additionally recruited for comparison of voice indicators with patients with dysphagia)

Exclusion Criteria:

• Patients who cannot speak.
• Patients who cannot speak according to the researcher's instructions.
• Patients whose VFSS test was reexamined
