Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* 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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Normal group
* A person judged normal among VFSS (video fluoroscopic swallowing study) examiners
* Normal subjects without symptoms of dysphagia
Voice recording before and after dietary intake
* A person who is scheduled to undergo a VFSS test, and his/her voice is recorded before and after eating for the VFSS test
* For general subjects, only voice recordings were conducted before and after food/water intake without a VFSS test.
Residue Group
\- As a result of VFSS (video fluoroscopic swallowing study), the subjects who have residues left around the pharynx or airway
Voice recording before and after dietary intake
* A person who is scheduled to undergo a VFSS test, and his/her voice is recorded before and after eating for the VFSS test
* For general subjects, only voice recordings were conducted before and after food/water intake without a VFSS test.
Aspiration Group
\- VFSS (video fluoroscopic swallowing study) test result, the subjects who have aspiration in the airway
Voice recording before and after dietary intake
* A person who is scheduled to undergo a VFSS test, and his/her voice is recorded before and after eating for the VFSS test
* For general subjects, only voice recordings were conducted before and after food/water intake without a VFSS test.
