What this trial studies
This observational study aims to collect data to develop a monitoring technique for dysphagia using voice analysis. It involves a prospective design where patients scheduled for a videofluoroscopic swallow study (VFSS) will record specific vocalizations. Additionally, a control group of individuals without dysphagia will also participate to provide comparative voice indicators. The recordings will be analyzed to assess the relationship between voice characteristics and swallowing function.
Who should consider this trial
Good fit: Ideal candidates include patients with dysphagia who are scheduled for VFSS testing and can perform specific voice recordings.
Not a fit: Patients who cannot speak or follow instructions for voice recording will not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved monitoring and management of dysphagia, enhancing patient care.
How similar studies have performed: While voice analysis for dysphagia monitoring is a novel approach, similar studies in related fields have shown promising results.
