Objective voice measures may help screen for swallowing problems in adults. This review found specific voice metrics correlate with swallowing function, suggesting potential clinical applications.
Area of Science:
- Speech-language pathology
- Otolaryngology
- Neurology
Background:
- Voice and swallowing share anatomical and physiological properties.
- Research on the intersection of voice and swallowing is limited.
- Objective voice measures may correlate with swallowing function.
Purpose of the Study:
- To explore the literature on the relationship between voice and swallowing measures.
- To investigate if objective voice measures can serve as correlates for swallowing function.
- Focus on healthy adults and those with non-degenerative disorders.
Main Methods:
- Systematic literature search of four databases (Embase, PubMed, CINAHL, Web of Science).
- Inclusion criteria: peer-reviewed, English language, healthy adults or non-degenerative disorders, instrumental/objective voice and swallowing measures.
- Exclusion criteria: case studies, reviews, gray literature, abstract-only studies.
Main Results:
- 11 studies met inclusion criteria out of 5,485 screened.
- Eight studies found an association between objective voice and swallowing measures.
- Significant voice measures included maximum fundamental frequency (F0), F0 range, maximum phonation time, and voice onset time.
Conclusions:
- Specific objective voice measures show promise as a clinical screening tool for dysphagia.
- Heterogeneity in measures necessitates further investigation.
- Validation across diverse patient populations is required.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
