  • to calculate an overall weighted threshold of Acoustic Breathiness Index using all included studies.

Population

Individuals with and without voice disorders

Intervention/Assessment

Acoustic Breathiness Index

Number of Studies Included

6

Years Included

2017 to February 2020

Assessment

The Acoustic Breathiness Index (ABI) was indicated to have sufficient to high diagnostic accuracy with high to very high sensitivity (0.84) and specificity (0.92) levels. The high specificity, with low heterogeneity, demonstrated that almost all participants with absence of breathiness were correctly classified as such. Therefore, ABI was revealed to be a robust and valid instrument to objectively measure breathiness.
