Article Details


This is a systematic review of published and grey literature investigating the use of the Acoustic Breathiness Index in individuals to assess breathy voice quality.

Questions/Aims Addressed

The following aims were provided:
  • use cross-validation studies to estimate the diagnostic accuracy, sensitivity, and specificity of the Acoustic Breathiness Index; and
  • to calculate an overall weighted threshold of Acoustic Breathiness Index using all included studies.

Conclusions from This Systematic Review

What are Conclusions?

Go to Map


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.
