Evidence-based guides on acoustic voice analysis for speech-language pathologists
Single acoustic parameters can't capture the full complexity of voice quality. Learn how AVQI and ABI combine multiple measures into validated scores that correlate with perceptual ratings, plus validated cutoffs for Brazilian Portuguese.
CPP has emerged as the most reliable acoustic measure for detecting dysphonia. Learn why researchers and clinicians are moving beyond traditional jitter/shimmer measurements, and how to interpret CPP values in your clinical practice.
How to get reliable acoustic measurements from telehealth recordings. Protocol recommendations and quality validation.
Understanding the limitations of traditional perturbation measures and when they're still useful in clinical practice.
We're always looking for topics that would help voice clinicians in their practice.
