Analysis Results
Fundamental Frequency (F0): The basic vibration rate of the vocal folds, perceived as pitch.
Jitter: Cycle-to-cycle variation in pitch. Elevated values may indicate vocal instability.
Shimmer: Cycle-to-cycle variation in amplitude. Elevated values may indicate incomplete vocal fold closure.
Harmonics-to-Noise Ratio: Ratio of harmonic to noise components. Lower values indicate more breathiness or hoarseness.
Cepstral Peak Prominence Smoothed: A robust measure of voice quality that correlates well with perceived dysphonia severity.
