Measures
MPT (Maximum Phonation Time): measures the duration of sustained vowel phonation. Reflects respiratory support and vocal fold efficiency.
DSI (Dysphonia Severity Index): combines 4 acoustic parameters into a single validated score for overall dysphonia severity.
- • MPT - Maximum Phonation Time
- • F0-High - Maximum fundamental frequency (from pitch glide)
- • I-Low - Minimum sustained intensity
- • Jitter Local - Cycle-to-cycle period variation
