• HNR (Harmonics-to-Noise Ratio) [Yumoto et al. 1982]
• CPP (Cepstral Peak Prominence) [Hillenbrand et al. 1994]
• Alpha Ratio [Laukkanen et al. 1997]

Features:

• Instant analysis from 5 seconds of voice
• 3-axis scoring: Stress, Fatigue, Stability
• Daily trend charts
• Full parameter references
