Vagmi Voice Science Lab

Vagmi Voice Science Lab provides tools for comprehensive acoustic analysis of voice and voice measurements.

Acoustic Analysis of Voice

• F0 and Intensity measure – Mean, Standard Deviation, Fluctuations
• Jitter and Shimmer measurements – Cycle to cycle variations in speech/source
• Harmonic to Noise Ration (HNR)
• Long term average spectrum (LTAS) of voice source; alpha, beta, gamma
• Long term average spectrum (LTAS) of speech; alpha, beta, gamma
• GNE

Voice Measurements

• Voice Initiation and Sustenance
• Maximum Phonation Duration and Jitter (Frame-wise)
• Phonetogram
• Dysphonia Index
• S/Z Ratio (On-line measurement)
• Nasalence (On-Line measurement – requires special hardware developed by VSS)
• Diadacho kinetic rate (DDK) and Rythmicity

This software is useful to Teachers, Students/Researchers and Professionals interested in a study of voice.
