This study was designed to identify the physiological vocal parameters of Italian adult subjects by means of Praat software, differentiated by gender and age. The vocal parameters analyzed were mean pitch, Jitter local %, Jitter local absolute, Jitter rap, Jitter ppq5, Jitter ddp, Shimmer local %, Shimmer local dB, Shimmer apq3, Shimmer apq5, Shimmer apq11, Shimmer dda, Harmonicity Mean autocorrelation, Harmonicity Mean noise-to-harmonics ratio, Harmonicity Mean harmonics-to-noise ratio, and the maximum phonatory time.
