Aging and Parkinson's disease prosodic-acoustic parameters results

The parameters are: coefficient of variation of intensity (cvint), mean of the standard deviation of negative F0 (dF0negmean), mean of the standard deviation of positive F0 (dF0posmean), standard deviation of negative F0 (dF0sdneg), standard deviation of positive F0 (dF0sdpos), pause duration (durSIL), spectral emphasis (emph), maximum F0 (F0max), median F0 (F0med), minimum F0 (F0min), F0 peak rate (F0peak_rate), F0 peak distance (F0peak_width), semi-amplitude of F0 quartiles (F0SAQ), standard deviation of F0 (F0sd), harmonics-to-noise ratio (HNR), inter-pause interval (IPI), jitter, shimmer, standard deviation of F0 peaks (sdF0peak), standard deviation of F0 peak positions within the segment (sdtF0peak), LTAS spectral slope of high and low frequencies (slLTAShigh and slLTASmed), and articulation and speech rates.
