TABLE I.
Measures of glottal behavior extracted from GVV estimates obtained from OVV and ACC signals. SID indicates the subject ID number and CAL is a flag that indicates if calibration of skin parameters was performed. Source-related measures are the difference between the first two harmonics (H1–H2), harmonic richness factor (HRF), maximum flow declination rate (MFDR), and peak-to-peak amplitude of the unsteady glottal airflow (AC flow). The fundamental frequency (F0) was observed to be the same for the OVV and ACC signals, so only the latter is presented.
