Praat script to collect descriptive measures of F0.
Collects a set of descriptive measures of F0 from Pitch objects paired with TextGrids. Measures will be collected for every non-empty interval in a selected tier. Pitch and TextGrid files must have the same name.
- Mean
- Median
- Baseline: 7.4th quantile of the F0 sample (see Reference)
- Standard deviation (SD)
- Coefficient of variation (CV): (SD/mean) * 100
- Quartile coefficient of dispersion: ((Q3 - Q1)/(Q3 + Q1) * 100)
- Median absolute deviation (MAD): median of the deviations from the sample median
- Basedev: median absolute deviation from baseline
- Meandev: mean - baseline
- Range: log2(F0max / F0min) * 12
- Peak rate: rate of F0 peaks per second
- Interpeak duration SD: standard deviation of duration of time between peaks
- Excursion range: median excursion (valley-to-peak) range
Upon running the script, a window like the one below will appear, where the user has to set a number of parameters.
The parameters are:
- Pitch folder and Grid folder: path of folders where Pitch and TextGrid files are stored. They can be the same or different folders.
- Report: path of the folder and name of the file (with extension) of the report outputted by the script.
- Tier: number of the TextGrid tier to be analyzed.
- Smooth: how much smoothing should be applied (the greater the number, the smoother the contour). If set to
0
, no smoothing will be applied. - Interpolation: which kind of interpolation apply in voiceless intervals. Options are no interpolation, quadratic or linear.
- Units: scale of measurement - Hertz, semitones relative to 1 Hz or both.
- Separator: character used to separate columns in the report file - tab, comma or single white space.
