vocal-tremor Vocal Tremor

Vocal tremor is measured according to the methods described in this paper by Marcus Bruckl and we highly suggest reading that work to help better understand the variables below.

Raw Variables

Variable Description
mov_freqtremfreq Frequency tremor frequency (FTrF): Frequency of the strongest low-frequency modulation of Fundamental frequency contour.
mov_freqtremindex Frequency tremor intensity index (FTrI): Intensity or magnitude of the strongest low frequency modulation of Fundamental frequency contour.
mov_freqtrempindex Frequency tremor power index (FTrP): Power index of the strongest low frequency modulation of Fundamental frequency contour.
mov_amptremfreq Amplitude tremor frequency (ATrF): Frequency of the strongest low-frequency modulation of Amplitude contour.
mov_amptremindex Amplitude tremor intensity index (ATrI): Intensity/magnitude of the strongest low frequency modulation of Amplitude contour.
mov_amptrempindex Amplitude tremor power index (ATrP): Power index of the strongest low frequency modulation of Amplitude contour.

Derived Variables

Variable Description
mov_freqtremfreq_mean Mean frequency tremor frequency (FTrF): Frequency of the strongest low-frequency modulation of Fundamental frequency contour.
mov_freqtremindex_mean Mean frequency tremor intensity index (FTrI): Intensity or magnitude of the strongest low frequency modulation of Fundamental frequency contour.contour.
mov_freqtrempindex_mean Mean frequency tremor power index (FTrP): Power index of the strongest low frequency modulation of Fundamental frequency contour.
mov_amptremfreq_mean Mean amplitude tremor frequency (ATrF): Frequency of the strongest low-frequency modulation of Amplitude contour.
mov_amptremindex_mean Mean amplitude tremor intensity index (ATrI): Intensity/magnitude of the strongest low frequency modulation of Amplitude contour.
mov_amptrempindex_mean Mean amplitude tremor power index (ATrP): Power index of the strongest low frequency modulation of Amplitude contour.
