class montreal_forced_aligner.corpus.features.VadConfigMixin(energy_threshold=5.5, energy_mean_scale=0.5, **kwargs)[source]#

Abstract mixin class for performing voice activity detection

Parameters:

use_energy (bool) – Flag for using the first coefficient of MFCCs
energy_threshold (float) – Energy threshold above which a frame will be counted as voiced
energy_mean_scale (float) – Proportion of the mean energy of the file that should be added to the energy_threshold
