paddlespeech.s2t.frontend.augmentor.speed_perturb module

Contain the speech perturbation augmentation model.

class paddlespeech.s2t.frontend.augmentor.speed_perturb.SpeedPerturbAugmentor(rng, min_speed_rate=0.9, max_speed_rate=1.1, num_rates=3)

Bases: AugmentorBase

Augmentation model for adding speed perturbation.

Methods

__call__(x[, uttid, train])	Call self as a function.
transform_audio(audio_segment)	Sample a new speed rate from the given range and changes the speed of the given audio clip.
transform_feature(spec_segment)	Adds various effects to the input audo feature segment.

transform_audio(audio_segment)

Sample a new speed rate from the given range and changes the speed of the given audio clip.

Note that this is an in-place transformation.

Parameters:

audio_segment (AudioSegment|SpeechSegment) -- Audio segment to add effects to.
