paddlespeech.s2t.frontend.augmentor.shift_perturb module

Contains the volume perturb augmentation model.

class paddlespeech.s2t.frontend.augmentor.shift_perturb.ShiftPerturbAugmentor(rng, min_shift_ms, max_shift_ms)[source]

Bases: AugmentorBase

Augmentation model for adding random shift perturbation.

Parameters:

  • rng (random.Random) -- Random generator object.

  • min_shift_ms (float) -- Minimal shift in milliseconds.

  • max_shift_ms (float) -- Maximal shift in milliseconds.

Methods

__call__(x[, uttid, train])

Call self as a function.

transform_audio(audio_segment)

Shift audio.

transform_feature(spec_segment)

Adds various effects to the input audo feature segment.
transform_audio(audio_segment)[source]

Shift audio.

Note that this is an in-place transformation.

Parameters:

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