Wav2Vec2

Overview
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The Wav2Vec2 model was proposed in `wav2vec 2.0: A Framework for Self-Supervised Learning of Speech Representations
|
|
<https://arxiv.org/abs/2006.11477>`__ by Alexei Baevski, Henry Zhou, Abdelrahman Mohamed, Michael Auli.
|
|
|
|
The abstract from the paper is the following:
|
|
|
|
*We show for the first time that learning powerful representations from speech audio alone followed by fine-tuning on
|
|
transcribed speech can outperform the best semi-supervised methods while being conceptually simpler. wav2vec 2.0 masks
|
|
the speech input in the latent space and solves a contrastive task defined over a quantization of the latent
|
|
representations which are jointly learned. Experiments using all labeled data of Librispeech achieve 1.8/3.3 WER on the
|
|
clean/other test sets. When lowering the amount of labeled data to one hour, wav2vec 2.0 outperforms the previous state
|
|
of the art on the 100 hour subset while using 100 times less labeled data. Using just ten minutes of labeled data and
|
|
pre-training on 53k hours of unlabeled data still achieves 4.8/8.2 WER. This demonstrates the feasibility of speech
|
|
recognition with limited amounts of labeled data.*
|
|
|
|
Tips:
|
|
|
|
- Wav2Vec2 is a speech model that accepts a float array corresponding to the raw waveform of the speech signal.
|
|
- Wav2Vec2 model was trained using connectionist temporal classification (CTC) so the model output has to be decoded
|
|
using :class:`~transformers.Wav2Vec2CTCTokenizer`.
