Overview

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

SEW (Squeezed and Efficient Wav2Vec) was proposed in `Performance-Efficiency Trade-offs in Unsupervised Pre-training
|
|
for Speech Recognition <https://arxiv.org/abs/2109.06870>`__ by Felix Wu, Kwangyoun Kim, Jing Pan, Kyu Han, Kilian Q.

The abstract from the paper is the following:
|
|
|
|
*This paper is a study of performance-efficiency trade-offs in pre-trained models for automatic speech recognition
|
|
(ASR). We focus on wav2vec 2.0, and formalize several architecture designs that influence both the model performance
|
|
and its efficiency. Putting together all our observations, we introduce SEW (Squeezed and Efficient Wav2vec), a
|
|
pre-trained model architecture with significant improvements along both performance and efficiency dimensions across a
|
|
variety of training setups. For example, under the 100h-960h semi-supervised setup on LibriSpeech, SEW achieves a 1.9x
|
|
inference speedup compared to wav2vec 2.0, with a 13.5% relative reduction in word error rate. With a similar inference
|
|
time, SEW reduces word error rate by 25-50% across different model sizes.*

Tips:
|
|
|
|
- SEW is a speech model that accepts a float array corresponding to the raw waveform of the speech signal.
|
|
- SEWForCTC is fine-tuned using connectionist temporal classification (CTC) so the model output has to be decoded using
|
|
:class:`~transformers.Wav2Vec2CTCTokenizer`.
