What is data2vec-audio-large?
data2vec-audio-large is a groundbreaking self-supervised learning model developed by Facebook that represents a significant step toward unified self-supervised learning across different modalities. This large-scale model is specifically trained on 16kHz sampled speech audio and employs a unique approach of predicting contextualized latent representations rather than modality-specific targets.
Implementation Details
The model utilizes a standard Transformer architecture and implements a self-distillation setup. Unlike traditional approaches that focus on predicting local elements like words or speech units, data2vec-audio-large predicts comprehensive latent representations that capture information from the entire input. The model notably does not include a built-in tokenizer, requiring additional fine-tuning for specific speech recognition tasks.
