Research Paper Overview
Chunk Based Speech Pre-training with High Resolution Finite Scalar Quantization
Summary
This paper proposes a chunk based self-supervised learning algorithm for speech pre-training that works for both streaming and offline modes. It uses masked prediction loss and a finite scalar quantization module with a high resolution codebook to discretize speech features. A copy and append data augmentation method and group masked prediction loss reduce memory and computation costs. The approach is validated on speech recognition and translation tasks, showing competitive results on Librispeech and Must-C datasets.
