What is wavlm-large?
WavLM-Large is a state-of-the-art speech processing model developed by Microsoft, designed for comprehensive speech processing tasks. Built on the HuBERT framework, it's pre-trained on an extensive dataset of 94,000 hours of audio from Libri-Light, GigaSpeech, and VoxPopuli sources. The model emphasizes both spoken content modeling and speaker identity preservation, making it particularly effective for various speech processing applications.
Implementation Details
The model architecture incorporates a Transformer structure with gated relative position bias, specifically designed to enhance recognition tasks. A notable feature is the innovative utterance mixing training strategy, which creates overlapped utterances unsupervisedly to improve speaker discrimination capabilities.
