Fine-Tuning Wav2Vec 2.0 for Downstream Speech Tasks: Accuracy and Sample Efficiency Trade-offs
Abstract
Abstract: This report synthesises findings from 11 peer-reviewed papers addressing the following research question: What is the impact of fine-tuning wav2vec 2.0 on different downstream tasks (e.g., speaker verification vs. language identification) in terms of accuracy and sample efficiency, when evaluated on. 5 claims were extracted from source literature; 5 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 9.0/10. This report is a machine-generated literature synthesis and does not constitute original research.
Research Question
What is the impact of fine-tuning wav2vec 2.0 on different downstream tasks (e.g., speaker verification vs. language identification) in terms of accuracy and sample efficiency, when evaluated on benchmark datasets like VoxCeleb or LibriSpeech?
