Researchers have explored new methods for knowledge distillation in automatic speech recognition (ASR) models, focusing on the handling of blank tokens. The study introduces novel blank selection patterns, including a symmetric selection method, which allows for the removal of CTC loss during distillation with minimal performance degradation. This approach could potentially enable distillation on untranscribed audio data, making it more efficient to leverage the strengths of large pre-trained ASR models. AI
IMPACT This research could lead to more efficient training of smaller ASR models, reducing inference costs and enabling broader application of advanced speech recognition.
