Iterative pseudo-forced alignment by acoustic CTC loss for self-supervised ASR domain adaptation
Iterative pseudo-forced alignment by acoustic CTC loss for self-supervised ASR domain adaptation
High-quality data labeling from specific domains is costly and human time-consuming.In this work, we propose a selfsupervised domain adaptation method, based upon an iterative pseudo-forced alignment algorithm.The produced alignments are employed to customize an end-to-end Automatic Speech Recognition (ASR) and iteratively refined.The algorithm is fed with frame-wise character posteriors produced …
