A new arXiv preprint introduces a three-phase iterative pseudo-labeling framework for code-switching automatic speech recognition (ASR), applied here to Mandarin-English mixing. The method generates pseudo-labels from unlabeled corpora, trains a bilingual model in two stages, and iteratively refines it, achieving Mix Error Rate reductions of 6.35% and 8.29% on the SEAME benchmark's devman and devsge subsets. This is the first application of iterative pseudo-labeling to code-switching ASR, addressing the chronic data scarcity problem in this domain.
