We employ a combination of recent developments in semi-supervised learning for automatic speech recognition to obtain state-of-the-art results on LibriSpeech utilizing the unlabeled audio of the Libri-Light dataset. More precisely, we carry out noisy student training with SpecAugment using giant Conformer models pre-trained using wav2vec 2.0 pre-training. By doing so, we are able to achieve word-error-rates (WERs) 1.4%/2.6% on the LibriSpeech test/test-other sets against the current state-of-the-art WERs 1.7%/3.3%.

  1. OMAR-RQ: Open Music Audio Representation Model Trained with Multi-Feature Masked Token Prediction

    cs.SD 2025-07 conditional novelty 5.0 of 10

    OMAR-RQ, an open 580M-parameter music audio model trained with multi-codebook, multi-feature masked token prediction on 330k hours, reports leading open-model results on several MIR benchmarks.

  2. ASKD-Whisper: Adaptive Self-knowledge Distillation for Efficient and Low-Latency Automatic Speech Recognition

    cs.CL 2026-01 reject novelty 4.0 of 10

    A distillation method that decays teacher loss then applies self-distillation yields a Whisper-derived ASR model with 5x lower latency and slightly better average WER only on in-domain noisy datasets.

  3. Contextualized Token Discrimination for Speech Search Query Correction

    cs.SD 2025-09 reject novelty 4.0 of 10

    CTD uses BERT token representations plus a composition layer to correct Chinese spelling errors in ASR queries, but the reported gains lack matched baselines and released data.
