Non-autoregressive Error Correction for CTC-based ASR with Phone-conditioned Masked LM

1 code implementation8 Sep 2022 Hayato Futami, Hirofumi Inaguma, Sei Ueno, Masato Mimura, Shinsuke Sakai, Tatsuya Kawahara

Connectionist temporal classification (CTC) -based models are attractive in automatic speech recognition (ASR) because of their non-autoregressive nature.

ASR Rescoring and Confidence Estimation with ELECTRA

no code implementations5 Oct 2021 Hayato Futami, Hirofumi Inaguma, Masato Mimura, Shinsuke Sakai, Tatsuya Kawahara

We propose an ASR rescoring method for directly detecting errors with ELECTRA, which is originally a pre-training method for NLP tasks.

Improving OOV Detection and Resolution with External Language Models in Acoustic-to-Word ASR

no code implementations22 Sep 2019 Hirofumi Inaguma, Masato Mimura, Shinsuke Sakai, Tatsuya Kawahara

Moreover, the A2C model can be used to recover out-of-vocabulary (OOV) words that are not covered by the A2W model, but this requires accurate detection of OOV words.
