KT-Speech-Crawler: Automatic Dataset Construction for Speech Recognition from YouTube Videos (D18-2)
Copied to clipboard
| Challenge: | KT-Speech-Crawler is an automated dataset building tool for speech recognition. |
| Approach: | They propose an approach for automatic dataset construction for speech recognition by crawling YouTube videos. |
| Outcome: | The proposed algorithm can obtain 150 hours of transcribed speech in a day with an estimated 3.5% word error rate. |
Non-Autoregressive Chinese ASR Error Correction with Phonological Training (2022.naacl-main)
Copied to clipboard
| Challenge: | Existing methods to correct ASR errors focus on fixed-length corrections, but rarely consider variable-length ones. |
| Approach: | They propose a non-autoregressive method to correct Chinese ASR errors . they use phonological tokens to extend the source sentence for variable-length correction . |
| Outcome: | The proposed method improves word error rate and speeds up inference by 6.2 times compared with the autoregressive model. |
