| Challenge: | Existing systems for spoken dialogues do not append question marks to recognized queries . lack of punctuation marks in spoken dialogue can negatively impact comprehension . |
| Approach: | They investigate the impact of question marks on spoken dialogue systems . they analyze examples to determine which types of utterances have the impact . |
| Outcome: | The proposed method shows that question marks have a significant impact on spoken dialogue systems. |
Generating Repetitions with Appropriate Repeated Words (2022.naacl-main)
Copied to clipboard
| Challenge: | Existing studies have focused on general response generation with neural network-based approaches, but none have addressed specific types of repetitions. |
| Approach: | They propose a weighted label smoothing method for explicitly learning which words to repeat during fine-tuning and a repetition scoring method that can output more appropriate repetitions during decoding. |
| Outcome: | The proposed method outperforms baselines in automatic and human evaluations on a pre-trained language model for generating repetitions. |
