Homophone Disambiguation Reveals Patterns of Context Mixing in Speech Transformers (2023.emnlp-main)
Copied to clipboard
| Challenge: | 'context mixing' is a feature of Transformers that is used to build up representations of acoustic and linguistic structure in speech models. |
| Approach: | They propose to use a French spelling quirk to probe context mixing in speech models to find out how to translate spoken words into written equivalents. |
| Outcome: | The proposed model incorporates cues to identify correct transcription, whereas encoder-decoder models relegate task to decoder modules. |

Do transformer models do phonology like a linguist? (2023.findings-acl)
Copied to clipboard
| Challenge: | Neural sequence-to-sequence models have been very successful at tasks in phonology and morphology that require a capacity for intricate linguistic generalisations. |
| Approach: | They propose to use a transformer model to model phonological generalisations on 29 different processes . they also use phonology as a primer and a rule with a withheld case to infer behaviour . |
| Outcome: | The proposed model can model all 29 phonological phenomena on a constructed language, regardless of perceived process difficulty. |
