Leveraging Allophony in Self-Supervised Speech Models for Atypical Pronunciation Assessment (2025.naacl-long)
Copied to clipboard
| Challenge: | Recent phoneme classifiers treat allophonic variation as a single phoneme . atypical pronunciation assessment requires distinguishing between a typical and asymmetric pronunciations . |
| Approach: | They propose a new approach that leverages Gaussian mixture models to model phoneme distributions with multiple subclusters. |
| Outcome: | The proposed approach achieves state-of-the-art across dysarthric and non-native speech datasets. |
