| Challenge: | Automated speaking assessment (ASA) typically involves automatic speech recognition (ASR) and hand-crafted feature extraction from the transcript of a learner’s speech. |
| Approach: | They propose to use metric-based classification and loss re-weighting to model the impact of different SSL-based embedding features on the CEFR score. |
| Outcome: | The proposed model outperforms baselines on the ICNALE benchmark dataset, achieving a significant improvement of more than 10% in CEFR prediction accuracy. |
