Researchers have developed a novel multi-task learning framework to improve phoneme recognition in non-canonical speech, such as that found in pathological conditions or accents. This approach decomposes phoneme prediction into articulatory features like manner, place, and voicing, using a hierarchical architecture with cross-attention fusion. The system also incorporates semi-supervised learning and a staged training strategy to handle limited and noisy clinical speech data. Experiments on a proxy dataset demonstrated significant performance gains over baseline models, offering interpretable error patterns aligned with phonological features. AI
