Child-Adapted Structured Phonological Representations for Interpretable Speech Sound Analysis

Structured phonological representations provide an interpretable alternative to generic speech embeddings, but existing models are largely trained on adult speech. We adapt PhonoQ-2.0 to child speech using CHILDES-Aligned data and compare three alignment-supervision conditions (Adult, Adult+Child, and Child-only) acros...

Structured Phonological Representations for Audio-Articulatory rtMRI Speech Classification

Preliminary analyses show interpretable surface-sensitive patterns consistent with flapping-like /t/ realizations, /t/-/r/ retraction or affrication, and nasal place assimilation, indicating that phonological information from synchronized audio can be partially transferred to articulatory models.
