Claims

C1strongest claim

Harf-Speech attains a Pearson correlation of 0.791 and ICC(2,1) of 0.659 with mean expert scores, outperforming existing end-to-end assessment frameworks.

C2weakest assumption

The 40 utterances scored by three pathologists are representative of the clinical population and that the blended LCS-plus-edit-distance metric faithfully captures the clinical judgment used by experts.

C3one line summary

Harf-Speech delivers phoneme-level Arabic pronunciation scores that correlate 0.79 with certified speech-language pathologists on 40 utterances.
