 What is ABX Evaluation?
 -----------------------
 The ABX metric evaluates whether a representation X of a speech unit (e.g., the triphone “bap”) is closer to a same-category example A (also “bap”) than to a different-category example B (e.g., “bop”). The ABX error rate is calculated by averaging the discrimination errors over all minimal triphone pairs (ie., differing only by the central phoneme) in the corpus.
+This benchmark focuses on the more challenging ABX across speaker task, where the X example is spoken by a different speaker than the ones in pair (A, B), testing speaker-invariant phonetic discrimination.
