Evaluation
In a matched reference-free comparison, this adapter reached mean ECAPA speaker similarity 0.6810 and WER 0.0467. The selected full-SFT checkpoint reached 0.6973 and the same WER. The paired ECAPA interval crossed zero, so the objective study did not establish a winner.
One listener preferred this adapter for cadence and long-form listening, with three short-prompt ties. Both releases mispronounced a tested local word. These results do not establish faithful identity cloning, general Singaporean-accent coverage, production fitness, or broad listener preference.
