Unique: Noise robustness emerges from training distribution diversity (680K hours with natural noise variation) rather than explicit denoising modules — the transformer encoder learns noise-invariant representations through multi-head attention that can suppress noise patterns without separate preprocessing

vs others: Requires no external noise reduction preprocessing (unlike older ASR systems that need Wiener filtering or spectral subtraction), reducing latency and avoiding preprocessing artifacts; more robust than models trained on clean speech due to distribution matching
