DIAL-S2ST adapts Hibiki for adjustable-latency French-to-English speech translation. A frozen teacher provides lookahead predictions while a student with a trainable LoRA adapter learns from its own generated histories; changing the adapter scale at inference adjusts emission timing. On CVSS at 1.8 seconds LAAL, it scores 32.5 ASR-BLEU, ahead of two alternatives, in the evaluated Hibiki setup.
