RASST: Retrieval-Augmented Simultaneous Speech Translation

arXiv:2601.22777v2 Announce Type: replace Abstract: Simultaneous speech translation produces target text incrementally from partial speech input. Recent speech large language models have markedly improved SST quality but still struggle with rare and domain-specific terminology. Retrieval augmentation has helped in automatic speech recognition and neural machine translation, but extending it to SST is non-trivial: retrieval must be fast and accurate under partial speech, and the model must decide whether and when to apply retrieved terms during incremental generation. We propose Retrieval-Augme

Why this matters
Why now

The rapid advancements in large language models and the increasing demand for real-time, accurate, and nuanced AI applications are driving innovations like RASST. This research addresses critical limitations in existing simultaneous speech translation systems.

Why it’s important

Improving simultaneous speech translation for rare and domain-specific terminology has significant implications for global communication, intelligence gathering, and specialized industry applications.
