NAVER LABS System Re-implementation for the IWSLT 2026 Instruction-Following Task
arXiv cs.CL 18 hours ago
NAVER LABS implemented a speech-to-text instruction-following system for the IWSLT 2026 shared task using SeamlessM4T-v2-large for speech encoding and Qwen3-4B-Instruct as the language model. The system uses a three-stage pipeline with projector alignment, text-only LoRA pre-training, and multimodal merging, supported by 100,000 synthetic instruction-following examples across ten task types. The model achieved COMET 0.781 on English-to-Chinese speech translation and BERTScore-F1 0.346 on English spoken question answering.
