FBK's Long-form SpeechLLMs for IWSLT 2026 Instruction Following

arXiv:2606.26819v1 Announce Type: new Abstract: This paper describes our submission to the IWSLT 2026 Instruction Following shared task. SpeechLLMs are developed for both short-form and long-form speech instruction following under constrained settings. For the short track, strong performance is achieved on MCIF, with a SIFS score of 2.0708. For the long track, three speech segmentation methods are explored, and the HIFS score is introduced to account for unstable long-form generation. Experimental results show that fixed 30-second segmentation provides the most robust long-form performance, ac

Why this matters
Why now

The continuous rapid advancements in AI, particularly in large language models, are pushing the boundaries of speech processing and instruction following, exemplified by ongoing research competitions like IWSLT.

Why it’s important

This development indicates progress in making AI systems more capable of understanding and executing complex, long-form speech instructions, which is critical for agentic systems and human-AI interaction.

What changes

The ability of AI to handle long-form speech instructions rather than just short commands is significantly improving, moving towards more natural and robust conversational interfaces.

Winners
