Record completeness
Claims
Through a rigorous evaluation of 14 advanced SpeechLLMs, we identify substantial room for improvement in existing models, highlighting meaningful directions for future optimization.
The 5,000 audio-question-answer triplets have been meticulously curated to fairly and comprehensively represent the targeted linguistic phenomena without introducing selection bias or annotation artifacts that would distort model comparisons.
MMSU is a new benchmark with 5,000 curated audio-QA pairs across 47 linguistically grounded tasks that reveals substantial limitations in existing SpeechLLMs for fine-grained spoken language understanding and reasoning.
