Plain-Language Brief

The authors introduce AU-Harness, an efficient and comprehensive evaluation framework for Large Audio Language Models (LALMs). The system addresses limitations in existing toolkits by improving speed, providing standardized prompting protocols, and offering flexible configurations for fair model comparison. AU-Harness introduces two new evaluation categories: LLM-Adaptive Diarization for temporal audio understanding and Spoken Language Reasoning for complex audio-based cognitive tasks.

What the Document Says

  • AU-Harness is an open-source toolkit for evaluating Large Audio Language Models (LALMs).
  • The toolkit achieves a speedup of up to 127% over existing toolkits due to optimized batch processing and parallel execution.
  • Standardized prompting protocols and flexible configurations are provided for fair model comparison across diverse scenarios.
  • Two new evaluation categories, LLM-Adaptive Diarization and Spoken Language Reasoning, are introduced.
  • Evaluation across 380+ tasks reveals significant gaps in current LALMs, particularly in temporal understanding and complex spoken language reasoning tasks.
  • Findings highlight a lack of standardization in modalities of user-provided instructions across audio benchmarks.

Raw Abstract / Excerpt

Large Audio Language Models (LALMs) are rapidly advancing, but evaluating them remains challenging due to inefficient toolkits that limit fair comparison and systematic assessment. Current frameworks suffer from three critical issues: slow processing that bottlenecks large-scale studies, inconsistent prompting that hurts reproducibility, and narrow task coverage that misses important audio reasoning capabilities. We introduce AU-Harness, an efficient and comprehensive evaluation framework for LALMs. Our system achieves a speedup of up to 127% over existing toolkits through optimized batch processing and parallel execution, enabling large-scale evaluations previously impractical. We provide standardized prompting protocols and flexible configurations for fair model comparison across diverse scenarios. Additionally, we introduce two new evaluation categories: LLM-Adaptive Diarization for temporal audio understanding and Spoken Language Reasoning for complex audio-based cognitive tasks. Through evaluation across 380+ tasks, we reveal significant gaps in current LALMs, particularly in temporal understanding and complex spoken language reasoning tasks. Our findings also highlight a lack of standardization in modalities of user-provided instructions existent across audio benchmarks, which can lead to performance differences of up to 7.1 absolute points on challenging complex instruction following downstream tasks.
