🎙️ ACL-25 SpeechIQ Leaderboard
🎯 Welcome to the SpeechIQ Leaderboard!
This leaderboard presents evaluation results for voice understanding large language models (LLMVoice) using our novel SpeechIQ evaluation framework. The Speech IQ Score provides a unified metric for comparing both cascaded methods (ASR+LLM) and end-to-end models.
🥇 | 108.64 | -1.885 | -1.604 | -1.146 | Agentic: ASR + GER + LLM | Whisper_v2-1.5B + GPT-4o + Qwen2_7B | OWSM-CTC_v3.1-1B |
📋 Column Explanations

📊 About SpeechIQ Evaluation
Speech Intelligence Quotient (SpeechIQ) represents a first-of-its-kind intelligence examination that bridges cognitive principles with voice-oriented benchmarks. Our framework moves beyond traditional metrics like Word Error Rate (WER) to provide comprehensive evaluation of voice understanding capabilities.
🎯 Evaluation Framework
SpeechIQ evaluates models across three cognitive dimensions inspired by Bloom's Taxonomy:
- Remember (Verbatim Accuracy): Tests the model's ability to accurately capture spoken content
- Understand (Interpretation Similarity): Evaluates how well the model comprehends the meaning of speech
- Apply (Downstream Performance): Measures the model's ability to use speech understanding for practical tasks
🏆 Model Categories
- Agentic (ASR + LLM): Cascaded approaches using separate ASR and LLM components
- End2End: Direct speech-to-text models that process audio end-to-end
🔬 Key Benefits
- Unified Comparisons: Compare cascaded and end-to-end approaches on equal footing
- Error Detection: Identify annotation errors in existing benchmarks
- Hallucination Detection: Detect and quantify hallucinations in voice LLMs
- Cognitive Assessment: Map model capabilities to human cognitive principles
📈 Speech IQ Score
The final Speech IQ Score combines performance across all three dimensions to provide a comprehensive measure of voice understanding intelligence.
