Qwen2-Audio quantization performance evaluated beyond text scores

By PulseAugur Editorial · [1 sources] ·

A new study published on arXiv evaluates the performance of quantized Qwen2-Audio-7B-Instruct models on speech tasks. The research highlights that text-based scores alone are insufficient to determine if quantization preserves performance, especially for tasks where target labels cannot be derived from the transcript. The study found that while a 7-bit allocation showed minimal accuracy loss on emotion recognition tasks, a 6-bit allocation resulted in a statistically significant drop in performance, indicating the need for separate evaluations beyond simple transcript accuracy.

IMPACT Highlights the limitations of text-based evaluation for speech models and the importance of task-specific metrics post-quantization.

    Text Scores Do Not Establish Performance on Lexically Non-Diagnostic Speech Tasks: A Qwen2-Audio Quantization Case Study

    arXiv:2609.26823v2 Announce Type: replace-cross Abstract: Text-output scores alone do not show whether quantization preserves performance on speech tasks whose target labels cannot be recovered from the transcript. We evaluate fixed mixed 4/8-bit Qwen2-Audio-7B-Instruct allocatio…
