Automatically Evaluating the Human-likeness of TTS Systems via Audio-LLM-Based Score Regression
Auto-ATT is a model that LoRA finetuned on Qwen2-Audio-Instruct and offers a plug‑and‑play pipeline to grade “Audio Turing Tests” (ATTs) at scale, producing objective scores that correlate with human judgements––all without manual listening.
About Audio Turing Test (ATT)
ATT is an evaluation framework with a standardized human evaluation protocol and an accompanying dataset, aiming to resolve the lack of unified protocols in TTS evaluation and the difficulty in comparing multiple TTS systems. To further support the training and iteration of TTS systems, we utilized additional private evaluation data to train Auto-ATT model based on Qwen2-Audio-7B, enabling a model-as-a-judge approach for rapid evaluation of TTS systems on the ATT dataset. The datasets and Auto-ATT model can be cound in ATT Collection.
