Criteria for overall audio quality

The quality of each rating is:

5 - Excellent.
4 - Overall slightly synthetic.
3 - Clearly synthetic but recognizable.
2 - Unclear/unidentifiable sound.
1 - Completely unrecognizable.

Since the generative models were not trained on speech data, they are expected to generate unintelligible speech. Therefore, please DO NOT consider the intelligibility of speech as a part of the criteria (the voice quality can be taken into consideration).

Criteria for audio-text correspondence

The quality of each rating is:

5 - Excellent.
4 - Temporal mismatch or other slight mismatches. E.g., the prompt says one sound after another, but the audio has them simultaneously.
3 - One of the sound components missing/redundant/incorrect. E.g. the prompt requests four sound components, but the audio only has three or vice versa; the prompt asks for one persor speaking but there are two people in the audio.
2 - Missing/redundant/incorrect more than one components.
1 - Totally incorrect.
