thanks your project and I want to confirm that the score range is 0~5?

In general, Mean-Opinion-Score range is 1~5.

SpeechMOS/utmos22_strong score range is designed to be 1~5.
In almost all cases, actual value is in this range.
But, because of implementation, it could be -inf ~ +inf, theoretically (I have never seen this value practically).
