looping it wont add anything to the model except increase training time

if the intro is 6 seconds, looping to a minute wont increase the quality, as you only get that kind of result with increasing the amount of unique data

Um actually, the intro is 15 seconds. Also, I don't care if it doesn't increase quality. I just got bored and decided to make this model.

is it trained through voicemy.ai? because you can't train anything that's below 1 minute on voicemy.ai. If it's trained through different method then yeah probably unnecessarily but to be fair I've actually did the same thing solely because back then you wouldn't able to train a audio clip below 10 seconds iirc

No, I didn't even know voicemy.ai was even a thing until you mentioned it.

oh
