I have Iroha, Minato, Crimmzoh, and Rice-chan. I checked and all of them have the same number of voice models as before. (Last time I posted, I thought the number had changed, but I was wrong.)
I never posted it in here, but I did record myself saying the same sentence with each character/each model in this tweet thread:
So today, I have recorded a new tweet thread with new recordings and I think it has improved quite a bit!
There is a problem with the audio that is only noticeable with headphones (each time I talk, there is a loud burst of "air" that kind of hurts your ears, I tried changing the settings for Voidol and my mic but nothing made it go away). It sounds actually pretty fine on normal speakers, though.
The mechanical gargle sound from before seems to be for the most part gone. (The results still aren't perfect, but this is significantly better than before in my opinion.)
I also want to test out speaking in Japanese/singing, but not at this moment.
