I have long thought that I would love to voice an animal, monster, or something kind of non-verbal mascot in an anime or video game. It just sounds like such fun to be able to stand in front of a microphone and just make a bunch of silly noises!

Nobody; because I was gonna call but I kept forgetting to

Not a phase; rather I have attempted to dip my toe in periodically. While I do enjoy the creative freedom on display I sadly can't handle the artificial voices for very long. My Vocaloid format of choice outside of covers is Project Sekai versions because the synth voices are more of a fun cameo.
I do love the characters aesthetically though, and own a handful of Vocaloid figurines.

To the point of sometimes not answering them for several days, yes.

Lately I have picked up "Awawawa" as a kind of stim when I'm feeling a bit tired and also in too silly a mood to stop myself doing it. It's like a weird little yawn I do sometimes.

It's always so hard to name solid favourite things. But I suppose it does have to be Halestorm. It's not often that songs speak to me on a personal level, but a lot of theirs do, with their strong themes of being yourself wholly and unapologetically, especially if your identity or proclivities are deemed against the norm.
I think getting into their music when I did was a key factor in properly unlocking my sexuality and identity, because they made me feel safe to do so.

I guess I would probably have to say visiting Japan for my honeymoon. I know, it's very cliche for an otaku to hold up something like that, but it really is an experience that I never expected to be able to have considering how expensive such a holiday can be.

It seems like such a simple answer but honestly? Pokémon.
Outside of being able to pick a magical partner creature to spend my life with (or several if going down the trainer route) the world seems fairly idyllic and a genuinely nice place to live. Technology is reliable, people are mostly friendly, and on the odd occasion where major cataclysms occur, they seem to be very localised and easily solved by some random 10 year old anyway.
I don't think I would even become a trainer. I would just live ab ordinary, happy life with my partner Pokémon. Perhaps I would work at a Pokémon daycare or something.

I was thinking about it, and while I don't usually hold it up as my favourite Final Fantasy, I think FFX might be my favourite game. It's a story that I know very well, and enjoy slipping into again like a comfy blanket, and the gameplay loop is this lovely zen-like flow for me at this point. It's also the first video game to have ever made me physically cry.
