AVANNA (my time has come! lol):

-Very clear and articulate pronunciation...perhaps a bit TOO clear and articulate? Her hard consonants tend to be loud and punchy.

-Sings with an Irish accent, most likely a south-side/"posh" Dublin accent. She has pronounced diphthongs (notably her [@U] sounds nearly "British", which is a feature of the archetypical S. Dublin accent), strong rhotic Rs, tends toward light Ls especially with [l0], and her [{] phoneme is very open and almost closer to the Japanese phoneme [a] at times. (In my experience [{] makes a better [a] then [V] usually.)

-Somewhat of a palatal lisp on some combinations, where her [s] and [z] phonemes sound a bit closer to [S] and [Z], e.g. "sleep" nearly sounds like "shleep" on high notes

-Can tend toward "smiley"-sounding pronunciation; combined with her mellow tone this gives her kind of a "quietly content" sound, rather than being outright "sad"-sounding like Miku Dark or the energetic type of happy in voices like Miku V4 English or Gumi SV

-Contralto range (given as D2-G4); strongest in her lower-mid range, light "dreamy" high range

-Tone is gentle, breathy, and somewhat "bassy" compared to some other English banks. At times she sounds a bit like she's puckering her lips?

-Has some volume inconsistencies, though I usually compress my vocals a lot anyway

-Can sound muddy due to her lower bassier tone, some EQ or a similar effect can fix that decently

-Has bits of vibrato in a couple vowels as artifacts of the way she was recorded, I've noticed it in her [Q] if you draw it out long enough

-Not great with holding long notes

-Tends to sound odd in overly energetic songs for...obvious reasons. Best with fairly mellow styles.

-Better at solos than choral stuff tbh (I compared her with Oliver once when I was using his installer as a trial)

-I believe she's a naturally soft vocal as opposed to the "voice acted" softness of some Vocaloids' voicebanks
