scientifically speaking, why do sylvari sound like humans?

@castlemanic.3198 said:The lore (from what I understand) is that the sylvari were shaped from the bodies of Ronin and his family from GW1, meaning that their vocal cords are shaped like human vocal cords, despite being plantlike. their anatomy would theoretically mimic that of a human, and as such, would provide similar results on all fronts, including vocal.

Also, that video you linked is very specifically not the sound of trees talking. Trees blowing in the wind =/= trees actually talking and using human language.

That's what I was thinking. Their anatomy is shaped like humans, magic probably does the rest.
