not sure if this is the right place to ask this, but does anyone know what Sweet Ann and ZOLA are like to use?
Sweet Ann is fun. I use her in V4, for reference. She *was* originally made for V1 and ported to V2 at the last second, so there are some obvious quality blips here and there, but they're not too common. If you're okay with spending some time giving her phonemes some TLC, she can sound really understandable. As with most any Engloid, her hard consonant transitions need the most attention, I will say that.
Something I like to do is try to emulate a glottal stop at the ends of words like "heart" where we don't really say the t, but there's an obvious end to the word -- by putting something softer like a d and then cutting DYN to 0 right at the start of that sound, and Ann gives the best results with that sort of thing, of the 'loids I've tested with it. Someone like Ruby, made for American accented singing, might be a little better to be fair, but yeah. Ann's fun. Get her if you can :)
