Hi, I need the best quality, most natural voices. I don't want to buy plan 1 just to find out that all voices sound mechanic and what I really need are the 300 voices only available in Plan 2. Can you please say what voices (in which languages) are missing from Plan 1. Ate the 300 extra AI voices just 'more of the same' or better / more natural voices or customizable voices or something else? Why not include all 1300 AI voices in Plan 1?! cheers!
