I like how easy it is to make my own voices for different characters - you just upload your file in their system which then creates all of its assets (voices) from there! You don't have as much control over them when creating but they do provide some good tools if needed such as pitch correction etc so not too bad at least :) It's great because anyone with access has full rights & ability to use what ever audio files are uploaded without having special permission/approval first. The fact that we only pay $20 per month makes this service ideal since most people want something free or cheap before paying an amount equal to one months worths subscription fee would cost us =D.
