MP3 auditions of a new voice and, once you pick one, a saved voice id you can reuse.
About
Creates a new voice from a description of age, gender, accent, timbre, pace and character. It works in two steps. Preview writes up to three short MP3 auditions of the voice speaking a sample line (your own, 100 to 1,000 characters, or one the provider writes). Save keeps the audition you chose and returns a permanent voice id that a voiceover tool can then speak with.
It is for giving a brand or a character its own voice instead of picking one from a stock list. Auditions are saved to a shared voices folder by default, so they outlive any one project.
Preview is a paid model call, billed by the length of the sample line. In Syvon a typical preview call costs between $0.04 and $0.42. Saving costs nothing, but it adds a voice to the provider account, where that account's voice limit applies.
