"Claiming" premium voices is unclear

[juliatuttle]

I found the wording "You can download up to 2 premium voices for use on your devices" unclear -- I assumed it meant I could download up to two voices on my device but erase one to pick another later, not that I could claim up to two voices on my account permanently.

I would suggest using "claim" or "choose" instead of "download", along with a confirmation prompt when the user claims a voice (see #57).
