You can buy two additional two voices via a $2 in-app purchase. The app tells you you’re buying three voices, but this is a “typo,” say the developers at the bottom of Type n Talk’s App Store page. It seems unlikely that most users will check the app store for this information, however, and it’s unclear why Jirbo has not simply corrected the typo. (Update: After this review was posted, Jirbo contacted us to note that the typo will be corrected in an upcoming update to Type n Talk; the company says that update will also feature Twitter functionality.)
