A subject voice is characterized and altered to mimic a target voice while maintaining the verbal message of the subject voice. Thus, the words and message are the same as in the original voice, but the voice that conveys the words and message in the altered voice is different. Audio signals corresponding to the altered voice are output, for example to an application for playback to a user, or to another application or device for subsequent playback by the user or someone else. In one embodiment, the altered voice is posted to a social network. In other embodiments, the altered voice is used by other software applications or consumer electronics applications, such as GPS guidance systems, ebook readers, voice-based intelligent personal assistants, chat applications, and/or others that use voice as an input or output.
