Secure text-to-speech synthesis for portable electronic devices

摘要

A method for secure text-to-speech conversion of text using speech or voice synthesis that prevents the originator's voice from being used or distributed inappropriately or in an unauthorized manner is described. Security controls authenticate the sender of the message, and optionally the recipient, and ensure that the message is read in the originator's voice, not the voice of another person. Such controls permit an originator's voiceprint file to be publicly accessible, but limit its use for voice synthesis to text-based content created by the sender, or sent to a trusted recipient. In this way a person can be assured that their voice cannot be used for content they did not write.
