Cepstral Emily 

Cepstral Emily is a text to voice add-on for the SwiftTalker application. You can open any text file and play using the "Emily" voice. Speech can be controlled using the transport control buttons found on the toolbar near the bottom of the SwiftTalker window. You can use these controls to Play, Pause, and Stop speech. They also allow you to skip forward and backward through text and jump to the beginning and end of the document.
