... form of synthesis that incorporates the quali- ties of individual voices is concatenative synthesis. In this type of synthesis, units of recorded speech are appended. By using recorded speech, ... speech, many of the voice qualities of the person recording the speech remain in the resulting synthetic voice. Dif- ferent synthesis systems append different sized 28 segments...
