This study describes the manipulation and synthesis of LPC parameters to edit incorrectly produced utterances. In particular, it shows that formant frequencies can be manipulated to produce a consistent and reliable change in perception. It also demonstrates that this method can be used to produce quality synthesis of high-pitched voices.
