how to change the pitch of only the words in a song

i need to find out how to change the pitch in only the words sung in a song. i do not want anything else but vocals to be changed and i havent a clue on how to do it! if anyone knows how tell me.

You can’t. Separating a single recording out into multiple tracks one per part in order to manipulate them is the holy grail of audio processing. It hasn’t been anything like achieved. Without that you can’t apply effects to only some parts in the recording.

oh well. thanks though cause now i wont spend forever tryin to figure out how to do it
