Remove verbal content but not voice qualities?

I’m conducting a research study (as a social psychologist) in which we want participants watch and listen to people appearing in video (with audio) clips. In one condition, we want the participants to hear vocal qualities (e.g., female/male voice, pitch) but not be able to decipher what the person is saying. Essentially, we want to garble the content of speech but preserve the tempo and pitch in each video clip.
