This is an early manifestation in many people with Parkinsons disease that the voice may be a little bit more monotone in it's quality, less inflected. All of us, again, as we speak we have this sort of normal up and down to our voices, and that can be changed in people with Parkinsons disease. It's more of the same tone throughout. Also, volume can be affected so that a person's speech can be reduced in volume, and they're asked to repeat things more often.
