external vibration device. A prospective, randomized, placebo controlled, single blinded study design will be used to investigate the effects of an external vibration device on voice acoustic parameters and perceptual in MTD patients and singers. The external vibration device to be investigated is the Lelo® Siri vibrator. The external vibration therapy sessions, and pre and post acoustic recordings will be conducted by a SLP.
