About this study

participants will be assigned randomly , normal people i will use 2 instruments first : compturized speech lab (CSL) to analyze voice pitch second: electromyography EMG to measure suboccipital muscle tension during speech this task will be repated twice first one during normal speech , second one during change in voice pitch
