Brief summary

this study for investigation of correlation between voice pitch and tension of suboccipital muscles

Detailed description

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
