Abstract -
Parkinson`s disease (PD) is a chronic and progressive neurological disorder that affects the motor system. The muscles to speak and sing from the diaphragm to the larynx are affected. This disease is more common in the elderly people though 5-10% cases can be found with an early onset of 20 years of age. It affects around 6.8 million people globally. Parkinson disease destroys the brain cells which affects the brain related activity. The changes in the brain related activity helps to diagnose Parkinson disease at a stage where vital brain cells are significantly damaged. Voice undergoes a change at an earlier stage before the time the brain cells undergoes changes. Diagnosis at an early stage helps in better and effective treatment and prevents damage of up to 60% neurons that control the movement in the brain. This paper discusses about vocal system and the attributes used in detecting Parkinson’s disease.
