Cerebral palsy (CP) is a condition where children have problem controlling their movement, body position and coordination as a result of either retarded development or damage in the brain. Since the disorder is usually caused by a trauma to the brain, the speech function is often damaged as well. Additional problems in communicating can come from the inability to motion or communicate using the body language. Speech is a human express orally through a series of complex movements that alter the basic tone created by voice. So, CP’s speech is a rare and unique from the normal human because of the error of connections between the cortex and other parts of the brain such as the cerebellum. Normal human feels really hard to understand the CP’s speech when they communicate each other. Technology is one of the solutions that can help the CP’s speech problem by creating software that can convert the speech or voice to the text.
