2Abnormal Tone of Voice

Children suffering from autism spectrum disorder (ASD) often have abnormal voice quality and exhibit speech prosody. Exact mechanisms of these abnormalities are still under investigation. Abnormal voice quality and tone can be improved with speech therapy early in the life of the child. The speech of many children with autism spectrum disorder (ASD) is termed as machine-like or monotonic. Speak with the doctor immediately if you observe any symptoms of autism in your child as early treatment can guarantee best results.
