4. Unusual Speech Patterns
Some people with autism may develop unusual speech patterns. Commonly, this will lead to them sounding either monotone and robotic (with less emotion) or alternatively sounding somewhat ‘sing-song’.
In some cases, it may appear as though someone with autism is speaking but their tone of voice is not reflective of the content of what they are saying – almost as though they are not fully understanding the way that others might interpret their speech.
Autism can also cause a number of other quirks and unusual speech patterns. That said, many autistic individuals will speak normally and maybe highly eloquent.
This may be linked with another commonly noticed characteristic of autism: a tendency to pull unusual facial expressions or to gurn or grimace. Again, this can be exhibited to varying degrees depending on the individual.
