Speech
He or she may:
• speak in a monotone voice and/or with unusual or stilted pronunciation; if
he/she appears to have normal language; this may be masking his/her actual
level of understanding
• repeatedly ask the same question or copy/repeat the last phrase they heard
(this is known as ‘echolalia’)
• not respond to questions or instructions
• communicate non-verbally; many people with autism cannot speak
• become noisy or agitated if required to deviate from regular routine
• speak obsessively about a topic that is of particular interest to them, but
which may have no apparent relevance to the situation.
