About 40% of kids with autism spectrum disorders don’t talk at all, and between 25% and 30% develop some language skills during infancy but then lose them later. Some children with ASD start talking later in life.
Most have some problems with communication, including:
- Delayed speech and language skills
- Flat, robotic speaking voice, or singsong voice
- Echolalia (repeating the same phrase over and over)
- Problems with pronouns (saying “you” instead of “I,” for example)
- Not using or rarely using common gestures (pointing or waving), and not responding to them
- Inability to stay on topic when talking or answering questions
- Not recognizing sarcasm or joking
- Trouble expressing needs and emotions
- Not getting signals from body language, tone of voice, and expressions
