When children with autism speak they sound different from most people. Their speech usually follows one of several characteristic patterns: Some talk in a flat, toneless voice, others in an exaggerated, hyper way that doesn't match the subject matter.
One particularly rich indicator of social differences in autism is the voice. Children with autism often sound different from other people. Some may speak in a flat, monotone voice; others may use unusual modulation or stress different words or parts of words in their speech; and some may speak at an increased volume.
Many people with autism lack the ability to use prosody and thus have what is often described as a "flat" voice. This is sometimes misinterpreted as a lack of interest, lack of intelligence, lack of humor, or lack of emotional response.
For example, children might: make repetitive noises like grunts, throat-clearing or squealing. do repetitive movements like body-rocking or hand-flapping. do things like flicking a light switch repeatedly.
oddities in loudness, pitch, intonation, prosody, and rhythm. unusually pedantic, formal or idiosyncratic speech. use of metaphor meaningful only to the speaker.
While kids with ASD [High-Functioning Autism] may have begun talking at an appropriate age, they often used a rather long-winded (and sometimes rather concrete or literal) style of speaking. Pedantic describes speech that is overly-focused on the details of its topic.
Vocal stimming, also known as auditory stimming, is self-stimulatory behaviour that involves the use of the mouth, lips and vocal cords. It can also involve the use of ears.
not understanding social "rules", such as not talking over people. avoiding eye contact. getting too close to other people, or getting very upset if someone touches or gets too close to you. noticing small details, patterns, smells or sounds that others do not.
excessive repetitions of phrases, revisions of ideas, filler words such as “um” or “uh” excessive over-coarticulation. Sounds in words run together and sounds or syllables may be deleted. For example, “It's like this” may sound like, “slikethi.”
Though autistic people may respond to emotions and social cues differently than neurotypical people, this does not mean they lack empathy. Just like neurotypical people, levels of empathy vary between autistic individuals.
People with autism spectrum disorder have difficulty interpreting facial expressions. Using a neural network model that reproduces the brain on a computer, a group of researchers based at Tohoku University have unraveled how this comes to be.
We autistic people can't always control our voices so we can speak too loudly or softly and use incorrect pitch tone and speed. Talking normally can require a lot of conscious effort.
Cluttering. There is another language problem found in autism that can produce fast, unclear conversation. Cluttering is when someone talks rapidly, with syllables that run together, excessive filler words and repetitions, and abnormal pauses. It often occurs alongside stuttering, though it's less well-known.
Non-autistic people tend to assess concepts before details, also known as top-down thinking. Autistic people take the opposite approach with bottom-up thinking and use details to build concepts. It may take longer to filter out sensory details with this approach, but you're less likely to miss important information.
Some individuals with borderline autism may be referred to as “high-functioning” autistic. This may because they live independently, function or functioned well at school and/or work, and do not have any observable behaviors such as those exhibited through language or developmental delays.
Defining the Traits and Behaviors of Level 1 Autism
Difficulty switching between activities. Problems with executive functioning which hinder independence. Atypical response to others in social situations. Difficulty initiating social interactions and maintaining reciprocity in social interaction.
If you still hear people use some of the older terms, you'll want to know what they mean: Asperger's syndrome. This is on the milder end of the autism spectrum. A person with Asperger's may be very intelligent and able to handle their daily life.
People with the BAP have some traits common to autism spectrum disorder (ASD), but not enough to have the disorder. But it's not comedians who have drawn scientific scrutiny for having the BAP: it's the parents and siblings of people who actually have autism.
Humming or singing is a common type of vocal stimming. It can be a way for individuals with ASD to regulate their sensory input and cope with the overwhelming environment around them. They may hum or sing a favorite song repeatedly, or create their own tunes.
Stimming can take many different forms: visual: staring off into space, drawing, spinning things like pens or coins. verbal/auditory: repeating sounds, excessive giggling, constantly clearing throat. tactile: rubbing fingers, chewing/biting nails, chewing the inside of cheeks.
