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.
Children with autism spectrum disorder (ASD) who can speak often exhibit abnormal voice quality and speech prosody, but the exact nature and underlying mechanisms of these abnormalities, as well as their diagnostic power are currently unknown.
Low muscle tone is commonly seen in children with autism. However, since ASD is a spectrum, their physical presentation can vary drastically from having increased tone which is causing the tip-toe walking, to decreased tone and walking either with flattened feet or compensating by going up onto their tiptoes to walk.
“[Adults with autism] tended to be louder when they were speaking, and they also took a longer period of time to say the statements than the controls.” When listening to the recordings, the adults on the spectrum had more trouble inferring emotion than the controls did, but, interestingly, their speech conveyed more ...
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.
oddities in loudness, pitch, intonation, prosody, and rhythm. unusually pedantic, formal or idiosyncratic speech. use of metaphor meaningful only to the speaker.
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.”
Words that may seem neutral can become provoking if spoken with a sarcastic, demeaning or contemptuous tone of voice, causing the listener to feel hurt and disrespected. A soft tone of voice is often interpreted as lack of confidence – but too loud, and you'll be seen as aggressive.
Autistic people may also be able to hear sounds from inside the building – such as voices or noises from other rooms, or water in pipes and electricity in the walls. A decibel meter can be useful to support this work (now available as a phone app for those in need).
Communication can be characterised by very limited use of language or they may use it excessively, they may have a 'flat' tone to their voice and repeat certain phrases over and over. They might talk 'at' others rather than having a 'back and forth' conversation, or talk mostly about their topics of interest.
One of the most common is monotonous speech. This means that they may speak in a flat, monotone voice. They may also use the same pitch and inflection regardless of the situation. Another common speech pattern in toddlers with Asperger's is stilted speech.
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.
Stimming is a way for individuals with ASD to regulate their sensory input and cope with the overwhelming sensory environment around them. Vocal stimming can take many forms, such as humming, singing, making animal sounds, repeating words or phrases, and more.
The prosody of ASD speech has been variously described as sounding “robotic,” “wooden,” “stilted,” “monotone,” “bizarre,” “over precise,” and even “singsong” (Fay and Schuler, 1980; Baltaxe and Simmons, 1985; Frith, 1991; Baron-Cohen and Staunton, 1994).
Stilted speech: odd language use that may be excessively formal, pompous, outdated, or quaint. Self-reference: The patient is liable to refer the subject of conversation back to him/herself.
Main signs of autism
finding it hard to understand what others are thinking or feeling. getting very anxious about social situations. finding it hard to make friends or preferring to be on your own. seeming blunt, rude or not interested in others without meaning to.
Symptoms. Like all people on the autism spectrum, people who are high functioning have a hard time with social interaction and communication. They don't naturally read social cues and might find it difficult to make friends. They can get so stressed by a social situation that they shut down.
People with autism often speak with a different rhythm, prosody, and/or volume than typical peers. Thus, even if the words themselves are appropriate, they may sound flat, loud, soft, or otherwise different. It's not unusual for people with autism to "script" their conversations.
It should be noted that though kids with Asperger's don't usually have language deficits-they can be very talkative, in fact-many on the autism spectrum do have difficulty communicating verbally, which is partly why new diagnostic criteria will stress social communication deficits and restricted interests.
People diagnosed with autism normally use idiosyncratic speech that make little sense to those who are not familiar with them. These individuals also use odd tones, where the speeches are characterized by rises at the end of sentences and are rather monotonous.
