Understanding Vocal Stimming

Who does it?

• Autistic individuals: vocal stimming is more frequent and intense in autism.
• People with ADHD often use vocal stimming to focus or self-regulate.
• Anyone: humming, repeating words, or making sounds can be a natural way to manage emotions or attention.

Why do people vocal stim?

• Emotional regulation: it helps manage excitement, anxiety, or boredom.
• Sensory input: it provides predictable stimulation in overwhelming environments.
• Focus and attention: it can be a tool to concentrate or self-soothe.
• Expression: it is sometimes a way to communicate feelings when words are hard to access.

Should it be eliminated?

Generally, no. Vocal stimming is not inherently negative. Stopping it is mainly considered when it disrupts learning or communication, or when it becomes unsafe, for example very loud sounds that strain the voice.

Best practice is respectful, neuro-affirming support that offers alternatives rather than suppression.

How therapists can help

• Normalise stimming and frame it as a natural coping tool.
• Collaborate across disciplines. Speech and language therapists play a key role, but multidisciplinary teamwork is sometimes needed.
• Offer alternatives, such as quieter or less disruptive vocalisations, when needed.
• Focus on goals, making sure stimming does not block functional development.
