From hums and whistles to repetitive clicks and quotes, vocal stimming is a common way for neurodivergent individuals to self-regulate. In this post, we dive into the reasons behind vocal stimming, whether it’s a cause for concern, and how to support neurodivergent staff who stim at work.
“Vocal stimming”, short for vocal self-stimulatory behaviour, is when a person uses repetitive sounds from their mouth or lips to self-regulate. For many neurodivergent individuals, it’s a tool to manage sensory input, express themselves emotionally, self-soothe, or enhance attention.
Vocal stimming is a common practice for people with autism, who may perform vocal stims alongside other physical stims like handflapping, rocking, or blinking. All of these behaviours serve a similar purpose: to regulate the nervous system.
There are lots of different kinds of vocal stims, and these can range from more subtle vocalisations to more obvious ones. Common types include:
While all human beings have the capacity to stim physically or verbally, people with autism, ADHD, and other types of neurodivergence are more likely to do so due to fundamental differences in how their brains process the world around them. These differences can also vary depending on the type of neurodivergence they have, which means stims can serve different purposes.
Roughly 44% of autistic individuals stim. For adults with autism, vocal stimming is commonly used to manage sensory input and create familiarity and predictability. Stims may occur at any time, whether someone feels calm and happy or stressed and upset; however, the primary goal is to keep sensory and emotional experiences steady and comfortable.
In ADHD, stimming is more about self-regulating dopamine and increasing stimulation. Stims may be used to help someone feel more focused or alert when they feel restless or bored. This might be during an unstimulating activity or when they feel mentally tired. Making sounds or repeating words can give the brain a bit more stimulation, helping it to stay engaged and energised.
Vocal stimming most often happens in conditions where repetitive motor patterns, sensory regulation differences, or tic‑like behaviours are key features. This means that individuals with genetic neurodevelopmental conditions such as Fragile X syndrome, Rett syndrome, and Williams syndrome may also engage in vocal stimming, though the form and frequency can vary by condition.
It completely depends on the individual. Although some people with neurodivergence may choose to mask stimming behaviours, many autistic adults report that stimming is a helpful way to communicate or self-soothe, and see it as largely harmless. This is even more true for vocal stims, since they’re less likely to involve self-injury.
For those who choose to stop or cut back, suppressing stims may come from a fear of judgment. Someone with very obvious stims might aim to behave in ways that they feel are more socially acceptable or professional, or they may realise their behaviour is disruptive and try to reduce its impact on others.
Most of the time, vocal stimming isn’t a cause for concern. However, it should be managed by a professional if it poses a risk to the person stimming or the people around them. For example, if someone is clenching their jaw, coughing to the point of injury, or repeating offensive or abusive language.
So, how can you support an employee who wants to regulate their stims? Firstly, it’s important to remind yourself that this isn’t about erasing someone’s natural communication style or trying to help them “pass” as neurotypical. You can support someone to helpfully regulate their stims by working with them to define clear, healthy intentions for stopping or cutting back. Consider:
Although vocal stimming in the workplace can be a tricky thing to manage, one of the most important things you can do as an employer is to normalise neurodiversity and model inclusive workplace attitudes. Workplaces where certain topics are taboo or where people feel pressure to hide their needs can increase stress and push employees into masking, so try to be as open and supportive as you can.
After some safe, practical alternatives to workplace stimming? When it comes to regulating vocal stims, stopping cold turkey isn’t advised. You need supportive options and sensory accommodations in place. Focus on the following:
Instead of getting someone to avoid their preferred sounds, encourage them to try alternatives like closed‑mouth humming, whisper‑level scripting, or soft vowel sounds. These will keep the same rhythm and regulation without carrying across the room.
Speak to your employee about swapping vocal stims for movement-based alternatives. Could they benefit from fidget tools, textured objects, rhythmic foot tapping, or gentle rocking? These can provide predictable input without relying on vocal noise.
Encourage your staff member to use breath-based techniques like patterned, diaphragmatic breathing or gentle sighing for grounding and consistency in a quieter way. These can also have a positive calming effect if the employee is experiencing stress.
For more in-depth, focused work, offer them a private work booth or office that they can use to stim freely without worrying about disrupting others. Be sure to consider any additional sensory tools or assistive technology they may need to knuckle down without distractions.
Nope. Although stimming can happen when someone is distressed, it can also happen when someone is calm, focused, excited, overwhelmed, or even just because “they feel like it”. Stimming is a regulatory tool, not an automatic sign of struggle.
Not quite. While some vocal stims can appear similar to tics, they’re not the same. Stimming is usually intentional or semi‑intentional and helps someone regulate, while tics are involuntary movements or sounds.
Generally, no. Drawing attention to stimming can increase self‑consciousness and lead to masking. If someone has asked for support regulating their stims, follow their lead. Otherwise, it’s best to let them stim without comment.
Absolutely. Simple adjustments like flexible seating, headphones, quiet zones, or normalising varied communication styles can make a big difference. Most accommodations are low‑effort and high‑impact for everyone involved.
