Nonverbal and Nonspeaking in Autism Explained

Defining Nonverbal and Nonspeaking in Autism

At first glance, nonverbal and nonspeaking may appear synonymous, as healthcare providers used it in the past to describe individuals with ASD facing difficulties in communication, but they hold distinct meanings. So, let’s define what means each one:


  • Nonverbal typically refers to individuals who do not use spoken language as their primary mode of communication. These individuals may not rely on speech to convey their thoughts, feelings, or needs.
  • Nonverbal individuals may communicate through other means, such as gestures, facial expressions, pointing, or other forms of body language.
  • It’s essential to recognize that being nonverbal does not necessarily mean a lack of communication ability altogether; rather, it signifies a reliance on non-speech modalities for communication.


  • Nonspeaking specifically denotes individuals who may not use speech but can communicate through alternative means.
  • This term acknowledges that although verbal speech may not be present, there are still avenues for communication available to the individual.
  • These alternative means of communication can include sign language, AAC devices, picture communication systems, typing, writing, or other forms of assistive technology.
  • Nonspeaking individuals may have varying degrees of proficiency and preference in utilizing these alternative communication methods.

While both terms describe individuals who do not use spoken language to communicate, “nonverbal” generally encompasses a broader range of communication methods beyond speech. At the same time, “nonspeaking” explicitly highlights the use of alternative communication modalities in place of speech. Both terms underscore the importance of recognizing and supporting diverse communication abilities within the autism spectrum.

Understanding the Communication Challenges

Some individuals do not develop spoken language in their lifetime, others present a language delay as children, and others prefer to use the blackboard to communicate. Why do these communication difficulties occur in children with autism?

Individuals with ASD experience communication difficulties due to a complex interplay of factors that affect both verbal and non-verbal communication. According to the National Institute on Deafness and Other Communication Disorders, they may have the following communication characteristics:

Neurodevelopmental Differences: ASD is fundamentally a neurodevelopmental disorder, which implies that the brain’s development differs from typical developmental trajectories. These differences can affect various aspects of communication, including language acquisition, the understanding and use of nonverbal communication cues, and the ability to use language in a socially appropriate manner. Neurodevelopmental differences make it challenging for individuals with ASD to process and produce language in the same way their neurotypical peers do.

Challenges with Verbal Communication: Many individuals with ASD find it difficult to develop language skills and understand what others are saying to them. This difficulty can range from the complete absence of spoken language in some to subtle problems with the pragmatics of language—such as understanding idioms, jokes, or sarcasm—in those who are verbally fluent. The inconsistency in language development often results in an uneven skill set, where they may have a rich vocabulary in areas of interest but struggle with general conversational language.

Difficulty with Non-verbal Communication: Nonverbal communication, including gestures, eye contact, facial expressions, and body language, is often particularly challenging for some individuals with ASD. They might not naturally pick up on or interpret these cues, making it hard for them to read others’ emotions or intentions.

Social Interaction Challenges: The core symptoms of ASD include difficulties with social interaction, which directly impacts communication. Individuals with ASD might not recognize social cues that indicate when it’s their turn to speak or when a topic of conversation has changed, making social interactions feel awkward or confusing.

Sensory Processing Issues: Many individuals with autism have sensory processing issues, which can affect communication. Over- or under-sensitivity to sounds, lights, and other sensory inputs can make ordinary environments overwhelming or distracting, hindering their ability to focus on communication. Sensory overload can also lead to distress, making it difficult for them to communicate effectively.

Executive Functioning Challenges: Organizing thoughts, planning, and maintaining attention can further complicate communication for individuals with ASD and make it hard for them to follow conversations, stay on topic, or express their thoughts coherently.

Communication Alternatives for Individuals with ASD

Communication plays a crucial role in our daily interactions, typically involving verbal communication and gestures. However, individuals with autism may have difficulty using these traditional methods of communication. Therefore, it is important to explore alternative means of communication that extend beyond spoken words.
