At ASI Wise & Sensory Project, we recognise that understanding how the brain processes sensory information helps us provide the best support for those we work with. A groundbreaking study has revealed that Heschl’s gyrus, a part of the brain traditionally thought to be involved only in early sound processing, plays a much bigger role in understanding speech melody (prosody) than previously believed.
Cortical processing of discrete prosodic patterns in continuous speech
This is important because prosody—the rhythm, pitch, and intonation of speech—helps us engage in conversation, pick up on social cues, and build relationships. Many of the people we support, including autistic individuals, those with ADHD, trauma histories, or sensory processing differences, often find prosody difficult to interpret.
What This Means for Sensory Integration and Everyday Support
It was thought that prosody was processed later in the brain for a long time, but this study suggests that early sensory processing in Heschl’s gyrus plays a key role in understanding speech and meaning.
For therapists and parents, this means:
- Early sensory processing matters: If someone struggles with registering and processing sound effectively, it can impact their ability to interpret tone, emotion, and social meaning in speech.
- Supporting auditory processing can help with communication: Strategies that focus on rhythm, movement, and sound-based sensory activities may help build stronger foundations for understanding speech prosody.
- Speech and social communication are multisensory: Integrating vestibular (movement) and proprioceptive (body awareness) activities alongside auditory input may support early processing of speech patterns and social engagement.
Practical Strategies for Therapists and Families
We can use this knowledge to make a real difference in everyday interactions:
✔ Incorporate rhythm and movement – Activities such as bouncing on a therapy ball, swinging, or marching to a steady beat can help organise the brain for listening and language processing.
✔ Play with pitch and tone – Singing, storytelling with exaggerated intonation, and call-and-response games can help build awareness of prosody in a fun and engaging way.
✔ Reduce background noise – Creating an environment that supports clear auditory processing can make it easier for individuals to tune into speech patterns.
✔ Encourage co-regulation – Many people learn prosody best in interactive and emotionally supportive exchanges, where they can observe and engage with tone and expression in a safe way.
Why This Matters
This research reinforces what many therapists and parents have observed: sensory processing plays a crucial role in communication. When we support how the brain takes in, organises, and responds to sound, we’re not just improving speech—we’re enhancing confidence, social engagement, and participation in everyday life.
We’d love to hear how you’re already using sensory strategies to support speech and social connection.
