Learning to produce new speech sounds can be a complex process for young children, especially those facing challenges with speech sound disorders or motor planning difficulties. It’s not just about knowing what a sound ‘should’ sound like; it’s about figuring out where to put your tongue, how to shape your lips, and how much air to push out. This is where the power of visual gestures comes in – literally helping children see how to make sounds.

As speech and language therapists, we frequently use visual cues and hand gestures to teach articulation. These techniques are incredibly effective, particularly when a child is struggling with the motor planning aspect of speech production.

In the video clip above you see me teaching

• the /SH/ sound: the hand makes a C-shape and moves forward showing both how the lips are positioned and the air flowing forward
• the /S/ sound: the index finger shows a snake like movement going forward- also showing the air flow again
• the /W/ sound: my right hand moves forward and fingers splay out showing that the lips open up at the end of the sound
• the /K/ sound: my finger points to the back of my throat where the tongue needs to raise.

An overview of motor planning for speech – what do we mean by that?

Think about learning to ride a bike or play a musical instrument. You don’t just know how to do it instantly. You have to plan the movements, practise them, and make adjustments. Speaking is similar! Our brains must:

1. Plan the sequence of movements needed for each sound and word (e.g., /B/ requires lips together, then release, while /T/ requires the tongue tip behind the top teeth, then release).
2. Execute those plans rapidly and precisely.

For some children, especially those with conditions like Childhood Apraxia of Speech (CAS) or other severe articulation disorders, this motor planning process is disrupted. They know what they want to say, but their brain struggles to send the correct, consistent messages to their articulators (lips, tongue, jaw, velum). This can make speech sound learning incredibly frustrating.

Why use visual gestures?

Visual gestures provide an additional, powerful sensory input that can help bridge the gap between knowing a sound and producing it. Here’s how and why they are so beneficial:

1.      Providing a visual map:

• How it helps: Many speech sounds are ‘hidden’ inside the mouth. It’s hard for a child to see where their tongue needs to go for a /K/ sound (back of the tongue to the roof of the mouth) or a /T/ sound (tongue tip behind teeth). A simple hand gesture can visually represent this mouth movement. For example, a hand gesture for /K/ might involve sweeping the hand back towards the throat, while for /T/, it might be a tap on the chin.
• Why it works: Children are highly visual learners. Seeing a physical representation of an abstract mouth movement gives them a concrete ‘map’ to follow, making the process less mysterious and more manageable.

2.      Enhancing motor planning and memory:

• How it helps: When a child simultaneously moves their hand (the visual gesture) and attempts to make the sound, they are engaging multiple sensory systems (visual, tactile, proprioceptive – body awareness). This multi-sensory input strengthens the neural pathways associated with that speech sound.
• Why it works: This multi-modal learning helps to solidify the motor plan for the sound in the brain. It’s like having more ‘hooks’ to hang the information on, making the sound easier to recall and produce consistently. The gesture becomes a built-in reminder.

3.      Reducing cognitive load:

• How it helps: Instead of just hearing the sound and trying to figure out the complex motor sequence, the child has a visual cue to guide them. This reduces the mental effort required to decode the sound production.
• Why it works: When cognitive load is lower, the child can focus more effectively on the specific motor execution of the sound, leading to faster progress and less frustration.

4.      Increasing engagement and success:

• How it helps: Gestures can make therapy more interactive and fun! When a child successfully produces a sound with the help of a gesture, it’s a tangible victory.
• Why it works: Success is a powerful motivator. When children experience success, they are more likely to stay engaged, participate actively, and feel more confident in their ability to learn new sounds.

5.      Supporting self-correction:

• How it helps: Once a child learns the gesture associated with a sound, he or she can use it as a self-monitoring tool. If he or she makes an error, he or she can use the gesture to remind himself or herself of the correct mouth position or movement.
• Why it works: This promotes independent learning and reduces reliance on constant adult prompting.

Conclusion

The journey of speech development can be challenging, but visual gestures offer a powerful and effective tool for teaching new sounds, especially when motor planning is a factor. By providing a clear visual map, strengthening motor memory, reducing cognitive load, and fostering engagement, these gestures pave the way for clearer communication and greater confidence. If your child is struggling with speech sounds, consider talking to a Speech and Language Therapist to get guidance on how visual gestures might be incorporated into the therapy plan. Because sometimes, seeing truly is believing (and speaking!).
