Language is our most familiar tool, yet its mechanisms are deeply embedded within us, difficult to observe directly. This often makes linguistics, especially phonology, seem abstract. Transforming the intangible process of pronunciation into a visible, operable, and audibly responsive mechanical system is key to breaking down cognitive barriers. By pressing an air bladder to generate airflow, analogous to the respiratory power of the lungs; by using pre-designed tubes of different shapes, analogous to specific oral cavity structures (e.g., a high tongue position and narrow cavity when pronouncing "i," and a low tongue position and open cavity when pronouncing "a"); and finally hearing the corresponding vowel, a complete closed loop is formed from "intentional action" to "physical simulation" to "perceptual result." This multi-sensory (tactile, auditory, visual) learning method can build a far deeper memory and understanding than simply reading text. The "Vowel" exhibit (1468*867*1917m
