Research Abstract |
In this study, we constructed a neuro-computational model by refining the previous physiological articulatory model as a peripheral organ model, where a mapping was established between high-level motor representation to low-level motor representation. The neuro-computational model was confirmed by simulating the speech learning in babbling stage. The results of the vowel learning experiment imply that when perceiving an unfamiliar speech sound, subjects seem to build up a virtual target by projecting the sound to their own acoustic space of the native language, and then approach the target during the learning process.
