Chinese-Specific Speech Imagery Coding Using High-Density ECoG

The goal of this study is to investigate whether high-density electrocorticography (ECoG) signals recorded from the surface of the brain can be used to decode neural representations of Mandarin Chinese speech features, including lexical tone, without requiring overt speech movements. The study focuses on the development and evaluation of decoding algorithms based on neural activity recorded during clinically indicated neurosurgical procedures. The main questions it aims to answer are: Can high-density ECoG signals be decoded to reconstruct neural representations of Mandarin Chinese speech fe
