Geometric Signatures of Speech Recognition: Insights from Deep Neural Networks to the Brain

Jiaqi Shang, Shailee Jain, Haim Sompolinsky, Edward Chang · COSYNE 2025

…While brain regions such as the superior temporal gyrus (STG) are known to be involved in speech recognition, how populations of neurons coordinate to enable this process remains unclear. Similar to the brain, state-of-the-art models like Whisper [1] excel at speech processing by transforming acoustic inputs into high-dimensional representations. Such models can thus be valuable tools for studying the neural mechanisms underlying speech perception. In

Human precentral gyrus neurons link speech sequences from listening to speaking

Duo Xu, Jason Chung, Quinn Greicius et al. · COSYNE 2025

…Although the precentral gyrus (PrCG) is traditionally thought to be specific for motor control, we observed neuronal responses in single cortical columns that tiled across listening, delay, initiation, and speaking phases. In contrast, neurons in the posterior Br
