Abstract: How are speech features encoded at the neuronal level in the brain? In this talk, I will show how phonetic, articulatory and other speech features are represented by sequences of neural activity in the superior temporal gyrus of the human brain. I will propose that the ordering of these firing sequences organize the encoding of speech features in a neural space, also called a neural manifold, and I will introduce a new method to uncover the neural manifold’s organization during speech processing.
