Effective communication hinges on a mutual understanding of word meaning in different contexts. The embedding space learned by large language models can serve as an explicit model of the shared, context-rich meaning space humans use to communicate their thoughts. We recorded brain activity using electrocorticography during spontaneous, face-to-face conversations in five pairs of epilepsy patients. We demonstrate that the linguistic embedding space can capture the linguistic content of word-by-word neural alignment between speaker and listener. Linguistic content emerged in the speaker{\textquoteright}s brain before word articulation, and the same linguistic content rapidly reemerged in the listener{\textquoteright}s brain after word articulation. These findings establish a computational framework to study how human brains transmit their thoughts to one another in real-world contexts.
