Figure 1.

Neural data recorded during a word speaking task.

(A) Array placements on 3D reconstructions of each participant’s brain. The left side illustration highlights that we recorded neural correlates of overt speech in a dorsal cortical area that is distinct from the ventral areas where speech production is typically decoded. (B) Illustration of the visually-prompted word speaking task. (C) Example phoneme segmentation of a word from the recorded audio. Below we show threshold crossing spikes and high frequency LFP (HLFP) for a 500 ms window rates centered on voice onset for this utterance of /w/.
