Abstract
We developed a voice-based, self-paced cursor control task to collect corresponding intracranial neural data during isolated utterances of phonemes, namely vowel, nasal and fricative sounds. Two patients implanted with intracranial depth electrodes for clinical epilepsy monitoring performed closed-loop voice-based cursor control from real-time processing of microphone input. In post-hoc data analyses, we searched for neural features that correlated with the occurrence of nonspecific speech sounds or specific phonemes. In line with previous studies, we observed onset and sustained responses to speech sounds at multiple recording sites within the superior temporal gyrus. Based on differential ..
