The enclosed data is collected using a high-density 256-channel electrocorticography array implanted in a human patient during treatment for epilepsy. The subjects are reading aloud consonant-vowel syllables from a list. The data was collected by Dr. Edward Chang at the University of California, San Francisco, and curated by Ben Dichter. Data is organized by subject ID, and each file is a continuous recording session in Neurodata Without Borders: Neurophysiology (NWB:N) 2.0 format. Voltage traces are included for each of the recorded 256 channels. Microphone signal was recorded at the time but is removed for HIPAA compliance. Detailed hand-marked annotations are provided which mark what syllable was said, and the times of the start, consonant-vowel transition, and end of each syllable. A rest-period time is also included when the subject was silent, which can be used as a baseline. Hand-marked anatomical labels are included for electrodes in the relevant brain regions. All dates have been removed for HIPAA compliance and replaced with Jan 1, 1900.本随附数据集采用高密度256通道皮层脑电图（electrocorticography, ECoG）阵列采集，该阵列植入于一名接受癫痫治疗的人类患者体内。受试者正朗读预设列表中的辅音-元音音节。该数据集由加州大学旧金山分校的Edward Chang博士采集，Ben Dichter负责数据整理与归档。数据集按照受试者ID进行分类组织，每个文件均为采用神经数据无国界：神经生理学（Neurodata Without Borders: Neurophysiology, NWB:N）2.0格式存储的连续录制会话文件。全部256个记录通道均附带对应的电压迹线数据。采集阶段同步录制了麦克风信号，但为符合《健康保险流通与责任法案》（Health Insurance Portability and Accountability Act, HIPAA）的隐私合规要求，该信号已被移除。附带详细的人工标注注释，标注了每个朗读音节的具体内容、起始时刻、辅音-元音转换时刻以及音节结束时刻。此外还包含受试者静默休息时段的时间戳数据，可作为实验基线参考。附带针对相关脑区植入电极的人工解剖学标注信息。为符合HIPAA隐私合规要求，所有原始采集日期均已被移除，统一替换为1900年1月1日。
