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.本次随附的数据集通过植入于一名因癫痫接受治疗的人类患者体内的高密度256通道皮层脑电图（electrocorticography, ECoG）阵列采集所得。受试者需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负责数据整理与标注。数据集按照受试者ID进行分类组织，每个文件对应一段连续的录制会话，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。全部256个记录通道均附带电压迹线数据。录制期间曾同步采集麦克风信号，但出于《健康保险流通与责任法案》（Health Insurance Portability and Accountability Act, HIPAA）合规要求，该信号已被移除。数据集附带详细的人工标注注释，用于标记受试者朗读的具体音节，以及每个音节的起始时刻、辅音-元音转换时刻与结束时刻。数据集还包含受试者静默休息的时段数据，可作为实验基线使用。附带针对相关脑区电极的人工解剖学标注信息。为满足HIPAA合规要求，所有原始日期均已移除并替换为1900年1月1日。
