TISE Dataset-Thai Script for Imaginary Spelling using Electroencephalogram Signals

Thai Script for Imaginary Spelling using Electroencephalogram (TISE dataset) is related to pronunciation/spelling and imagination of Thai vowel script based on electroencephalogram (EEG) signals. This dataset consists of character spelling (CS) and character imagination (CI) datasets. Providing CS and CI datasets is very important to ensure that the EEG signal patterns of spoken scripts are by imagination. So, this dataset needs to be provided. In addition, previous researchers have yet to collect Thai script imagination datasets. The participants used as samples in this study were 33 healthy people, 25 males, and eight females, from Thai students at the Rajamangala University of Technology Thanyabur. The participants' EEG signals were recorded using Contec KT 88 with 16 channels. This dataset consists of 4 types of data: (1) Raw data for experiments, (2) Raw data for calm conditions, (3) Data analysis for Character spelling, and (4) Data analysis for Character imagination. Data analysis for Character spelling and Character imagination was generated from the combined data (joined_data) for eight Thai vowel characters based on the timestamp of the characters' appearance. Also attached is the Ethical Clearance.pdf file related to the research permit from the Ganesha University of Education ethics committee. The Stimulus media.mp4 file is the stimulus media file used during the experiment, while the Timestamp Thai script.pdf file contains the duration of the Thai characters' appearance.

基于脑电图的假想拼写泰语脚本数据集（Thai Script for Imaginary Spelling using Electroencephalogram，简称TISE数据集）围绕基于脑电图（electroencephalogram，简称EEG）信号的泰语元音脚本的发音/拼写与想象任务展开。本数据集包含字符拼写（character spelling，简称CS）数据集与字符想象（character imagination，简称CI）数据集两类子数据集。单独提供CS与CI两类子数据集，可确保所采集的语音脚本脑电信号模式确实源于想象过程，因此本数据集的完整发布具有重要意义。此外，目前尚无前人开展泰语脚本想象任务的脑电数据集采集工作。本研究的受试样本为33名健康志愿者，其中男性25名、女性8名，均为泰国塔尼布里皇家理工大学的在校学生。受试人员的脑电信号通过16通道Contec KT 88设备采集录制。本数据集共包含四类数据：(1) 实验原始数据，(2) 静息状态原始数据，(3) 字符拼写任务分析数据，(4) 字符想象任务分析数据。字符拼写与字符想象任务的分析数据，均基于8个泰语元音字符的呈现时间戳，由对应联合数据（joined_data）处理生成。随数据集附带了由格涅沙教育大学伦理委员会出具的研究许可伦理批准文件Ethical Clearance.pdf。实验刺激媒体文件Stimulus media.mp4包含本次实验所用的刺激素材，而Timestamp Thai script.pdf文件则记录了泰语字符的呈现时长。
