BIOMEX-DB

This datasets gathers simultaneously acquired records of EEG and voice signals for 51 Spanish-speaking Latinos , 25 female, aged between 16 and 61 years old ( mean: 29.7 SD: 10.9) , 5 declared left-handed, 3 declared ambidextrous, the rest right-handed. Video feed is also available for 39 users.
Users sat in front of a monitor at a distance of approx. 1 m., wearing an Emotiv Epoc headset. Two different session were recorded for each user. For both of them the sequence of events was established as follows: 1) The volunteer is asked to wait for an acoustic signal indicating the recording session start. 2) After the signal is emitted, the user must stay as still as possible, while relaxing with eyes closed for a period of 10 seconds, until the next acoustic signal. 3) Now, with eyes opened, the user must stay relaxed for a second period of 10 seconds. 4) After this, another signal is emitted and a series of non-sequential whole numbers between 0 and 9 is presented on the screen. The user has to pronounce the displayed number. The difference between sessions lies on the length of the numbers series. For the first session, ten digits are presented, whilst for the second one, four digits per chain are presented. 5) After a series is completed, the user is granted a relaxation period of 5 seconds to breath and swallow. 6) The next series is presented 7) steps 4 to 6 are repeated until 10 sequences are completed.
Each compressed file in this dataset includes the records for each of the volunteers, organized in three sub-folders: EEG, Video and Voice. EEG folder includes the EDF and CSV for the recorded sessions. For users for which video records are available, the Video folder includes an MP4 file for each of the series, as well as a .MAT file with the time stamps for the events in the file. Voice folders include .WAV files for each digits-series and their respective .LAB files.

本数据集汇集了51名西班牙语使用拉丁美洲人的同时记录的脑电图（EEG）和语音信号，其中女性25名，年龄介于16至61岁之间（平均：29.7岁，标准差：10.9），有5人自述为左撇子，3人自述为双手并用，其余为右撇子。此外，对于39名用户，还提供了视频流。受试者坐在距离显示器约1米处，佩戴Emotiv Epoc头戴设备。为每位用户录制了两个不同阶段的会话。对于这两次会话，事件发生的顺序如下：1）志愿者被要求等待一个声学信号，以指示记录会话的开始。2）在发出信号后，用户必须尽可能保持静止，闭眼放松10秒钟，直到下一个声学信号。3）接着，用户在睁开眼睛的情况下，必须放松地度过第二个10秒钟。4）随后，发出另一个信号，并在屏幕上呈现一系列0到9之间的非顺序整数。用户需朗读书幕上的数字。两次会话的区别在于数字序列的长度。第一次会话展示了10个数字，而第二次会话则每串展示4个数字。5）在完成一个序列后，用户将获得一个5秒钟的放松期，以呼吸和吞咽。6）接下来，展示下一个序列。7）重复步骤4至6，直至完成10个序列。每个压缩文件都包含每位志愿者的记录，组织在三个子文件夹中：脑电图（EEG）、视频和语音。脑电图文件夹包含记录会话的EDF和CSV文件。对于有视频记录的用户，视频文件夹包含每个序列的MP4文件以及包含文件事件时间戳的.MAT文件。语音文件夹包含每个数字序列的.WAV文件及其相应的.LAB文件。如需更详尽的信息和进一步细节，请联系对应作者。
