我已经成功地从他们在 MRI 扫描仪中的反应中提取了参与者的明显文字阅读反应时间数据。这是我在 matlab http://www.mathworks.in/matlabcentral/fileexchange/38761-function-to-calculate-reaction-time中编写的函数,但它仅在只有一个语音响应时才有效。当音频文件包含多个人类响应时,它会失败。

我是否正确理解您识别这样的响应:
Step 1: Calculate the average signal height in the set
Step 2: Find the place where the signal is sufficiently higher than the average
在这种情况下,我建议如下:
Start with a small subset (startpoint is the startpoint of the original set)
Do Step 1 and Step 2 for the subset
If nothing is found, increase the subset size and do Step 1 and Step 2 again.
