Scholarly reference to this program should be like:
This tool was originally developed to coordinate 4 experimenters in an experiment requiring multiple exact timed steps within 10 minutes. The software uses a text to speech feature and directly addresses different experimenters at defined time points, telling them what to do.
Since such protocols are likely to vary between different labs, it is possible to customize the protocol. This can be achieved by editing the text and hitting the reload button. Each line holds the start time, end time, command, and addressed person.
A working version of the program can be dowloaded here. Unpack the content of the archive (including the subfolder named "Externals") into a single folder and start TalkativeTimer.exe.
