You could do this very easily with LiVES. Simply load each video clip in
turn and then save it as a clip set.

Reload the clip set and the user can play the first clip. Then after
playing they can select the next clip (ctrl-page-down, or with mouse wheel
or from Clips menu, etc).

You could of course create a small script which detects a voice command
and sends a /clip/select command followed by a /video/play command.
