Yeah tonight I just realize ffplay can talk lol! ffplay can talk when it have flite capability (see my FFmpeg aoTuV build). It's quite old fashioned and amusing, in ffmpeg it can serve as either for auto narration or as text to speech synth.
Via ffplay just do this:
ffplay -f lavfi flite=text='Whats up Doc?'
Might can be used with zenity as text reader or reminder or whatever fun
