Place it as the final beat of a tribute edit, after a reflective moment and before the closing title card. Pair a gentle sad meow song before it to set the mood, then use this clip as the closing beat.
关于此声音
This is a very short synthetic-voice clip, just over a second long, in which a flat Esperanto text-to-speech voice says a brief farewell to Stephen Hawking. The robotic delivery feels quiet and somber rather than funny, giving the tribute a detached, respectful tone. It was made with an Esperanto text-to-speech bot.
