A BBC Horizon clip demonstrating the McGurk effect, where the same audio sounds like different syllables depending on the mouth movements you see. It shows that people integrate visual speech information into what they hear.

HN uses it as the standard demonstration that the brain reinterprets perception, in threads on speech, AI audio and illusions.

It was people clapping in mission control but your brain wants to think the sound matches the images so your brain tricks you into thinking it is the sound of water splashing. This is sometimes known as the McGurk effect ▶ this video

Are you talking about the McGurk effect? You hear either Ba or Fa depending on which you expect to hear based on the lip reading (but the sound that is actually playing is Va): ▶ this video It is really cool that small contextual information can change our senses so dramatically without us being aware of it happening.
