Since my PhD days, I've been very interested in the concept of #ZeroSubtitles. They are deliberately omitted #subtitles for utterances considered to be easily understood without them, intentionally incomprehensible, or functioning as sound effects. The decision to omit can be made by the subtitlers or the creatives.

Zero subtitles used to be much more common in countries with a strong subtitling tradition. They often involved very short utterances, usually single words like "Help!", "Yes", "No", or "Thanks." especially from English-speaking content. Nowadays, they are frequently replaced by #GhostSubtitles, a term coined by Jan-Louis Kruger, referring to subtitles that appear for less than one second. They create a "now you see them, now you don't" effect or leave you wondering, "Did a subtitle just flash down there?"

Zero subtitles are not recommended in #SDH, as all the types of utterances above should be represented in the subtitles. One example is [indistinct chatter] when dialogue is used as a sound effect.

Examples of subtitles not meant to be understood sometimes involve third languages ( #L3AVT). Steven Spielberg explains why #WestSideStory does not have subtitles for Spanish: "If I subtitled the Spanish I'd simply be doubling down on the English and giving English the power over the Spanish,"

As for dialogue considered as a sound effect, Christopher Nolan recently offered a defense of his sound design. “There are particular moments in this film where I decided to use dialogue as a sound effect. So sometimes it’s mixed slightly underneath the other sound effects to emphasize how loud the surrounding noise is. It’s not that nobody has ever done these things before, but it’s a little unconventional for a Hollywood movie.” https://lnkd.in/d2y4WQp7

Planning to pitch this concept at #LAM26, if it's still relevant. And I know Patrick Zabalbeascoa will be very pleased.
