This. Closed caption is almost always wrong. Plus people watch the speeches on FB and other platforms that do not offer CC. I know this because I asked one of the deaf people I know. Most read lips, but that can be hard from different camera angles.Live closed captioning is always a hot mess. If you're not deaf, trying watching a live feed and reading the caption. It's going to be inaccurate or parts of it will be missing.
I don't know sign language. But wouldn't "Do NOT touch your face". Likely have a "NO", and a " face" gesture?? Assuming it's similar to English.The guy here who signs for the governor is always touching his face. Even when the governor is talking about not touching your face.
