For years, I been using a seperate audio to text captioning application and overlaying it over the browser because I am Deaf since birth. It uses Google API to convert audio to text since Google seems to have the best audio AI with around 98% efficiently.
Until Google finally add this as part of Chrome browser extension which is about time too. No more fumbling to set up the software bridge to link the audio out to the audio ti text application.
Here a screenshot of Joe's today live ... you can see the overlay captioning in the screenshot which is now part of the Chrome built in captioning overlay.
And Apple just released iOS16 which have audio to text captioning overlay but strangest thing is won't pick up in a screenshot when I tried to take a picture of it. The audio AI at Apple doesn't seem that great and have a much lower efficiently compared to audio AI at Google thou but that understandable since Google AI have a much longer learning time over years and billions of youTube to learn from. The first 3 years, Google audio AI were terrible so Apple will probably get better with time since Apple audio AI work on every app on Mac not just "browser" but every app that is speaking which kind of make it cooler.
