ahh never really looked cause i built my original one in 2019 off of Deepspeech haha just updated it for fun mostly. I know youtube captions themselves are good, but one thing on his code would be that not all videos have captions. Since mine actually downloads the audio and runs it, it would still have values on those older videos that never got captions
I searched for my YouTube username and then for the exact title of one video I posted and it didn't find either one.... instead it said the title of my video was not true because it didn't interpret it correctly (but it didn't link to the video).
