Not sure if it helps, but many YouTube videos have transcriptions, unless you mean something other than speech-to-text More on reddit.com

I'd divide the problem into steps. Download the video from the site. There's add-ons for browsers that can download video and save a file locally on your machine, or alternatively there are applications that can just record what's playing on the screen and save to file (this is what people use to pirate Netflix, etc.), or try using the various online video downloader libraries for Python. With the video downloaded to your machine use ffmpeg to extract just the audio. Again this can be a standalone step using the ffmpeg executable from the terminal, or you could use the library in Python. Use a speech recognition library to convert the audio stream to text. Again, plenty of (good) online libraries in Python and some (mediocre, in my experience..) offline ones. Alternatively if you can achieve step #1 on your own, I'm pretty sure there are standalone subtitle apps available. More on reddit.com

(3) max upload per day. Each upload can be up to 30 min https://revoldiv.com/ Online platform. Easy and simple to use. Does not show progress when transcribing so bigger files are hard to track. https://thewh1teagle.github.io/vibe/ Software alternative, upload directly from computer into program and it will transcribe accurately. Shows process percentage. More on reddit.com
