Be My Ears:System wide live captions in browser, Zoom, Teams

I work with a colleague who is hearing impaired. He is an amazing guy, we collaborate well for 7 years. One day when we were communicating on Slack, I sent him my favorite video link, and he say it has not been subtitled. Suddenly I realized that I was ashamed of my unintentional offensive behavior. I wondered if I could do something to help him. At the same time, I often experience the benefits of captioning when I watch YouTube videos, but I often find that many valuable videos are not captioned, especially for not-so-popular videos and I feel sorry for them. Therefore, I wanted to have software that could generate subtitles in real-time from the sound in the system.
