Open source audio transcription locally in the browser using Web Speech API

A few days ago I needed a browser-based audio recorder with instant transcription locally without any data leaving the client. After 5 minutes of googling I decided to try generating a web app using ChatGPT instead and host it for myself on github pages.

Within a few iterations refining the requirements, I had a working single html file with only a few 100 lines of js code that met all my requirements and was easy to further improve and as a bonus I learned a bit and had some fun optimizing it further the last days.
