That happens in most speech to text systems, even Superwhisper, Monologue and Wispr Flow. I read somewhere it comes from training on YouTube audio and happens when there is silence. I guess it depends on the model but most of them are based on Whisper which has this problem

Does it also insert "please like & subscribe?"

Ha, I also have this happen all the time in response to mouse clicks. When playing with Apple Foundation Models + Whisper I noticed that it happens so often that I had to explicitly filter this out before acting on transcriptions.
