In my case, it always been garbage. Speech to text doesn't require AI when you do it like Microsoft did it in the aughts; ever since "new, better", cloud-side techniques came along, the technology got worse, and the only meaningful qualitative improvement I've seen in two decades is in the last two years, with new-generation models which may or may not be backed by LLMs now.
Over time its become worse, but all of Googles products have become worse. That doesn't mean it we couldnt do it, we just can't rely of Google to provide it.
