Your story reminds me of what's happened to Google's voice recognition over the last five years or so. It used to mis-hear words, but now it actively alters grammar and inserts words that sound nothing like what I actually said. Just try getting it to type the word "o'clock".

At face value, actively altering grammar to words that you didn't say sounds like the language model is very heavily weighed. I'm curious if you mean the keyboard? Because that recently switched to on device I think, which means much smaller models and compute used.

The behavior I'm complaining about happens on both, though as best I can tell the voice typing decides whether to use on-device or cloud-based depending on the conditions when you use it. If you cut your data off you'll get word-by-word recognition, whereas most of the times you're connected the whole sentence will pop in at the same time indicating it used the cloud.
