Issues with voice control/dictation in Sonoma OS

I mostly use the voice control feature on my work MacBook Pro due to accessibility needs. It was recently updated to Sonoma OS 14.2, and I have noticed the usability of voice control and dictation has reduced significantly. It now no longer recognises when I say "slash" or "forward slash" that I mean for it to add an actual slash, and eat instead add the words. It also does not recognise command such as "numeral one" to add a numeral, and again add the words that are said. In the previous macOS, these commands worked perfectly. The new version also seems much slower than the previous and I have experienced problems that others have noted, such as dictated text being inserted in the middle of a previously dictated sentence, despite the cursor being at the end of that previous sentence before the text was dictated. Another problem that I had the previous version but that has exacerbated in this new version is that despite my language being selected as "English (Australia)" as I am Australian, I often have to resort to speaking with an American accent to have Voice control what I am saying. This is causing huge problems with my ability to work and is of course a massive accessibility issue. It's really disappointing that not only has the voice control feature gone from being better than competitors on windows to being worse, but that there have been so many complaints about the decrease in quality but no improvement has been made.
