Hi, developer on Dictation here.
Sorry it took a while for all of your feedback to get to us. We are not very good at monitoring this forum but we are much better at monitoring direct feedback sent through our built-in feedback system. How do I give feedback on Microsoft 365? - Microsoft Support (as mentioned by Charles a few posts back). TLDR: In your office app, go to help>feedback. Please help us be better in the future by voicing your concerns through our feedback system. If the word "dictation" is mentioned, it gets filtered to our team and someone from our team will be reading through all the feedback.
That said. Can you help us get a better understanding of what you are experiencing? Screenshots like the ones CKGhostWriter uploaded are really helpful for us to see what you are seeing. Other things that are helpful for us are things like: what operating system you are using, which app(s) are you experiencing this in, which version/release of Office you are using (What version of Office am I using? - Microsoft Support), what language/locale you were dictating in, and anything else that you think might be able to help us reproduce the problem on our end. We actually would most appreciate a video of what this looks like on your end, but I also know videos are more time consuming and everyone is so busy with everything already.
After reading everyone's posts, I'm trying to figure out whether the word "Open" appears in Grey or Black on your screen. Grey coloured text indicates that the text is in something we call "intermediate stage", where we are still working on recognizing the phrase that was just spoken but it's not quite finalized. That grey text should turn into black text - which we call "finalized text" - once we have finished calculations. From the screenshots, "Open" definitely happens in Grey text but it also seems like there are instances where the word "Open" will be committed to finalized text. It would be good to get an understanding of whether the mouse was used, the keyboard was used, or if just waiting will turn a grey coloured "open" into a black coloured "open".
I'm sorry this is so frustrating for everyone, but we are trying hard to narrow down which part of the pipeline could have caused this issue so we can fix it for everyone.
Thanks everyone for your patience.
