Using DMPE 4 for about a year now. Initially was very happy with accuracy, but in the last few months noticing a lot more inaccurate words/phrases sneaking in. Two different users having the same problem on the same machine. 

Just installed it on another computer, and it is working flawlessly. Still need it on the first one, so I'm wondering--since we didn't change anything on the first one--same sound card, same mike, same software, same location/ambient conditions--what might have changed to lower accuracy? How do we troubleshoot?

                   Welcome to the World's Most Popular Speech Recognition Forum


We used DMPE 4 for 2 years (we are now using DPG 15.5) and didn't experience this problem. Any chance you made the mistake of running Dragon's Accuracy Tuning? That would be one explanation and why our KnowBrainer Dragon Installation/Training Guide details our previous recommendation with 3 dozen others. Gradual lower accuracy means that your user profile is slowly deteriorating and no form of corruption can be fixed à la White House. However, the quickest solution would be to export your vocabulary & commands, create a new user profile and import your vocabulary & commands.

Thanks. I don't recall running Accuracy Tuning, but I'm not certain I never did.

Today it is behaving better, but the problem has been kind of intermittent. If it persists I will apply your suggestion.

Why would something be called "accuracy training" if it make accuracy worse?

Why? Because this process is far from perfect.

 

Users' experience with accuracy training has been very different.

From what I've heard, most users won't notice any or very little improvement, while a few others reported that their accuracy has dropped significantly after this adaptation.

 

So the usual suggestion is: Don't bother and if you do, by all means backup your profile before running adaptation.
