Hello

 

Does running these make a noticeable difference to how well DMPE performs ?

 

I'm using the latest UK version of DMPE 4.3.

 

Thanks

It depends on who you ask. Nuance's heart was likely in the right place but you know what they say about good deeds


There are 3 optimizing possibilities:

1. Increases your accuracy
2. Makes no difference
3. Damages your user profile

We have run into all 3 so we recommend making a backup copy of your ~ C:\ProgramData\Nuance\NaturallySpeaking15\Users\(your username) folder before risking optimizing.

Note: If you believe your accuracy is less than optimal, optimizing will usually help. If you already have high accuracy, with a little luck, you will dodge the bullet but many people have also reported corrupting their user file. We test optimizing on every Dragon release. It never seems to make any difference on our profile but in all fairness, we have been massaging our personal vocabulary, with 3000 entries, phrases and  rules since 1997 (one year before it went public). This likely gives us an edge. Our preference is to take the path of least resistance.

WHat do you mean by "rules" ?

Select any word in the Vocabulary Editor followed by clicking the Properties button. Check out options ranging from Spoken Form to Printed Form to preceded before/after, capitalization context 1 and context 2.

Anecdotal notice won't help, but quantified and reproducible testing on a representative amount of data has proven that it does improve accuracy: in the range of a few percent, at best, however. For the average user this may not be as critical, but for a professional using it as a tool to get his work (texting) done, it does have an impact. While the effect is typically more prevalent during the early stage of a user profile, it will diminish over time.

As a side note: DMPE 4.3 (at least the German version, but I think UK version will be the same) follows the same great idea Nuance had with Dragon 15.5 in moving the speaker profile from %PROGRAMDATA% to %LOCALAPPDATA%.

 

If you're wondering why there is no profile at C:\ProgramData\Nuance\NaturallySpeaking15\Users\<YourSpeakerName> then probably because Dragon moved it to C:\Users\<YourWindowsUser>\AppData\Local\Nuance\NS15\Users, so you have to backup this folder now.

 

Apart from that, I also think Rüdiger's assessment is true. ACO can improve accuracy but other factors (like clear speech and good audio device) usually outweigh these gains.
