Checking with the community if there is an established way to train dragon to not detect certain sounds as speech. 

I have an issue with dragon hearing the sound of a ventilator as "six" and someone sniffing their nose as "it's". I have tried training these words independently so dragon knows what they do sound like but it's only partially effective. 

 

Any suggestions?

I don't think you'll have luck training non-speech sounds. Approaches that might help, at least a little, include:

1. Reduce the influence of ventilator sounds by increasing the distance between the ventilator and the microphone.

2. Try moving the microphone from one side of the face to the other, so the head acts as a sonic insulator.

3. Try a better microphone and soundcard combination. Some combos do a better job of filtering out background noise than others.

4. Get good at quickly getting rid of unwanted words. The delete [word] command, specifically "delete it's" and "delete six", could become good friends!

Alan, while your suggestions 1-3 are very sound and I would only add one more by mentioning that is always considered best practice to turn off the microphone immediately when you're done dictating, I don't think deleting words such as "it's" or "six" from the vocabulary will do any good, because if you do, Dragon will pick up the ones sounding closest the next time.

It's like bad habits and the negative impact that they have; don't try teaching Dragon to ignore them, but avoid them, or better yet, eliminate them.

Hi Rüdiger,

I agree, deleting the words from the vocabulary would be a bad idea. My suggestion was to learn ways to get rid of unwanted words in the document. The "delete XYZ" and "delete XYZ through XYZ" commands do the job nicely in applications that support the commands. It's handy to be able to delete text without selecting and without moving the cursor.

The first skill I teach new Dragon users is to turn off the microphone immediately after speaking. Unfortunately, there's an exception: When using commands that enumerate matches, e.g., "delete XYZ," "copy XYZ," "bold XYZ" and so on, turning the microphone off dismisses the little numbers.

(Hmmm... Maybe I should toggle off the matching feature initially... From reading this forum, I realize some experienced Dragon uses dislike the feature, but I find it very helpful.)

I have had very good luck using the Nvidia Broadcast noise filtering software, as described in https://www.knowbrainer.com/forums/forum/messageview.cfm?catid=6&threadid=34359.

It does require you to have a middle-end Nvidia GPU.

The post also mentions some other noise filtering software which I have not tried myself.
