I am having an issue where my microphone intermittently produces a static sound, which distorts speech. The static can only be heard when using the Windows Voice Recorder app or whilst speaking in Zoom/Teams, so I am not aware of when the issue is present unless recording my voice whilst dictating in Dragon. 

I have been told that this type of static does not affect the quality of dictation output in Dragon, and the only static that affects output can't be heard in voice recordings, just in the .DRA file playback.

I have noticed dictation output is significantly affected when experiencing static that can be heard in voice recordings, so I would really appreciate any insight into this issue.

Our best guess is sporadic RF interference, loose jack or frayed microphone cable. Other than giving you some ideas, you can only work this out on your end. Consider moving your microphone cable back and forth while dictating into Windows Recorder. It's easy to tell a frayed cable/loose connection from RF interference. If the issue is RF interference, you will have to track down the source which can range from an AC grounding problem, fan, florescent light, oscillating chip etc. Unless you have a frayed cable the problem is unlikely to be your Microphone 

While you can probably dictate, Dragon will have to figure out what you said through the static. This will lower your accuracy and slow your dictation from hitting the page. Note that if you made the mistake of NOT changing Dragon's options, you'll find your microphone slider set to Fastest Response. This setting should only be set for Most Accurate. If you move the slider, your words will be more accurate but probably take considerably longer to hit the page. This just 1 in 3 dozen sandtraps which we pictorially detail in our Dragon Installation/Training Guide

S: According to your user profile you are still using Dragon 15.0. This is a no no. v15.0 is nothing more than a beta version of Dragon. You will find a complimentary download of  v15.61 in your email. Just install it over your existing v15.0
