Missing Duolingo Aspects
When I use my account, I'm not allowed to view the 'Words' tab. The microphone input doesn't show up at all, either.
I tried logging into a new account that I made, and I'm able to access these options again.
Should I just make a new account and stick with it? Or is this a problem that's already resolved, rendering me inexperienced with solving it or finding the right discussion?
I believe that the Words feature is being tested with a limited number of accounts right now. That could be why you are able to see it on one account but not the other.
As for the sound settings, here are instructions for turning off the audio, you can use them to help you turn the audio back on as well: http://duolingo.wikia.com/wiki/FAQ#Turn_off_audio
If this doesn't solve the issue, please edit your main post and let the tech team know what operating system and browser you're using. (For example, I'm using Windows7/Firefox).
