@Lady Juliette, If your tallents are in writing, I suggest having a look at choiceofgames and considering games using their choice script language, Their website is here and you can find tutorials on choice script there.
I'm not sure if you could make enough to actually live on, but you could write your games with a pretty good parser and get them sold successfully.
They would be utterly %100 accessible to audiogamers, but would be released to the general public too, you might even get a headstart on a writing career that way as well.
Btw, I, ---- and likely Sander and Richard too are probably the closest thing we have to people who work full time in the audiogames industry, indeed I tend to consider what I do for this site as a job, or at least as voluntary work.
It's actually listed on my Uk benefits application as part time volunteering, one reason I try my best with db updates etc.
Sander was kind enough to say he'd like to pay me, but the game accessibility special interest group doesn't have the cash.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
