Sorry about the long delay, sort of missed the response!
With the Dhazudak it's roughly 200 words in now with a few tricks of grammar and a unique alphabet. The alphabets I've created for any and all races are always a bit different than the latin one we are accustomed to, thus they have a few random sounds at times - but there's a few key indicators as towards how they are pronounced.
I believe Sámssian is up to 900 words now..
