Question Speech Recognition dll

[jrcarey]

I'm really really new to c# and have been trying to make a Speech Recognition dll for GM studio to use in my game, GM studio is compiled in c++ so after I made a work speech to text program, I tried to do so but without the GUI interface...and it doesn't work, It keeps throwing error in GameMakers compiler, but when I do export it to a dll, the functions have to be static in order to work....is there any way to do this? help please lol
