creating the speech recognition application using c++

I have a bit of an interest in this as well. Microsoft provides this functionality in their Speech API ("SAPI"). It interfaces to C++ and .NET languages and makes use of COM.
 
Microsoft has a video here[^] and some good stuff here[^] and here[^] .
 
A list of competing products (Microsoft and otherwise) is available here[^] .
 
I haven't pursued this line too far. I am interested in doing this myself with Java on linux.
 
Good luck!
