c# - Improve Accuracy Intel Real Sense Speech Recognition -

how can improve accuracy in speech recognition. using commands , dictionary. there more ways improve further. can create audio dictionary such particular audio should recognized particular sentence.

 pxcmspeechrecognition sr;    session.createimpl<pxcmspeechrecognition>(out sr);    // sr pxcmspeechrecognition instance.              string[] cmds = new string[9] { "switch on",                     "light off",                  "up",                  "down",                  "raise",                  "two",                  "three",                  "four",                  "five"               };              // build grammar.             sr.buildgrammarfromstringlist(1, cmds, null);              // set active grammar.             sr.setgrammar(1); 

you can set volume take look

i think if set volume system can recognize better.

as man said , have limit dictionary, careful if there words seem pronunciation , maybe may confuse sound. example :

   public void recognize(){          pxcmaudiosource audiosource = session.createaudiosource();         audiosource.setvolume(1f);         ....        }
