Combine two voice recognition module

I just thinking that for serial port, how I going to define the commands. Its like this as show below?

          record[0] = group0Record0;
          record[1] = group0Record1;
          record[2] = group0Record2;
          record[3] = group0Record3;
          record[4] = group0Record4;
          record[5] = group0Record5;
          record[6] = group0Record6;

or

case x 11:

break;
case x12:

break;
