Code:

• Train up to 80 words using sigtrain. eg(sigtrain 0 BrunoMars)
• It will train Bruno Mars to position 0 and can be used using load 0.
• While in load when it hears Bruno Mars it will output it in the Serial Monitor.
• You load 7 commands at a time and see how many are in and what values are in load using vr.
• You can clear the load by using clear.
