What is the best way to make a voice activated switch?

I am trying to make an electric airsoft gun fire on my comand. What is the best (and cheapest) way to make something that will do.

No, lol but I do have some friends :p it's for a helmet that im making that is almost done but could use some cooler mods. I was thinking of a guitar tuner ? If I could hit the right pitch and re-wire it to an electric airsoft gun :)
