Everyone can use a different word to mimic one type of call.

Yelp- Wawp or Rock
Cluck- Puck or Buck
Cut- Cack,Cack,cack or Pick,Peck,Puck(over and over)
Cackle-Pop,pop,pop,pop
Kee-Kee- Pee,pee,pee
Putt- Put,put ,,put,put,put
Purr- rolling of the lips or throat purring like a cat
Gobble- Tucka,tucka (real fast)

Keep in mined that a Cluck,Cut and Cackle are all the sound of a cluck, but in a different speed and rythem.Some mouth calls will work on some calls better then others. For a starter I would suggest starting with a clear call and a Double Reed, something like the QuakerBoy' s Begginner double,Twin two or the Kee-Kee...BT
