I was just made known about SoundCloud and love it. Here is a series of yelp/purrs/clucks.

Please tell me what I need to do differently, or if I am good to go and just need to keep practicing.

I like your clucks and purrs better than your yelps.  On the yelps, try picking up your cadence a bit, aiming for about 3 notes per second, and shortening the length of the individual notes by about half.

Agree with speeding up the rhythm of the yelps. If you haven't already watched them already, check out these videos.

Does this sound a little better? I apologize for the extra noise in the clip. That is my daughter sitting next to me.

I would still shorten the length of the individual yelp.  It's hard to explain on a message board.  I once called like you until an expert turkey hunter took me aside and showed me what the cadence should be.  The next morning I called in a tom by myself.  Keep at it.

No.  It sounds very monotone like a seal.

Break each call into 2 notes YE-LP.

The videos that JBIRD22 posted were very good videos...  Also, play some recordings of real birds, or good callers, and compare them to the sounds you are making...  This is a method I find very useful to myself...  In my own head, I sound great, until I compare my calling to real birds or good sounding callers.

I should also mention that as far as mouth calls (or any other calls for that matter), I am still on a pretty steep learning curve myself...  I was a bit disappointed to hear recordings of myself calling recently.
