sound editing/enhancement task

i have female studio recordings, which i need to convert to sound like a male. i did a first attempt using Audition - but i sounds not live enough. i'm attaching both versions (source + what i did. source in 48KHz, mine in 16khz) i want either (or both) of these 1)a version that sounds similar to mine (similar pitch) but more lively, "open" 2)a different - better, best, version of the conversion to male voice (1) is more constrained - (2) is letting you do your best. workflow is as follows: worker will send some examples on the 4 segments, for items (1) and/or (2). once confirmed - we will do a batch (no manual tuning) of more files, and if still ok -will run ~1500 segments
