Using PHASE VOCODER in MATLAB

Hello ppl..
i m a new bie..
i m a student of electronics engg.
i have a project of "developling a voice converter in matlab which converts male voice to female voice in Real time & then implement it on DSP Kit.
i m using the demo in Matlab 7 & above with the call command of "dsppitchtime"
it is a PHASE VOCODER
i need to ask some basic conceptual questions.
1- How by changing or altering Phase we r changing the Pitch i mean what is the relation of Phase with Pitch??
2- In Phase Vocoder what do we mean by "Phase Calculation" and "Over-lap add"..i mean what is the theory behind it??
3- What is the theory behind "Analysis hop size" and "Synthesis Hop Size"??
