If I understand you correctly you want to capture voice packets. When I was training someone on this - here are the steps I used.
          1.  I picked an IP phone to trace . Example I have extension 2224 on my desk.
          2. I found out what port that was going to on our switch
          3. You have 2 choices
                    A. You can mirror the port and hook ethereal to the mirrored port.
                   B . disconnected the port and put a hub in between and hook your analyzer up.
         4. I first wanted to show steps phone would go to to boot.
              I started Ethereal and unplugged phone and caught a sniff of what was happening.
         5. I started another trace and made a phone call. Captured that call
        6. Went to statistics and looked for jitter or other impairments
     To listen to actual voice traffic I don't believe ethereal does that. I could be wrong -it wouldn't be the first time nor would it be the last. 
 Is the reason for listening to listen for impairments?    
    What is the plan you have?

I am a university student and I have a project on network analysis. I don't know how and where to start the project from.
my project is concept of network analysis and the only, I want to capture data voice packets which goes through network.
besides that I want to merge and edit them after that I will listen to them by making a program.
