                      I am facing voice jittering issues with 7921 phones especially when roaming around the AP's.

WLC Version :

7921 version : 1.3.3

      We are having a combination of 1131 AP for indoor and 1242 ap for outdoor. During roaming we are getting alarms in the controller saying that coverage hole detected even sufficient coverage is available. Do you face any similar issues. Is the issue is related to the firmware or something else. The jitter will happen for 2 or 3 seconds  after that it will come to the normal state. Please provide your valuable suggestions

From the description you have I would first make sure that you have adequate coverage everywhere you need it.  Make sure that the phone can see an AP at -67dBm or better at all times.  Using the site survey utility in the phone would help you verify this.
