If you haven't been able to find the Viseme track then that will be the problem.
To access the Viseme track just click the dropdown for your character on the Timeline as shown below. Then put a check in the tracks you want displayed such as the Viseme track.
You can then right click the Viseme track and select "Reduce Lip Keys" and "Lip Options" as shown in the video. And to access the Lip Editor just double click on the particular lip key you wish to edit from the Lips track.
