Ae is able to do automated audio animations. And YES without plugins.

Firts. You must understand about Lip Sync. Our friend Aharon Rabinowitz did an excelent job explaining this in this post.

Once you know how to lip Sync yo are ready to work with automated lip syncing.

You must convert your audio file to Keyframes. to do this. select your audio layer in the AE timeline, then go to Animation Menu > Keyframe Assistant > Convert Audio to Keyframes.

You´ll get a new layer in your timelime, this is a keyframe representation of your audio file. It has 3 layers, you can delete 2 of them (if you want to) and work with only one layer

Click on the “Slider” option of the keyframe layer to select it and them in the Graphic Editor (over the timeline) to see what you got.

Remember you must have done a time-remap of your animation the way Aharon shown above.

Now you can start asigning values to your Animation. You can “link” your keyframe layer to the Lips layer and watch if it works

Parhaps you must perform some adjustements, but this is it

Not so hard…

Best reggards…
