When you are animating the face, it is important to remember that everything is connected. So, if you just have the mouth moving by itself and the eyes and brows completely still, it is going to look extremely lifeless.
You need to connect the face, and a great way to do this is by squashing and stretching the face on certain words or when you change expressions.
It doesn't have to be very extreme and pushed, but if it exists in your animation, it will feel more organic and alive.
You don't need to do it for every word, but when you emphasize a word, it's a good time to animate it accordingly. If your voice sounds like it's emphasizing a word, make sure your animation matches; otherwise, it will look wrong.
