Did you watch the video on Cued Speech? It's not a set of signs for common phrases at all. It's simply a small set of gestures that accompany some of the hard-to-lip-read sounds, like /m/ /p/ /b/.

So if you're saying "mat" "bat" or "pat" those all look the same to a lip-reader. With the cues, you have a small gesture that is distinct for /m/ /p/ /b/.

They combine together to make a total of about a dozen gestures that can be used to differentiate between any hard-to-understand English word.

So it's not a phrase book. It just allows you to say anything you want to say and be understood a little more clearly by a lip-reader.
