How do you practice the marked phrases in a youtube video?

I don’t know how to do practice marked phrases in a youtube video. For example, if I watch a video I can see all the phrases I marked next to the video. I can even play each phrase to hear it. But when I choose “practice” under the saved section it sends me to phrase pump which starts going through the standard list of phrases. How do I practice the actual phrases I’ve saved? And when practicing is there a way to also hear the actual audio, like you can on the list of phrases that is show in YouTube), instead of a computer generated voice? The voice is good overall but obviously not the same as human speech.
