“Read the room” is a common phrase when talking about analyzing an audience while you’re the speaker. In case you’re unfamiliar with the phrase, you take into account nonverbal and verbal cues from the people you’re around and adjust your words accordingly. A good example of this would be that if you’re at a posh dinner party, avoiding sharing intimate details about your life (unless, of course, that’s the topic- and that’s where you’d “read the room” to adjust your words).
