How has Eliza's role in the household changed ? How do Higgins and Pickering feel about her now?

The conclusion of Act III finds Mrs. Higgins scolding the men, declaring that their project with Eliza, while clever, cannot work because no skill in pronunciation or fancy dresses can change the subject matter of what Eliza talks about. The content will trump the style; she will always give herself away. Like Mrs. Pearce, she also disapproves of the fact that Eliza lives in the house with the two men. Moreover, she complains that Pickering and Higgins are treating her like a "live doll."

The men protest that they take Eliza very seriously and are quite taken with her talents, including the fact that she has a wonderful ear and has taught herself to play the piano. Mrs. Higgins reminds them of the problem they have not yet faced--what to do with Eliza after the experiment is over--and the men reply that they will set her up in some sort of genteel occupation. They exit, talking about how they will take Eliza to a Shakespeare exhibition and then have her mimic all of the people there when they get home. Mrs. Higgins resumes writing letters and exclaims, "men!!" with exasperation.
