Emilia having heard from Othello that Iago told him of Desdemona "cheating" on him with Cassio, accuses him of gross dishonesty leading to an unjust murder.

She then dies singing Desdemona's song and speaking of her purity and love for Othello, lying alongside her mistress.

[1] There is debate among critics as to Emilia's character nature in Othello, with some deeming her a villain and some as the true hero of the play.

This is because her allegiances initially seem to lie with her husband, and she displays the typical “wifely virtues of silence, obedience, and prudence"[2] of the Elizabethan period (as seen in her theft of the handkerchief in 3.1).

Yet later she seems more outspoken and appears to maintain a more progressive, even modern feminist view on Elizabethan attitudes towards marriage, as seen in her speech in 4.3.
