The chastity and silence that was emphasized as the female virtue in the Renaissance era is one of the patriarchy ideological strategies to suppress and control the women`s voice and sexuality. This paper aims to analyze the patriarchal strategy on women`s voice and sexuality in King Lear focusing on the dynamics between the speech power and the gender. In the context of the Renaissance gender ideology, it is defined the father/male as the subject of the meaning and the daughters/females as the object of the meaning, which is represented through the love test scene in King Lear. And King Lear focuses, since then, on the two motifs; one is the brutality and incestuous passions of two daughters, and the other is the father`s misogyny on his own daughters. Although these motifs appear to show how female powers are dangerous, Lear, in the end, realizes that the speech value is not within the signs but within the contents in it, which can make it true that fathers and daughters, men and women, people and birds can sing together.
