Voice therapy or voice training refers to any non-surgical technique used to improve or modify the human voice. Because voice is a "gender cue", trans people may frequently undertake voice therapy as a part of gender transition in order to make their voices sound more like that typical of their gender, and therefore increase their readability as that gender in society. Having voice and speech characteristics be in agreement with one's gender identity is often important to transgender individuals, whether their goal be feminization or masculinization.
