Why it's done

Trans women who seek voice feminizing therapy want to adapt their voices and communicate in a way that matches their gender identity. This can help lessen the feeling of discomfort or distress that might accompany a difference between gender identity, sex assigned at birth or sex-related physical characteristics (gender dysphoria). Having a voice that doesn't match your gender identity can also cause safety issues, such as harassment, in certain circumstances.

While voice deepening sought by transgender men can typically be achieved by masculinizing hormone therapy, feminizing hormone therapy doesn't have the same impact on transgender women's voices. Anti-androgens and estrogens have no effect on the voice.

Voice feminizing therapy isn't right for all transgender women. You might prefer a non-normative voice to signal your distinct transgender identity. The decision is up to you.
