Is it permissible for a woman to raise her voice when saying the takbir and reciting [Qur’an] in her prayer, whether alone or with her husband?

A woman is permitted to recite aloud (jahr) and say the takbir aloud in her prayer when she is alone, or in the presence of her husband or her mahrams. However, her voice should be lower than that of men. She should recite silently (sirr) if there are non-mahram men present.
