Is it permissible to listen to Qur'an recitation by adult women from behind a veil for the purpose of correcting the recitation?

It is preferable for a woman to teach the Quran to women in the mosque or at home, as this is safer and further removed from temptation. If this is not possible, and it is sufficient to memorize through a recorder or computer with the sisters collaborating in review and follow-up, then this is good. If there is a need for a man to teach them due to the absence of a female teacher and the impossibility of correcting recitation through a recorder or computer, then there is no harm, provided that the teaching is from behind a screen, that there is no softness in speech, that speech is only as much as needed, and that the teacher withdraws if he feels his heart inclining or takes pleasure in the voice of one of them. The teacher should also be elderly, married, and known for righteousness.
