Singing by women is not specifically mentioned by the Qur'an. 

However, verses 31:6 and 23:3 are often interpreted to refer to a prohibition on music, or certain types of music, due to the use of the words lughw and lahw (vain or idle speech). 

In Surat al-Ahzab, there are also instructions to the Prophet's wives telling them to speak "plainly".

Hope that helps!
