Salam!
Sorry guys for butting in... so as long as you don't mind my behind, lol.

Anyways hun, habib, I feel that it is all about immersion. Whether that is by watching films that are traditionally 'male-oriented' or hanging out with other men, it does take time to be part of the 'culture'!
Some people are lucky to be able to immerse themselves easily in male/female culture. I myself was very lucky to also be part of female culture growing up, from childhood to teenage years, and onward. For some others, it does take a little learning and effort.
The hormones will affect your voice for you and make it lower. If you are not on hormones already, in the mean time just immerse yourself in the male speech of your culture. The more you do it, the more it will stick in your head, and you will end up talking like them!

Continue to talk to other men in your community, watch movies or films with male characters and listen to them, and the speech pattern will just come in time.
If you can not make male friends because of social problems - then Youtube, movies, tv, radio, etc. can help.
Be patient, honey! Transition takes lots of time, patience, effort, and faith in yourself.
