Yes. I get that in French/Spanish education it is typical to default to masculine, but I think women should be able to practice conjugating for themselves. As opposed to accidentally getting into the habit of only making masculine statements. :3 I imagine they will probably add the feminine one as well.
If it was asking you to type out what you heard, bear in mind that there is a difference in pronunciation between the two - différent /difeʁɑ̃/ v. différente /difeʁɑ̃t/. The final 't' is pronounced in the feminine, but not in the masculine.
Of course, if it was asking you to translate from the English "I am different", there is no way of telling the two apart, and you should report it.
Practise more ! :P A good way to develop your "ear" for French is to search up on YouTube for reviews or speeches (There's a few really good Tedx Talks in French) and either watch with captions and try to discern the words or just sit back and listen to the rhythm & pronunciation
Not sure on a PC. On a Mac I can long press the "e" and a list of choices of accents pops up. You can also install a French keyboard on either a Mac or a PC and switch keyboards. It's pretty easy to switch keyboards on the fly, on the Mac it's command + space bar. Not sure on a PC, but I'm sure you can google it.
There are many instances in French, Spanish and German where the speaker does not match the gender of the sentence being spoken. A female voice should speak with proper gender, as in "je suis differente". But if a woman says "je suis different" then I guess she truly is different.
