Hi CC :)
I've never had a problem getting my two to bark at strangers at the door or noises outside, but then that is probably because I'm fairly antisocial and like to hermitise myself away from the world as much as possible and they've become like their grumpy mistress :P
But, I have taught them to bark on command as well. :rolleyes:
I always use treats. I get them sitting and making eye contact, have the treat in my hand but just out of reach and then use the word "speak" or whatever word is appropriate. They picked it up quite quickly with several practices. I keep using the word and treating . Now they bark when they hear the word and occasionally get a treat for it.
Don't know if this will help and there will probably be others who have better ideas ;) A lot I would imagine depends on the dog/breed and what will entice her to do it. :)
