I have seen several, very petite, small women commanding very large dogs...so yes, the masculine voice is not it. It's all in your carriage and demeanor...don't ask, COMMAND, and don't accept anything but immediate compliance. Then fall back on the spray bottle...it really does work LOL!Nonsense, of course you can. Take a deep breath to gather your energy, stand/sit up straight (body language is important), lower your voice (don't increase the volume), look her in the eye and say "NO/Eh/Quit" or whatever is your "Stop that!" command. Say it strongly and deeply enough to get her attention and do not smile. I've taken my hand and firmly moved the offending head/teeth aside (YMMV). Then, offer the distracting toy and play with her a bit. Tim's right, you have to be utterly consistent, 24/7. The downside is that it's a pain. The upside is that she's engaging you, but it's the only way she knows --- at the moment...
