I had the same problem with my yorkie. She barked like crazy and wouldn't stop no matter how much i said "no", "stop" or "come" even though she does understand those general commands. What i did do however was catch her (even though it was insanely hard every time) and put her in cage for a time out for about 15 min. After a few weeks, she learnt her lesson and eventually stopped barking when we told her to.
Good luck!!!
