Dog barking help!!

My dog has always had a barking problem since she was a puppy up until now at 7 years old. I love my dog, but I can’t take it anymore and I don’t know what to do. I’ve tried everything, training her to “speak” and “quiet”, vibrating collars, citronella spray, ultrasonic sound, and lastly even tried a shock collar as a last resort and still she barks anyways. She’s a very sweet and loving dog and doesn’t have aggression problems. I try to remove the thing she barks at so the barking doesn’t happen but sometimes she barks at nothing and just for attention. I need some serious help or I may be getting kicked out because of her barking. Anyone have any advice on what I could do to help?
