King, the 78-year-old widow of Martin Luther King Jr., has recovered to the point where doctors released her Thursday from Piedmont Hospital.
"Our prayers have been answered," daughter Bernice King told the Atlanta Journal-Constitution.
King was hospitalized Aug. 16 after suffering an early morning stroke and heart attack brought on by a heart condition.
At the time she was admitted, her physician, Dr. Maggie Mermin, said the right side of King's body was weak, one side of her face was immobilized and she was unable to speak.
Mermin said King's speech has improved to the point where she can have slight conversations and come up with spontaneous phrases.
"Her face looks normal. Her smile is there," Mermin said. "Her right hand is slower than her right leg. Her right leg is doing well."
