Corinna's comments come a month after reports claimed Michael was responding to her voice.
The couple have been married for 14 years
Following news that the F1 ace had finally left Grenoble hospital following his life-threatening skiing accident in December, German newspaper Bild said that Michael is breathing unassisted for periods of time and is reacting to voices around him – particularly Corinna's.
"The voice of Corinna has a much stronger effect on him than the voices of other people," the paper wrote.
It also reported that Michael, 45, lost 44 lbs in weight while being treated for the severe brain injuries he suffered while skiing in the French Alps, although physiotherapists have been giving him regular exercise treatment to keep his muscles working.
Corinna says Michael's condition is "getting better"
In a statement, his manager Sabine Kehm confirmed that he had been removed from the artificially induced coma in which he has spent the last five months, and said he would now "continue his long phase of rehabilitation".
Michael is continuing his rehabilitation at the University Hospital of Lausanne (CHUV) in western Switzerland. The hospital is just 20 miles from the Schumacher family home, on the shore of Lake Geneva.
