In an embodiment, a method (100) is described. The method comprises obtaining (102) an indication of a speech pattern of a subject and using (104) the indication to determine a predicted time of inspiration by the subject. A machine learning model is used for predicting the relationship between the speech pattern and a breathing pattern of the subject. The machine learning model can then be used to determine the predicted time of inspiration by the subject. The method further comprises controlling (106) delivery of gas to the subject based on the predicted time of inspiration by the subject.
