The disclosure provides a method for displaying words. In the method, a speech signal is received. A pitch contour and an energy contour of the speech signal are extracted. Speech recognition is performed on the speech signal to recognize a plurality of words corresponding to the speech signal and determine time alignment information of each of the plurality of words. At least one display parameter of each of the plurality of words is determined according to the pitch contour, the energy contour and the time alignment information of each of the plurality of words. Thus, the plurality of words is integrated into a sentence according to the at least one display parameter of each of the plurality of words. Then, the sentence is displayed on at least one display device.
