A method and apparatus for automatically generating dubbing characters, and an electronic device. The method for generating dubbing characters comprises: identifying audio information to acquire starting and ending time information about each identified audio basic semantic unit (S101); acquiring text information corresponding to the audio information, and identifying the text information, so as to acquire a text basic semantic unit (S103); recording the starting and ending time information about each of the audio basic semantic units in the corresponding text basic semantic unit (S105); and processing the text basic semantic unit into which the starting and ending time information is recorded, so as to generate dubbing characters corresponding to the audio information (S107). By means of the method, a dynamic lyrics file can be produced without using a manual method, thereby improving the production efficiency, reducing the production cost, and simplifying the production procedure.
