14. The electronic device according to claim 10 , wherein the processor is configured to, after obtaining the Q pieces of first representation information, perform acts of: determining a second face image matched with the target character according to the Q pieces of first representation information; replacing the first face image in the M second video segments with the second face image to obtain M target video segments, wherein the M video segments correspond to the M target video segments one by one; and merging the N target speech segments with the M target video segments to obtain an outputted video.
