The invention relates to a user-defined command word training method and device and electronic equipment, and the method comprises the steps: obtaining an original decoding graph based on a first acoustic model and a first language model; collecting a preset number of audio data of the custom command word, and obtaining a confusion vocabulary of the custom command word based on the audio data and the original decoded graph; training the first language model through the custom command word and the confusion vocabulary to obtain a second language model; the first acoustic model and the second language model are subjected to composite operation, a target decoding graph is obtained, and the target decoding graph is used for recognizing the user-defined command word in the audio to be detected. Based on the method, configuration of the custom command word can be completed without participation of the custom command word audio in acoustic model training, resources are saved, and decoding efficiency is improved. 本申请
