Voice wake-up method and system, electronic equipment and storage medium

The embodiment of the invention provides a voice wake-up method and system, electronic equipment and a storage medium. The method comprises the following steps: performing signal processing on user voice, and determining a first beam forming audio; performing real-time wake-up identification on the first beam forming audio by using a first wake-up engine, and if the first beam forming audio is identified to belong to a partial wake-up word, uploading the first beam forming audio and a second beam forming audio determined after the half-word wake-up mode to a second wake-up engine; and using the first wake-up engine to determine wake-up confidence coefficients of the first beam forming audio and the second beam forming audio, and if the wake-up confidence coefficients do not reach a preset wake-up threshold value, judging whether to trigger voice wake-up according to a received wake-up result fed back by the second wake-up engine. According to the embodiment of the invention, cross validation is carried out by
