Zusammenfassung:The invention discloses a wake-up model generation method, an intelligent terminal wake-up method and device. The invention discloses a wake-up model generation method, belongs to the technical fieldof voice wake-up, and the wake-up model generation method comprises the following steps: marking the start and stop time of each wake-up word contained in wake-up word audios in a sample audio set, and obtaining marked wake-up word audios, and the time length of the wake-up word audios is not fixed; adding noise to the marked wake-up word audio by using a negative sample audio containing background noise to obtain a positive sample audio; respectively extracting a plurality of audio frame features from the positive sample audio and the negative sample audio, and performing frame label labelingon the positive sample audio and the negative sample audio to obtain a plurality of audio training samples; and training the recurrent neural network by using the plurality of audio training samplesto generate a wake-up model
