  "textContent": "The present application discloses a noise reduction method and apparatus for an on-board environment, an electronic device and a storage medium, which are applicable to a field of computer technology, and particularly to a field of audio processing. An aspect of the present invention discloses: receiving (S110) an interference signal in the on-board environment and receiving a sound signal in the on-board environment, the interference signal comprising a vibration signal of a vehicle; and performing (S120) noise reduction processing on the sound signal in the on-board environment to obtain a noise-reduced signal; wherein, the noise reduction processing comprises cancelling the interference signal from the sound signal in the on-board environment. According to embodiments of the present application, the vibration signal of the vehicle may be canceled from the sound signal in the on-board environment, so as to improve the noise reduction capability of the acoustic echo cancellation in a speech recognition system and increase the signal to noise ratio of effective signals, thereby effectively improving the speech recognition and wake-up capability of the system.",
