Abstract: This application provides an application running method and an electronic device. The method includes: displaying, by an electronic device, a first interface, where the first interface is an interface displayed after a target application APP is started; prompting, by the electronic device in a case that the electronic device determines that a running duration of the target APP is greater than or equal to a duration threshold, a user to enter a voice token, where the voice token is randomly generated by the target APP; and making the target APP exit, and displaying, by the electronic device, a second interface in response to determining, by the electronic device, according to the voice token entered by the user, that the user is a target user, where the second interface is an interface displayed by the electronic device after the target APP has exited.

Abstract: An audio recognition method and an audio recognition apparatus, which can improve the accuracy of sound event detection. The method includes: acquiring a to-be-detected audio signal; determining that an acquisition scenario of the to-be-detected audio signal is a first scenario according to the to-be-detected audio signal; and determining, based on the to-be-detected audio signal and a sound event recognition model corresponding to the first scenario, a sound event identified by the to-be-detected audio signal, where the sound event recognition model corresponding to the first scenario is a neural network model trained with an audio signal in the first scenario and configured to identify a sound event in the first scenario based on the audio signal.
