A passive human detection method and apparatus, a device, and a medium are provided. The passive human detection method includes: acquiring an infrared radiation signal in an environment, and acquiring a temperature of a target object; emitting an electromagnetic wave into the environment, and acquiring a reflected echo signal; determining a position of the target object in the environment based on the echo signal; matching a threshold range based on the position of the target object; and comparing the temperature of the target object with the threshold range to determine detection information of a human in the environment. The passive human detection method combines electromagnetic wave detection and thermal imaging to detect whether there is a human in the current environment. The passive human detection method can effectively filter out interference signals, greatly improving the accuracy and sensitivity of human detection.

The present disclosure relates to methods and devices for calling a taxi. A method may include determining whether a user should call a taxi, based on at least one of schedule data or schedule data. The method may further include, when it is determined that the user should call a taxi, generating and outputting a taxi calling order. In the present disclosure, a terminal device can automatically generate and output a taxi calling order when it determines that the user should call a taxi. The method or terminal can thereby initiate a taxi calling service as early as possible, and thus avoid delaying the user's schedule. Moreover, a process may require no user initiation and little or no intervention from the user. Thus, the method or terminal can simplify user operation and save the user's time.

An audio processing method for use in a server, includes: receiving an audio file uploaded from a terminal that has downloaded a first accompaniment music file of a song from the server, the audio file being generated by the terminal by encoding collected audio information relating to singing a portion of the song and the first accompaniment music file; and marking an unmarked, audio mixing portion in the received audio file as a portion that has been sung, to generate a second accompaniment music file of the song.
