In this application, by using a method for collaborative recording by using a mobile terminal and the true wireless stereo earbud, recording with more complete data amount can be collected, and cooperative noise reduction is performed on a recording signal collected by the mobile terminal and a recording signal collected by the true wireless stereo earbud, so that accuracy and integrity of a human voice signal obtained through separation are higher. Further, in this application, when the true wireless stereo earbud performs recoding in a mode of single-earbud recording, a data amount of the true wireless stereo earbud is relatively small. Therefore, when the mobile terminal receives, through Bluetooth, data sent by the true wireless stereo earbud, excessive occupation of Bluetooth bandwidth of the mobile terminal is avoided, and power consumption of a mobile phone is reduced.

A speech wakeup method and device, and a readable storage medium are provided. The voice wakeup method includes: detecting voice signals that are input into at least two microphones and that meet a first condition; and determining, based on whether voice energy of the voice signals input into the at least two microphones meets a second condition, whether to wake up the electronic device; and if the second condition is met, waking up the electronic device; or if the second condition is not met, continuing to detect a voice signal input into the microphone. The electronic device can be woken up in a wakeup-keyword-free manner.
