Description

Remote control equipment and voice wake-up method Technical Field The application relates to the field of intelligent household appliances, in particular to remote control equipment and a voice awakening method. Background The voice wake-up scheme adopted by the intelligent remote control equipment at the present stage is a secondary standby scheme, the scheme collects audio through a digital signal Processing technology (DIGITAL SIGNAL Processing, DSP) chip, and then wakes up a main chip when wake-up words are included in the collected audio, and the remote control equipment correspondingly recovers from the secondary standby to a normal use state. When the remote control device is in a normal use state, the main chip and the DSP chip work simultaneously, and the power consumption is high. Disclosure of Invention In order to solve the technical problems, the application provides a remote control device and a voice wake-up method, which are used for solving the problem that the voice wake-up scheme adopted by the intelligent remote control device in the prior art has higher power consumption.
