Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] The invention provides a voice dual-mode fan control method, the purpose of which is to control the fan through voice; after waking up the fan through a wake-up word, the voice is used to control the fan again, and the false trigger rate is low. The present invention provides a smart fan combined with voice control and remote control. The fan can be woken up by a wake-up word. After the fan is woken up, the fan can be controlled by a voice command. At the same time, the fan can also be controlled by a remote control.

Abstract

The invention discloses a speech dual-mode fan control method. The method includes the following steps that: if a fan works in a wake-up word mode, first speech signals are received and converted intofirst identification signals, speech feature extraction is performed on the first identification signals, so that whether the first identification signals are wake-up words is judged, if the first identification signals are the wake-up words, the fan is switched to a command word mode; if the fan is operating in the command word mode, second speech signals are received and converted into second identification signals, speech feature extraction is performed on the second identification signals, so that whether the second identification signals are command words is judged, and if the second identification signals are the command words, the command type of the second identification signals is determined; and if the command words are not identified within preset recognition time, the fan is switched to the wake-up word mode. With the speech dual-mode fan control method of the invention adopted, a user can control the fan through speech or a remote controller without going to the fan; theuser wakes up the fan by the wake-up words, and then controls the fan through a speech command; and therefore, the false triggering rate of speech control commands can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of fan voice control, in particular to a voice dual-mode fan control method. Background technique [0002] One of the fan control methods in the prior art is to control the switch and speed of the electric fan through knobs and buttons. The disadvantage of this fan control method is that the user must walk in front of the electric fan to control the fan, which is inconvenient for the user. [0003] In addition, in the prior art, controlling the switch and speed of the electric fan through a remote controller is also a common control method for the fan. The disadvantage of this fan control method is that the user must use a remote controller to control the fan, and the remote controller needs to be frequently searched for, and the battery of the remote controller needs to be replaced. It is inconvenient and not environmentally friendly for users. Contents of the invention [0004] The technical problem t...
