Embodiment Construction

[0069] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0070] At present, speech recognition technology is mainly in two ways: cloud semantic recognition and local entry recognition. Cloud semantic recognition must rely on the network to be used, and the usage scenarios are limited. Local entry recognition can only recognize pre-set voice control command entries, and cannot realize free semantic understanding. For this reason, the present invention proposes a wake-up word training method for home appliances, which can customize local wake-up words to meet individual needs, and does ...

Abstract

The invention discloses a method and device for training a wakeup word of a household appliance and a household appliance, wherein the method comprises: acquiring a voice data sample of a wakeup wordin a preset audio format; extracting the feature information of the voice data sample; normalizing the feature information and determining whether the normalized feature information satisfies a presetcondition; and if so, saving the voice data sample of the wakeup word in a user-defined wakeup word bank. The method and device for training the wakeup word of the household appliance and the household appliance according to the embodiment of the present invention acquire the voice data samples of the wakeup word in the preset audio format, extract the feature information of the voice data samples, normalize the feature information, determine whether the normalized feature information satisfies the preset condition, and save the voice data sample of the wakeup word in the user-defined wakeupword bank if so, thereby achieving a user-defined wakeup word and satisfying the individual demands of the user.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to a wake-up word training method and device for household appliances and the household appliances. Background technique [0002] With the continuous advancement of science and technology, the application fields of products developed by speech recognition technology are becoming more and more extensive, involving in-vehicle systems, robots, home services, banking services, medical services, industrial control and so on. At present, speech recognition technology is mainly divided into two categories, one is cloud semantic recognition, which transmits speech signals to the server through the network for semantic analysis and understanding, and then transmits the results through the network. Typical representatives: Apple's Siri (voice assistant), Amazon's echo speaker, Microsoft Xiaobing and so on. However, this method must have a network to be used, and the usag...
