Abstract

The invention discloses a method and a device for speech recognition in smart equipment and a computer readable storage medium, and belongs to the technical field of smart home appliances. The methodcomprises the following steps: determining a current energy value of a current frame sound signal in an acquired sound signal; acquiring a current feature vector value of the current frame sound signal if the current energy value is greater than an adaptive energy threshold of the smart equipment; and determining the current frame sound signal to be a voice signal if the current feature vector value is greater than a set feature threshold. By the manner, not only is the efficiency of speech recognition improved, but also the accuracy of speech recognition is improved.

Description

technical field [0001] The invention relates to the technical field of smart home appliances, in particular to a method, device and computer-readable storage medium for voice recognition in smart devices. Background technique [0002] With the development of smart home appliance technology, home appliances such as air conditioners, refrigerators, washing machines, range hoods, and electric fans can be intelligently controlled. Moreover, these smart devices can acquire voice signals and implement corresponding voice control. [0003] The sound signals collected on the smart device are not necessarily voices, or in other words, the collected sound signals also include some noises or noises, for example: the sound of opening the door, the sound of cooking, and so on. These sounds will be collected by the smart device together with the voice, so it will be difficult for the smart device to recognize the voice controlling the smart device from the collected sound signal.
