Problems solved by technology

[0005] For this reason, the first object of the present invention is to propose a kind of speech recognition method, and this method can simultaneously solve the recognition problem of offline speech recognition system because the speech instruction issued by the user is not in the situation of preset speech instruction, and online speech Identify the problem that the system cannot return voice recognition results due to poor network signals, thus ensuring that the mobile terminal can quickly and accurately recognize the user's voice commands under any network status, and improving the user experience

Abstract

The present invention provides a voice recognition method and device. The voice recognition method comprises the following steps: a voice command is received by a mobile terminal, and the intensity of a first network signal of the mobile terminal is obtained; when the intensity of the first network signal is not less than a preset threshold, the voice command is sent by the mobile terminal to a cloud server, and the intensity of a second network signal of the mobile terminal is obtained; when the intensity of the second network signal is less than the preset threshold, the voice command is compared with the voice command prestored in the mobile terminal through the mobile terminal to determine whether the voice command is matched with the voice command prestored in the mobile terminal or not; and if the voice command is matched with the voice command prestored in the mobile terminal, a first voice recognition result may be outputted by the mobile terminal according to the prestored voice command. According to the voice recognition method in the embodiment of the invention, the user voice command may be quickly and accurately recognized by the mobile terminal at any network state.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice recognition method and a voice recognition device. Background technique [0002] With the rapid development of mobile terminal equipment, the application of voice recognition systems on mobile terminals is becoming more and more popular. For example, when the user is not allowed to use the mobile phone by hand (such as answering or making a call) while driving the vehicle, or when the user uses the car navigation and the input operation of the destination is complicated, the mobile phone is usually controlled by voice or Car navigation. [0003] Existing speech recognition systems include online speech recognition systems and offline speech recognition systems. Online speech recognition systems are used when there is a network, and offline speech recognition systems are used when there is no network. However, the current problem is that the network status will...
