Method and system for speech control based on Android system

Abstract

The invention discloses a method and system for speech control based on an Android system. The method comprises the steps that when a speech instruction is received, speech semantic text information is acquired after speech semantic recognition of the speech instruction, and semantic classification is carried out to the speech semantic text information; according to a semantic class to which the speech semantic text information belongs, a functional behavior characteristic value corresponding to the speech instruction is determined; and according to the functional behavior characteristic value, a corresponding activity is searched in a preset speech mapping table, and the activity is then called by the Android system. The method and system disclosed by the invention are characterized in that a speech recognition function is coupled with the Android system; and coupling of the function with each application is relieved. The Android system has a relatively stable state, and a core mechanism of the system is less likely to suffer from changes. Hence, when a speech assistant changes or an application which is required to respond to whole-course speech changes, the other side does not need to be changed or only does need to be modified slightly, so that maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of voice control, in particular to a voice control method and system based on an Android system. Background technique [0002] The whole process of voice interaction requires the voice assistant to know the application and interface that the current user is interacting with, and also needs to know the information displayed in the application interface, so that it can give priority to the functions on the current interface when doing voice recognition and semantic understanding, and realize voice calls. Such as figure 1 As shown, the working process of the existing full voice interaction method is as follows: [0003] a1. When the voice interaction is started, the language point is notified to the application in the form of a Broadcast message to inform the current application to start submitting scene information; [0004] b1. When the application is displayed in the foreground, submit the current scene in...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a voice control method and system based on the Android system in view of the deficiencies in the prior art, which solves the problem that all applications that want to respond to voice in the existing full-range voice interaction method need to communicate with the voice Assistant docking adaptation, increasing the coupling of the whole process of voice and various applications
