12. The electronic device according to claim 11 , wherein the voice data is obtained from a voice inputting device of the electronic device when an airflow sensor of the electronic device detects airflow, the at least one processor further caused to: de-noise noise in the voice data.
11. An electronic device comprising: at least one processor; and a storage device configured to store one or more programs that, when executed by the at least one processor, cause the at least one processor to: establish a central control tree for the electronic device; obtain voice data; recognize the voice data to obtain recognized voice data; and control an operation to the electronic device according to the central control tree based upon the recognized voice data; wherein the central control tree is established by: establishing a single control tree for each of a plurality of applications of the electronic device, and obtaining a plurality of single control trees, wherein each node of each of the plurality of single control trees corresponds to a serial number, wherein root nodes of the plurality of single control trees correspond to a same serial number, and other nodes of the plurality of single control trees correspond to different serial numbers; and obtaining the central control tree by merging the plurality of single control trees based upon the serial number corresponding to each node of each of the plurality of single control trees, wherein nodes corresponding to the same serial number are merged to be one node, and the other nodes corresponding to different serial numbers are correspondingly added to the central control tree; wherein the at least one processor is further caused to: display the central control tree on a display screen of the electronic device in response to user's input; delete a single control tree corresponding to one of the plurality of applications from the central control tree in response to a first signal; and add a single control tree corresponding to a new application to the central control tree in response to a second signal.
