Step 305: carry out voice training.
Step 306: store voice characteristic value.
Step 307: whether decision finishes voice training, if not, gets back in the step 305, continues to carry out voice training and store voice characteristic value step; If not, then promptly temporarily stop the program of voice training, get back in the step 302, be holding state.
Step 308: when step 304 judges whether to start the voice training switch, if judged result is that then execution in step 308, further judge whether to receive signal.
Step 309: carry out speech recognition comparison instruction.
Step 310: whether identification is specific user, if just execution command (being step 311) if not, then is a shut down procedure, gets back in the step 302, is holding state.
And the internal control flow process of reflector of the present invention is as shown in Figure 8, and its key step includes:
Step 401: beginning.
Step 402: standby.
Step 403: judge whether microphone starts, if not, then get back to step 402 and continue standby, start, then carry out next step 404 if detect microphone.
Step 404: voice signal, after transmission finishes, get back to standby in the step 402.
By above explanation as can be known, the present invention has following effect:
1, voice identification function: can be filtered user's identity, have only specific user could start this remote control;
2, voice training function: can train specific user's voice, make the reception main frame of remote control be familiar with these specific users;
3, limit the specific user's of multidigit function: by the function of voice training, the instruction that the reception main frame of remote control only is familiar with these specific users and is assigned is considered as illegal user to the user through voice training not.
Effect of the present invention can be given and being summarized as follows in a word:
1, do not need traditional remote control to send out transmitter;
2, controlled the action of remote control by voice;
3, tool limits the specific user's of multidigit function;
4, the high confidentiality of tool, security;
5, avoid losing the potential danger of traditional remote controller.
