That realizes that the utility model provides can voice-operated intelligent refrigerator, has following advantage: after speech-sound intelligent is controlled at and uses on the refrigerator, make the user only need open one's mouth need not start with regard to controlled ice making case realize opening the door, close the door, freezer temperature is set, temperature of refrigerating chamber is set and understand the current running status of refrigerator, makes the intelligent refrigerator that can listen the people to command become possibility.

Below in conjunction with accompanying drawing, can be described further by voice-operated intelligent refrigerator of the present utility model.In the accompanying drawing:

Fig. 1 represents for the schematic diagram that the utility model can voice-operated intelligent refrigerator;

Fig. 2 for the utility model can voice-operated intelligent refrigerator structured flowchart;

Fig. 3 for the utility model can voice-operated intelligent refrigerator logic diagram;

Fig. 4 for the utility model can voice-operated intelligent refrigerator in the circuit theory diagrams of main control part;

Fig. 5 for the utility model can voice-operated intelligent refrigerator in the circuit theory diagrams of phonological component.

The utility model is to add speech recognition and relevant device on the conventional refrigerator controller, and speech utterance partly is located on the refrigerator and covers.As shown in Figure 1, comprise the refrigerator classical control system, refrigerator classical control system 1 comprises master controller 11 andperformer 12, on refrigerator classical control system basis, speech-sound intelligent control system 2 is set, and speech-sound intelligent control system 2 comprises universalphonetic recognition device 21, logic control element 22, sound generating mechanism 23, microphone and loudspeaker.Logic control element 22 is connected with master controller 11, operate according to the Content of communciation of speech-sound intelligent control system by theperformer 12 that is connected with master controller 11, perhaps logic control element 22 directly is connected withperformer 12, finishes corresponding operation by performer 12.When calling phonetic order, by gathering vocal print after 21 pairs of phonetic order digitlizations of speech recognition equipment, contrast one by one, discern with the phonetic order vocal print that deposits in advance,, signal is passed toperformer 12 carry out corresponding work if when speech recognition equipment is confirmed the instruction accurate and effective.12 pairs of universal phonetic recognition devices are smudgy or do not gather in advance, store and the phonetic order of failing to discern, prompting error message (as by lighting the lamp of makeing mistakes) or ignore.

As shown in Figure 2, for the preparation process before the work of intelligent refrigerator of the present utility model, be that the user sends voice by microphone, after preamplifier compression amplification filtering, carry out spectrum analysis, send into and carry out logical process in the logic circuit, after 2-3 affirmation, deposit corresponding voice command demanded storage district in, realize the vocal print collection.

For implementation procedure of the present utility model, it is the user's voice instruction, compare, discern with the phonetic order vocal print that has deposited in advance, when confirming the instruction accurate and effective, be about to signal and pass to the control format conversion portion, the control format conversion portion is converted into the receptible command format of master controller with treated voice command, gets in touch by communication form and master controller again.The speech utterance control section can be controlled sounding by speech control system, also can be by the main controller controls sounding.

In training process, " think " the phonetic order ambiguous when speech recognition equipment, express when inaccurate, can send cue (as lighting indicator lamp) or signal language, such as: " pardon ", up to correct typing voice command sample.In running, will provide cue or ignore delphic order.

The order of speech-sound intelligent controller and various voice suggestion: 1, the order that the effector sends
