[Voice Operation Example of Voice Control Remote Control]

2 and FIG. 4, FIG. 4 is a schematic diagram of voice operation of the voice-activated remote controller provided by the present embodiment. The voice operation of the voice-activated remote controller 1 of the present embodiment can be performed in conjunction with the architecture of FIG. 2 and FIG. 3 for convenience of description, but can also be through other hardware architectures, and the present invention is not limited thereto.

In step S401, an input sound signal is received. In this step, the voice-controlled remote controller 1 receives the voice input of the person's voice through the sound collection circuit 11, that is, the sound pickup circuit 11 can provide the input sound signal to the voice control circuit 12 for reception.

In step S403, it is determined whether the sound signal is identifiable. In this step, the sound The remote controller 1 controls whether the input sound signal and the preset sound signal are in compliance. When the comparison is matched, the input sound signal is recognized as identifiable, and when the comparison is not met, the input sound signal is determined to be unrecognizable. In an embodiment, the voice control circuit 12 in the voice-controlled remote controller 1 compares the input voice signal with a plurality of preset voice signals stored in the non-volatile memory 121 to determine whether the identifiable one is identifiable. Or an unrecognizable condition. When the determination in step S403 is NO, the process proceeds to step S401.

In step S405, when the determination in step S403 is YES, it is further determined whether or not the voice command is a digital. In this step, when the voice control remote controller 1 determines that the sound signal of the input sound is matched with one of the preset sound signals, it is further determined whether the voice command corresponding to the matched preset sound signal is a number.

In step S407, when the determination in step S405 is NO, the corresponding remote command is output. In this step, the control circuit 10 in the voice-controlled remote controller 1 receives the voice-activated circuit 12 to output a voice command that does not belong to the number, and then the control circuit 10 outputs a remote command corresponding to the voice command to the wireless transmission circuit 14 according to the remote control code table.

In this step, when the control circuit 10 in the voice-controlled remote controller 1 receives the voice-activated command outputted by the voice-control circuit 12, it controls the timer circuit 17 to start timing operation for a predetermined time period.

In step S411, the voice command of the preset time zone is combined. The voice control remote controller 1 sequentially receives the voice control commands belonging to the one-digit number or the multi-digit number in this preset time zone in this step. In one embodiment, the timing circuit 17 is subdivided into N unit time periods (e.g., 1 second) in a predetermined time period, and only receives a single number of voice commands per unit time. In this way, when the non-volatile memory 121 stores only 10 sets of preset sound signals of numbers 0 to 9 for numbers, the voice command of each representative number in a plurality of unit time can be received in sequence, and then grouped. A voice command that can represent a combination of N digits is synthesized. Therefore, through this input digital processing mode, although the non-volatile memory 121 stores only 10 sets of preset sound signals of numbers 0 to 9 for numbers, the voice-controlled remote controller 1 can input voice commands of a plurality of digital combinations.

In step S413, a corresponding remote command is output. In this step S413, the voice control remote controller 1 combines the foregoing step S411 to obtain a voice command representing one or more digits, and outputs a relative remote command to the electrical product 3 according to the remote controller code table.

For example, when the electrical product is a television set, the execution of step S407 can be used, for example, to remotely control the volume of the television or the switching of the TV channel. If the execution of step S413 is performed, the switching of the television channel can be directly designated by the voice input. For example, when the above N is 3, the representative person can directly input the channel selection of any channel of 0 to 999 channels by voice.
