Based on the above hardware structure, an embodiment of the instruction obtaining method of the present invention is provided.

Referring to fig. 2, fig. 2 is a flowchart illustrating a second embodiment of a method for obtaining an instruction according to the present invention, which is used for a sending end, and the method includes the following steps:

step S11: and receiving a voice instruction.

It should be noted that the execution main body of the present invention is a sending end, and the sending end may be any one of the sending ends described above, which is not described herein again. The voice command is usually sent by the user through a voice input module of the sending end, and may also be sent by the user through other electronic equipment connected to the sending end.

Further, before step S11, the method further includes: receiving a wake-up instruction when audio information is played; based on the wake-up instruction, pausing the audio information; accordingly, step S11 includes: and receiving a voice instruction when the audio information is in a pause state.

It should be noted that, users usually use the sending end to play audio information (or video information) to meet the entertainment requirement; meanwhile, the main body of the method (the sending end of the instruction obtaining program) of this embodiment is not always in a state of receiving the voice instruction, and usually requires the user to send a wake-up instruction to wake up the instruction obtaining program of this embodiment; the wake-up instruction may be a voice instruction, a key instruction, a gesture instruction, or the like, which is not limited in the present invention.

When a wake-up instruction is received and the sending end outputs audio information (or video information), the sending end pauses playing the audio information (or the video information) to receive a voice instruction; meanwhile, when the voice instruction reception is finished, the audio information (or video information) can be continuously played.

In addition, when receiving the wake-up instruction, the sending end directly receives the voice instruction.

Step S12: and cutting the voice command to obtain a plurality of sub voice commands.

The voice instruction is usually longer voice information, the amount of data information is larger, the transmission speed of the voice instruction transmitted to the cloud end on the network is lower, and meanwhile, the cloud end consumes more resources and time when the voice instruction is converted; it can be understood that, in the same network environment, compared with the voice instruction, the selected voice instruction (one sub-voice instruction of a plurality of sub-voice instructions obtained after the voice instruction is cut) has less data volume and high transmission speed, and meanwhile, when the cloud end is at the same processor utilization rate, the cloud end has higher data processing speed on part of the voice instruction and has lower data processing speed on the whole voice instruction; when the cloud end processes the same voice command, the processing speed is higher when the utilization rate of the cloud end processor is lower, and the processing speed is lower when the utilization rate of the cloud end processor is higher.

Because the utilization rates of the cloud processors are different, the conditions of the voice commands sent to the cloud by the sending end are also different (the utilization rate of the cloud processors is high, the selected voice commands are sent, the utilization rate of the cloud processors is low, and the sub voice commands are sent). No matter how the utilization rate of the cloud processor is, the sending end cuts the voice instruction into a plurality of sub voice instructions in advance, namely, cuts the voice instruction in advance. And then the sending end selects to send a selected voice instruction according to the utilization rate of the cloud processor when the utilization rate of the cloud processor is greater than a preset threshold value, or directly sends the voice instructions to the cloud end without determining the selected voice instruction when the utilization rate of the processor is not greater than the preset threshold value.

The cloud end can be an internet of things cloud end or a server and the like, the cloud end is in communication connection with the sending end respectively, and the cloud end is used as an intermediate medium of the sending end and the receiving end (the cloud end comprises data information transmission and data information processing functions); the transmitting end is usually a smart phone, a tablet computer, a personal computer or the like, the receiving end is usually a smart home device, such as a smart refrigerator, a smart air conditioner, a smart television or the like, and the main structure of the smart home device refers to the structure of the transmitting end, which is not described herein again. The receiving end is an execution end for receiving the text instruction, and may be an intelligent home device, such as an intelligent television, an intelligent air conditioner, or an intelligent refrigerator.

Generally, before a sending end and a receiving end are connected to a cloud end, the sending end and the receiving end need to register at the cloud end, and the cloud end stores device information and the like registered at the sending end and the cloud end, and generally, when instructions or data information are transmitted between the sending end and the receiving end through the cloud end, the instructions or the data information may include device information (the device information of the sending end and the device information of the receiving end) or device states (the operating state of the sending end and the operating state of the receiving end) and the like.

In addition, the usage rate of the cloud processor generally refers to the usage rate of the processor at the current time, that is, the usage rate of the real-time cloud processor obtained from the cloud when the sending end executes the method of this embodiment, and generally, the usage rate of the cloud processor is presented in percentage.

Further, step S12 includes: obtaining a sound waveform of the voice instruction based on the voice instruction; based on the sound waveform and the voice instruction, a plurality of sub voice instructions are obtained.

Specifically, based on the voice command, obtaining a sound waveform of the voice command; determining a region with amplitude smaller than a preset amplitude value in the sound waveform as a silent region; screening a selected silent area with the duration longer than a preset duration in the silent area; determining an area in the voice instruction corresponding to the selected silence area as a cutting area; determining a cutting point in the cutting area; and cutting the voice command by using the cutting point to obtain a plurality of sub voice commands.

The expression form of the sound waveform may be a waveform diagram or may be in another form. Generally, the voice command does not contain full user voice, there may be a vacuum segment (the interval in which the user speaks, and there is usually no voice in the interval, which is an invalid interval, and the vacuum segment corresponds to a silence region in the voice waveform), and generally, the voice command after the longer vacuum segment includes important command information.

The vacuum section has no sound of a user, so that the amplitude of the sound waveform corresponding to the vacuum section is small (even if some noise is included, the amplitude does not change greatly), and is smaller than a preset amplitude (the preset amplitude can be set by the user according to needs, it can be understood that the same voice command, the amplitudes of the sound waveforms obtained by different algorithms are different, the corresponding preset amplitudes are also different, and the determination needs to be performed according to actual conditions), and then the region in the sound waveform corresponding to the vacuum section is determined as a silence region.

In addition, there is always a very short interval (corresponding to a silence region with a short duration in the sound waveform) between each character in the user's speech information, and this short interval is not the pause of the user, and it is necessary to remove this short interval, that is, the silence region smaller than or equal to the preset duration is not the object of selection, in other words, the silence region larger than the preset duration is the selected silence region. The preset time length can be set by a user according to needs, the invention is not limited, and generally, the preset time length does not exceed 1 s.

Any point in the selected silence area can be used as a cut point, which can be a starting point (time starting point) of the selected silence area, or an ending point (time ending point) of the selected silence area, for example, the voice command 12s, and the selected silence area is the 5.50 th s-7.00 th s therein, so that the cut point can be the 5.50 th s, or the 7.00 th s, or any one of the 5.50 th s-7.00 th s. Wherein, in order to increase the accuracy, the second is taken as the unit, and the last two digits accurate to decimal point are the best.

Step S13: and acquiring the utilization rate of the cloud processor.

Step S14: and when the utilization rate of the cloud processor is greater than a preset threshold value, determining a selected voice instruction in the sub-voice instructions.

It should be noted that the preset threshold may be a percentage threshold of the utilization rate of the cloud processor, and may be set by a user, and the preset threshold is preferably 60% without limitation. Generally, the utilization rate of the cloud processor is greater than a preset threshold value, the load of the cloud processor is high, and the processing speed is low; meanwhile, the selected voice command comprises less data information, and the transmission speed of the selected voice command to the cloud is high. At this time, the transmitting end only needs to transmit the selected voice command. The transmission time of the voice command and the conversion time of the voice command are reduced.

It should be noted that after obtaining a plurality of sub voice commands, because of different utilization rates of the cloud processor, the voice command sent to the cloud may be one voice command (i.e., a selected voice command) or all sub voice commands, and generally, when sending all sub voice commands, the selected voice command does not need to be determined, and only when sending one sub voice command, the selected voice command needs to be determined.

Further, step S14: when the utilization rate of the cloud processor is greater than a preset threshold value, screening a result silent area with the maximum duration from the selected silent area; determining a first sub-voice instruction after the resulting silence area as the selected voice instruction.

Generally speaking, when a user sends voice information, after a long pause, a voice instruction sent by a sending end includes an important voice instruction, and then a part of the voice instruction after the long pause is selected, that is, a first sub-voice instruction after a result silence area with the largest silence duration is selected as a selected voice instruction in the selected silence area, and the selected voice instruction is a part of instruction sent to the cloud end and serves as a basis for a receiving end to execute the instruction.

Step S15: and sending the selected voice instruction to the cloud end so that the cloud end obtains a first text instruction based on the selected voice instruction.

It should be noted that the selected voice command is in a voice format, the selected voice command cannot be executed by the receiving end, and the cloud end is required to convert the selected voice command into a text command executable by the receiving end.

It can be understood that the cloud processor is larger than the preset threshold value, and only needs to send the selected voice instruction, so that the transmission time of the voice instruction and the conversion time of the cloud to the voice instruction are reduced, and the instruction acquisition speed and efficiency are improved.

Further, the method further comprises: when the utilization rate of the cloud processor is smaller than or equal to the preset threshold value, the sub voice instructions are sent to the cloud end, so that the cloud end obtains a second text instruction based on the sub voice instructions.

And when the utilization rate of the cloud processor is less than or equal to a preset threshold value, all the sub-voice instructions are sent to the cloud end, so that the cloud end obtains a second text instruction based on the plurality of sub-voice instructions.

Further, the plurality of sub-voice commands have a preset sequence; the step of sending the sub-voice commands to the cloud comprises: and sending the sub voice instructions to the cloud according to the preset sequence.

The preset sequence of the sub-voices is the sequence of the sub-voices in the original voice command, and when the sub-voice commands are sent, the sub-voices are also sent according to the sequence. For example, a 10s long voice command is divided into three sub-voice commands of 0.00s-3.00s, 3.00s-6.00s and 6.00s-10.00s, and their sequence is the first sub-voice command of 0.00s-3.00s, the second sub-voice command of 3.00s-6.00s and the third sub-voice command of 6.00s-10.00s, respectively, and the sequence is the preset sequence and also the sending sequence.
