Description

TECHNICAL FIELD

The present disclosure relates to the field of voice control, and in particular to an electronic device, a method, a system, a medium, and a program capable of voice control.

BACKGROUND ART

Presently, voice-controlled home facilities (for example, voice-controlled lights, background music volume, curtains, etc.) have become more and more popular through multiple Mic sensors installed all over the home. In terms of voice-controlled home facilities, how to distinguish which device is the target device for voice control is a key issue.

The traditional method is to tag each device, and the user controls the device by saying “device name+control command.” For example, “turn off the lights in the kitchen,” “decrease the volume of the speakers in the study room,” “close the curtains in bedroom 1,” etc. As the user needs to clearly remember the name of the device, when the user is old or the number of devices is large, it will cause confusion and lead to poor user experience.

Therefore, it is desirable to provide an improved voice control method compatible with existing voice control methods, so as to improve user experience.

FIG. 3 shows a flowchart of an exemplary method 300 for voice control according to an embodiment of the present disclosure. The method 300 may be executed by, for example, the electronic device 200 shown in FIG. 2, and according to a preferred embodiment of the present disclosure, the electronic device 200 may be a central controller or a server integrated in the network access device as shown in FIG. 1. The electronic device and the method used for the electronic device according to embodiments of the present disclosure will be described in detail below, with reference to FIG. 1 to FIG. 3.

As shown in FIG. 3, at step S301, the user's voice detected by the detector is received from at least one terminal device among a plurality of terminal devices equipped with detectors. The terminal device here may be, for example, the terminal device shown in FIG. 1, and each terminal device is equipped with a detector capable of detecting the user's voice, such as a sensor. The network access device and plurality of terminal devices in FIG. 1 form an intelligent IoT control system. For example, the network access device can be a set-top box or a router, and the plurality of terminal devices can be TVs, air conditioners, notebooks, iPads, mobile phones, desk lamps, stereos, curtains, etc. Each terminal device detects the user's voice in real time through the sensor, and sends it to the central controller in the set-top box or router thereafter.

At step S302, voice recognition processing is performed on the received user's voice to obtain the command contained in the user's voice. Voice recognition technology is a crossover technology that has achieved mature development, and the fields involved include signal processing, pattern recognition, probability theory and information theory, sound production mechanism and hearing mechanism, artificial intelligence, etc., which will not be elaborated herein.

According to a preferred embodiment of the present disclosure, performing voice recognition processing on the received user's voice includes creating a waveform file of the user's voice, filtering the waveform file by removing background noise and normalizing the volume, and breaking down the filtered waveform file into a plurality of individual phonemes. Here, phoneme is the basic building block of language and words, and is the smallest phonetic unit divided according to the natural attributes of speech. From the perspective of acoustic properties, phoneme is the smallest phonetic unit divided from the perspective of sound quality; from the perspective of physiological properties, a pronunciation action forms a phoneme. Different languages have different phonemes, and this is not elaborated herein. Performing voice recognition processing on the received user's voice further includes inferring words and entire sentences by sequentially analyzing the plurality of phonemes using statistical probability, thereby obtaining the command contained in the user's voice. For example, based on the first phoneme of a word, a combination of statistical probability (usually a hidden Markov model) and context is used to narrow the range of options and find the spoken word, and then the entire sentence is inferred by analyzing the order of a plurality of phonemes.

At step S303, the command is executed. According to an embodiment of the present disclosure, when the command contains a specific terminal device name and a control command, executing the command is to instruct the specific terminal device to execute the control command.

For example, after receiving a command to “close the curtains in the living room” from the iPhone held by the user, the curtains in the living room are instructed to close automatically. On the one hand, this makes it perfectly compatible with the traditional method of “device name+control command,” and on the other hand, this enables voice control to be performed remotely. For example, in an exemplary embodiment, in a large four-story house, the user is located in the bedroom on the fourth floor and is not sure whether the TV in the living room on the first floor is turned off. At this time, a voice command of “turn off the TV in the living room on the first floor” may be given. The detector installed on the device in the user's room, for example, desktop computer, curtains, etc., detects the user's voice of “turn off the TV in the living room on the first floor” and sends the detected user's voice of “turn off the TV in the living room on the first floor” to the central controller in the network access device (for example, router or set-top box), and then the central controller instructs the TV in the living room on the first floor to turn off by itself, so that the user does not have to specially run from the fourth floor to the first floor to confirm whether the TV is turned off or to specially go to the first floor to turn off the TV. Furthermore, in this case, the connection between the desktop computer or the curtains as the repeater and the central controller is wired, and the voice command is not attenuated in the process of transmission to the central controller.

According to another embodiment of the present disclosure, when the command only contains a control command and does not contain a specific terminal device name, executing the command includes analyzing the sound intensity of the control command, and in the case where the sound intensity of the control command is higher than a predetermined threshold, instructing the terminal device from which the control command with a sound intensity higher than the predetermined threshold is received, to execute the control command. It should be understood that the predetermined threshold may be set and/or adjusted according to actual conditions (for example, environment, etc.).

For example, according to an exemplary embodiment, when a user located in the living room gives a voice command of “decrease volume,” the terminal devices around the user (for example, a mobile phone that is playing video in the hands of another person in the living room; a TV that is playing in the living room; a notebook that is playing an online course in a room close to the living room, with the room door open) detect the voice, and each device sends the voice to the central controller. The central controller obtains the command “decrease volume” from the voices received from the mobile phone, TV, and notebook, respectively through voice recognition processing. Since the command only contains a control command without any specific device name, the central controller analyzes the sound intensity of the control command “decrease volume” received from the aforementioned mobile phone, TV, and notebook, respectively and compares the sound intensity of each voice with the volume threshold. For example, suppose that the volume threshold (in dB) is set to Thr, and the sound intensity of the control commands received from the mobile phone and TV is greater than Thr, while the sound intensity of the control command received from the notebook is less than Thr, then the central controller will instruct the aforementioned mobile phone and TV to lower the volume, while keeping the volume of the notebook unadjusted.

In another exemplary embodiment, based on the same principle, after setting an appropriate volume threshold Thr, a user watching a football game in the living room late at night can turn on the lights in the living room by giving a voice command of “turn on lights,” without disturbing the family members who sleep in the next room.

This is a fuzzy personalized control, which helps to distinguish the needs of family members in different rooms/areas, thereby improving user experience. For example, the aforementioned voice control of decrease volume/turn on lights not only meets the needs of the user who gave the command of decrease volume/turn on lights in his/her own environment, but also ensures that the users in the room are not affected by the command given, i.e., the notebook in the room continues playing the online course at the original volume/the lights in the room are not turned on, so as not to affect the user experience of users in the room.

Through the aforementioned electronic device capable of voice control, users can not only accurately control (including remote control) specific devices in the IoT system, but also control at least one device through a single simple command based on sound intensity detection, thereby improving user experience, especially when the device name is complicated or control or more than one device needs to be controlled at the same time.

The present disclosure may be implemented as any combination of devices, systems, integrated circuits, and computer programs on non-transitory computer-readable media, and can be applied to existing home IoT systems. One or more processors may be enabled as an Integrated Circuit (IC), an Application Specific Integrated Circuit (ASIC) or a Large-scale Integrated Circuit (LSI), a system LSI, a super LSI, or an ultra LSI component that performs part or all of the functions described in the present disclosure.

The present disclosure includes the use of software, applications, computer programs, or algorithms. Software, application programs, computer programs or algorithms can be stored on a non-transitory computer-readable medium, so that a computer with one or a plurality of processors can execute the aforementioned steps and the steps described in the attached drawings. For example, one or more memories store software or algorithm with executable instructions, and one or more processors can associate with a set of instructions for executing the software or algorithm so as to provide network configuration information management functions of network access devices according to the embodiments described in the present disclosure.

Software and computer programs (also called programs, software applications, applications, components, or codes) include machine instructions for programmable processors, and may be realized in high-level procedural languages, object-oriented programming languages, functional programming languages, logic programming languages, or assembly languages or machine languages. The term “computer-readable medium” refers to any computer program product, apparatus or device used to provide machine instructions or data to the programmable data processor, e.g., magnetic disks, optical disks, solid-state storage devices, memories, and programmable logic devices (PLDs), including computer-readable media that receive machine instructions as computer-readable signals.

For example, the computer-readable medium may include the dynamic random access memory (DRAM), random access memory (RAM), read only memory (ROM), electrically erasable read only memory (EEPROM), compact disk read only memory (CD-ROM) or other optical disk storage devices, magnetic disk storage devices or other magnetic storage devices, or any other medium that can be used to carry or store the required computer-readable program codes in the form of instructions or data structures and can be accessed by a general or special computer or a general or special processor. As used herein, magnetic disks or disks include Compact Discs (CDs), laser disks, optical disks, Digital Versatile Discs (DVDs), floppy disks, and Blu-ray disks, wherein magnetic disks usually copy data magnetically, and disks copy data optically via laser. Combinations of the above are also included in the scope of computer-readable media.

In addition, the above description provides examples without limiting the scope, applicability, or configuration set forth in the claims. Without departing from the spirit and scope of the present disclosure, changes may be made to the functions and layouts of the discussed components. Various embodiments may omit, substitute, or add various processes or components as appropriate. For example, features described with respect to some embodiments may be combined in other embodiments.
