Detailed Description
The foregoing and other features, aspects and utilities of the present general inventive concept will be apparent from the following detailed description of a preferred embodiment thereof, which is to be read in connection with the accompanying drawings. Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are simply directions with reference to the drawings. Accordingly, the directional terminology is used for purposes of illustration and is in no way limiting.
Fig. 1 is a schematic diagram of an intelligent speech system according to an embodiment of the invention. As shown in fig. 1, the intelligent voice system 100 includes a voice assistant 102a, a cloud service platform 104a, a projector 106a and a management server 108, all of which are connected to each other via a network (Internet) 110. A connection is defined as the mutual transmission of signals.
In the present embodiment, the projector 106a includes a micro control unit 106a1 and a light source device 106a 2. The voice assistant 102a is an external device connected to the projector 106a through a signal, for example, the voice assistant 102a has a microphone (microphone) and a Speaker (Speaker) and a wireless network medium and/or a wired network medium (for example, a network card or a related dongle, or not limited to Bluetooth (Bluetooth), wireless fidelity (Wi-Fi), Zigbee (Zigbee) or other wireless transmission media, or not limited to optical fiber or other wired transmission interface for transmission). Voice assistant 102a, such as a smart horn (e.g., Amazon)TMProduced Amazon Echo or GoogleTMGoogle voice assistant, but not limited thereto), or other intelligent devices that allow a user to input commands AS represented by voice signal AS1 and perform corresponding operations; alternatively, the voice assistant 102a may be a voice circuit device built in the projector 106a, and the voice circuit device includes, for example, a voice recognition processor, an AI processor (AI Processing Unit), or a Neural-network Processing Unit (Neural-network Processing chip). In various embodiments, before the user instructs the voice assistant 102a to perform the specific operation through the voice signal, the user may speak a specific wake-up word to the voice assistant 102a to wake up the voice assistant 102 a. The wake-up is the turning on or starting. For example, if the voice assistant 102a is Amazon Echo, the user may speak a wake up word such as "Alexa" and/or "Echo" to the voice assistant 102a to wake up the voice assistant 102 a. In addition, if the voice assistant 102a is a Google assistant, the user can speak a wake-up word such as "OK Google" and/or "Hey Google" to the voice assistant 102a to wake up the voice assistant 102a, but the invention is not limited thereto.
The cloud service platform 104a is connected to the voice assistant 102a through the network 110, and may be a network platform configured by a manufacturer of the voice assistant 102a to manage the voice assistant 102 a. For example, if the voice assistant 102a is Amazon Echo, the cloud Service platform 104a may be Amazon Web Service (AWS). For another example, if the voice assistant 102a is a Google assistant, the corresponding cloud service platform 104a may be a Google cloud server or a Google service platform.
In various embodiments, skill applications (still applications) corresponding to the voice assistant 102a may be stored/recorded on the cloud service platform 104a, and these skill applications may be installed on the cloud service platform 104a by manufacturers of the applications (e.g., projector manufacturers).
In one embodiment, the user can speak the voice signal AS1 to the voice assistant 102a, and the voice signal AS1 includes the calling name (invocation name) and the intention (intent) corresponding to the skill application to be used, and the order of the front and back arrangement is not limited. When the voice assistant 102a receives the voice signal including the call name and the intention, the voice assistant 102a can extract/obtain the keywords such as the call name and the intention from the voice signal, and transmit the keywords to the cloud service platform 104 a. Then, the cloud service platform 104a finds the corresponding skill application according to the call name, and accordingly controls the voice assistant 102a to perform the corresponding operation according to the user's speaking/inputting intention (for example, but not limited to, answering the user's question). For example, the user speaks a voice signal to start the projector of company a, which represents the calling name (invocation name) corresponding to the skill application to be used, and starts the representative intention (intent). When the voice assistant 102a receives the voice signal for turning on the projector of company a, the voice assistant 102a transmits the voice signal to the cloud service platform 104 a. Then, the cloud service platform 104a finds the skill application provided by company a according to the calling name, and the cloud service platform 104a provides the first reply signal R1 to the voice assistant 102a and controls the voice assistant 102a to answer the reply voice signal RS1 of "company a projector is being turned on".
The management server 108 is connected to the cloud service platform 104a and the projector 106a, and is configured to manage and control the projector 106 a. In one embodiment, the management server 108 may be configured and maintained by a manufacturer of the projector 106a, and may be configured to control the projector 106a accordingly according to the control command from the cloud service platform 104. In addition, the management server 108 and the cloud service platform 104a are not limited to be disposed on different servers in the present invention, and in other embodiments, the cloud service platform 104a and the management server 108 may be disposed on the same server, that is, the cloud service platform 104a may be disposed on the same server and connected to the management server 108.
In one embodiment, a specific skill application for controlling the projector 106a may be installed on the cloud service platform 104a, which enables a user to control the operating state of the projector 106a through the voice assistant 102 a. In this case, after the user speaks the call name and intention of the skill-specific application to the voice assistant 102a, the cloud service platform 104a can forward the intention of the user to the management server 108 managing the projector 106a based on the call name, so that the management server 108 adjusts the operation state of the projector 106a accordingly. The details of the related operations will be further described with reference to fig. 2.
Fig. 2 is a flowchart illustrating a method for controlling a projector according to an embodiment of the invention. The method shown in fig. 2 can be executed cooperatively by the intelligent speech system 100 shown in fig. 1, and details of the steps in fig. 2 will be described below in conjunction with the apparatus shown in fig. 1.
First, in step S210, when the voice assistant 102a receives the voice signal AS1 for controlling the projector 106a, the voice assistant 102a can extract/obtain a plurality of first keywords from the voice signal AS1, and transmit the first keywords to the cloud service platform 104 a.
In one embodiment, the first keyword may include a first alias (alias) AL1 corresponding to the projector 106a and a first control command CMD 1. In various embodiments, the user registers with the web page corresponding to the management server 108 of the projector manufacturer. That is, the projector 106a has been registered in advance on the management server 108 based on the first alias AL1 and unique identification information (e.g., serial number) of the projector 106 a. Also, the first alias AL1 of the projector 106a may be selected from a plurality of preset aliases (e.g., living room, bedroom, etc.) provided by the management server 108 during the registration process of the projector 106 a. In addition, the first control command CMD1 can correspond to the user's intention, i.e., the control operation to be performed on the projector 106a (e.g., turning on, turning off, increasing/decreasing brightness, increasing/decreasing contrast, turning on an On Screen Display (OSD), etc.).
In this embodiment, the cloud service platform 104a may include a first semantic analysis program and a plurality of second control commands CMD2, wherein each of the second control commands CMD2 is, for example, a control command pre-established by a manufacturer of the projector 106a (e.g., power on, power off, brightness increase/decrease, contrast increase/decrease, OSD on, etc.).
In one embodiment, the first voice analysis program may include a first check table, and the second control commands CMD2 may be recorded in the first check table for lookup, but the invention is not limited thereto. In another embodiment, the first speech analysis program may include information of the second control commands CMD 2. In another embodiment, the first check table recorded with the second control commands CMD2 can also be stored in a database (not shown) in the cloud service platform 104 a. In other embodiments, the second control commands CMD2 can also be generated by artificial intelligence (artificial intelligence) or machine learning (machine learning). For example, the cloud service platform 104a may perform deep learning based on the voice history inputted by the user, so as to learn the idioms and grammar of the user, and further establish a plurality of second control commands CMD2, but the invention is not limited thereto.
Therefore, the cloud service platform 104a may analyze the first control command CMD1 according to the first semantic analyzer, obtain/retrieve or generate the corresponding second control command CMD2 according to the first control command CMD1, and transmit the first alias AL1 and the corresponding second control command CMD2 of the projector 106a to the management server 108 in step S220. It should be noted that the cloud service platform 104a is configured to convert the first control command CMD1 originally being a voice signal into a text file for comparing with the second control command CMD2 in the cloud service platform 104 a. In one embodiment, the second control command CMD2 can be, but is not limited to, a text file.
For example, if the first control command CMD1 input by the user is "power on", the cloud service platform 104a can retrieve the second control command CMD2 corresponding to "power on" if the second control command CMD2 corresponding to "power on" is stored on the cloud service platform 104 a. Thereafter, the cloud service platform 104a may send the first alias AL1 of the projector 106a and a second control command CMD2 corresponding to "power on" to the management server 108. For another example, if the first control command CMD1 input by the user is "brightness up", the cloud service platform 104a can fetch the second control command CMD2 corresponding to "brightness up" if the second control command CMD2 corresponding to "brightness up" is stored on the cloud service platform 104 a. Cloud service platform 104a may then send first alias AL1 of projector 106a and second control command CMD2 corresponding to "turn up brightness" to management server 108.
In other embodiments, if the second control command CMD2 corresponding to the first control command CMD1 (e.g., turning on light) input by the user does not exist on the cloud service platform 104a, the cloud service platform 104a can control the voice assistant 102a to output/reply an unrecognizable response sentence (e.g., apology, i don't know your meaning), but the invention is not limited thereto.
Thereafter, in step S230, the management server 108 accesses/controls the projector 106a in response to the first alias AL1, and adjusts the projector 106a to the first operating state (e.g., power on, power off, brightness increase/decrease, contrast increase/decrease, OSD on, etc.) according to the corresponding second control command CMD 2.
In one embodiment, the management server 108 may generate a corresponding third control command CMD3 according to the second control command CMD2 and transmit the third control command CMD3 to the mcu 106a1 of the projector 106 a.
Accordingly, the mcu 106a1 of the projector 106a can receive the third control command CMD3 and adjust the first operating state of the projector 106 according to the third control command CMD 3. The micro control unit 106a1 includes, for example, a Central Processing Unit (CPU), or other Programmable general purpose or special purpose Microprocessor (Microprocessor), Digital Signal Processor (DSP), Programmable controller, Application Specific Integrated Circuit (ASIC), Programmable Logic Device (PLD), or other similar devices or combinations thereof. In one embodiment, the mcu 106a1 can include a first program (not shown), and the mcu 106a1 can obtain a fourth control command CMD4 according to the first program after receiving the third control command CMD3 to adjust the first operating state of the projector 106a accordingly. In this embodiment, the fourth control command CMD4 may include a digital signal, which is specifically used to adjust the hardware operating state of the projector 106a in response to the third control command CMD3 to embody the first operating state. For example, when the third control command CMD3 is "turn up brightness", the mcu 106a1 can execute the first program to generate a digital signal for turning up the driving current of the light source and/or increasing the rotation speed of the fan, and use the digital signal as the fourth control command CMD4, and the fourth control command CMD4 is provided to the light source apparatus 106a2 by the mcu 106a1, but the invention is not limited thereto.
In another embodiment, the first program of the projector 106a may include a second checking table, and the second checking table may include a pre-established fifth control command and a corresponding fourth control command CMD4, wherein the fifth control command is the same as the third control command CMD 3. That is, the first program of the projector 106a may record the corresponding relationship between each fifth control command and the fourth control command CMD4 in the second check table. In this case, when the mcu 106a1 receives the third control command CMD3, the fifth control command identical to the third control command CMD3 and the corresponding fourth control command CMD4 can be directly found from the second checking table, so as to adjust the hardware operating state of the projector 106a to show the first operating state. For example, the second check table may record a fifth control command CMD4 of "turn up brightness" and a fourth control command CMD4 of "generate a digital signal for turning up the driving current of the light source and/or increasing the rotation speed of the fan" corresponding to each other. Accordingly, when the third control command CMD3 is "turn up", the mcu 106a1 can search the second check table to find the fifth control command that is "turn up" together with the third control command CMD3, and then obtain the fourth control command CMD4 corresponding to the fifth control command (i.e., "generate a digital signal for turning up the driving current of the light source and/or increasing the rotation speed of the fan"). Then, the projector 106a can adjust the hardware operating status of the projector 106a according to the fourth control command CMD4 to embody the first operating status, but the invention is not limited thereto.
In addition, in one embodiment, the projector 106a may include electronic components such as a fan, a light source driver, a speaker, etc., and the third control command CMD3 may include information about and signals for controlling the electronic components. The information of the electronic device includes, for example, an identification code, and the signal for controlling the electronic device includes a voltage or a current. Accordingly, the projector 106a can specifically adjust the operation states of the related electronic components, such as increasing the rotation speed of a fan and/or increasing the voltage or current of a light source driver, in response to the third control command CMD3, but the invention is not limited thereto.
In view of the above, the method for controlling the projector according to the present invention enables the user to control the operating state of the projector 106a by speaking the voice signal AS1 to the voice assistant 102a, thereby providing a novel, intuitive and convenient control system for the projector.
In one embodiment, when the management server 108 accesses/controls the projector 106a, the projector 106a provides a second reply signal to the management server 108. That is, the projector 106a can accordingly feed back the operation status of the projector 106a and the current information of each component (e.g., the time of using the light source, the data of the relevant parameters of the projector set by the user) to the management server 108.
In one embodiment, after the projector 106a is adjusted to the first operating state, the projector 106a may report the first operating state back to the management server 108. Then, the management server 108 may forward the first operation status to the cloud service platform 104 a. Accordingly, the cloud service platform 104a generates a first response sentence according to the first operation state, and sends the first response sentence to the voice assistant 102a, so that the voice assistant 102a outputs the first response sentence. For example, if the projector 106a is turned on, the first response sentence output by the voice assistant 102a can be "the projector is turned on". For another example, if the projector 106a is adjusted to be in the power-off state, the first response sentence output by the voice assistant 102a may be "the projector is powered off", but the invention is not limited thereto.
In other embodiments, the method for controlling the projector according to the present invention can also allow the user to control the same projector through different voice assistants, which is described as follows.
Please refer to fig. 3, which is a schematic diagram of the intelligent speech system shown in fig. 1. As shown in fig. 3, the intelligent voice system 300 of the present embodiment includes voice assistants 102a and 102b, cloud service platforms 104a and 104b, a projector 106a and a management server 108.
In the embodiment, the voice assistants 102a and 102b may be manufactured by different manufacturers and managed by different cloud service platforms. For example, if voice assistant 102a is Amazon Echo, voice assistant 102b may be a Google assistant. Accordingly, the voice assistants 102a and 102b may be managed by the cloud service platforms 104a and 104b, respectively, wherein the cloud service platform 104a is, for example, an AWS, and the cloud service platform 104b may be a Google cloud server, but the invention is not limited thereto.
In this embodiment, the user can control the projector 106a by speaking the voice signal to the voice assistant 102a, and can also control the projector 106a by speaking the voice signal to the voice assistant 102 b.
In detail, when the voice assistant 102b receives the second voice signal AS2 for controlling the projector 106a, the voice assistant 102b can extract a plurality of second keywords from the second voice signal AS2, and transmit the second keywords to the cloud service platform 104b, wherein the second keywords include the first alias AL1 and the sixth control command CMD6 corresponding to the projector 106 a.
Similar to the cloud service platform 104a, the cloud service platform 104b includes a second semantic analysis program and a plurality of seventh control commands CMD7, wherein each of the seventh control commands CMD7 is, for example, a control command pre-established by the manufacturer of the projector 106a (e.g., power on, power off, brightness increase/decrease, contrast increase/decrease, OSD on, etc.).
In addition, in the embodiment, the cloud service platform 104b may analyze the sixth control command CMD6 according to the second semantic analysis program, obtain a corresponding seventh control command CMD7 according to the sixth control command CMD6, and transmit the first alias AL1 of the projector 106a and the seventh control command CMD7 corresponding to the sixth control command CMD6 to the management server 108. Thereafter, the management server 108 accesses the projector 106a in response to the first alias AL1, and adjusts the projector 106a to the second operating state according to the seventh control command CMD7 corresponding to the sixth control command CMD 6.
The details of the operations executed by the voice assistant 102b, the cloud service platform 104b, and the management server 108 cooperatively to control the projector 106a are substantially the same as the operations executed by the voice assistant 102a, the cloud service platform 104a, and the management server 108 cooperatively according to the previous teachings, and the roles of the second semantic analysis program, the sixth control command CMD6, and the seventh control command CMD7 are also similar to the roles of the first semantic analysis program, the first control command CMD1, and the second control command CMD2 according to the previous teachings, so the details thereof can refer to the description in the previous embodiments, and are not repeated herein.
In one embodiment, when the voice assistants 102a and 102b are located close to each other, it is possible that the voice signals AS1 or AS2 spoken by the user are received by both voice assistants 102a and 102 b.
In one embodiment, since the voice assistant 102a can receive different wake-up words than the voice assistant 102b can receive, the operations performed by the voice assistants 102a and 102b will also differ according to the wake-up words, i.e., only a single voice assistant can be woken up.
In various embodiments, the language family processed by the voice assistant 102a may be the same AS or different from the language family processed by the voice assistant 102b (i.e., the language family of the voice signal AS1 may be the same AS or different from the language family of the voice signal AS 2), and the operations performed by the voice assistants 102a and 102b will be different from each other according to the same or different language family.
For example, assuming that the language family (e.g., english) of the speech signal AS1 is different from the language family (e.g., japanese) of the speech signal AS2, the speech assistant 102a can output an unrecognizable response sentence when the speech assistant 102a receives the speech signal AS2 and the first speech analysis program cannot recognize the speech signal AS 2. Similarly, when the voice assistant 102b receives the voice signal AS1 and the second speech analysis program cannot recognize the voice signal AS1, the voice assistant 102b can also output an unrecognized response sentence.
Conversely, if the language family of the voice signal AS1 is the same AS the language family of the voice signal AS2 (e.g., japanese), the intelligent voice system 300 can perform other operations to control the projector 106a, and the details thereof will be described with reference to fig. 4.
Please refer to fig. 4, which is a schematic diagram of the intelligent speech system according to fig. 3. In this embodiment, when the voice assistant 102a also receives the voice signal AS2 for controlling the projector 106a, the voice assistant 102a can extract the second keyword from the voice signal AS2 and transmit the second keyword to the cloud service platform 104a, wherein the second keyword includes the first alias AL1 and the sixth control command CMD6 corresponding to the projector 106 a.
Thereafter, the cloud service platform 104a may analyze the sixth control command CMD6 according to the first semantic analyzer, and obtain an eighth control command CMD8 according to the sixth control command CMD6, wherein the eighth control command CMD8 is one of the second control commands CMD 2. Moreover, the cloud service platform 104a may transmit the first alias AL1 and the eighth control command CMD8 of the projector 106a to the management server 108. Thereafter, the management server 108 accesses the projector 106a in response to the first alias AL1, and adjusts the projector 106a to the second operating state again according to the eighth control command CMD8 corresponding to the sixth control command CMD 6.
In short, when the speech systems processed by the voice assistants 102a and 102b are the same and receive the same speech signal, the voice assistants 102a and 102b respectively implement repetitive control of the projector 106a through the corresponding cloud service platforms 104a and 104b, such as continuously performing two power-on operations or continuously increasing the brightness twice.

In this embodiment, the user can control the projector 106a by speaking the voice signal to the voice assistant 102a, and can also control the projector 106b by speaking the voice signal to the voice assistant 102 a.
In detail, when the voice assistant 102a receives the voice signal AS3 for controlling the projector 106b, the voice assistant 102a may extract a plurality of third keywords from the voice signal AS3, and transmit the third keywords to the cloud service platform 104a, wherein the third keywords include the second alias AL2 and the ninth control command CMD9 corresponding to the projector 106 b.
Then, the cloud service platform 104a may analyze the ninth control command CMD9 according to the first semantic analyzer to obtain a tenth control command CMD10, wherein the tenth control command CMD10 is one of the second control commands CMD 2.
Also, the cloud service platform 104a may transmit the second alias AL2 of the projector 106b and a tenth control command CMD10 corresponding to the ninth control command CMD9 to the management server 108. Thereafter, the management server 108 accesses the projector 106b in response to the second alias AL2, and adjusts the projector 106b to the third operating state according to the tenth control command CMD10 corresponding to the ninth control command CMD 9.
