Description

Technical Field

[0001] The present invention belongs to the field of artificial intelligence voice technology, and in particular relates to a method and system for realizing voice broadcasting of an eye-protection smart speaker. Background Art

[0002] At present, myopia among teenagers has become a common concern at home and abroad. The core cause of myopia is long-term close-up use of the eyes. How to improve the speed of doing homework and shorten the time of doing homework is an urgent problem to be solved.

[0003] Huanggang Normal University has designed a multifunctional vision protection device, which uses a single-chip microcomputer as a controller, uses an ultrasonic module to measure distance, uses a photoresistor to detect light, uses a timer to realize the learning time timing function, designs a display circuit to display the distance, light intensity and learning time in real time, and uses a voice module to realize the voice reminder function. When the distance is less than the set value, and the light is greater than or less than the upper and lower limit set values, a voice reminder is issued; a button circuit is designed to realize the setting of distance, light and learning time; and information can also be transmitted to a mobile phone APP through Bluetooth communication, which is convenient for parents to supervise remotely.

[0004] Henan University of Technology uses a single-chip microcomputer as the main control chip and uses the ultrasonic distance measurement principle to measure the distance between the user's chin and the desktop. When the distance is less than the set value, the sound and light alarm is activated. The light intensity information is collected through a photoresistor, and the light is distinguished according to the level. The buzzer and LED lights are set to sound and light alarm when the light is insufficient. The timer is used to count, and the alarm starts when the system runs for 45 minutes to remind the wearer of the vision protector to take a rest. The LCD display module is used to intuitively display the distance, light intensity and learning time, which is convenient for the wearer to use. Summary of the invention

[0005] The purpose of the present invention is to provide a method for implementing an eye protection smart speaker voice broadcast system to solve the problem of low learning efficiency when writing following the smart speaker voice broadcast, thereby shortening the homework time and achieving the eye protection goal. The method comprises the following steps:

[0006] Step 101, the user configures the smart speaker to eye protection mode through the eye protection board;

[0007] Step 102, the user configures the speed of the smart speaker to slow through the eye protection board;

[0008] Step 103, the user configures the eye protection pause timeout duration of the smart speaker through voice interaction;

[0009] Step 104, the user issues a voice command to ask the smart speaker a question that needs to be written;

[0010] Step 105, the smart speaker analyzes the user's voice command through the voice cloud platform and generates a response content;

[0011] Step 106, the voice cloud platform transmits the response content to the voice playback module through the platform communication and adaptation module of the smart speaker;

[0012] Step 107, the voice playing module drives the eye protection adjustment module through the mode control module;

[0013] Step 108, the eye protection adjustment module processes the voice stream in segments;

[0014] Step 109, the eye protection adjustment module drives the speaker to play sound and the display screen to display text through the output drive module. Before all voice streams are played, the eye protection adjustment module responds to the replay instruction at any time;

[0015] Step 110: After all voice streams are played, the smart speaker automatically returns to the waiting wake-up mode.

[0016] Furthermore, the default timeout period for the smart speaker eye protection pause is 5 seconds, and the configurable range is 1 to 10 seconds. The steps for the user to configure the eye protection pause timeout period of the smart speaker through voice interaction are as follows:

[0017] Step 201: The user wakes up the smart speaker;

[0018] Step 202: The user issues a voice command to set the eye protection pause timeout period;

[0019] Step 203: The user voice command for setting the eye protection pause timeout period is transmitted by the smart speaker to the voice cloud platform;

[0020] Step 204, the voice cloud platform parses the voice instruction of the smart speaker for setting the eye protection pause timeout period, and generates a response content for setting the eye protection pause timeout period;

[0021] Step 205, the voice cloud platform transmits the response content of setting the eye protection pause timeout to the voice configuration module through the platform communication and adaptation module of the smart speaker;

[0022] Step 206, the voice configuration module transmits the configuration information of setting the eye protection pause timeout duration to the eye protection adjustment module;

[0023] Step 207: The eye protection adjustment module drives the speaker to play sound through the output drive module to inform the user that the eye protection pause timeout duration has been set.

[0024] Furthermore, the steps for the user to wake up the smart speaker are as follows:

[0025] Step 301, the wake-up word in the user's voice is converted into a digital voice signal through a digital microphone;

[0026] Step 302: The digital voice signal is acoustically processed by the input driving module and converted into a voice stream and transmitted to the platform communication and adaptation module;

[0027] Step 303, the platform communication and adaptation module sends the voice stream to the voice cloud platform;

[0028] Step 304: The voice cloud platform identifies the wake-up word in the voice stream and transmits the result of "yes, it is the wake-up word" to the platform communication and adaptation module of the smart speaker;

[0029] Step 305, the platform communication and adaptation module drives the output driving module through the voice playing module;

[0030] Step 306: The output driver module drives the speaker to play a sound to notify the user that the smart speaker is ready to receive voice commands.

[0031] Furthermore, the eye protection adjustment module segments the voice stream into N pieces, with each single sentence and title as one piece, and with a “·” between the author’s dynasty and name as one piece, and otherwise with the dynasty and name as one piece respectively. The voice stream is divided into N pieces in total.

[0032] Furthermore, the eye protection adjustment module drives the speaker to play sound and the display screen to display text through the output driving module. Before all voice streams are played, the eye protection adjustment module responds to the replay instruction at any time. The steps are as follows:

[0033] Step 401, set variable i=1;

[0034] Step 402, driving the speaker to play the i-th voice through the output driving module, driving the display screen to display the text corresponding to the i-th voice through the output driving module, and detecting whether the user presses the repeat key;

[0035] Step 403, if the playback of the i-th voice has not ended and it is detected that the user presses the repeat key, the playback of the i-th voice is ended and steps 402 to 403 are executed again;

[0036] Step 404, the playback of the i-th voice is finished, the display screen still displays the text corresponding to the i-th voice, pauses for a timeout period, and detects whether the user presses the repeat key;

[0037] Step 405, if the pause timeout period has not ended and it is detected that the user presses the repeat key, the current pause ends and steps 402 to 405 are executed again;

[0038] Step 406, pause for a timeout period;

[0039] Step 407, if i=N, execute step 408; if i≤N-1, then the variable i is incremented by 1, and steps 402 to 406 are repeated;

[0040] Step 408: Playback of all voice streams ends.

[0041] Furthermore, in the above steps, punctuation marks in the segmented speech also need to be announced.

[0042] Another object of the present invention is to provide an eye-protection smart speaker voice broadcast system, the system comprising: a voice cloud platform, a smart speaker software layer, and a smart speaker hardware layer.

[0043] The voice cloud platform is responsible for receiving the voice stream from the smart speaker platform communication and adaptation module and transmitting the response content to the smart speaker platform communication and adaptation module.

[0044] The smart speaker software layer includes: an input drive module, a platform communication and adaptation module, a voice playback module, a voice configuration module, a mode control module, an eye protection adjustment module, and an output drive module.

[0045] The input driver module is responsible for receiving the digitized voice signal from the digital microphone, performing front-end acoustic processing on the signal to form a voice stream with good sound quality, and then transmitting the voice stream to the platform communication and adaptation module.

[0046] The platform communication and adaptation module is responsible for receiving the voice stream from the input driver module and transmitting it to the voice cloud platform, and is also responsible for receiving the response content from the voice cloud platform. If the response content is a recognized wake-up word or ordinary voice stream, it is transmitted to the voice playback module; if the response content is configuration information, it is transmitted to the voice configuration module.

[0047] The voice playback module is responsible for receiving the response content from the platform communication and adaptation module. If the wake-up word is recognized, the output driver module drives the speaker to play a sound to notify the user that "the smart speaker is ready to receive voice commands"; if the wake-up word is not recognized, the response content is passed to the mode control module.

[0048] The voice configuration module is responsible for receiving configuration information from the platform communication and adaptation module, and transmitting the configuration information to the eye protection adjustment module.

[0049] The mode control module is responsible for receiving the response content from the voice playback module, and the mode is controlled by an external mode key, which is divided into normal mode and eye protection mode. The normal mode directly drives the output drive module to play, and the eye protection mode calls the eye protection adjustment module.

[0050] The eye protection adjustment module is responsible for receiving configuration information from the voice configuration module, receiving response content from the mode control module, segmenting the response content according to single sentences, adjusting the speed of the response content according to the speed configuration of the eye protection board, and repeating the response content in segments according to the repeat instructions of the eye protection board.

[0051] The output drive module is used to drive the speaker to complete voice playback and drive the display screen to display text.

[0052] The hardware layer includes: a digital microphone, a display screen, a speaker, an eye protection board, a circuit board and a casing.

[0053] The eye protection panel includes a mode key, a speed key and a repeat key. The mode key defaults to normal mode, with two gears, the left one is normal mode and the right one is eye protection mode; the speed key defaults to medium speed mode, with two gears, the left one is medium speed mode and the right one is slow mode; the repeat key defaults to a pop-up state and can be pressed, "press first, then automatically pop up", corresponding to a repeat instruction.

[0054] In response to the problem that "for homework that requires writing, when students consult the smart speaker, their writing speed cannot keep up with the voice playback speed, so they need to repeatedly ask the smart speaker, which seriously affects their learning efficiency." The present invention adds an eye-protection writing mode to traditional smart speakers, solving the problem of low learning efficiency when writing following the voice broadcast of the smart speaker.
