Detailed Implementation

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the absence of conflict, the following embodiments and their technical features can be combined with each other.

[0019] The first aspect of this application provides a wearable device, which may include wrist-worn wearable devices such as smartwatches.

[0020] refer to Figure 1 As shown, the wearable device includes a processor 110, a status recognition module 120, a wireless communication module 130, and a voice playback module 140. The processor 110 can be connected to the status recognition module 120, the wireless communication module 130, and the voice playback module 140, respectively.

[0021] The wireless communication module 130 is used to receive first voice information sent by an external device and send the first voice information to the processor 110. The external device includes at least one of the following electronic devices capable of communicating with wearable devices: smartphones, Bluetooth headsets, smartwatches, and walkie-talkies. Optionally, the wireless communication module 130 may include a classic Bluetooth communication module, a low-power Bluetooth communication module, a UWB (Ultra-Wideband) communication module, and / or Wi-Fi communication, etc., which are short-range wireless communication modules capable of stable wireless communication with external devices.

[0022] The state recognition module 120 is used to identify the first-level state information between the wearable device and the designated user body part, and upload the first-level state information to the processor 110. The designated user body part can be determined according to the type of wearable device. For example, if the wearable device is a wrist-worn device such as a smart bracelet, the designated user body part can include the head, and the corresponding first-level state information can include proximity and distance states, etc. In this case, the state between the wearable device and the user's head is used to determine whether the user is easily affected by external interference when listening to and / or inputting corresponding voice information. Optionally, the state recognition module 120 can be implemented using related sensors or other components to typically detect the state of the user's hand or other body part wearing the wearable device and / or the relative state between the wearable device body part and the designated user body part to determine the corresponding first-level state information.

[0023] The processor 110 is used to determine the second-level state information of the wearable device—intercom state and non-intercom state—based on the first-level state information. In the intercom state, it sends first voice information to the voice playback module 140, enabling the voice playback module 140 to play the received first voice information when external environmental interference is relatively weak, thereby improving the playback effect of the first voice information. The processor 110 is also used to save the first voice information and output a prompt message in the non-intercom state to notify the user that the first voice information has been received. Optionally, the processor 110 can control the wearable device's display screen, vibration module, and / or related playback components to output corresponding prompt messages; for example, the processor 110 can control the display screen to light up and / or flash to output corresponding prompt messages; or the processor 110 can control the vibration module to vibrate to output corresponding prompt messages; or the processor 110 can control related playback components to play prompt sounds to output corresponding prompt messages, etc.

[0024] The voice playback module 140 may include components such as speakers and / or loudspeakers for playing voice information. The voice playback module 140 is used to play received voice information (such as first voice information, etc.).

[0025] The wearable device includes a two-way communication mode and a non-two-way communication mode. In the two-way communication mode, the wearable device receives the first voice information sent by another two-way communication end (i.e., an external device) and plays the first voice information directly to quickly provide the two-way communication function. In the non-two-way communication mode, the wearable device saves the first voice information and outputs a prompt message to inform the user that the first voice information has been received. This allows the first voice information to be played again when the user needs to obtain it or when the device enters the two-way communication mode later, ensuring the playback quality of the first voice information and optimizing the user experience brought by the two-way communication function.

[0026] In the aforementioned wearable device, the processor 110 can determine the intercom state and non-intercom state based on the first-level state information. In the intercom state, it sends the first voice information to the voice playback module 140, so that the voice playback module 140 can play the received first voice information when the external environmental interference is relatively weak, thereby improving the playback effect of the first voice information, avoiding interference from the external environment when playing the first voice information, and improving the convenience and reliability of the user when using the intercom function of the wearable device.

[0027] In some embodiments, the first-level state information includes a proximity state. Optionally, the first-level state information may also include other state information such as a distance state. A proximity state indicates that the wearable device is close to the designated user area, facilitating the user to listen to voice information and / or input voice information into the wearable device. A distance state indicates that the wearable device is far from the designated user area, making it susceptible to external environmental interference if the user listens to voice information and / or inputs voice information into the wearable device.

[0028] The processor 110 is also configured to control the wearable device to enter intercom mode when it receives the first voice information, the wearable device is in close proximity to the designated user's body part, and the current state is not intercom mode, thereby providing intercom functionality and responding to the user's intercom needs. Specifically, the conditions for entering intercom mode include: a. the wireless communication module receives the first voice information sent by an external device (indicating intercom needs); b. the first-level state information is in close proximity (indicating intercom mode); when both a and b are satisfied, if the wearable device was originally in non-intercom mode, the processor 110 can control the corresponding wearable device to enter intercom mode.

[0029] In some examples, after receiving the above prompt, the user can bring the wearable device close to the designated user area by raising their hand or other actions. At this time, the processor 110 can acquire this first-level status information of proximity, determine that the conditions for intercom are met, and control the wearable device to enter intercom mode. When the processor 110 recognizes the intercom mode, it sends the saved first voice information to the voice playback module 140, causing the voice playback module 140 to automatically play the first voice information. When playing the first voice information, interference from the external environment is relatively small, and the user can hear the first voice information more clearly.

[0030] In some examples, if a user believes that the current environment is suitable for listening to the corresponding first voice information after receiving the above prompt information, they can input a playback command to the wearable device. At this time, the processor 110 is also used to send the saved first voice information to the voice playback module 140 when it recognizes the playback command input by the user or when the wearable device enters the intercom state from the non-intercom state. This allows the voice playback module 140 to switch the playback of the first voice information according to the user command or the state of the wearable device. While ensuring the playback effect, this also improves the flexibility of the playback response function.

[0031] In some embodiments, such as Figure 2 As shown, the wearable device also includes a voice acquisition module 150; the voice acquisition module 150 may include components such as a microphone for acquiring voice information.

[0032] The processor 110 is also used to send a wake-up command to the voice acquisition module 150 when the wearable device is in close proximity to the designated user part or when the wearable device is in intercom mode, so that the voice acquisition module 150 is in a wake-up state and has the function of real-time acquisition of voice information.

[0033] The voice acquisition module 150 receives the wake-up command, acquires the second voice information input by the user, and sends the second voice information to the 110.

[0034] The processor 110 is also used to send the second voice information to an external device through the wireless communication module 130 when receiving the second voice information sent by the voice acquisition module, so as to realize the intercom function between the wearable device and the external device.

[0035] Optionally, the processor 110 is further configured to disable the voice acquisition module 150 when the wearable device is far from the designated user's body or when the wearable device exits the intercom state, to prevent the voice acquisition module 150 from acquiring invalid voice information. Optionally, the wearable device may automatically exit the intercom state when it is far from the designated user's body, or it may exit the intercom state upon receiving an exit command input by the user. Optionally, the exit command may include gesture commands, voice commands, press commands, and / or touch commands, etc., to instruct the wearable device to exit the intercom state.

[0036] In some examples, the processor 110 is further configured to determine whether the second voice information has preset voice features when receiving the second voice information. If the second voice information has the preset voice features, the processor 110 sends the second voice information to the wireless communication module 130 so that the wireless communication module 130 sends the second voice information to the corresponding external device so that the second voice information is valid voice and ensures the effectiveness of the intercom function.

[0037] Optionally, the preset voice features include feature information indicating that the second voice information originates from a user using a wearable device. The presence of preset voice features in the second voice information indicates that the second voice information has valid voice features. Optionally, the processor 110 may pre-store preset voice features such as reference audio and / or specific voice feature information to determine whether the second voice information possesses preset voice features. Optionally, the processor 110 may determine whether the second voice information possesses preset voice features using methods such as voice recognition and / or voiceprint recognition. For example, the processor 110 may recognize the voiceprint features of the second voice information. When the voiceprint features of the second voice information match the voiceprint features of the reference audio and / or pre-stored voiceprint features, the processor 110 determines that the second voice information possesses preset voice features.

[0038] In some embodiments, the wearable device includes a wrist-worn device such as a smartwatch, and the designated user part includes the head. When the wrist-worn wearable device is brought close to the user's head, the wearable device can automatically enter intercom mode. At this time, the corresponding user is more likely to hear the first voice signal, and external environmental interference is relatively weak when listening to the first voice signal. On the other hand, it is also beneficial to the privacy of the intercom process, making it difficult for others to hear the intercom content, and also protecting others from interference during the intercom process.

[0039] In some examples, the state recognition module 120 includes an inertial sensor.

[0040] The inertial sensor is used to identify the wrist-raising motion information of the wrist wearing the wrist wearable device and send the wrist-raising motion information to the processor 110.

[0041] The processor 110 is also used to identify first-level state information between the wearable device and the designated user part based on the hand-raising action information; for example, an inertial sensor can perform gesture recognition (such as determining the hand-raising action) so that the processor 110 can determine the proximity action of the wrist wearable device to the wearer's head.

[0042] Specifically, inertial sensors can include accelerometers (measuring linear acceleration), gyroscopes (measuring angular velocity), and magnetometer sensors. One or more of the following. An inertial sensor can identify corresponding hand-raising motion information based on the position change of the wrist-worn wearable device (the position change can be measured by the inertial sensor). For example, if the inertial sensor detects an upward displacement greater than a first displacement threshold (such as threshold 1), it can determine that the user is currently raising their hand, and thus acquire the corresponding hand-raising motion information. The hand-raising motion information can be characterized by inertial sensor data (such as acceleration and / or angular velocity data). At this time, the processor 110 can use a neural network (such as a lightweight CNN or Transformer model) to determine the proximity motion between the wrist-worn wearable device and the wearer's head. Optionally, the processor 110 can first train on the user's hand gestures. For hand gestures where the distance between the wrist-worn wearable device and the wearer's head is less than a second displacement threshold (such as threshold 2), it can be determined that the wrist-worn wearable device and the wearer's head are approaching each other, and at this time, the wrist-worn wearable device and the wearer's head are in a proximity state. Optionally, the aforementioned proximity motion can be at least one condition for determining the proximity state.

[0043] Optionally, there can also be a distance movement between the wrist wearable device and the wearer's head. The distance movement is used to determine that the wrist wearable device and the wearer's head are in a distance state. For example, the processor 110 can also determine that for those gestures where the distance between the wrist wearable device and the wearer's head is greater than a third displacement threshold (such as a threshold greater than 2, such as 4), the wrist wearable device and the wearer's head are in a distance state.

[0044] In practical applications, besides the near and far states between the wrist-worn wearable device and the wearer's head, there are other states that are neither near nor far. Most of the time, the relationship between the wrist-worn wearable device and the wearer's head can be identified as one of these other states. In these other states, the wrist-worn wearable device will not switch between intercom and non-intercom modes.

[0045] In some examples, the state recognition module 120 includes a camera.

[0046] The camera is used to collect image information and send the image information to the processor.

[0047] The processor 110 is further configured to identify the location information of the wearable device based on the image information, and determine the first-level state information between the wearable device and a designated user body part based on the location information.

[0048] Optionally, the processor 110 can identify the position of the wrist-worn wearable device based on image information captured by the camera, and determine the proximity action between the wrist-worn wearable device and the wearer's head. The processor 110 can employ a neural network, such as a deep learning model like CNN or Transformer, to determine the proximity action between the wrist-worn wearable device and the wearer's head based on the image information captured by the camera. Optionally, the processor 110 can also first train on the user's hand gestures, identifying gestures where the distance between the wrist-worn wearable device and the wearer's head is less than a preset distance threshold (e.g., a threshold of 2) as proximity actions, and train the model based on the captured image information. Optionally, the processor 110 can also identify stationary targets in the image information captured by the camera, and based on these stationary targets, determine the position and / or pose of the wrist-worn wearable device, identify the proximity action between the wrist-worn wearable device and the wearer's head, and thus determine the proximity state between the wrist-worn wearable device and the wearer's head. Optionally, the processor 110 can also identify the movement of the wrist wearable device away from the wearer's head based on image information and stationary targets, thereby determining the distance between the wrist wearable device and the wearer's head.

[0049] Optionally, the processor 110 can also acquire external images captured by another external device including a camera, and identify the position of the wrist-worn wearable device based on the external images to determine the approach movement of the wrist-worn wearable device to the wearer's head. The acquired external images include the wrist-worn wearable device worn by the user, thus allowing the identification of positional changes of the wrist-worn wearable device based on the images, thereby identifying the approach movement of the wrist-worn wearable device to the wearer's head. The wrist-worn wearable device and the other external device including the camera can be wirelessly connected; the wireless connection can be Bluetooth, for example, using Bluetooth channel sounding technology to identify the position of the wrist-worn wearable device. The wireless connection can also be Wi-Fi, using Wi-Fi's CSI (Channel State Information) to identify the position of the wrist-worn wearable device. The wireless connection can also be UWB, using UWB positioning to identify the position of the wrist-worn wearable device.

[0050] Optionally, when outputting a prompt message, the processor 110 can activate the camera of the wearable device on the wrist, so that the camera can collect corresponding image information in real time, identify the position information of the wearable device on the wrist, and determine whether the wearable device on the wrist is approaching the wearer's head.

[0051] In the above wearable device, the wireless communication module 130 can receive the first voice information sent by an external device, and the status recognition module 120 can recognize the first-level status information between the wearable device and the designated user part. The processor 110 determines the second-level status information, namely the intercom status and the non-intercom status, based on the first-level status information. In the intercom status, the processor 110 sends the first voice information to the voice playback module 140, so that the voice playback module 140 plays the received first voice information when the external environmental interference is relatively weak, thereby improving the playback effect of the first voice information and avoiding interference from the external environment when the wearable device plays the first voice information, thus improving the convenience and reliability of the user when using the intercom function of the wearable device.

[0052] Specifically, the processor 110 can also save the first voice information and output a prompt message when not in intercom mode to inform the user that the first voice information has been received. After receiving the prompt message, the user can bring the wearable device and the designated user body part into a close proximity state by raising their hand or other actions. At this time, the wearable device can automatically enter intercom mode based on the proximity state and other information. When the processor 110 recognizes that the wearable device has entered intercom mode, it can send the saved first voice information to the voice playback module 140, so that the voice playback module 140 can automatically play the first voice information based on the first-level state information between the wearable device and the designated user body part. Moreover, when playing the first voice information, the interference caused by the external environment is relatively small, and the user can listen to the first voice information more clearly.

[0053] A second aspect of this application provides a voice information processing method, which is applied to the wearable device described in any of the above embodiments. (Reference) Figure 3 As shown, the voice information processing method includes steps S210 to S240.

[0054] S210 receives the first voice message sent by an external device.

[0055] S220, Identify the first-level status information between the wearable device and the designated user part.

[0056] S230, determine the intercom state and non-intercom state based on the first-level state information. In the intercom state, directly play the first voice information. In the non-intercom state, save the first voice information and output a prompt message.

[0057] The above-described voice information processing method, when applied to the wearable device described in any of the above embodiments, has all the beneficial effects of the wearable device described in any of the aforementioned embodiments, and will not be repeated here.

[0058] A third aspect of this application provides an intercom system, the intercom system including the wearable device described in any of the above embodiments.

[0059] Optionally, refer to Figure 4 As shown, the intercom system may also include intercom terminals other than the wearable devices mentioned above. These intercom terminals, as external devices to the wearable devices, can be at least one of terminals such as mobile phones, earphones, watches, and walkie-talkies. The wearable devices mentioned above can be wrist-worn devices, which can be at least one of devices such as smartwatches, sports watches, and wristbands.

[0060] In practical applications, wrist-worn wearable devices and walkie-talkie terminals can be pre-paired to enable intercom communication. Wrist-worn wearable devices can also be paired with multiple walkie-talkie terminals simultaneously to enable intercom communication with multiple terminals at the same time.

[0061] The above-mentioned intercom system includes the wearable device described in any of the above embodiments, and has all the beneficial effects of the wearable device described in any of the foregoing embodiments, which will not be repeated here.
