To further illustrate the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide the method operation steps as shown in the following embodiments or figures, more or less operation steps may be included in the method based on the conventional or non-inventive labor. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application.
The following describes the technical solution provided in the embodiment of the present application with reference to the application scenario shown in fig. 1. Any robot tone automatic switching method provided by the embodiment of the application can be executed by a controller inside the robot or a background server controlling the robot, and is not limited.
Referring to fig. 2, an embodiment of the present application provides a robot tone automatic switching method, including the following steps:
s201, responding to an instruction of the first robot entering the working state, and identifying whether a second robot in the working state exists in a preset distance around the first robot.
In specific implementation, when the robot identifies a user or service requirements, the robot enters a working state; when the robot does not provide service for any user, the robot is in an idle state, and the robot does not emit voice at this time. If the robot in the working state does not execute a specific task and does not receive the operation and instruction of the user and the like after the preset time length is exceeded, the robot can enter an idle state. It should be noted that, in the present application, both the first robot and the second robot may refer to any robot in a scene.
In specific implementation, after the first robot enters a working state, the position information of the first robot and other robots is obtained, the distance between the first robot and other robots is calculated, candidate robots with the distance smaller than a preset distance are screened out, the states of the candidate robots are obtained, and the candidate robots in the working state are used as second robots. Or after the first robot enters the working state, finding out the robots in the working state, acquiring the position information of the robots and the first robot, calculating the distance between the first robot and the robots, and screening out the robots with the distance smaller than the preset distance to serve as second robots.
S202, if it is determined that the second robot in the working state exists in the preset distance around the first robot, a second tone currently used by the second robot is obtained.
And S203, switching the tone of the first robot to a tone different from the second tone.
In specific implementation, a plurality of candidate timbres are configured in advance for selection by the robot.
In practical applications, one or more second robots may be identified through step S201, and it is necessary to acquire all currently used timbres of the second robots, exclude the currently used timbres of the second robots from preset candidate timbres, and select an appropriate timbre from the remaining candidate timbres as the timbre of the first robot. When no second robot satisfying the condition is identified, the first robot may select an appropriate tone color from the preset candidate tone colors.
It should be noted that, the steps shown in fig. 2 generally need to be completed before the first robot provides the voice service for the current user, and in order to ensure the user experience, except for special cases (if the user requires to change the tone), the first robot does not change the tone after selecting the tone to be used until the service of the current user is finished. The first robot may enter an idle state after finishing providing services for the current user, wait to be awakened again by other users, and enter a working state again after being awakened again, at this time, the tone used needs to be determined again according to the steps shown in fig. 2.
According to the automatic robot tone switching method, the robots in the working states nearby are immediately searched after the first robot enters the working states, the tone used by the robots is obtained, the robots are prevented from using the same tone to conduct voice broadcasting, the voice output by the robots is prevented from being influenced mutually, the user can well distinguish the sounds of different robots, and user experience is improved.
Further, step S203 specifically includes: from a plurality of candidate timbres other than the second timbre, a candidate timbre whose pitch matches the disturbing factor is selected as the timbre of the first robot.
Wherein, an initial tone is configured for each candidate tone in advance, for example, candidate tone a1 is male bass, and its initial tone is 90 Hz; candidate timbre A2 is the male mediant, with an initial pitch of 120 Hz; candidate timbre a3 is a female treble with an initial pitch of 220 Hz.
The interference factors comprise at least one of the volume of the environment around the first robot, the number of people and the number of interference sources, and the selected tones are positively correlated with the volume of the environment, the number of people and the number of interference sources. With the same noise interference, it is easier for the user to hear the speech with the higher pitch.
In specific implementation, the ambient volume around the robot can be detected through equipment such as a microphone and a decibel meter. If the environment volume is higher, selecting candidate timbres with higher tone from the selectable candidate timbres as the timbres used by the first robot; if the ambient volume is low, the candidate timbre with lower pitch is selected from the selectable candidate timbres as the timbre used by the first robot. The matching relationship between the environmental volume and the tone can be set according to application requirements, and is not limited.
In specific implementation, the number of people around the robot can be identified through equipment such as a camera and an infrared sensor. If the number of people around the robot is large, selecting candidate timbres with higher tones from the selectable candidate timbres as the timbres used by the first robot; if the number of people around the robot is small, a candidate timbre with a lower pitch is selected from the selectable candidate timbres as the timbre used by the first robot. The matching relationship between the number of people around the robot and the tone can be set according to the application requirements, and is not limited.
In specific implementation, referring to fig. 3, the activity space of the robot includes various sound interference sources 103, such as a number-calling device, a printer, a fountain landscape, an air conditioner, etc., and noise in the external space may interfere with the indoor space through doors and windows, etc. The position information of the interference sources can be marked in advance and added into indoor map data of the robot, the robot 101 can acquire the real-time position of the robot in the activity space through indoor positioning technology, inertial navigation technology, laser radar and other technologies, and the number of the surrounding interference sources can be determined according to the indoor map data and the real-time position. If the number of interference sources around the robot is large, selecting candidate timbres with higher tones from the selectable candidate timbres as the timbres used by the first robot; if the number of interference sources around the robot is small, a candidate timbre with a lower pitch is selected from the selectable candidate timbres as the timbre used by the first robot. The matching relationship between the number of interference sources around the robot and the tones may be set according to application requirements, and is not limited.
In practical application, a possible interference source in the activity space can be determined in advance according to decibel values sent by all equipment in the activity space of the robot when working, if the decibel value sent by the equipment when working exceeds a noise decibel value, the equipment is used as the interference source, otherwise, the equipment is not used as the interference source.
It should be noted that some interference sources may make sounds at irregular time, that is, it is impossible to predict in advance when the interference sources will make sounds, which belongs to sudden noise interference, and the number of interference sources around the robot is known in advance, so that the noise interference that may be encountered in the future is predicted, and then the tone of the matching tone is selected, and it is ensured that the user can hear the voice of the robot clearly under the noise interference.
On the basis of any embodiment, after the tone used by the first robot is determined, the first robot may further acquire the ambient volume around the first robot during the operation process, and adjust the tone and/or volume of the first robot according to the ambient volume.
Specifically, taking the adjustment of the tone as an example, if the volume of the environment around the first robot is adjusted to be greater than the noise threshold, the tone of the first robot is increased, wherein the volume of the environment is positively correlated to the increased tone. That is, based on the initial tone corresponding to the tone color selected by the first robot, the tone of the robot is appropriately increased according to the volume of the environment. When the volume of the environment around the robot is detected to be reduced, the tone of the robot can be reduced. The value of the noise threshold can be set according to actual requirements, and is not limited.
For example, the initial tone of the timbre selected by the first robot is 100Hz, and the tone of the first robot may be increased when the volume of the environment around the first robot is greater than the noise threshold by 70 db. Specifically, detecting that the decibel number of the ambient volume around the first robot is V (the unit is decibel), and when V is more than or equal to 70 and less than 75, increasing the tone of the first robot to 200 Hz; when V is more than or equal to 75 and less than 80, the tone of the first robot is increased to 300 Hz; when V is more than or equal to 80 and less than 85, the tone of the first robot is increased to 400 Hz; when V is more than or equal to 85 and less than 90, the tone of the first robot is increased to 500 Hz; when V is larger than or equal to 90, the tone of the first robot is increased to 600 Hz.
When a decrease in the volume of the environment surrounding the first robot is detected, the pitch value of the first robot is correspondingly decreased.
Specifically, taking volume adjustment as an example, if the volume adjustment of the environment around the first robot is greater than the noise threshold, the volume of the first robot is increased, where the volume of the environment is positively correlated to the increased volume. When the volume of the environment around the robot is detected to be reduced, the volume of the robot can be reduced.
For example, the decibel number of the detected environment volume is V (the unit is decibel), and when V is more than or equal to 70 and less than 75, the output volume is automatically increased by 10 percent of the maximum volume; when V is more than or equal to 75 and less than 80, the output volume is automatically increased by 20 percent of the maximum volume; when V is more than or equal to 80 and less than 85, the output volume is automatically increased by 30 percent of the maximum volume; when V is more than or equal to 85 and less than 90, the output volume is automatically increased by 40 percent of the maximum volume; when V is more than or equal to 90, the noise affects the normal hearing of human, so that the adjusting volume of the robot can only stay at 40% of the maximum. The maximum volume may be an upper limit of the volume set for the robot, such as 100 db.
When a decrease in the volume of the environment surrounding the first robot is detected, the volume value of the first robot is correspondingly decreased.
In practical application, the tone and the volume of the first robot can be simultaneously increased according to the environmental volume, and the identifiability of the robot voice is improved from two dimensions.
On the basis of any one of the above embodiments, after the tone used by the first robot is determined, the first robot may further identify the number of people around the first robot during the operation, and if the number of people around the first robot is greater than a preset number of people, the tone and/or volume of the first robot is increased.
Specifically, the output tone of the robot can be increased according to the number of people around the robot, that is, the more people around the robot, the higher the output tone of the robot, and the relationship between the number of recognized people and the output volume can be set according to the actual application requirements. For example, the initial tone of the timbre selected by the first robot is 100Hz, the number of people around the first robot is identified as H, and when H is more than or equal to 8 and less than 13, the tone of the first robot is increased to 300 Hz; when H is more than or equal to 13, the tone of the first robot is increased to 500 Hz.
Specifically, the output volume of the robot can be increased according to the number of people around the robot, that is, the output volume of the robot is higher as the number of people around the robot is larger, and the relationship between the number of recognized people and the output volume can be set according to the actual application requirements. For example, the number of people around the robot is identified as H, and when H is more than or equal to 8 and less than 13, the output volume is automatically increased by 15 percent of the maximum volume; when H is more than or equal to 13, the output volume is automatically increased by 30 percent of the maximum volume.
Before the robot is ready to play voice, if the robot recognizes that the environment volume at the site does not meet the requirement of volume adjustment, but the situation that the number of people at the site is large, the current state is quite quiet and noise is generated at the next moment can occur, the robot just starts to output voice due to the time difference of the noise generation, the voice and the noise are mixed, so that a user cannot hear the voice content, when the number of people around the robot is large, the output volume of the robot is properly increased, and the possible noise can be judged in advance.
When a decrease in the number of people around the first robot is detected, the volume and/or volume of the first robot may be decreased accordingly.
Referring to fig. 3, the activity space of the robot can be divided into interference areas 104 and quiet areas 105 according to the distribution of the interference sources, wherein the quiet areas 105 do not include the interference sources, and each interference area 104 includes at least one interference source 103. Specifically, a circle can be drawn by taking the interference source 103 as a circle center and a preset value as a radius, an area inside the circle is taken as an interference area, and an area outside the circle is taken as a quiet area. Further, the radius of the circle may be determined according to the decibel value of the noise generated by each of the interferers 103, and the higher the decibel value of the noise, the longer the radius. The radius of the circle can be selected according to experience and in combination with practical application scenes, and is not limited. In specific implementation, the area division data of the motion space of the robot can be added into the indoor map data of the robot, the robot 101 can acquire the real-time position of the robot in the motion space through indoor positioning technology, inertial navigation technology, laser radar and other technologies, and the current area is determined according to the area division data and the real-time position in the indoor map data.
In practical applications, the interference source includes at least one of the following: the noise space is communicated with the moving space of the robot, and equipment capable of emitting interference noise can be arranged in the moving space. When the isolation device between the active area of the robot and the noise space is opened, the noise space is in an interference state, and when the isolation device between the active area and the noise space is closed, the noise space is in a non-interference state. The noise space is relative to the activity space, which may be an outdoor road, or may be a room containing a noise source and communicating with the activity space of the robot, for example, the activity space of the robot includes a hall, a walkway, etc., the region of the projection room, etc., is a noise space, and the isolation device is openable and closable, including but not limited to a door, a window, etc.
Therefore, after the tone used by the first robot is determined, the first robot can also determine a target area where the first robot is located currently according to the position information of the first robot in the running process; and if the target area is determined to be the interference area, increasing the tone and/or volume of the first robot.
According to the distribution situation of interference sources in the activity space, the activity space is divided into an interference area containing the interference sources and a quiet area not containing the interference sources, the area where the robot is located is determined by detecting real-time position information of the robot, the tone and/or volume of the robot playing voice can be properly improved after the robot enters the interference area from the quiet area, the tone and/or volume of the robot playing voice are reduced after the robot enters the quiet area from the interference area, the fact that a user can hear the voice played by the robot clearly is guaranteed, and the comfort of the user in listening to the voice is improved. Therefore, the method for automatically switching the sound colors of the robot can predict the noise interference which may occur in advance according to the area where the robot is located, so that the volume of the robot is adjusted to a proper value in advance, and even if the interference source suddenly emits the noise interference, a user can be ensured to clearly hear the voice played by the robot.
Further, if the target area is determined to be the interference area, the target number of the interference sources in the interference state in the target area is obtained, and the tone value and/or the volume value which needs to be increased by the first robot is determined according to the target number.
The increased tone value of the first robot is positively correlated with the target number, and the tone value that the first robot needs to increase is also positively correlated with the target number, that is, the more the number of the interference sources in the interference state in the target interference area is, the larger the increased tone value and the increased tone value of the robot are. Taking the tone as an example, when the target number is 0, the tone is increased by 50 Hz; when the target number is 1, the tone is increased by 100 Hz; when the target number is 2, the pitch is increased by 150 Hz. Therefore, the tone and the volume of the robot can be improved in a grading way according to the number of the interference sources in the interference state, and the comfort of a user for listening to the voice is improved.
When a decrease in the target number of interferers in an interfering state within the target area is detected, the tone value and/or volume value of the first robot is correspondingly decreased to provide the most comfortable and clear voice service to the user.
When the interference source in the target interference area is a noise space, the image acquisition device of the robot can be controlled to shoot the image of the isolation device in the target interference area, whether the isolation device in the target interference area is opened or not is identified based on the shot image, and whether the isolation device is opened or not can be specifically determined through an existing image identification algorithm. Or, the distance from the robot to the isolation device can be measured based on the distance measuring device of the robot, that is, a signal is transmitted to the isolation device in the target interference area; if the signal reflected by the isolation device is not received or the distance from the robot to the isolation device is calculated according to the reflected signal and does not accord with the actual distance, the isolation device is determined to be opened, and then the noise space is determined to be in an interference state; and if the distance from the robot to the isolating device is calculated according to the reflected signals and is in accordance with the actual distance, determining that the isolating device is in a closed state, and further determining that the noise space is in a non-interference state. Wherein the actual distance between the robot and the interference source may be determined based on the position information of the robot and the position information of the interference source.
When the interference source in the target interference area is equipment capable of emitting interference noise, the ambient volume around the robot can be detected, and when the decibel of the ambient volume exceeds the noise decibel value, the interference source is determined to be in an interference state. If the indicating lamp for indicating whether the equipment works exists on the equipment, the robot can judge the working state of the equipment by identifying the state of the indicating lamp. If the equipment is intelligent equipment controlled by the background server, the working state of the equipment can be obtained through the background server.
In practical application, the relevant detection in the above embodiment can be performed before the robot plays the voice every time, the tone and/or the volume of the robot are adjusted to a proper value, and then the robot is controlled to play the voice with the proper volume and the proper tone until the robot completes the voice broadcast, so that the situation that the volume of the robot is suddenly increased in the process of playing the voice can be avoided, and better listening experience is brought to a user.
To avoid the superposition of volume and pitch increments caused by multiple detection factors, the priority of each detection mode can be set. For example, the environmental volume around the robot is detected first, if the environmental volume is greater than the noise threshold, the volume and/or tone of the robot are directly increased according to the environmental volume, and other factors are not detected, if the environmental volume does not exceed the noise threshold, the number of people around the robot is continuously detected; if the number of people is larger than the preset number of people, the tone and/or the volume of the first robot are/is increased, other factors are not detected, if the number of people does not exceed the preset number of people, the number of the interference sources in the area where the first robot is located and the number of the interference sources in the area are continuously detected, and the tone and/or the volume of the first robot is adjusted. The method combines the priority ranking of various factors such as environment volume, the number of people on site, the area where the robot is located and the like, gives a reasonable judgment flow, avoids the operation of volume superposition under various conditions, adjusts the volume of the robot more reasonably, and improves the flexibility of the voice function of the robot.
In practical application, the volume and the upper limit value of the tone can be set, if the volume increased by the robot exceeds the volume upper limit value, the volume of the robot can be forcibly modified to the volume upper limit value, and overhigh output volume is avoided, and similarly, if the volume increased by the robot exceeds the tone upper limit value, the tone of the robot can be forcibly modified to the tone upper limit value, and overhigh output tone is avoided.
