In view of the above problems, the present application provides a method for controlling voice playing, and the following describes an embodiment of the present application in detail with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a schematic flow chart of a voice play control method provided in an embodiment of the present application, and is applied to an electronic device, where the electronic device includes a main body, a first pan-tilt speaker and a second pan-tilt speaker that are disposed on the main body, and at least two camera devices that are disposed on the main body, and as shown in the drawing, the voice play control method includes:
s201, the electronic equipment acquires image information of a target user through the at least two camera devices;
wherein the body includes an upper end surface, a lower end surface, and a plurality of side end surfaces.
The number of the side end surfaces is not specifically limited, for example, 3, 4, or another number, where the number of the imaging devices is not specifically limited, for example, one imaging device may be arranged on each side end surface, a plurality of imaging devices may be arranged on each side end surface, or an imaging device may be arranged on a part of side end surfaces of the plurality of side end surfaces, so that the plurality of imaging devices arranged on the electronic device can acquire image data of a horizontal 360-degree space, and tracking of a target person in a signal coverage range is achieved.
For example, the electronic device may be four side end surfaces, and includes an image pickup device disposed on the front end surface and an image pickup device disposed on the rear end surface, where the image pickup device disposed on the front end surface and the image pickup device disposed on the rear end surface are used to track a target person in a horizontal 360-degree space.
Therefore, in the example, the electronic equipment can acquire the image information of the target user through the at least two camera devices arranged on the body so as to ensure the timeliness and the authenticity of the source of the image information.
S202, the electronic equipment determines the actual state of the target user according to the image information;
wherein, the actual state of the target user may be the following three types: the first pan/tilt speaker is being used, the first pan/tilt speaker is not being used, and the first pan/tilt speaker and the second pan/tilt speaker are suspended from being used.
In a specific implementation, when a target user is asleep, determining that the target user does not use the first pan-tilt speaker and the second pan-tilt speaker; determining that the target user suspends the use of the first pan-tilt speaker and the second pan-tilt speaker under the condition that the target user uses the mobile phone; and under the condition that the target user does not use the mobile phone and is not asleep, determining that the target user is using the first pan-tilt speaker and the second pan-tilt speaker.
Therefore, in this example, the electronic device can determine the actual state of the user according to the image information of the user, and the intelligence of the electronic device is improved.
S203, the electronic equipment adjusts the working states of the first holder loudspeaker and the second holder loudspeaker according to the actual state of the target user.
Wherein the first pan-tilt speaker and the second pan-tilt speaker may be full-range speakers; the first pan-tilt speaker and the second pan-tilt speaker may also be tweeters; the first pan-tilt speaker and the second pan-tilt speaker may be tweeters, and the second pan-tilt speaker may be full-range speakers; the first pan-tilt speaker and the second pan-tilt speaker may be driven by a motor in the electronic device to rotate at multiple angles in the left-right direction or the up-down direction according to the corresponding requirement.
Wherein the arrangement of the first pan-tilt speaker and the second pan-tilt speaker is not particularly limited, for example, the first pan tilt speaker and the second pan tilt speaker may be both disposed on the upper end surface of the main body, the first pan tilt speaker and the second pan tilt speaker may be both disposed on the lower end surface of the main body, the first pan tilt speaker may be disposed on the upper end surface of the main body, the second pan-tilt speaker is arranged on the lower end surface of the main body and can be arranged in other modes, and the specific positions where the first pan-tilt speaker and the second pan-tilt speaker are disposed are not limited, such as when the first pan-tilt speaker and the second pan-tilt speaker are disposed at the same end face, the end face may be symmetrically disposed on the left and right sides of the end face, or asymmetrically disposed on the left and right sides of the end face, and is not particularly limited.
For example, the electronic device is a projector, please refer to fig. 3, and fig. 3 is a schematic structural diagram of the projector, as shown in fig. 3, the projector includes a main body, and the first pan tilt speaker and the second pan tilt speaker are symmetrically disposed on an upper end surface of the main body.
Therefore, in this example, the electronic device can analyze the actual state of the user through the image information of the user, and adjust the working state of the speaker based on the actual state of the user, so that the intelligence of controlling the speaker in the electronic device is improved, and the experience of the user is further improved.
In one possible example, the determining, by the electronic device, the actual state of the target user according to the image information includes: the electronic equipment determines whether the action of the target user is to make a call; if the action of the target user is not a call, the electronic equipment determines whether the motion state of the target user is a static state; if the motion state of the target user is a static state, the electronic equipment determines whether the posture of the target user meets a first condition, wherein the first condition is used for restraining the posture of the target user to be a sitting posture or a sleeping posture; if the posture of the target user meets the first condition, the electronic equipment determines whether the eye state of the target user meets a second condition, wherein the second condition is used for restraining the eye state of the target user to be a closed eye state, and the corresponding duration exceeds a preset duration; if the eye state of the target user meets the second condition, the electronic device determines that the actual state of the target user is that the first pan-tilt speaker and the second pan-tilt speaker are not used.
The implementation manner of the electronic device determining whether the action of the target user is to make a call may be: the electronic device determines that the target user holds the communication device in hand, and presses the communication device close to the ear to present the action of answering the phone call. The communication device may be a cell phone, a landline phone, a telephone watch, or the like.
The preset time may be 1 minute, the preset time may also be two minutes, and the preset time may also be other times, which is not specifically limited.
In a specific implementation, when the preset time is 1 minute, the electronic device determines whether the motion state of the target user is a stationary state when determining that the motion state of the target user is not a call, then determines whether the posture of the target user is a sitting posture or a sleeping posture when determining that the motion state of the target user is the stationary state, then further monitors the eye state of the user when determining that the posture of the target user is the sitting posture or the sleeping posture, and determines that the eye state of the target user is an eye-closed state and the eye-closed state exceeds 1 minute, that is, it is determined that the actual state of the target user is that the first pan-tilt speaker and the second pan-tilt speaker are not used.
In this example, it can be seen that, in a case where it is determined that the motion of the user is not a call, the electronic device is capable of determining whether the motion state of the target user is a stationary state, then, in a case where it is determined that the motion state of the target user is the stationary state, then, determining whether the posture of the user is a sitting posture or a sleeping posture, in a case where it is determined that the posture of the target user is the sitting posture or the sleeping posture, further, monitoring the eye state of the user, and when it is determined that the eye state of the target user is an eye-closed state and the eye-closed state exceeds a preset time, determining that the actual state of the user is that the first pan-tilt speaker and the second pan-tilt speaker are not used.
In one possible example, after the electronic device determines whether the action of the target user is to make a call, the method further comprises:
and if the action of the target user is calling, the electronic equipment determines that the actual state of the target user is that the first holder loudspeaker and the second holder loudspeaker are suspended.
As can be seen, in this example, the electronic device is capable of determining that the actual state of the user is the suspension of using the first pan-tilt speaker and the second pan-tilt speaker when it is determined that the user is making a call based on the image information of the user.
In one possible example, after the electronic device determines whether the motion state of the target user is a static state if the action of the target user is not to make a call, the method further includes:
and if the motion state of the target user is not a static state, the electronic equipment determines that the actual state of the target user is that the first pan-tilt speaker and the second pan-tilt speaker are being used.
That is, when the motion state of the target user is a non-stationary state, that is, when the position of the target user changes, it is determined that the actual state of the target user is using the first pan-tilt speaker and the second pan-tilt speaker.
As can be seen, in this example, the electronic device may determine that the actual state of the user is the suspension of using the first pan-tilt speaker and the second pan-tilt speaker when it is determined that the user moves based on the image information of the user.
In one possible example, after the electronic device determines whether the gesture of the target user satisfies the first condition if the motion state of the target user is a stationary state, the method further includes:
if the posture of the target user does not satisfy the first condition, the electronic device determines that the actual state of the target user is that the first pan-tilt speaker and the second pan-tilt speaker are being used.
In specific implementation, if the target user is not in the sitting posture or the sleeping posture, such as a half-squatting posture, a full-squatting posture or a standing posture, it is determined that the user is using the first pan-tilt speaker and the second pan-tilt speaker.
As can be seen, in this example, the electronic device is capable of determining that the user is actually using the first pan-tilt speaker and the second pan-tilt speaker when it is determined that the user is not making a call and is not moving based on the image information of the user and the postures are not the postures of the sitting posture and the sleeping posture.
In one possible example, after the electronic device determines whether the eye state of the target user satisfies a second condition if the gesture of the target user satisfies the first condition, the method further includes:
if the eye state of the target user does not satisfy the second condition, the electronic device determines that the actual state of the target user is that the first pan-tilt speaker and the second pan-tilt speaker are being used.
In a specific implementation, when the preset time is 1 minute, under the condition that it is determined that the target user does not make a call and the posture is the sleeping posture or the sitting posture, if it is monitored that the eyes of the target user are opened after closing the eyes for 15s, it is determined that the actual state of the target user is that the first pan-tilt speaker and the second pan-tilt speaker are being used.
As can be seen, in this example, the electronic device is further capable of recognizing that the user is in a stationary state when it is determined that the user is not making a call based on the image information of the user, and determining that the actual state of the user is that the first pan-tilt speaker and the second pan-tilt speaker are suspended when the eye state of the user is in the eye-closed state for no longer than a preset time period.
In one possible example, the adjusting, by the electronic device, the working states of the first pan-tilt speaker and the second pan-tilt speaker according to the actual state of the target user includes:
if it is determined that the actual state of the target user is that the first pan-tilt speaker and the second pan-tilt speaker are not used, the electronic device generates a first instruction for adjusting the first pan-tilt speaker and the second pan-tilt speaker so as to close the first pan-tilt speaker and the second pan-tilt speaker;
if it is determined that the actual state of the target user is that the first pan-tilt speaker and the second pan-tilt speaker are suspended from being used, the electronic device generates a second instruction for adjusting the first pan-tilt speaker and the second pan-tilt speaker so as to close the first pan-tilt speaker and the second pan-tilt speaker, or enable the first pan-tilt speaker and the second pan-tilt speaker to face other directions except the direction of the target user;
if the actual state of the target user is determined to be that the first holder speaker and the second holder speaker are being used, the electronic device generates a third instruction for adjusting the first holder speaker and the second holder speaker, so that the first holder speaker and the second holder speaker face the target user, and the playing volume is the target volume.
Specifically, for example, the first pan-tilt speaker and the second pan-tilt speaker may both face the direction other than the direction of the target user and have an included angle with the direction of the target user greater than any other direction of a first angle value, the first angle value may be 60 degrees, the first angle value may also be 90 degrees, the first angle value may be other angle values, and the first pan-tilt speaker and the second pan-tilt speaker may both face the direction opposite to the direction of the target user.
Wherein the target volume is a volume associated with a distance between the electronic device and a target user, in a specific implementation, the larger the distance between the electronic device and the target user, the higher the target volume, the smaller the distance between the electronic device and the target user, and the lower the target volume, so as to achieve the same sound effect that the target user hears at different positions, and the function associated with the distance between the electronic device and the target user and the target volume can be turned on and off as required, it can be understood that, when the function associated with the distance between the electronic device and the target user and the target volume is not turned on, the first pan-tilt speaker and the second pan-tilt speaker do not change due to the change of the distance between the electronic device and the target user, and when the function associated with the distance between the electronic device and the target user and the target volume is turned on, the first pan-tilt speaker and the second pan-tilt speaker may vary with a distance between the electronic device and a target user.
Specifically, for example, the first pan-tilt speaker and the second pan-tilt speaker may both face the direction other than the direction of the target user and have an included angle with the direction of the target user greater than any other direction of a first angle value, the first angle value may be 60 degrees, the first angle value may also be 90 degrees, the first angle value may be other angle values, and the first pan-tilt speaker and the second pan-tilt speaker may both face the direction opposite to the direction of the target user.
As can be seen, in this example, the electronic device can perform different adjustments on the working states of the first pan-tilt speaker and the second pan-tilt speaker in different actual states of the user, and specifically, can close the first pan-tilt speaker and the second pan-tilt speaker when it is determined that the actual state of the user is that the first pan-tilt speaker and the second pan-tilt speaker are not used; determining that the actual state of the user is that the first pan-tilt speaker and the second pan-tilt speaker are suspended, or closing the first pan-tilt speaker and the second pan-tilt speaker, or making the first pan-tilt speaker and the second pan-tilt speaker face other directions except the direction of the target user; and when the actual state of the target user is determined to be that the first holder loudspeaker and the second holder loudspeaker are used, the first holder loudspeaker and the second holder loudspeaker face the target user, and the playing volume is the target volume.
In one possible example, if it is determined that the actual state of the target user is using the first pan-tilt speaker and the second pan-tilt speaker, the electronic device generates a third instruction for adjusting the first pan-tilt speaker and the second pan-tilt speaker, including: the electronic device determining a head position of the target user; the electronic equipment determines a first target direction of the first pan-tilt loudspeaker according to the head position, wherein the first target direction is a direction facing the head position; the electronic equipment determines a second target direction of the second pan-tilt loudspeaker according to the head position, wherein the second target direction is a direction facing the head position; the electronic equipment determines a target distance from a local terminal to the head of the target user; the electronic equipment determines target volume according to the target distance and a first preset relation, wherein the first preset relation is a corresponding relation between the distance and the volume; and the electronic equipment generates a third instruction according to the first target direction, the second target direction and the target volume so as to adjust the orientation of the first holder loudspeaker and the second holder loudspeaker to the target user, and the playing volume is the target volume.
The first target direction and the second target direction may be the same, for example, the first target direction is an opposite direction of the target user with respect to the direction in which the first pan-tilt speaker is located, the second target direction is an opposite direction of the target user with respect to the direction in which the second pan-tilt speaker is located, and the first target direction and the second target direction may be different, for example, the first target direction is an opposite direction of the target user with respect to the direction in which the first pan-tilt speaker is located, and the second target direction is any direction having an included angle of 90 degrees with the direction in which the target user with respect to the second pan-tilt speaker is located.
In a specific implementation, the first preset relationship may be a corresponding relationship between a plurality of volume gears and a plurality of distance ranges. As shown in Table 1, volume level 1 corresponds to a first volume value X 1 First volume value X 1 Corresponding to a first distance range [0, a); volume gear 2 corresponds to a second volume value X 2 Second volume value X 2 Corresponding to the second distanceOff range [ a, b); volume gear 3 corresponds to a second volume value X 3 Second volume value X 3 Corresponding to a second distance range [ b, c); volume gear 4 corresponds to a second volume value X 4 Second volume value X 4 Corresponding to a second distance range [ c, d); volume gear 5 corresponds to a second volume value X 5 Second volume value X 5 Corresponding to a second distance range [ d, + infinity](ii) a The first volume value is smaller than the second volume value, the second volume value is smaller than the third volume value, the third volume value is smaller than the fourth volume value, the fourth volume value is smaller than the fifth volume value, wherein a is larger than 0, a is smaller than b, b is smaller than c, and c is smaller than d. Each corresponding relationship is data obtained based on an experiment, or is obtained based on profiling statistics of the target user, that is, statistics of the use habits of the target user, and is not particularly limited.
TABLE 1
As can be seen, in this example, when the actual state of the user is that the first pan-tilt speaker and the second pan-tilt speaker are being used, the electronic device controls the first pan-tilt speaker to face the head of the user, controls the second pan-tilt speaker to face the head of the user, determines the distance from the local end to the head of the target user, and adjusts the playing volume of the first pan-tilt speaker and the second pan-tilt speaker based on the distance.
In one possible example, after the image information of the target user is acquired by the at least two cameras, the method further includes: if the actual state of the target user is not identified according to the image information, a fourth instruction for adjusting the first holder loudspeaker and the second holder loudspeaker is generated, so that the first holder loudspeaker and the second holder loudspeaker face towards the right front.
It should be noted that, when the user can set that the electronic device is in the power-on state, the first pan-tilt speaker and the second pan-tilt speaker are default to face the front, and the direction is a common direction scene.
It can be seen that, in this example, when the actual state of the target user is not recognized, the electronic device may control the first pan-tilt speaker and the second pan-tilt speaker to face the front, so as to improve the intelligence of the electronic device.
Referring to fig. 4, fig. 4 is a schematic flowchart of another voice playing control method provided in the embodiment of the present application, and is applied to an electronic device, as shown in fig. 4, the voice playing control method includes:
