Detailed Description

Also, for the sake of clarity, parts not relevant to the description of the exemplary embodiments are omitted in the drawings.
In the present disclosure, it is to be understood that terms such as "including" or "having," etc., are intended to indicate the presence of the disclosed features, numbers, steps, actions, components, parts, or combinations thereof, and do not preclude the possibility that one or more other features, numbers, steps, actions, components, parts, or combinations thereof are present or added.
It should be further noted that the embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The details of the embodiments of the present disclosure are described in detail below with reference to specific embodiments.
Fig. 1 shows a flow chart of a voice navigation method according to an embodiment of the present disclosure. As shown in fig. 1, the voice navigation method includes the following steps:
in step S101, a navigation route and voice navigation content are acquired; the voice navigation content comprises voice content and voice broadcasting time;
in step S102, in the process that the navigated object travels based on the navigation route, broadcasting the voice content based on the voice broadcasting opportunity;
in step S103, after the voice content is broadcasted, the voice content at the next voice broadcasting opportunity is dynamically adjusted based on the behavior feedback information of the navigated object.
In this embodiment, the voice navigation method is executed at the navigation terminal. The voice navigation can be understood as voice-controlled navigation, which adopts representative intelligent voice technologies such as voice recognition, voice encoding and decoding, and the like, and is generally applied to vehicles, user terminals, and the like. The voice content can be understood as that in the navigation process of the navigated object, information such as the driving direction, the lane and the like of the navigated object is reminded in a voice interaction mode, namely the voice content mainly relates to guiding a navigation action which needs to be executed by a user at the upcoming moment; the voice broadcasting time can be a fixed GPS position point, after the navigation route is planned, the voice content and the voice broadcasting time are basically fixed, the navigation terminal can be matched with the voice broadcasting time based on the current positioning information of the navigated object, and the voice content corresponding to the voice broadcasting time is broadcasted in a voice mode when the navigation terminal is matched with the voice broadcasting time. It can be understood that each voice broadcast occasion may correspond to one or more candidate broadcast contents, and the navigation terminal may select one or more voice contents to broadcast randomly or according to a preset rule.
The navigated object may include a person, and the navigation terminal may include, but is not limited to, a cell phone, ipad, computer, smart watch, vehicle, robot, etc. The navigation server plans a navigation route based on the starting point and the end point and then sends the navigation route and navigation content to the navigated object. In voice navigation, the navigation content may include, but is not limited to, voice content and a voice broadcast occasion; the voice content and the voice broadcasting opportunity are correspondingly set.
And in the process that the navigated object runs based on the navigation route, the navigation terminal detects the current positioning information of the navigated object in real time, matches the positioning information with the voice broadcasting time in the voice navigation content, and broadcasts the corresponding voice content after the matching is successful.
In the embodiment of the present disclosure, each time after the voice content is reported, the navigation terminal further detects behavior feedback information of the navigated object, where the behavior feedback information may be understood as information fed back by the driving behavior of the navigated object, including but not limited to speed change information, driving direction change information, positioning information, and the like of the navigated object. The behavior feedback information of the navigated object can be detected by a vehicle driven by the navigated object or a portable handheld terminal. Whether the navigated object executes the corresponding behavior based on the currently played voice content can be judged through the behavior feedback information, if the corresponding behavior is executed, the navigated object can be considered to receive the voice content, otherwise, the navigated object can be considered not to receive the voice content. In the embodiment of the present disclosure, whether the navigated object receives the voice content may be understood as whether the user notices the current voice content and performs a corresponding action based on the voice content.
In some embodiments, the user may not be focused enough while driving, and may not be able to extract valid information from the voice content played by the navigated object, thereby easily causing a yaw to occur.
Therefore, the voice content of the next voice broadcasting opportunity can be dynamically adjusted based on the behavior feedback information of the navigated object, and the key information ignored by the user can be emphasized in the adjusted voice content, so that the yaw rate of the user is reduced by repeatedly reminding the user of the key information.
The following examples illustrate: if the corresponding voice content is played at the first voice broadcasting opportunity, the navigated object does not show corresponding driving behaviors, such as speed reduction, direction change and the like, based on the voice content; at this time, the voice content of the next voice broadcasting opportunity in the navigation can be adjusted, and if the candidate content containing the key information is selected from the plurality of voice contents corresponding to the next voice broadcasting opportunity in the predetermined voice navigation content for repeated broadcasting, other candidate contents are not broadcasted any more.
In the voice navigation, after the voice content corresponding to one voice broadcasting opportunity is broadcasted, the behavior feedback information of the navigated object is detected in real time, and the voice content corresponding to the next voice broadcasting opportunity is dynamically adjusted based on the behavior feedback information. Through the embodiment of the disclosure, the problem that the user can easily yaw by adopting the existing fixed voice broadcasting opportunity and the fixed voice content under the condition that the attention of the user is not concentrated in the driving process can be avoided, the yaw rate of the user can be reduced, and the navigation experience of the user is improved.
In an optional implementation manner of this embodiment, step S103, namely after broadcasting the voice content, dynamically adjusting the voice content at the next voice broadcasting opportunity based on the behavior feedback information of the navigated object, further includes the following steps:
after the voice content is broadcasted, detecting behavior feedback information of the navigated object;
judging whether the navigated object notices key information in the voice content or not based on the behavior feedback information;
and after determining that the navigated object does not notice the voice content, selecting the voice content comprising the key information at the next voice broadcasting opportunity to broadcast.
In the optional implementation mode, in a voice navigation scene, after the navigation server plans the navigation route, the planned navigation route and the corresponding voice navigation content are sent to the navigation terminal of the navigated object, the navigation terminal provides voice navigation service for the navigated object based on the real-time positioning information, the navigation route and the voice navigation content of the navigated object, the navigation terminal matches the real-time positioning information of the navigated object with the position point in the navigation route, and when the position point with the voice content is matched, the corresponding voice content is broadcasted in a voice mode.
The embodiment of the present disclosure considers that after the broadcasting of the voice content, the navigated object may not really receive the voice content due to the lack of attention and the like, so the behavior feedback information of the navigated object can be detected after the broadcasting of the voice content, and the behavior feedback information can include, but is not limited to, the speed change, the driving direction change and the like of the navigated object.
After determining the behavior feedback information of the navigated object, it can be determined whether the navigated object notices key information in the voice content based on the behavior feedback information, such as prompting the user to exit at a next highway junction and prompting the user to change lanes in advance in the voice content; however, the detected behavior feedback information indicates that the navigated object does not make any obvious behavior change after the voice content is played, such as no speed reduction, no direction change, etc., and at this time, it can be determined that the navigated object does not notice the key information in the voice content; conversely, if the detected behavior feedback information indicates that the navigated object has made a corresponding behavior change, such as a speed reduction, a direction change, etc., after the voice content is played, it can be determined that the navigated object has noticed key information in the voice content.
After the navigated object is determined not to notice the voice content, the voice content which only comprises the key information or can emphasize the key information can be selected for broadcasting at the next voice broadcasting occasion, so that the navigated object is reminded to pay attention to the key information. After the navigated object is determined to pay attention to the voice content, the voice content to be broadcasted can be selected at the next voice broadcasting occasion according to a conventional manner, and the voice content only including the key information or capable of emphasizing the key information is not necessarily selected, or even the voice content not including the key information can be selected, which is specifically determined according to the set selection manner of the voice content, and is not specifically limited herein.
In an optional implementation manner of this embodiment, the step of determining whether the navigated object notices key information in the voice content based on the behavior feedback information further includes the following steps:
after the voice content is broadcasted, whether the navigated object notices key information in the voice content is determined based on the matching relation between the behavior feedback information of the navigated object and the navigation action corresponding to the voice content.
In this optional implementation manner, as described above, the navigation server pushes the navigation route and the voice navigation content to the navigation terminal, where the voice navigation content includes the voice content and the voice broadcast time for playing the voice content.
After the voice content is played at the voice broadcasting opportunity, whether the voice content at the next voice broadcasting opportunity is adjusted or not is determined based on behavior feedback information of the navigated object.
In this embodiment, the navigated object may determine whether the navigated object notices key information in the voice content based on a matching relationship between the behavior feedback information of the navigated object and the navigation actions involved in the voice content. The behavior feedback information can be measured from at least two aspects, such as speed change and driving direction change of the navigated object, and the navigation action is an action to be executed by the navigated object according to the navigation route, the action is usually related to the driving direction, and since the navigated object is matched with the corresponding driving speed when executing the navigation action, the speed change, the driving direction change and the like can be mapped with the navigation action in advance, and in the navigation process, whether the navigated object notices the key information in the voice content is determined by matching the speed change, the driving change and the like in the behavior feedback information with the navigation action.
In an optional implementation manner of this embodiment, the step of determining whether the navigated object notices key information in the voice content based on a matching relationship between the behavior feedback information of the navigated object and the navigation action corresponding to the voice content further includes the following steps:
when the voice content relates to a navigation action for guiding the navigated object to turn or travel at a complex intersection, determining whether the navigated object notices key information in the voice content based on the travel speed of the navigated object.
In this optional implementation manner, the voice content corresponding to different voice broadcast occasions may be different, and the navigation action related to different voice content may also be different. The mapping relation between different navigation actions and behavior feedback information of the navigated object and the judgment conclusion of whether the navigated object notices the voice content related to the navigation action under the mapping relation can be set in advance.
In one embodiment, before a simple intersection and/or a complex intersection of a navigation route, the navigation server sets a corresponding voice broadcast time and voice content in the voice navigation content, where the voice content may relate to other navigation actions for guiding a navigated object to turn or to travel at the complex intersection (e.g., roundabout, intersection, etc.), and when the navigated object notices the voice content, the traveling speed of the navigated object usually changes, for example, the navigated object slows down to make a turn, etc., so that whether the navigated object notices key information in the voice content can be determined based on the speed change in the behavior feedback information of the navigated object.
In an optional implementation manner of this embodiment, when the voice content relates to a navigation action that guides the navigated object to turn or travel at a complex intersection, the step of determining whether the navigated object notices key information in the voice content based on the travel speed of the navigated object further includes the following steps:
and when the voice content relates to guiding the navigated object to turn, and the traveling speed of the navigated object is not reduced, determining that the navigated object does not notice key information in the voice content.
In this alternative implementation, as described above, before a simple intersection and/or a complex intersection of the navigation route, the navigation server may relate to the corresponding voice broadcast opportunity in the voice navigation content based on the voice content, where the voice content may relate to other navigation actions for guiding the navigated object to turn or to travel at the complex intersection (e.g., roundabout, intersection, etc.), and the navigated object usually has a change in its traveling speed when noticing the voice content, such as slowing down to make a turn, etc. That is, at a turn or a complex intersection, the normal driving feedback information of the navigated object at least includes a deceleration, and after the voice content is broadcasted, when the navigated object does not perform the deceleration, it can be determined that the navigated object does not notice the key information in the voice content, and the key information needs to be emphasized again at the next voice broadcasting occasion.
Fig. 2 shows a voice navigation diagram in an application scenario where a user drives an intersection near which a turn is required according to an embodiment of the present disclosure. As shown in fig. 2, when the user needs to turn near the intersection, the navigation terminal broadcasts the voice content that the place ahead needs to turn, and the driving behavior of the user that the navigation terminal obtained is: when the user does not decelerate or accelerate, the navigation terminal can judge that the attention of the user is possibly not concentrated enough and does not notice the voice content guiding the user to turn, so that the voice content continuously emphasizing the right turn is selected when the voice content is selected at the next voice broadcasting occasion, and other candidate voice contents are abandoned, thereby enhancing the reminding effect on the user.
In an optional implementation manner of this embodiment, when the voice content relates to a navigation action that guides the navigated object to turn or travel at a complex intersection, the step of determining whether the navigated object notices key information in the voice content based on the travel speed of the navigated object further includes the following steps:
when the voice content relates to a navigation action for guiding the navigated object to drive at a complex intersection, if the deceleration amplitude of the navigated object is greater than or equal to a preset speed value, determining that the navigated object notices the voice navigation content.
In this optional implementation, after the navigated object is adjacent to a complex intersection, such as a roundabout intersection or a three-way intersection, if the road shape of the intersection is unfamiliar and the key content in the intersection is not noticed after the voice content is broadcasted, a more probable behavior is a more drastic deceleration or parking, and at this time, it can be determined that the navigated object is hesitant to move in which direction because it is unclear. Therefore, the embodiment of the present disclosure may determine whether the navigated object notices the key information in the voice content based on whether the deceleration amplitude of the navigated object is greater than or equal to the preset speed value when the voice content relates to the navigation action guiding the navigated object to travel at the complex intersection based on the situation. If the deceleration amplitude is greater than or equal to the preset speed value, the navigated object can be considered to be aware of the key information in the speech content. At this time, the voice content corresponding to the next voice broadcasting opportunity can be dynamically adjusted, so that the key information is emphasized in the next voice content, and the navigated object is guided to correctly travel at the complex intersection according to the navigation route.
Fig. 3 shows a voice navigation diagram in an application scenario where a user drives near a complex intersection according to an embodiment of the present disclosure. As shown in fig. 3, when the user drives the vehicle and approaches a complex intersection (e.g., a three-way intersection), the navigation terminal broadcasts the voice content of "the front is the three-way intersection and please go to the middle lane", however, the driving behavior of the user acquired by the navigation terminal is: when the user slows down or stops the vehicle, the navigation terminal can judge that the user is hesitant and does not know which direction the user goes forward, so that the voice content emphasizing the user to go to the middle turnout can be added at the next voice broadcasting time when the voice content is selected.
In an optional implementation manner of this embodiment, the step of determining whether the navigated object notices key information in the voice content based on a matching relationship between the behavior feedback information of the navigated object and the navigation action corresponding to the voice content further includes the following steps:
when the voice content relates to a navigation action for guiding the navigated object to travel in a target lane, judging whether the navigated object is switched to the target lane based on the positioning information of the navigated object, and determining whether the navigated object notices key information in the voice content based on the judgment result.
In this alternative implementation, when the voice content relates to a navigation action for guiding the navigated object to travel on the target lane, for example, the navigated object travels at a high speed and is about to exit at a front highway exit, the voice content prompts the navigated object to merge to the rightmost lane in advance so as to exit smoothly near the highway exit. If the positioning information of the navigated object indicates that the navigated object still runs on the leftmost lane and does not slow down or change the direction (i.e. does not merge), it can be determined that the navigated object does not notice the previous voice content at this time, and therefore the voice content corresponding to the next voice broadcasting occasion can be dynamically adjusted, so as to emphasize the key information in the voice content for guiding the navigated object to merge into the lane in advance.
Fig. 4 shows a voice navigation diagram in an application scenario in which a user needs to switch lanes during driving according to an embodiment of the present disclosure. As shown in fig. 4, when the user drives a vehicle to travel in the left lane, the navigation terminal broadcasts the voice content of the right lane based on the voice broadcast time in the semantic navigation content at time t1, and when the navigation terminal determines that the user is still in the left lane according to the positioning information at time t2, the user can select the voice content continuously emphasizing the switch to the right lane for broadcast at the next voice broadcast time because the user is about to approach the intersection.
In an optional implementation manner of this embodiment, after the voice content is broadcasted, the step of dynamically adjusting the voice content at the next voice broadcasting opportunity based on the behavior feedback information of the navigated object further includes the following steps:
and after the voice content is broadcasted, adding a next voice broadcasting opportunity and a next voice content corresponding to the next voice broadcasting opportunity, wherein the added next voice content comprises key information in the voice content at least once.
In this optional implementation manner, after broadcasting a piece of voice content, the embodiment further obtains behavior feedback information of the navigated object, determines whether the navigated object notices the piece of voice content based on the behavior feedback information, and after not noticing the piece of voice content, may further dynamically adjust a next voice broadcasting opportunity and a corresponding voice content.
As described above, after planning the navigation route, the navigation server will push the navigation route and the voice navigation content to the navigation terminal. The voice navigation content comprises voice broadcasting occasions corresponding to the plurality of position points on the navigation route and at least one piece of voice content which can be broadcasted under the voice broadcasting occasions.
On the basis of the voice navigation content, the next voice broadcasting opportunity set by the navigation server and the corresponding voice content can be dynamically adjusted based on the behavior feedback information of the navigated object to the played voice content.
In some embodiments, the navigation terminal may adjust the voice content corresponding to the next voice broadcast occasion set by the navigation server based on the behavior feedback information of the navigated object, for example, a piece of voice content related to the key information in a plurality of candidate contents corresponding to the next voice broadcast occasion may be selected, or a piece of voice content emphasizing the key information may be added. In this embodiment, the next voice broadcast time may be preset by the navigation server.
In other embodiments, the navigation terminal may also adjust the next voice broadcast occasion and the corresponding voice content based on the behavior feedback information of the navigated object, that is, the navigation terminal may further add a next voice broadcast occasion and the voice content corresponding to the next voice broadcast occasion on the basis of the voice broadcast occasion set by the navigation server. The voice broadcast opportunity may be set based on the urgency of the navigation action related to the voice content missed by the navigated object, for example, in the case where the navigated object needs to perform the navigation action immediately, the voice broadcast opportunity may be set to a point in time closer to the current time, such as to perform immediately. The voice broadcast occasion may be set before a voice broadcast occasion closest to the current time in the voice navigation content. The dynamically added next voice content may be obtained by extracting key information of the voice content missed by the navigated object, and then obtaining the next voice content based on the key information, for example, the key information may be repeated at least once in the newly added next voice content.
Fig. 5 is a schematic diagram illustrating an application scenario of voice navigation according to an embodiment of the present disclosure. As shown in fig. 5, a user sends a navigation request from a current location to a destination to a navigation server through a mobile phone terminal, the navigation server plans a navigation route from the current location to the destination based on the navigation request, and pushes the planned navigation route and voice navigation content to the mobile phone terminal. After receiving the navigation route and the voice navigation content, the mobile phone terminal starts navigation based on the selection of a user, acquires the current position information of the vehicle in real time, selects at least one piece of voice content corresponding to the voice broadcasting time for broadcasting when the current position information of the vehicle is matched with the voice broadcasting time in the voice navigation content, and detects the speed change, the driving direction change and the like of the vehicle in real time after the broadcasting is completed. And judging whether the user driving the vehicle notices the key information or not based on whether the speed change, the driving direction change and the key information in the voice content are matched, and dynamically adjusting the voice broadcasting time and the corresponding voice content under the condition of not noticing so as to emphasize the key information ignored by the user again.
The following are embodiments of the disclosed apparatus that may be used to perform embodiments of the disclosed methods.
Fig. 6 shows a block diagram of a voice navigation device according to an embodiment of the present disclosure. The apparatus may be implemented as part or all of an electronic device through software, hardware, or a combination of both. As shown in fig. 6, the voice guidance apparatus includes:
an obtaining module 601 configured to obtain a navigation route and voice navigation content; the voice navigation content comprises voice content and voice broadcasting time;
the broadcasting module 602 is configured to broadcast the voice content based on the voice broadcasting opportunity in the process that the navigated object travels based on the navigation route;
the adjusting module 603 is configured to dynamically adjust the voice content of the next voice broadcasting opportunity based on the behavior feedback information of the navigated object after the voice content is broadcasted.
In this embodiment, the voice navigation apparatus is executed in the navigation terminal. The voice navigation can be understood as voice-controlled navigation, which adopts representative intelligent voice technologies such as voice recognition, voice encoding and decoding, and the like, and is generally applied to vehicles, user terminals, and the like. The voice content can be understood as that in the navigation process of the navigated object, information such as the driving direction, the lane and the like of the navigated object is reminded in a voice interaction mode, namely the voice content mainly relates to guiding a navigation action which needs to be executed by a user at the upcoming moment; the voice broadcasting time can be a fixed GPS position point, after the navigation route is planned, the voice content and the voice broadcasting time are basically fixed, the navigation terminal can be matched with the voice broadcasting time based on the current positioning information of the navigated object, and the voice content corresponding to the voice broadcasting time is broadcasted in a voice mode when the navigation terminal is matched with the voice broadcasting time. It can be understood that each voice broadcast occasion may correspond to one or more candidate broadcast contents, and the navigation terminal may select one or more voice contents to broadcast randomly or according to a preset rule.
The navigated object may include a person, and the navigation terminal may include, but is not limited to, a cell phone, ipad, computer, smart watch, vehicle, robot, etc. The navigation server plans a navigation route based on the starting point and the end point and then sends the navigation route and navigation content to the navigated object. In voice navigation, the navigation content may include, but is not limited to, voice content and a voice broadcast opportunity; the voice content and the voice broadcasting opportunity are correspondingly set.
And in the process that the navigated object runs based on the navigation route, the navigation terminal detects the current positioning information of the navigated object in real time, matches the positioning information with the voice broadcasting time in the voice navigation content, and broadcasts the corresponding voice content after the matching is successful.
In the embodiment of the present disclosure, each time after the voice content is reported, the navigation terminal further detects behavior feedback information of the navigated object, where the behavior feedback information may be understood as information fed back by the driving behavior of the navigated object, including but not limited to speed change information, driving direction change information, positioning information, and the like of the navigated object. The behavior feedback information of the navigated object can be detected by a vehicle driven by the navigated object or a portable handheld terminal. Whether the navigated object executes the corresponding behavior based on the currently played voice content can be judged through the behavior feedback information, if the corresponding behavior is executed, the navigated object can be considered to receive the voice content, otherwise, the navigated object can be considered not to receive the voice content. In the embodiment of the present disclosure, whether the navigated object receives the voice content may be understood as whether the user notices the current voice content and performs a corresponding action based on the voice content.
In some embodiments, the user may not be focused enough while driving, and may not be able to extract valid information from the voice content played by the navigated object, thereby easily causing a yaw to occur.
Therefore, the voice content of the next voice broadcasting opportunity can be dynamically adjusted based on the behavior feedback information of the navigated object, and the key information ignored by the user can be emphasized in the adjusted voice content, so that the yaw rate of the user is reduced by repeatedly reminding the user of the key information.
The following examples illustrate: if the corresponding voice content is played at the first voice broadcasting opportunity, the navigated object does not show corresponding driving behaviors, such as speed reduction, direction change and the like, based on the voice content; at this time, the voice content of the next voice broadcasting opportunity in the navigation can be adjusted, and if the candidate content containing the key information is selected from the plurality of voice contents corresponding to the next voice broadcasting opportunity in the predetermined voice navigation content for repeated broadcasting, other candidate contents are not broadcasted any more.
In the voice navigation, after the voice content corresponding to one voice broadcasting opportunity is broadcasted in the voice navigation process based on the navigation route and the voice navigation content sent by the navigation server, the behavior feedback information of the navigated object is detected in real time, and the voice content corresponding to the next voice broadcasting opportunity is dynamically adjusted based on the behavior feedback information. Through the embodiment of the disclosure, the problem that the user can easily yaw by adopting the existing fixed voice broadcasting opportunity and the fixed voice content under the condition that the attention of the user is not concentrated in the driving process can be avoided, the yaw rate of the user can be reduced, and the navigation experience of the user is improved.
In an optional implementation manner of this embodiment, the adjusting module includes:
the first determining submodule is configured to detect behavior feedback information of the navigated object after the voice content is broadcasted;
a first judging sub-module configured to judge whether the navigated object notices key information in the voice content based on the behavior feedback information;
and the selection submodule is configured to select the voice content including the key information for broadcasting at the next voice broadcasting opportunity after the fact that the voice content is not noticed by the navigated object is determined.
In the optional implementation mode, in a voice navigation scene, after the navigation server plans the navigation route, the planned navigation route and the corresponding voice navigation content are sent to the navigation terminal of the navigated object, the navigation terminal provides voice navigation service for the navigated object based on the real-time positioning information, the navigation route and the voice navigation content of the navigated object, the navigation terminal matches the real-time positioning information of the navigated object with the position point in the navigation route, and when the position point with the voice content is matched, the corresponding voice content is broadcasted in a voice mode.
The embodiment of the present disclosure considers that after the broadcasting of the voice content, the navigated object may not really receive the voice content due to the lack of attention and the like, so the behavior feedback information of the navigated object can be detected after the broadcasting of the voice content, and the behavior feedback information can include, but is not limited to, the speed change, the driving direction change and the like of the navigated object.
After determining the behavior feedback information of the navigated object, it can be determined whether the navigated object notices key information in the voice content based on the behavior feedback information, such as prompting the user to exit at a next highway junction and prompting the user to change lanes in advance in the voice content; however, the detected behavior feedback information indicates that the navigated object does not make any obvious behavior change after the voice content is played, such as no speed reduction, no direction change, etc., and at this time, it can be determined that the navigated object does not notice the key information in the voice content; conversely, if the detected behavior feedback information indicates that the navigated object has made a corresponding behavior change, such as a speed reduction, a direction change, etc., after the voice content is played, it can be determined that the navigated object has noticed key information in the voice content.
After the navigated object is determined not to notice the voice content, the voice content which only comprises the key information or can emphasize the key information can be selected for broadcasting at the next voice broadcasting occasion, so that the navigated object is reminded to pay attention to the key information. After the navigated object is determined to pay attention to the voice content, the voice content to be broadcasted can be selected at the next voice broadcasting occasion according to a conventional manner, and the voice content only including the key information or capable of emphasizing the key information is not necessarily selected, or even the voice content not including the key information can be selected, which is specifically determined according to the set selection manner of the voice content, and is not specifically limited herein.
In an optional implementation manner of this embodiment, the first determining sub-module includes:
and the second determining sub-module is configured to determine whether the navigated object notices key information in the voice content based on the matching relation between the behavior feedback information of the navigated object and the navigation action corresponding to the voice content after the voice content is broadcasted.
In this optional implementation manner, as described above, the navigation server pushes the navigation route and the voice navigation content to the navigation terminal, where the voice navigation content includes the voice content and the voice broadcast time for playing the voice content.
After the voice content is played at the voice broadcasting opportunity, whether the voice content at the next voice broadcasting opportunity is adjusted or not is determined based on the behavior feedback information of the navigated object.
In this embodiment, the navigated object may determine whether the navigated object notices key information in the voice content based on a matching relationship between the behavior feedback information of the navigated object and the navigation actions involved in the voice content. The behavior feedback information can be measured from at least two aspects, such as speed change and driving direction change of the navigated object, and the navigation action is an action to be executed by the navigated object according to the navigation route, the action is usually related to the driving direction, and since the navigated object is matched with the corresponding driving speed when executing the navigation action, the speed change, the driving direction change and the like can be mapped with the navigation action in advance, and in the navigation process, whether the navigated object notices the key information in the voice content is determined by matching the speed change, the driving change and the like in the behavior feedback information with the navigation action.
In an optional implementation manner of this embodiment, the second determining sub-module includes:
a third determination submodule configured to determine whether the navigated object notices key information in the voice content based on a travel speed of the navigated object when the voice content relates to a navigation action that guides the navigated object to turn or travel at a complex intersection.
In this optional implementation manner, the voice content corresponding to different voice broadcast occasions may be different, and the navigation action related to different voice content may also be different. The mapping relation between different navigation actions and behavior feedback information of the navigated object and the judgment conclusion of whether the navigated object notices the voice content related to the navigation action under the mapping relation can be set in advance.
In one embodiment, before a simple intersection and/or a complex intersection of a navigation route, the navigation server sets a corresponding voice broadcast time and voice content in the voice navigation content, where the voice content may relate to other navigation actions for guiding a navigated object to turn or to travel at the complex intersection (e.g., roundabout, intersection, etc.), and when the navigated object notices the voice content, the traveling speed of the navigated object usually changes, for example, the navigated object slows down to make a turn, etc., so that whether the navigated object notices key information in the voice content can be determined based on the speed change in the behavior feedback information of the navigated object.
In an optional implementation manner of this embodiment, the third determining sub-module includes:
a fourth determination sub-module configured to determine that the navigated object is not paying attention to key information in the voice content, in a case where the traveling speed of the navigated object is not reduced while the voice content is involved in guiding the navigated object to turn.
In this alternative implementation, as described above, before a simple intersection and/or a complex intersection of the navigation route, the navigation server may relate to the corresponding voice broadcast opportunity in the voice navigation content based on the voice content, where the voice content may relate to other navigation actions for guiding the navigated object to turn or to travel at the complex intersection (e.g., roundabout, intersection, etc.), and the navigated object usually has a change in its traveling speed when noticing the voice content, such as slowing down to make a turn, etc. That is, at a turn or a complex intersection, the normal driving feedback information of the navigated object at least includes a deceleration, and after the voice content is broadcasted, when the navigated object does not perform the deceleration, it can be determined that the navigated object does not notice the key information in the voice content, and the key information needs to be emphasized again at the next voice broadcasting occasion.
In an optional implementation manner of this embodiment, the third determining sub-module includes:
a fifth determining sub-module, configured to determine that the navigated object notices the voice navigation content if the deceleration amplitude of the navigated object is greater than or equal to a preset speed value when the voice content relates to a navigation action for guiding the navigated object to drive at a complex intersection.
In this optional implementation, after the navigated object is adjacent to a complex intersection, such as a roundabout intersection or a three-way intersection, if the road shape of the intersection is unfamiliar and the key content in the intersection is not noticed after the voice content is broadcasted, a more probable behavior is a more drastic deceleration or parking, and at this time, it can be determined that the navigated object is hesitant to move in which direction because it is unclear. Therefore, the embodiment of the present disclosure may determine whether the navigated object notices the key information in the voice content based on whether the deceleration amplitude of the navigated object is greater than or equal to the preset speed value when the voice content relates to the navigation action guiding the navigated object to travel at the complex intersection based on the situation. If the deceleration amplitude is greater than or equal to the preset speed value, the navigated object can be considered to notice key information in the speech content. At this time, the voice content corresponding to the next voice broadcasting opportunity can be dynamically adjusted, so that the key information is emphasized in the next voice content, and the navigated object is guided to correctly travel at the complex intersection according to the navigation route.
In an optional implementation manner of this embodiment, the second determining sub-module includes:
a second determination sub-module configured to, when the voice content relates to a navigation action that guides the navigated object to travel in a target lane, determine whether the navigated object switches to the target lane based on the positioning information of the navigated object, and determine whether the navigated object notices key information in the voice content based on the determination result.
In this alternative implementation, when the voice content relates to a navigation action for guiding the navigated object to travel on the target lane, for example, the navigated object travels at a high speed and is about to exit at a front highway exit, the voice content prompts the navigated object to merge to the rightmost lane in advance so as to exit smoothly near the highway exit. If the positioning information of the navigated object indicates that the navigated object still runs on the leftmost lane and does not slow down or change the direction (i.e. does not merge), it can be determined that the navigated object does not notice the previous voice content at this time, and therefore the voice content corresponding to the next voice broadcasting occasion can be dynamically adjusted, so as to emphasize the key information in the voice content for guiding the navigated object to merge into the lane in advance.
In an optional implementation manner of this embodiment, the adjusting module includes:
and the adding submodule is configured to add a next voice broadcasting opportunity and next voice content corresponding to the next voice broadcasting opportunity after the voice content is broadcasted, and the added next voice content at least comprises key information in the voice content once.
In this optional implementation manner, after broadcasting a piece of voice content, the embodiment further obtains behavior feedback information of the navigated object, determines whether the navigated object notices the piece of voice content based on the behavior feedback information, and after not noticing the piece of voice content, may further dynamically adjust a next voice broadcasting opportunity and a corresponding voice content.
As described above, after planning the navigation route, the navigation server will push the navigation route and the voice navigation content to the navigation terminal. The voice navigation content comprises voice broadcasting occasions corresponding to the plurality of position points on the navigation route and at least one piece of voice content which can be broadcasted under the voice broadcasting occasions.
On the basis of the voice navigation content, the next voice broadcasting opportunity set by the navigation server and the corresponding voice content can be dynamically adjusted based on the behavior feedback information of the navigated object to the played voice content.
In some embodiments, the navigation terminal may adjust the voice content corresponding to the next voice broadcast occasion set by the navigation server based on the behavior feedback information of the navigated object, for example, a piece of voice content related to the key information in a plurality of candidate contents corresponding to the next voice broadcast occasion may be selected, or a piece of voice content emphasizing the key information may be added. In this embodiment, the next voice broadcast time may be preset by the navigation server.
In other embodiments, the navigation terminal may also adjust the next voice broadcast occasion and the corresponding voice content based on the behavior feedback information of the navigated object, that is, the navigation terminal may further add a next voice broadcast occasion and the voice content corresponding to the next voice broadcast occasion on the basis of the voice broadcast occasion set by the navigation server. The voice broadcast opportunity may be set based on the urgency of the navigation action related to the voice content missed by the navigation object, for example, in the case where the navigation action needs to be immediately performed by the navigation object, the voice broadcast opportunity may be set to a point in time closer to the current time, such as immediate execution or the like. The voice broadcast occasion may be set before a voice broadcast occasion closest to the current time in the voice navigation content. The dynamically added next voice content may be obtained by extracting key information of the voice content missed by the navigated object, and then obtaining the next voice content based on the key information, for example, the key information may be repeated at least once in the newly added next voice content.
