Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or server that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The customized voice materials are used for navigation broadcasting, personalized requirements of users can be met, and the electronic map and related navigation equipment are in the development direction. The voice material can include voice material, voice broadcast parameter two parts, and the broadcast sound of different voice material can be different to report concrete content and also can be different.

In the prior art, various customized voice material packets can be provided for a user so that the user can select the voice material packets according to needs, but the technical scheme has certain difficulties in use in navigation equipment:

first, important information may be missed. The customized voice material selected by the user in the existing navigation device can mostly only be ensured to be used for voice broadcasting at the beginning or the end of navigation. For example, the customized voice material selected by the user a is broadcasted with the sound of lingering in the beginning of navigation, namely 'navigation is started, and a safety belt is tied'; the customized voice material selected by the user B is broadcasted by the sound of guo german when the navigation is finished, "the navigation is finished this time", but the navigation process does not necessarily ensure that the customized voice material is used to broadcast the whole navigation information, so as to prevent missing important information, and the whole navigation information broadcast means that the customized voice material is used to broadcast the whole navigation. The reason for this is that the vehicle does not necessarily have enough running time to play the content corresponding to the navigation information in the customized voice material for the link where the navigation information needs to be played.

For example, if the user a needs to play three pieces of information, namely, a down tunnel, an out tunnel, and a left turn, in the driving process of a certain road segment R, the total broadcast information amount should include three parts, namely, the down tunnel, the out tunnel, and the left turn. However, the content corresponding to the three pieces of information in the customized phonetic material installation package selected by the user a is three short sentences: "enter the tunnel ahead, please turn on the car light", "the vehicle has gone out of the lane", "turn left ahead, please notice the vehicle behind". It can be seen that there are many contents to be played according to the selection of the user, and if the voice broadcast speed specified in the customized voice material packet is slow, the user a may not be able to play the three phrases during the driving process of the road segment R.

In order to reduce the probability of missing important information, in the prior art, customized voice materials are usually selected to be used only at the beginning or the end of navigation, or even if the customized voice materials are used in the navigation process, the customized voice materials are not allowed to be switched according to the actual driving condition, or the contents which cannot be played completely are directly abandoned in the navigation process.

Second, adaptive selection of customized speech material is not possible. The customized voice materials in the prior art depend on user-defined settings, and the granularity of the user-defined settings is generally thicker, so that the customized voice materials cannot be adaptively selected. The user can set navigation through a user-defined mode to uniformly use a certain customized voice material, but if the user is required to set the customized voice material for each different scene through a defined mode, obviously, the operation path of the user is increased, and the user experience is reduced.

As shown in fig. 1, to solve the above problem, an embodiment of the present invention first provides a schematic diagram of an adaptive navigation voice broadcast operating environment, where the adaptive navigation voice broadcast operating environment includes a operation control platform 01, a capability component 02, and a navigation voice broadcast terminal 03.

The operation control platform 01 may include a server operating independently, or a distributed server, or a server cluster composed of a plurality of servers. The operation and control platform can construct figures for each user with the navigation voice broadcast terminal, set self-adaptive navigation voice broadcast strategies for the users according to the figures, and send the strategies to the capability component 02 or the navigation voice broadcast terminal 03.

The navigation voice broadcast terminal 03 is in bidirectional communication connection with the operation and control platform 01, and may be an entity device of a type such as a smart phone, a tablet computer, a notebook computer, a vehicle-mounted terminal, a digital assistant, an intelligent wearable device, or may include software running in the entity device, such as an application program. The navigation voice broadcast terminal 03 can perform self-adaptive navigation voice broadcast for the user.

The capability component 02 comprises a first subcomponent 021 and a second subcomponent 022, both of which subcomponent 021 and 022 are communicatively connected to the navigation voice announcement terminal 03. The first subcomponent 021 and the second subcomponent 022 may be built in the navigation voice broadcast terminal 03, or built in the operation and control platform 01, or set up in the cloud to interact with the navigation voice broadcast terminal 03 in the form of an independent server.

The first subcomponent 021 stores all customized voice materials, can acquire voices to be played according to the customized voice materials and the adaptive navigation voice broadcast strategy, and transmits the voices to be played to the navigation voice broadcast terminal 03.

The second sub-component 022 can calculate the time required by the voice playing to be played in real time, selects the voice actually played for the user by combining the current navigation scene, and transmits the voice actually played to the navigation voice broadcast terminal 03, and the setting of the second sub-component 022 can reduce the probability of missing important information.

As shown in fig. 2, an embodiment of the present invention provides a method for adaptive navigation voice broadcast, where the method may be implemented by taking an entirety formed by each component in an environment where the adaptive navigation voice broadcast is executed as a main body, and the method includes:

s101, the navigation voice broadcasting terminal acquires navigation basic information and sends the navigation basic information to a running control platform.

Specifically, the navigation basic information includes at least a navigation start point and a navigation end point.

S102, the operation and control platform acquires a navigation scene sequence according to the navigation basic information, acquires a configuration file according to the navigation scene sequence, and sends the configuration file to the navigation voice broadcast terminal; the configuration file comprises a basic broadcast file and a voice broadcast strategy, wherein the voice broadcast strategy is used for describing a replacement strategy for replacing the linguistic data in the basic broadcast file by using customized voice materials under each navigation scene in the navigation scene sequence.

Specifically, the operation and control platform may obtain the navigation route according to actual navigation basic information, and of course, may also obtain a plurality of navigation routes, and determine the navigation route that is finally selected by the user in an interactive manner with the navigation voice broadcast terminal.

And obtaining a navigation scene sequence according to the navigation route and/or the current navigation scene. Specifically, the navigation scenes may be divided according to a preset scene division rule, and one or more navigation scenes may be hit in the current navigation scene and in the process of driving along the navigation route, so as to obtain a navigation scene sequence, where the navigation scene sequence at least includes one navigation scene. The speech sound materials used in different navigation scenarios can be different, and therefore, the speech sound broadcasting strategy can support one basic broadcasting file to broadcast by using a plurality of speech sound materials.

Specifically, the scene division rule in the embodiment of the present invention is not specifically limited. The navigation scene division can be carried out according to time, places and feature items, the feature items can include whether the navigation scene division is carried out in a city commonly used by a user or not, whether the navigation route spans over 100 kilometers or not, whether the navigation is day or night when the navigation is started, whether the navigation is long or false or not and the like, and various navigation scenes such as long distance, short distance, driving at night in the day, traveling in other places and the like can be obtained. During the navigation, switching of navigation scenes can be generated, such as driving across provinces and holidays.

As shown in fig. 3, the obtaining of the configuration file according to the navigation scene sequence may include:

and S1021, obtaining a first strategy related to the user characteristic image according to the user characteristic image.

Specifically, the first strategy is not related to the navigation route, but related to the portrait of the user, and can be used for voice broadcasting at the beginning or the end of the navigation. For example, if the user portrays a star, and the user likes a star, the audio material recorded by the star may be broadcasted at the beginning or end of the navigation.

And S1022, obtaining a second strategy irrelevant to the characteristic image of the user according to the navigation scene sequence.

Specifically, the navigation scene sequence may be obtained according to various parameters such as a fixed city, a fixed province, a fixed user, a fixed festival, seasonal attributes, feature items, the current navigation route, and the like, and a second policy corresponding thereto may be obtained.

For example, during the national festival, the speech sound materials conforming to the national festival scene are broadcasted; if the user is not in the common city, broadcasting the voice materials which accord with the different domain business scene; and if the user is in the middle of long-distance driving and walks to Shandong province, the voice material recorded by a certain star in the Shandong province is broadcasted.

And S1023, combining the first strategy and the second strategy to obtain a voice broadcast strategy.

And S1024, obtaining a basic broadcast file according to the navigation scene sequence.

And S1025, writing the voice broadcast strategy and the basic broadcast file into a configuration file.

S103, the navigation voice broadcasting terminal obtains replacement broadcasting audio, and the replacement broadcasting audio is obtained according to the basic broadcasting file and the voice broadcasting strategy.

Specifically, the navigation voice broadcast terminal can acquire the replacement broadcast audio through interaction with the capability component. And a first sub-component in the capability component stores all customized voice materials, and selects content matched with the basic broadcast file in the voice materials according to the voice broadcast strategy to form the replacement broadcast audio. The customized phonetic material may be star recorded audio.

Specifically, the replacement broadcast audio can be sent to the navigation voice broadcast terminal in the form of an audio list, and when the navigation voice broadcast terminal is in actual use, the navigation voice broadcast terminal downloads the audio list from the first sub-assembly.

In a feasible implementation manner, the replacement broadcast audio can be acquired at the beginning of navigation, the information to be broadcast is acquired according to the basic broadcast file and the navigation route, and the replacement broadcast audio is acquired according to the information to be broadcast and the voice broadcast strategy.

In another feasible implementation manner, the replacement broadcast audio can be acquired in real time in the navigation process, the information to be broadcast is acquired according to the basic broadcast file and the current navigation route, and the replacement broadcast audio is acquired according to the information to be broadcast and the voice broadcast strategy.

And S104, the navigation voice broadcasting terminal acquires the content to be broadcasted of the current navigation scene, acquires a target audio from the replacement broadcast audio according to the content to be broadcasted, and broadcasts the target audio.

Specifically, on the premise that the playing time is sufficient, the replacement broadcast audio may be played all, but when the playing time is not sufficient, the audio with a higher priority may be played preferentially. The priority of each message to be broadcasted is recorded in the content to be broadcasted, and when the broadcasting time is insufficient, the audio with high priority is selected to be broadcasted preferentially.

The embodiment of the invention discloses a self-adaptive navigation voice broadcasting method which can automatically switch voice materials according to different scenes in a navigation process so as to realize diversified voice material broadcasting, and important information is prevented from being omitted by setting a second component and broadcasting the voice materials according to different priorities in combination with the current navigation scene. Compared with the prior art, the embodiment of the invention can replace the voice material at any link in the whole navigation process, provide better driving safety guidance, improve driving interestingness and improve user viscosity.

In a feasible embodiment provided by the present invention, a method for adaptive navigation voice broadcast is provided, where the method may be implemented by taking as a main body an entirety formed by each component in the above-mentioned adaptive navigation voice broadcast operating environment, as shown in fig. 4, and includes:

s201, the navigation voice broadcasting terminal obtains navigation basic information and sends the navigation basic information to a running control platform.

S202, the operation and control platform acquires a navigation scene sequence according to the navigation basic information, acquires a configuration file according to the navigation scene sequence, and sends the configuration file to the navigation voice broadcast terminal; the configuration file comprises a basic broadcast file and a voice broadcast strategy, wherein the voice broadcast strategy is used for describing a replacement strategy for replacing the linguistic data in the basic broadcast file by using customized voice materials under each navigation scene in the navigation scene sequence.

And S203, the navigation voice broadcasting terminal transmits the configuration file to a first sub-assembly and requests the first sub-assembly to return an audio list corresponding to the configuration file.

Specifically, the resource corresponding to the audio list may be downloaded to the navigation voice broadcast terminal locally, so as to facilitate subsequent playing. For example, if the subsequent target broadcast content needs to use the resource in the audio list, the subsequent target broadcast content can be directly used.

And S204, the navigation voice broadcasting terminal acquires the content to be played of the current navigation scene from the second sub-assembly and transmits the content to be played to the first sub-assembly.

S205, the navigation voice broadcast terminal acquires a target broadcast audio based on interaction with a first sub-component, and the target broadcast audio is obtained according to the content to be broadcast, the basic broadcast file and the voice broadcast strategy.

Specifically, according to a voice broadcasting strategy and a basic broadcasting file, voice materials are used for replacing contents to be played to obtain audio to be played, and the target playing audio is extracted from the audio to be played by comprehensively considering the current running condition. Other embodiments may be referred to for a specific manner of obtaining the target playing audio.

And S206, the navigation voice broadcasting terminal broadcasts the target broadcast audio.

The embodiment of the invention can acquire the target broadcast audio in real time based on the content to be played in the navigation process, and can be used independently or combined with the previous embodiment based on the same inventive concept as the previous embodiment.

The embodiment of the present invention further provides another adaptive navigation voice broadcasting method, where the method uses a navigation voice broadcasting terminal as an execution main body, and is based on the same inventive concept as the system embodiment, as shown in fig. 5, the method includes:

s301, acquiring navigation basic information.

S302, acquiring a configuration file according to the navigation basic information; the configuration file comprises a basic broadcast file and a voice broadcast strategy, wherein the voice broadcast strategy is used for describing a replacement strategy for replacing the linguistic data in the basic broadcast file by using customized voice materials under each navigation scene in the navigation scene sequence.

And S303, acquiring a target broadcast audio according to the current navigation scene, wherein the target broadcast audio is obtained according to the current scene, the basic broadcast file and the voice broadcast strategy.

And S304, broadcasting the target broadcast audio.

However, as in the foregoing content part of the embodiment of the present invention, the length of the speech material specified in the speech broadcast policy may not be consistent with the length of the related content in the basic broadcast document corresponding to the speech material, and the audio obtained according to the speech material may also require more time than directly playing the related content of the basic broadcast document due to the slow speech speed during recording, and if the time allowed for broadcast is limited, it may be forced to discard important information. For another example, in an actual navigation process, a conflict may be generated between a position where broadcasting is required and broadcasting which is to be performed at present, for example, a left turn is required at present, but some less important audios are played, such as 'driving for a long distance, please take caution', and important information is lost under the situation.

Specifically, the acquiring a target broadcast audio according to a current navigation scene, as shown in fig. 6, includes:

s3031, the current navigation route is segmented into combinations of continuous road sections.

And S3032, obtaining the current remaining road section according to the segmentation result and the current positioning point.

It can be understood that, in the navigation scenario, the position of the current positioning point is updated in real time, and therefore, each time the current positioning point is updated, the step S3032 is triggered to be executed, and further the related subsequent steps are executed.

And S3033, obtaining a content set to be broadcasted according to the current residual road section, wherein the content set to be broadcasted comprises the report to be broadcasted and the priority corresponding to the report to be broadcasted.

Specifically, the content sets to be broadcasted can be divided into two types, namely a fixed broadcast content set and a non-fixed broadcast content set in a road segment, where the fixed broadcast content set in the road segment is a content set related to the current remaining road segment itself, such as "enter tunnel ahead"; the non-anchor cast content set may include a content set that is not related to the current remaining segment itself.

Specifically, each piece of content to be broadcasted can be managed in a broadcast queue form or a broadcast array form, the precedence position of the content to be broadcasted in the queue corresponds to the precedence relationship of the content to be broadcasted, and further, if the content to be broadcasted does not have the requirement for clear broadcast time, the content to be broadcasted can be set at any position in the queue.

And S3034, obtaining an audio sequence corresponding to the content set to be broadcasted according to a basic broadcasting file and a voice broadcasting strategy, wherein the audio sequence comprises audio and the priority corresponding to the audio.

Specifically, all the document contents to be expressed in the navigation route can be recorded in the basic broadcast document, the contents to be broadcasted belong to subsets of the basic broadcast document, and the voice broadcast strategy is used for guiding the strategy of replacing the related contents in the basic broadcast document by using customized voice materials, so that the audio sequence corresponding to the content set to be broadcasted can be obtained according to the basic broadcast document and the voice broadcast strategy. The priority of the audios in the audio sequence is uniquely determined according to the priority of the contents to be broadcasted in the contents to be broadcasted.

As shown in fig. 7, the vehicle drives from the road segment a to the road segment B, and the current remaining road segment L is obtained from the current positioning point in the road segment B. When the vehicle runs on the current remaining road section L, the contents to be broadcasted sequentially comprise 'forward congestion', 'forward is an accident multi-occurrence area', 'welcome to arrive at the Qingdao', 'forward speed limit 80', 'forward enter the electronic eye monitoring area' and 'forward left running' in the broadcasting queue, wherein the 'forward congestion', 'forward is the accident multi-occurrence area' and is the second priority, 'welcome to arrive at the Qingdao' is the third priority, 'forward speed limit 80' and 'forward enter the electronic eye monitoring area' are the first priority.

According to the setting of a voice broadcasting strategy, Linshiling voice materials are used in the road section A, and yellow Bohai voice materials are used after the road section A enters the road section B. The audio sequence corresponding to the content to be broadcasted is obtained by using a voice material of the yellow Bohai, the audio sequence is obtained by recording the voice of the yellow Bohai, and the content is sequentially ' congestion ahead, you can be in a hurry state ', ' accident multi-occurrence area ahead, please take care of the front ', ' welcome to the Qingdao ', the yellow Bohai accompanies with you all the way ', ' speed limit ahead 80, the current vehicle speed x ' and ' the front enter the monitoring area, and the vehicle driving is required to be standardized '. The front congestion, you can be dismissed, the front is an accident multi-occurrence area, you please pay attention to the fact that the upper priority is the second priority, the front speed limit 80, the current vehicle speed and the front entering monitoring area are the third priority, and the standard driving is the first priority.

S3035, predicting first running time of the vehicle in the current residual road section, and acquiring second running time required by playing of the audio sequence.

And S3036, extracting the target broadcast audio from the audio sequence according to the relation between the first running time and the second running time.

When the first running time is not less than the second running time, the whole content of the audio sequence can be allowed to be broadcasted, so that the target broadcast audio is the audio sequence. It goes without saying that the target broadcast audio in the embodiment of the present invention may be more than one audio.

When the first running time is less than the second running time, the extracting the target broadcast audio from the audio sequence as shown in fig. 8 includes:

and S30361, acquiring audio identification sequences according to the sequence of the priority from low to high.

For example, the contents of the audio sequence are "congestion ahead, you can be in a panic," accident-prone area "ahead," please be careful to be up, "" welcome to go to the Qingdao, "yellow Bohai accompanies you all the way," "front speed limit 80, current vehicle speed ×," front entering monitoring area, "please regulate driving", and the identifications thereof are A, B, C, D, E, respectively.

The resulting audio identification sequence should be D, E, A, B, C, ordered by its priority.

And S30362, acquiring the playing time corresponding to each audio identifier according to the audio identifier sequence.

S30363, determining a cut-off audio identification from the audio identification sequence.

In an example provided by the embodiment of the present invention, 5 pieces of content of the audio sequence cannot be played in the first runtime, the time for sequentially playing D, E, A corresponding to audio is less than the first runtime, and the time for sequentially playing D, E, A, B is greater than the first runtime, so B is the end audio identifier.

And S30364, obtaining a target audio identification sequence according to the cut-off audio identification, wherein the target audio identification sequence is a sequence formed by arranging audio identifications in the audio identification sequence in sequence before the cut-off audio identification.

Specifically, the target audio identification sequence is an audio identification sequence that simultaneously satisfies the requirements of playing audio according to priority and playing at most two items of content.

And S30365, extracting audio from the audio sequence according to the identification of the target audio identification sequence to form target broadcast audio.

As shown in fig. 7, D, E, A corresponding audio will be played. In a preferred embodiment of the present invention, the content to be broadcasted corresponding to the unretracted audio in the audio sequence may re-enter the content set to be broadcasted in the link that the anchor point is updated to trigger the execution of step S3032, so that there is still a chance to be broadcasted in the subsequent broadcasting process.
