Specific embodiment

To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with attached drawing to the application embodiment party Formula is described in further detail.

Fig. 1 is a kind of schematic diagram of the implementation environment of the phonetic navigation method provided according to an exemplary embodiment.Such as Fig. 1 Shown, which includes: mobile device 101 and server 102, and mobile device 101 can be led to server 102 Letter, to realize the Voice Navigation of mobile device.

As an example, mobile device 101 can be any one can with user by keyboard, touch tablet, touch screen, One or more modes such as remote controler, interactive voice or handwriting equipment carry out the electronic product of human-computer interaction, such as PC (Personal Digital Assistant, individual digital help by (Personal Computer, personal computer), mobile phone, PDA Hand), wearable device, tablet computer, vehicle-mounted computer etc..Server 102 can be a server, be also possible to be taken by more The server cluster or a cloud computing service center of business device composition.

It should be understood that above-mentioned mobile device 101 and server 102 are only for example, other are existing or from now on may The mobile device or server of appearance are such as applicable to the application, should also be included within the application protection scope, and herein with Way of reference is incorporated herein.

Fig. 2 is a kind of flow chart of the phonetic navigation method provided according to an exemplary embodiment, and this method is applied to move Dynamic equipment.Referring to fig. 2, this method comprises:

Step 201: obtaining at least two casting elements, each casting element includes at least one casting component and at least one Sequentially, at least two casting elements are used for the casting component by including on guidance path and currently for the casting of a casting component The induction point that the distance between position is less than reference distance is prompted.

In some embodiments, it when mobile device carries out Voice Navigation, can be obtained on guidance path from server The location information of the location information of each position, each induction point, and the casting member for being prompted each induction point Element.In this way, mobile device during navigation, can obtain navigation according to current moving direction since current location Multiple induction points on path, determine the distance between each induction point of current location and acquisition, and according to determining distance, The distance between current location is selected to be less than the induction point of reference distance from multiple induction points of acquisition.By the induction of selection The corresponding casting element of point is determined as at least two casting elements described above.

Under normal conditions, mobile device needs carry out Voice Navigation under moving condition, that is to say, mobile device is led Endurance has certain movement speed, and therefore, in order to carry out the prompt of induction point in time, mobile device can be in real time Obtain at least two casting elements.However, when mobile device movement speed is slower or mobile device because some reasons from When moving condition is switched to halted state, the mode for obtaining at least two casting elements in real time will cause the waste of some resources. In such a case, it is possible to the movement speed of mobile device be determined, if movement speed is less than threshold speed, then it represents that movement is set Standby current movement speed is slower, at this point it is possible to periodically obtain at least two casting elements.

Under normal conditions, there can be a certain distance between two neighboring induction point, therefore, can count on guidance path Distance is obtained by the minimum range in the distance of statistics divided by the movement speed of mobile device between per two adjacent induction points To the cycle length in the acquisition period of at least two casting elements.Alternatively, by the minimum range in the distance of statistics divided by above-mentioned Threshold speed obtains the cycle length in the acquisition period of at least two casting elements.Certainly, the acquisition of at least two casting elements The cycle length in period can also be arranged by other means, and the embodiment of the present application does not limit this.

In some embodiments, some factors are based on, an induction point can be prompted once, can also be carried out repeatedly Prompt.Illustratively, unessential induction point can be prompted once, and important induction point can be mentioned repeatedly Show.Alternatively, history is broken rules and regulations, rate and/or the lower induction point of yaw rate can be prompted once, history rate violating the regulations and/or yaw The higher induction point of rate can be prompted repeatedly.In this way, may include same lure in at least two casting elements obtained Lead a little corresponding one or more casting elements.Such as, it is assumed that it is less than reference with the distance between current location on guidance path The induction point of distance has 3, respectively induction point 1, induction point 2 and induction point 3.Induction point 2 is important, induces point 1 and lures Lead a little 3 inessential, at this point, 4 casting elements may be got, respectively the casting element of induction point 1, induction are put 2 and broadcast Report the casting element of element, the casting element of induction point 2 and induction point 3.It that is to say, wrapped at least two casting elements of acquisition Include the corresponding two casting elements of induction point 2.

In addition, breaking rules and regulations rate and/or the higher induction point of yaw rate about history, the induction point can not only be carried out multiple Prompt, can also give prominence to the key points crucial casting component in each prompt, illustratively, carry out to key casting component continuous more Secondary broadcasting.In this way, element is broadcasted other than including the casting sequence of at least one casting component and at least one casting component, Key casting component can also be marked.

It should be understood that above-mentioned threshold speed and reference distance can preset and solidify in a mobile device, when So, above-mentioned threshold speed and reference distance can also the setting when carrying out Voice Navigation can be set and in different situations Different numerical value.

It should be noted that the casting component in each casting element can be determined according to the type of induction point, for example, For turn to crossing for, this induction point casting element may include 5 casting components, respectively distance, position, turn To, auxiliary and lane, and casting sequence is followed successively by distance, position, steering, auxiliary, lane.Wherein, the interior of component is broadcasted for this 5 Appearance can be such that

Distance: * d in front of value=

Position: value=traffic light intersection

Turn to: value=turns right

Auxiliary: value=enters the road Guang Ze

Lane: value=please lean on rightmost side lanes

In above-mentioned casting component, * d is indicated apart from placeholder.

In some embodiments, the casting component in each casting element can also be anti-according to the type of induction point and navigation Feedforward information determines that navigation feedback information may include the history rate violating the regulations and yaw rate at induction point place.It that is to say, when history is disobeyed When chapter rate and/or higher yaw rate, the content of casting component can be refined.Continue by taking above-mentioned steering crossing as an example, this 5 The content of a casting component can be such that

Distance: * d in front of value=

Position: value=reaches traffic light intersection

Turn to: value=please turn right

Auxiliary: value=enters the road Guang Ze

Lane: value=please leans on rightmost side lanes in advance

Step 202: according at least two casting elements, generating at least two voice guidance messages.

One casting element is for prompting an induction point, therefore, get at least two casting elements it Afterwards, at least two voice guidance messages can be generated according at least two casting elements.In some embodiments, at least The first casting element in two casting elements, can broadcasting according at least one the casting component for including in the first casting element Report sequence generates voice guidance message, the first casting element according at least one the casting component for including in the first casting element For any casting element at least two casting elements.It, can also for other casting elements at least two casting elements To generate corresponding voice guidance message according to the method described above.Illustratively, for above-mentioned steering crossing, the voice guide of generation Information can be with are as follows: 300 meters of front, traffic light intersection are turned right, and into the road Guang Ze, please lean on rightmost side lanes.

For different users, the different voice guidance message of content intact degree can be generated, for example, when carrying out vehicle When Voice Navigation, for fresh driver, the situation on road may be familiar with, it is more complete that content can be generated in this way Whole voice guidance message, and for old driver, it may be familiar to the situation on road, it can be generated so interior Hold simpler voice guidance message.It therefore, can be according to user for the first casting element at least two casting elements Feature filters out part casting component from the first casting element.According to the casting sequence of the casting component filtered out, according to sieve The casting component selected generates voice guidance message.Illustratively, for above-mentioned steering crossing, for fresh driver, generation Voice guidance message can be with are as follows: 300 meters of front, traffic light intersection are turned right, and into the road Guang Ze, please lean on rightmost side lanes.Needle To old driver, the voice guidance message of generation can be with are as follows: 300 meters of front, traffic light intersection are turned right, and rightmost side lane row please be leaned on It sails.

Since different users corresponds to different user characteristics, according to different user characteristics, generate different languages If sound guidance information, different prompts can be carried out for different users, that is to say, which can pointedly carry out voice, leads Boat, and then user's viscosity can be further increased.

In some embodiments, user characteristics can be arranged by mobile device in user.Illustratively, user can touch The setting options in mobile device are sent out, at this point, mobile device can receive setting instruction, and show the setting page, the setting It include completely broadcasting option and simplifying casting option in the page.When what mobile device detected complete casting option chooses operation When, show to need to generate the more complete voice guidance message of content, at this point it is possible to which user characteristics are arranged for active user Completely to broadcast feature.When choosing operation of option of casting is simplified when mobile device detects, shows to need active user The more simple voice guidance message of content is generated, at this point it is possible to which it is to simplify casting feature that user characteristics, which are arranged,.

In further embodiments, user characteristics can be arranged by study historical navigation situation in mobile device.Example Property, mobile device can obtain the corresponding historical navigation frequency of the user account currently logged in from server, historical navigation Frequency refers to that historical navigation number accounts for the ratio of history trip number.If historical navigation frequency is greater than frequency threshold, show For active user, need to generate the more complete voice guidance message of content, at this point it is possible to which it is completely to broadcast that user characteristics, which are arranged, Report feature.If historical navigation frequency is not more than frequency threshold, show that active user is needed to generate content more simple Voice guidance message, at this point it is possible to be arranged user characteristics be simplify casting feature.The number for example, mobile device history is gone on a journey It is 1000 times, has in this 1000 times 900 times and all carried out Voice Navigation, that is to say, historical navigation number is 900, therefore, is gone through History navigation frequency is 0.9.Assuming that frequency threshold is 0.8, then may indicate that for active user, need to generate content more complete Whole voice guidance message, at this point it is possible to which it is complete casting feature that user characteristics, which are arranged,.

It should be understood that require to obtain some navigation datas from server when mobile device is navigated every time, and Mobile device can also send a notification message in each trip to server, in this way, server can determine mobile device Historical navigation number and history trip number, and then can determine historical navigation frequency.In addition, said frequencies threshold value can be preparatory Be arranged and solidify in a mobile device, certainly, said frequencies threshold value can also the setting when carrying out Voice Navigation, and different In the case of, different numerical value can be set.

In some other embodiment, mobile device can also be by determining whether the region being presently in is resident area User characteristics are arranged.Illustratively, mobile device can determine the region being presently in, if the region being presently in is not Resident area then shows to need to generate the more complete voice guidance message of content, at this point it is possible to be arranged for active user User characteristics are complete casting feature.If historical navigation frequency is not more than frequency threshold, show to need active user The more simple voice guidance message of content is generated, at this point it is possible to which it is to simplify casting feature that user characteristics, which are arranged,.For example, mobile The region that equipment is presently in is Tianjin, and the resident area of mobile device is Beijing, at this point it is possible to determine mobile device not normal In region, then may indicate that for active user, need to generate the more complete voice guidance message of content, at this point it is possible to It is complete casting feature that user characteristics, which are arranged,.

As an example, resident area can be arranged by mobile device in user, for example, user can trigger movement Setting options in equipment at this point, mobile device can receive setting instruction, and show the setting page, in the setting page Including resident area edit box.Mobile device can obtain the resident area of user setting from resident area edit box.Another In a kind of example, mobile device can also obtain the resident area of the user account currently logged in from server.For example, service Device can count the region of the user account historical navigation currently logged in and the historical navigation frequency in each region, and will go through The highest region of history navigation frequency is set as resident area.

Step 203: according to current location and current movement speed, when determining the broadcasting of at least two voice guidance messages Between.

Play time usually may include starting playing time and end playing time.And broadcasting when voice guidance message If putting opportunity difference, the play time of voice guidance message also can be different.Illustratively, a kind of broadcasting opportunity refers to that movement is set The standby broadcasting that voice guidance message is carried out when the distance between with induction point being first distance threshold value, another broadcasting opportunity refers to After voice guidance message broadcasting terminates, the distance between mobile device and induction point are second distance threshold value.Second distance threshold Value is generally less than first distance threshold value.

If the broadcasting opportunity of voice guidance message is different, according to current location and current movement speed, determine at least The mode of the play time of two voice guidance messages is also different.And the determination side of the play time of each voice guidance message Formula is identical, draws in order to make it easy to understand, any voice guidance message at least two voice guidance messages is known as the first voice Information is led, the corresponding induction point of the first voice guidance message is known as the first induction point, next to the first voice guidance message The method of determination of play time be introduced.

In some embodiments, for the first above-mentioned broadcasting opportunity, the broadcasting of the first voice guidance message can be determined Duration determines the distance between current location and the first induction point, by the distance referred to as first distance.By first distance and first The distance between distance threshold difference obtains first movement duration divided by current movement speed.It will increase by the first shifting current time Beginning playing time at the time of being obtained after dynamic duration as the first voice guidance message, by opening for the first voice guidance message Beginning playing time increases end playing time at the time of playing duration obtains later as the first voice guidance message.

For example, the playing duration of the first voice guidance message is 5 seconds, the distance between current location and the first induction point are 300 meters, i.e. first distance is 300 meters.Assuming that first distance threshold value is 150 meters, current movement speed is 15 meter per seconds, when current Carving is 9 points, then, by the distance between first distance and first distance threshold value difference divided by current movement speed, obtain the One is 10 seconds a length of when mobile.It will increase at current time at the time of first movement duration obtains later as the first voice guidance message Beginning playing time, at the time of being obtained after the beginning playing time of the first voice guidance message is increased playing duration as The end playing time of first voice guidance message.That is to say, the beginning playing time of the first voice guidance message be 9 points 0 minute 10 seconds, the end playing time of the first voice guidance message be 9 points 15 seconds 0 minute.

For above-mentioned second of broadcasting opportunity, it can determine the playing duration of the first voice guidance message, determine present bit The distance between first induction point is set, by the distance referred to as first distance.It will be between first distance and second distance threshold value Distance difference obtains the second mobile duration divided by current movement speed.It will increase by the second mobile duration current time to obtain later At the time of end playing time as the first voice guidance message, the end playing time of the first voice guidance message is subtracted Beginning playing time at the time of being obtained after playing duration as the first voice guidance message.

For example, the playing duration of the first voice guidance message is 5 seconds, the distance between current location and the first induction point are 300 meters, i.e. first distance is 300 meters.Assuming that second distance threshold value is 60 meters, current movement speed is 15 meter per seconds, current time Be 9 points, then, by the distance between first distance and second distance threshold value difference divided by current movement speed, obtain second It is 16 seconds a length of when mobile.Current time is increased at the time of the second mobile duration obtains later as the first voice guidance message Terminate playing time, the end playing time of the first voice guidance message is subtracted at the time of obtaining after playing duration as the The beginning playing time of one voice guidance message.That is to say, the beginning playing time of the first voice guidance message be 9 points 0 minute 11 Second, the end playing time of the first voice guidance message be 9 points 16 seconds 0 minute.

Step 204: if the play time of any two voice guidance message at least two voice guidance messages exists Overlapping, is adjusted any two voice guidance message, so that any two voice guidance message adjusted is broadcast Putting the time, there is no overlappings.

Since play time usually may include starting playing time and terminating playing time, that is to say, play time is One period therefore can be by the play time of any two voice guidance message at least two voice guidance messages It is compared, to determine the play time of any two voice guidance message with the presence or absence of overlapping.If any two language There is overlapping in the play time of sound guidance information, then just needing to be adjusted any two voice guidance message.

For example, at least two voice guidance message is respectively that voice guidance message 1, voice guidance message 2 and voice draw Lead information 3, the play time of voice guidance message 1 be 9 points 15 0: 10 seconds 0 minute to 9:, when the broadcasting of voice guidance message 2 Between for 9 points 20 0: 13 seconds 0 minute to 9:, the play time of voice guidance message 3 be 9 points 26 0: 19 seconds 0 minute to 9:.That , there is overlapping, voice guidance message 2 and voice guidance message in the play time of voice guidance message 1 and voice guidance message 2 There is also overlappings for 3 play time, at this time, it is necessary to all be adjusted to these three voice guidance messages, so that adjusted There is no overlappings for the play time of these three voice guidance messages.

In some embodiments, play time may include starting playing time and terminating playing time, to any two The operation that voice guidance message is adjusted can be with are as follows: when determining the overlapping of the play time of any two voice guidance message It is long.Duration is referred to if being overlapped duration and being less than or equal to, at least one voice guide in any two voice guidance message The beginning playing time of information is adjusted.

As an example, the beginning playing time and the first voice guidance message of the first voice guidance message can be determined Previous voice guidance message end playing time between first interval duration, determine the end of the second voice guidance message The second interval duration between the beginning playing time of the latter voice guidance message of playing time and the second voice guidance message, First voice guidance message is the voice guidance message for starting playing time morning in any two voice guidance message, the second voice Guidance information is the voice guidance message for starting playing time evening in any two voice guidance message.If the first interval duration It is all larger than or is equal to overlapping duration with the second interval duration, then the beginning playing time of the first voice guidance message is adjusted to the One moment, the first moment beginning playing time original earlier than the first voice guidance message, and with the first voice guidance message Starting the duration between playing time is overlapping duration.Alternatively, the beginning playing time of the second voice guidance message is adjusted to Second moment, the second moment are later than the original beginning playing time of the second voice guidance message, and with the second voice guidance message Duration between original beginning playing time is overlapping duration.If the first interval duration is greater than or equal to overlapping duration and the Two interval durations are less than overlapping duration, then the beginning playing time of the first voice guidance message are adjusted to for the first moment.If First interval duration is less than overlapping duration and the second interval duration is greater than or equal to overlapping duration, then by the second voice guidance message Beginning playing time be adjusted to for the second moment.If the first interval duration and the second interval duration are respectively less than and are overlapped duration, and First interval duration is spaced the sum of duration with second and is greater than or equal to Chong Die duration, then starts to broadcast by the first voice guidance message It puts and is adjusted to the third moment constantly, the beginning playing time of the second voice guidance message is adjusted to the 4th moment, the first adjustment The sum of duration and second adjustment duration are overlapping duration, and when the first adjustment at a length of third moment and the first voice guidance message are original Beginning playing time between duration, when second adjustment at a length of 4th moment and the second voice guidance message it is original start to broadcast Put the duration between the moment.If the first interval duration and the second interval duration are respectively less than and are overlapped duration, and the first interval duration The sum of duration is spaced with second and is less than Chong Die duration, then when the beginning playing time of the first voice guidance message being adjusted to the 5th It carves, the beginning playing time of the second voice guidance message was adjusted to for the 6th moment, the 5th moment believed earlier than the first voice guide Cease original beginning playing time, and between the beginning playing time of the first voice guidance message when a length of first interval when Long, the 6th moment was later than the original beginning playing time of the second voice guidance message, and original with the second voice guidance message Start playing time between when it is a length of second interval duration.But in this case, after adjusting play time, first The play time of voice guidance message and the second voice guidance message can also have overlapping, in this way, can be according to subsequent mode The content of at least one voice guidance message in the two voice guidance messages is adjusted.After adjustment mode can refer to Continuous content.

It should be noted that if there is no the previous voice guidance message of the first voice guidance message, it is possible to recognize It is greater than overlapping duration for the first interval duration.Similarly, if there is no the latter voice guidance message of the second voice guidance message, It is possible to think that the second interval duration is greater than overlapping duration.

For ease of description, two voice guidance messages that play time has overlapping are properly termed as one group of voice guide Information.In this way, there may be the multiple groups voice guidance message of play time overlapping in above-mentioned at least two voice guidance message, it is right In the multiple groups voice guidance message, can be adjusted in the manner described above.

Due to reference duration be usually arranged it is smaller, if overlapping duration be less than or equal to refer to duration, then, In the manner described above to the beginning playing time of at least one voice guidance message in any two voice guidance message into After row adjustment, for a user and unaware, nor the effect of Voice Navigation may be will affect.But if overlapping Duration, which is greater than, refers to duration, then user may perceive, and may also influence if adjusting in the manner described above The effect of Voice Navigation.In such a case, it is possible to be adjusted in other way to any two voice guidance message It is whole.

It as an example, can be in any two voice guidance message if overlapping duration, which is greater than, refers to duration The beginning playing time of at least one voice guidance message is adjusted, then, in any two voice guidance message The content of at least one voice guidance message is adjusted.As another example, if overlapping duration, which is greater than, refers to duration, to this The content of at least one voice guidance message in any two voice guidance message is adjusted.

In the case where being overlapped duration greater than with reference to duration, at least one language in any two voice guidance message After the beginning playing time of sound guidance information is adjusted, the play time of any two voice guidance message may be deposited also It is being overlapped, at this point it is possible to be adjusted to the content of at least one voice guidance message in any two voice guidance message It is whole.But in some cases, directly at least one voice guidance message in any two voice guidance message After appearance is adjusted, the play times of the two voice guidance messages may would not have overlapping, at this point it is possible to without into Row starts the adjustment of playing time.

In the case where being overlapped duration greater than with reference to duration, at least one language in any two voice guidance message The operation that the beginning playing time of sound guidance information is adjusted is similar with aforesaid way, the difference is that, if between first It is all larger than or is equal to overlapping duration every duration and the second interval duration, alternatively, the first interval duration is greater than or equal to overlapping duration And second interval duration be less than overlapping duration, alternatively, first interval duration be less than overlapping duration and second interval duration be greater than or Equal to overlapping duration, at this point, the duration of adjustment is with reference to duration.If the first interval duration and the second interval duration are respectively less than Be overlapped duration, and the first interval duration is greater than or equal to Chong Die duration with second interval the sum of duration, at this point, the duration adjusted it Be with reference to duration.But if the first interval duration and the second interval duration are respectively less than and are overlapped duration, and when the first interval It is long to be spaced the sum of duration less than Chong Die duration with second, at this time, it may be necessary to judge the sum of the first interval duration and second interval duration Whether it is greater than or equal to and refers to duration.If it is greater than or be equal to refer to duration, then, the sum of duration of adjustment be also reference when It is long, if no more than duration is referred to, the duration of adjustment is respectively the first interval duration and the second interval duration.

Under normal conditions, it is adjusted to the content of a voice guidance message in any two voice guidance message Afterwards, play time, which can be solved, has overlapping, at this point, at least one voice in any two voice guidance message The operation that the content of guidance information is adjusted can be with are as follows: a voice guide letter is selected from any two voice guidance message Breath.Using the voice guidance message selected as the first voice guidance message, from the corresponding casting element of the first voice guidance message In, filter out part casting component.According to the casting sequence of the casting component filtered out, again according to the casting component filtered out Generate the first voice guidance message.

However, in some cases, after adjusting a voice guidance message, can may also have play time and there is weight Folded problem, at this point, the first voice guidance message regenerated can also be determined according to current location and current movement speed Play time.Using non-selected voice guidance message as the second voice guidance message, if the first voice regenerated There is overlapping in the play time of guidance information and the play time of the second voice guidance message, corresponding from the second voice guidance message Casting element in, filter out part casting component.According to the casting sequence of the casting component filtered out, broadcast according to what is filtered out Report component regenerates the second voice guidance message.

The mode that casting component in part is filtered out from the corresponding casting element of the first voice guidance message, and from the second language The mode that casting component in part is filtered out in the corresponding casting element of sound guidance information is identical.Moreover, regenerating the first voice The mode of guidance information is identical as the mode for regenerating the second voice guidance message, and regenerates the first voice guidance message Identical as the step 202 generation mode of voice guidance message with the mode for regenerating voice guidance message, details are not described herein again. Next, the mode of screen fraction casting component is introduced by taking the first voice guidance message as an example.

In addition to including that at least one broadcasts component and the casting sequence of at least one casting component in each casting element Except, it can also include the priority of at least one casting component.At this point, from the corresponding casting element of the first voice guidance message In, the operation for filtering out part casting component can be with are as follows: from the corresponding casting element of the first voice guidance message, filters out excellent First grade is greater than the casting component with reference to priority.Alternatively, being filtered out excellent from the corresponding casting element of the first voice guidance message First grade is the casting component of highest priority, and highest priority refers to that corresponding casting component cannot be deleted.

For example, the casting element of this induction point may include 5 casting components, respectively for turning to for crossing Distance, position, steering, auxiliary and lane, and casting sequence is followed successively by distance, position, steering, auxiliary, lane, but also including The priority of each casting component:

Distance: * d, level=max in front of value=

Position: value=traffic light intersection, level=8

Turn to: value=turns right, level=max

Auxiliary: value=enters the road Guang Ze, level=5

Lane: value=please depend on rightmost side lanes, level=7

In above-mentioned casting component, 8,5,7 be the priority of these casting components of position, auxiliary and lane, max respectively Expression cannot delete, and that is to say, max indicates highest priority.

Under normal conditions, the content of the casting component filtered out according to reference priority will be more than sieves according to highest priority Therefore the content for the casting component selected first can screen casting component according to reference priority, then determination regenerates The play time of two voice guidance messages is with the presence or absence of overlapping, if nonoverlapping, in this manner it is ensured that two voices draw The content for leading information is all more complete.It, can be by the first voice guidance message according to reference to preferential if there is also if overlapping Grade screening, the second voice guidance message is screened according to highest priority, alternatively, the first voice guidance message is excellent according to highest Second voice guidance message is screened according to reference priority, then determines two voice guides regenerated by first grade screening The play time of information is with the presence or absence of overlapping, if nonoverlapping, in this manner it is ensured that one of voice guidance message Content is more complete.But if there is also if overlapping, that just needs two voice guidance messages are preferential all in accordance with highest Grade is screened, in this way, can guarantee that overlapping is not present in the play time of two voice guidance messages, moreover it is possible to play Voice Navigation Effect.

It should be noted that aforesaid way is only a kind of example, voice guide can also be adjusted in other way The content of information.For example, the minimum casting component of priority in the first voice guidance message can first be screened out, according to screening The casting sequence of remaining casting component afterwards, regenerates the first voice guidance message according to casting component remaining after screening. According to current location and current movement speed, the play time of the first voice guidance message regenerated is determined.If giving birth to again At the first voice guidance message play time and the second voice guidance message play time exist overlapping, then continuing to sieve The casting component that priority is minimum in the first voice guidance message regenerated is fallen in choosing, repeats above-mentioned circulation, until giving birth to again At the first voice guidance message play time and the play time of the second voice guidance message there is no until Chong Die, or Person, the play time of the first voice guidance message regenerated and the play time of the second voice guidance message there are Chong Die, But until only existing the casting component of highest priority in the first voice guidance message regenerated.Feelings this for the latter Condition, since the play time of the first voice guidance message regenerated also exists with the play time of the second voice guidance message Overlapping, therefore, can according to the method described above screen the casting component in the second voice guidance message, until two languages Until overlapping is not present in the play time of sound guidance information or there is overlapping in the play time of two voice guidance messages, but Until being the casting component for only existing highest priority in the second voice guidance message regenerated.

For another example, the minimum casting component of priority in the first voice guidance message can be first screened out, according to screening The casting sequence of remaining casting component afterwards, regenerates the first voice guidance message according to casting component remaining after screening. According to current location and current movement speed, the play time of the first voice guidance message regenerated is determined.If giving birth to again At the first voice guidance message play time and the second voice guidance message play time exist overlapping, then can sieve The casting component that priority is minimum in the second voice guidance message is fallen in choosing, and the casting according to casting component remaining after screening is suitable Sequence regenerates the second voice guidance message according to casting component remaining after screening.According to current location and current mobile speed Degree determines the play time of the second voice guidance message regenerated.If the first voice guidance message regenerated is broadcast There is overlapping in the play time for the second voice guidance message putting the time and regenerating, it is possible to repeat above-mentioned circulation, directly To the play time and the play time of the second voice guidance message regenerated of the first voice guidance message regenerated There is no until overlapping, alternatively, the play time of the first voice guidance message regenerated and the second voice guidance message There is overlapping in play time, but in the first voice guidance message regenerated and the second voice guidance message regenerated Until the casting component for all only existing highest priority.

It should be noted that being all first to screen the casting group in the first voice guidance message in above-mentioned two situations Part is illustrated for the casting component in the second voice guidance message of screening afterwards.Wherein, the first voice guidance message can be Any voice guidance message in two voice guidance messages, the second voice guidance message are another in two voice guidance messages One voice guidance message.Certainly, the first voice guidance message may be the language that priority is low in two voice guidance messages Sound guidance information, the second voice guidance message are the voice guidance message that priority is high in two voice guidance messages, the application Embodiment does not limit this.

Under normal conditions, after being adjusted according to the method described above, there would not be two that play time has overlapping Voice guidance message, still, after adjusting according to the method described above, if there is also conflict is played, at this point it is possible to abandon One lower voice guidance message of priority.Wherein, mobile device from server obtain guidance path on each induction When the casting element of point, the priority of each casting element can also be obtained, since voice guidance message is by broadcasting element It generates, therefore, the priority for broadcasting element that is to say the priority of voice guidance message.

In addition to the beginning playing time at least one voice guidance message in any two voice guidance message carries out Except adjustment, in further embodiments, directly at least one voice in any two voice guidance message can also be drawn The content for leading information is adjusted.Wherein, at least one voice guidance message in any two voice guidance message Hold the mode being adjusted having already described above, repeat no more at this time.

It should be noted that if only existing one group of play time has overlapping two at least two voice guidance messages A voice guidance message, at this point it is possible to be adjusted according to the method described above.If at least two voice guidance messages, there are two There are two voice guidance messages of overlapping in group or play time more than two, at this point it is possible to which determining between any two groups is It is no to there is overlapping, if be not overlapped, it is possible to adjust each group according to the method described above.If there is overlapping, then just needing One group is first adjusted, then, according to the play time of that group voice guidance message adjusted, then next group is adjusted, to protect Overlapping is all not present in the play time for demonstrate,proving any two voice guidance message adjusted.

In addition, this at least two voice guide can be believed after step 202 generates at least two voice guidance messages Casting queue is added in breath, and is arranged according to the sequence of casting moment from morning to night is started.In this case, step 204 It can directly judge that the play time for broadcasting two voice guidance messages adjacent in queue whether there is overlapping, and not have to judgement The play time of any two voice guidance message can save the resource of a part with the presence or absence of overlapping, improve Voice Navigation Efficiency.Moreover, in this case, if there are two groups or play time more than two to deposit at least two voice guidance messages In two voice guidance messages of overlapping, it is possible to determine whether there is adjacent two groups, if it does not, can be by Each group is adjusted according to the above method.If it is present, previous group can first be adjusted, then according to previous group language adjusted The play time of sound guidance information, then later group is adjusted, to guarantee the broadcasting of any two voice guidance message adjusted Overlapping is all not present in time.

Step 205: being played out according to the play time of voice guidance message adjusted, to realize Voice Navigation.

After being adjusted according to the method described above, the play time of at least two voice guidance message adjusted is not deposited It is being overlapped, at this point it is possible to which the play time of voice guidance message adjusted plays out, to realize Voice Navigation.

Due at least two casting elements be used for by the casting component that includes on guidance path between current location Distance be less than the induction point of reference distance and prompted, if being less than the induction of reference distance with the distance between current location If point includes two or more, in order to avoid play time has overlapping and abandons a voice guidance message, lead The problem of causing some induction point not to be prompted, mobile device can be dynamically generated according at least two casting elements locally Or adjustment voice guidance message, so that there is no overlappings for the play time of any two voice guidance message adjusted.This Sample still can play the corresponding voice guidance message of at least two casting elements, play to two or more inductions The effect that is prompted of point, and this processing mode can neatly adjust voice guidance message start to broadcast the time or Content, and then can guarantee that the flexibility of navigation system is higher.

Fig. 3 is a kind of flow chart of the phonetic navigation method provided according to an exemplary embodiment, and this method is applied to move Dynamic equipment.Referring to Fig. 3, this method comprises:

Step 301: obtaining at least two groups voice guidance message, every group of voice guidance message includes that content intact degree is different At least one voice guidance message, at least two groups voice guidance message be used for on guidance path the distance between with current location Induction point less than reference distance is prompted.

In some embodiments, mobile device can determine between each induction point on current location and guidance path Distance, and according to determining distance, select the distance between current location to be less than the induction of reference distance from guidance path Point.Later, the corresponding voice guidance message of induction point that selection can be obtained from server, is drawn with obtaining at least two groups voice Lead information.

It is similar with step 201, at least two groups voice guidance message can be obtained in real time in step 301, it can also week At least two groups voice guidance message is obtained to phase property, and the cycle length in the acquisition period of at least two groups voice guidance message is really Determining mode can be identical as the mode in step 201.Moreover, an induction point can be prompted once, can also carry out more Secondary prompt.It therefore, may include that the corresponding one or more groups of voices of same induction point draw at least two groups voice guidance message Lead information.

Based on foregoing description, mobile device needs to obtain at least two groups voice guidance message from server, therefore, service Device needs to generate one group of voice guidance message for each induction point in advance, and may include content in this group of voice guidance message At least one different voice guidance message of integrity degree.

In some embodiments, server can first generate the most complete voice guidance message of content, that is to say, press According to the casting sequence at least one the casting component for including in the corresponding casting element of induction point, include according to the casting element At least one casting component generates a voice guidance message.Then, server can also be broadcast according to a variety of screening modes from this Casting component in part is filtered out in report element, according to the casting sequence of the casting component filtered out, according to the casting group filtered out Part generates multiple voice guidance messages.

It should be noted that a variety of screening modes can be identical as the screen fraction casting mode of component in step 204, That is, filtering out priority is greater than the casting component for referring to priority.Alternatively, filtering out the casting group that priority is highest priority Part.Or the casting component that priority is minimum in casting element is only screened out every time, and retain remaining casting group Part.

Distance: * d, level=max in front of value=

Position: value=traffic light intersection, level=8

Turn to: value=turns right, level=max

Auxiliary: value=enters the road Guang Ze, level=5

Lane: value=please depend on rightmost side lanes, level=7

If being screened in the way of only screening out a casting component every time, a variety of sieves may be obtained Select result.For example, the selection result obtained after screening is respectively as follows:, [distance, position, steering, lane], [distance, turns position To], [distance, turn to], [distance turns to, lane], [distance, position, steering, auxiliary], [distance, turn to, assist] etc..

Step 302: according to current location and current movement speed, determining each voice that every group of voice guidance message includes The play time of guidance information.

According to current location and current movement speed, each voice guidance message that every group of voice guidance message includes is determined Play time mode, in step 203 determine at least two voice guidance messages in each voice guidance message broadcasting The mode of time is identical, and details are not described herein again.

Step 303: according to the play time for each voice guidance message that every group of voice guidance message includes, from least two A voice guidance message is selected respectively in group voice guidance message, to obtain at least two voice guidance messages, at least two There is no overlappings for the play time of voice guidance message.

In some embodiments, the playing sequence of at least two groups voice guidance message can be first determined, then, according to broadcasting Sequence is put forward, a voice guidance message is selected from at least two groups voice guidance message, and guarantees to draw from two adjacent groups voice The play time of two voice guidance messages selected in information is led there is no being overlapped, in this way, at least two voices can be obtained Guidance information.

It include 3 voice guidance messages in first group of voice guidance message for example, getting 3 groups of voice guidance messages, point Not Wei voice guidance message 11, voice guidance message 12, voice guidance message 13, and when the broadcasting of this 3 voice guidance messages Between be respectively 9 points of 10 seconds 0 minute -9 points 0 minute and 15 seconds, 9 points of 8 seconds 0 minute -9 points 0 minute and 12 seconds, 9 points 12 seconds 0 minute -9 points 0 minute and 15 seconds.Second Include 2 voice guidance messages in group voice guidance message, respectively voice guidance message 21, voice guidance message 22, and this 2 The play time of a voice guidance message is respectively 9 points of 14 seconds 0 minute -9 points 0 minute and 20 seconds, 9 points 16 seconds 0 minute -9 points 0 minute and 21 seconds.The Including 2 voice guidance messages, respectively voice guidance message 31, voice guidance message 32 in three groups of voice guidance messages, and The play time of this 2 voice guidance messages is respectively 9 points of 18 seconds 0 minute -9 points 0 minute and 25 seconds, 9 points 22 seconds 0 minute -9 points 0 minute and 26 seconds. At this point, the voice guidance message selected from this three groups of voice guidance messages are as follows: voice guidance message 11, voice guidance message 22 and voice guidance message 32.Or are as follows: voice guidance message 12, voice guidance message 21 and voice guidance message 32.And or Person is voice guidance message 13, voice guidance message 22 and voice guidance message 32.

For different users, voice guidance message that can be different with broadcasting content integrity degree, for example, when carrying out vehicle When Voice Navigation, for fresh driver, the situation on road may be familiar with, it in this way can be more complete with broadcasting content Whole voice guidance message, and for old driver, it may be familiar to the situation on road, it can play so interior Hold simpler voice guidance message.Therefore, the broadcasting for each voice guidance message for including according to every group of voice guidance message Time selects the operation of a voice guidance message can be with are as follows: according to every group of language respectively from least two groups voice guidance message The play time and user characteristics for each voice guidance message that sound guidance information includes, from least two groups voice guidance message In, a voice guidance message is selected respectively.

As an example, when the broadcasting for each voice guidance message that can first include according to every group of voice guidance message Between, from least two groups voice guidance message, a voice guidance message is selected respectively.Since the result selected may include It is a variety of, at this point it is possible to the highest a kind of result of matching degree from this variety of result, between selection and user characteristics.Some In embodiment, the integrity degree of every kind of result can be determined, if user characteristics are complete casting feature, it is possible to which this is more A kind of highest result of integrity degree is determined as a kind of highest result of the matching degree between user characteristics in kind of result.If with Family feature is to simplify casting feature, it is possible to which a kind of minimum result of integrity degree in a variety of results is determined as and user The highest a kind of result of matching degree between feature.

As an example, a kind of integrity degree of result can be each voice guidance message for including in this result The sum of integrity degree.In some embodiments, the casting component that the integrity degree of a voice guidance message can include according to it Quantity determines.For example, determining in one group of voice guidance message belonging to this voice guidance message content most complete one The quantity for the casting component that voice guidance message includes, then removes the quantity for the casting component that this voice guidance message includes With the quantity for the casting component that the most complete voice guidance message of content includes, the complete of this voice guidance message is obtained Degree.In further embodiments, the weight for the casting component that the integrity degree of a voice guidance message can include according to it is come It determines.For example, the sum of the weight of each casting component in this voice guidance message can be determined, by the sum of the weight divided by Each casting in one group of voice guidance message belonging to this voice guidance message in the most complete voice guidance message of content The sum of weight of component obtains the integrity degree of this voice guidance message.Wherein, content is most complete in one group of voice guidance message Voice guidance message in the sum of the weight of each casting component be usually 1.

By taking the steering crossing in step 301 as an example, the corresponding highest voice guide of content intact degree in crossing is turned to The quantity for the casting component that information includes is 5, it is assumed that the quantity for the casting component that this current voice guidance message includes is 3, So, the integrity degree of this voice guidance message is 60%.Alternatively, turning to the corresponding highest language of content intact degree in crossing The sum of weight of each casting component in sound guidance information is 1, it is assumed that this current voice guidance message includes 2 components, Weight is respectively 0.5 and 0.3, then, the integrity degree of this voice guidance message is 80%.

Step 304: being played out according to the play time of at least two voice guidance messages, to realize Voice Navigation.

This step is identical as the mode of step 205, and details are not described herein again.

Since at least two groups voice guidance message is used to be less than reference with the distance between current location on guidance path The induction point of distance is prompted, and every group of voice guidance message includes different at least one voice guide letter of content intact degree Breath, in content integrity degree difference, play time also can be different, and therefore, can include according to every group of voice guidance message be every The play time of a voice guidance message selects a voice guidance message respectively from least two groups voice guidance message, from And guarantees the play time of at least two voice guidance messages obtained after selection and overlapping is not present.This way it is possible to avoid broadcasting The problem of time is put in the presence of overlapping and abandons a voice guidance message, some induction point is caused not to be prompted, and also act as To the effects that two or more induction points are prompted, and this processing mode can neatly select content complete The different voice guidance message of whole degree, and then can guarantee that the flexibility of navigation system is higher.
