Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments and specific features of the embodiments of the present invention are detailed descriptions of technical solutions of the embodiments of the present invention, and are not limited to technical solutions of the present invention, and the technical features of the embodiments and the embodiments of the present invention may be combined with each other without conflict.
The active dialog initiating method based on the user identity of the present invention is explained below, referring to fig. 1, the method includes the following steps:
step 101, identifying a user identity, and determining an active dialog trigger set corresponding to the user identity, wherein the active dialog trigger set comprises at least one active dialog trigger rule; each active dialog triggering rule comprises at least one triggering condition;
step 102, judging whether at least one trigger condition included in the at least one active dialog trigger rule in the active dialog trigger set corresponding to the user identity is satisfied, and determining whether to initiate an active dialog based on a judgment result;
step 103, if the active dialogue is determined to be initiated, generating a first voice and initiating the dialogue.
Preferably, the executing subject of the method of the present invention may be a vehicle-mounted system, such as a vehicle-mounted device, a vehicle-mounted navigation system, a vehicle-mounted entertainment system, and the like, and the method of the present invention is mainly described below by taking the vehicle-mounted system as an example, but the executing subject of the method of the present invention is not limited thereto.
Preferably, in step 101, the user identity is identified according to one or more of biometric identification methods, such as face identification, voiceprint identification, fingerprint identification, iris identification, and the like. In addition, other ways can be adopted to identify the user, for example, the corresponding relation between the user identity and the mobile phone MAC code is stored in the vehicle-mounted system, and after the user enters the vehicle, the mobile phone is automatically connected with the vehicle-mounted system, so that the vehicle-mounted system can read the MAC code of the mobile phone and further identify the user identity. In other embodiments, for example for a home vehicle, the correspondence of the user identity to their weight and/or body type may be stored in an on-board system, such that upon entry of the user into the vehicle, the user identity is identified based on the weight and/or body type. The above identification is only exemplary and should not be construed as limiting the invention.
Preferably, the vehicle-mounted system stores a corresponding relationship between the user identity and the active dialog trigger scenario set, for example, the user a corresponds to the active dialog trigger set 1, and the user B corresponds to the active dialog trigger set 2. Referring to tables 1 and 2, the active dialog trigger set 1 and the active dialog trigger set 2 may have different active dialog topics for the same trigger condition, such as a user getting on a car, and the active dialog trigger set 1 and the active dialog trigger set 2 may have different trigger conditions and trigger condition numbers for the same active dialog topic, such as turning on an air conditioner. The active dialog trigger set 1 may also have active dialog trigger conditions that the active dialog trigger set 2 does not have. The active dialog triggering rules shown in tables 1 and 2 are merely examples illustrating the method of the present invention and should not be construed as limiting the present invention.
Preferably, each active dialog triggering rule further includes an active dialog topic.
Preferably, each active dialog triggering rule further comprises at least one slot.
Table 1 active dialog trigger set 1 corresponding to user a
Table 2 active dialog trigger set 2 corresponding to user B
Preferably, step 102 specifically includes: judging whether at least one trigger condition included by the at least one active dialog trigger rule in the active dialog trigger set corresponding to the user identity is met, and if all the at least one trigger condition is met, determining to initiate active dialog; determining not to initiate an active dialog if one or more of the at least one trigger condition is not satisfied.
Preferably, step 102 specifically includes: judging whether at least one trigger condition included by the at least one active dialogue trigger rule in the active dialogue trigger set corresponding to the user identity is met, if all the at least one trigger condition is met, further judging whether the number of times of initiating active dialogue in a preset time length is greater than a preset threshold value, and if the number of times of initiating active dialogue is greater than the preset threshold value, determining not to initiate active dialogue; if the value is less than or equal to the preset threshold value, determining to initiate active dialogue; determining not to initiate an active dialog if one or more of the at least one trigger condition is not satisfied.
Preferably, each active dialog trigger rule has a corresponding priority, and the priorities may also be stored together in the active dialog trigger set. For example, in the active dialog trigger set 2, the priority of the active dialog trigger rule 2 is 3, the priority of the active dialog trigger rule 3 is 4, and the priority of the active dialog trigger rule 5 is 2. The setting of the priority can be determined according to the importance degree of the active dialog triggering rule, the influence degree of the active dialog content of the active dialog triggering rule on the user, the personal preference of the user and other factors. The factors considered above in determining the priority of the active dialog triggering rules are merely examples and should not be construed as limiting the invention.
Preferably, in step 102, specifically, it is determined whether at least one trigger condition included in the at least one active dialog trigger rule in the active dialog trigger set corresponding to the user identity is satisfied, if all the at least one trigger condition is satisfied, a current active dialog level is further determined, a priority condition corresponding to the current active dialog level is determined, it is determined whether the priority of the active dialog trigger rule that all the at least one trigger condition is satisfied satisfies the priority condition, if the priority condition is satisfied, it is determined that an active dialog is initiated, and if the priority condition is not satisfied, it is determined that an active dialog is not initiated; determining not to initiate an active dialog if one or more of the at least one trigger condition is not satisfied.
The current active dialogue level represents the current degree suitable for active dialogue, and the corresponding relation between the active dialogue level and the priority condition can be set individually by the user or can adopt a system default value. When the degree suitable for active dialogue is low, only the first voice generated by the active dialogue trigger rule with high priority is allowed to be played.
For example, when the user drives the car alone and does not talk, the current active dialog level is 4, the priority condition corresponding to the current active dialog level is less than or equal to priority 4, which means that the first voice generated by the active dialog trigger rule with priority less than or equal to 4 is allowed to be played currently, if all the trigger conditions of the active dialog trigger rule 3 of the active dialog trigger set 2 of the user B are satisfied, and the priority is 4, the priority condition is satisfied, and thus, it is determined that the active dialog is initiated; and when the user is in a call or chats with other passengers, the current active dialog level is 2, the priority condition corresponding to the current active dialog level 2 is less than or equal to the priority 2, and the meaning is that only the first voice generated by the active dialog trigger rule with the priority less than or equal to 2 is allowed to be played currently, if the trigger conditions of the active dialog trigger rule 3 of the active dialog trigger set 2 of the user B are all satisfied, but the priority is 4, the trigger conditions are not satisfied, so that the active dialog is determined not to be initiated, and if the trigger conditions of the active dialog trigger rule 5 of the active dialog trigger set 2 of the user B are all satisfied, and the priority is 2, the trigger conditions are satisfied, so that the active dialog is determined to be initiated.
In the above example, the smaller the priority value is, the higher the priority is, for example, the priority of 2 is higher than the priority of 4. In another implementation, the larger the priority value, the higher the priority, e.g., 4 is higher than 2. Depending on the particular implementation, and should not be construed as limiting the invention.
Preferably, step 102 is specifically to determine whether at least one trigger condition included in the at least one active dialog trigger rule in the active dialog trigger set corresponding to the user identity is satisfied, if all of the at least one trigger condition is met, further determining a current active dialog level, and determining a priority condition corresponding to a current active dialog level, performing a first determination whether the priority of the active dialog trigger rule that all of the at least one trigger condition satisfies the priority condition, and executing a second judgment whether the number of times of active session initiation is less than or equal to a preset threshold value within a preset time period, and determining to initiate an active session when both the first judgment and the second judgment result are yes, if the first judgment result and the second judgment result are both negative or one of the first judgment result and the second judgment result is negative, determining not to initiate active conversation; determining not to initiate an active dialog if one or more of the at least one trigger condition is not satisfied.
Preferably, in step 102, it is determined whether at least one trigger condition included in the at least one active dialog trigger rule in the active dialog trigger set corresponding to the user identity is satisfied, specifically, a value of a parameter associated with each trigger condition in the at least one trigger condition is obtained, and it is determined whether the trigger condition is satisfied based on the value of the parameter and the trigger condition. The values of the parameters can be acquired through interaction with a server, can be acquired through the vehicle-mounted system, and can be acquired through various sensors/devices connected with the vehicle-mounted system. According to different trigger conditions, the parameters may include: environmental information, vehicle status, user status, etc. The environment information may include road condition information, weather information, and the like, the vehicle state may include battery power, fuel tank capacity, vehicle driving speed, vehicle tire pressure, temperature in the vehicle, and the like, and the user state may include a user emotional state, a user physiological state, a user driving state, and the like. For example, in table 1, the parameter associated with the trigger condition 1 of the active session trigger rule 2 is road condition information, the vehicle-mounted system acquires the road condition information by communicating with the server, the parameter associated with the trigger condition 2 of the active session trigger rule 2 is a user emotion state, and can be obtained by acquiring a user facial image and analyzing the expression of the user facial image through a camera, the parameter associated with the trigger condition 1 of the active session trigger rule 3 is an in-vehicle temperature, and the vehicle-mounted system obtains a value of the in-vehicle temperature through an in-vehicle temperature sensor.
Preferably, step 102 is performed periodically with a preset periodicity. The preset period can be set by a user or can adopt a system default value. The preset period may have a correspondence with the user identity. For example, the preset period corresponding to the user a may be 5 minutes, and the preset period corresponding to the user B may be 6 minutes.
Preferably, a first voice is generated and a dialog is initiated in step 103, specifically, the first voice is generated according to an active dialog theme included in the active dialog trigger rule, and the first voice is reported to a user.
Preferably, a first voice is generated and a dialog is initiated in step 103, specifically, the first voice is generated according to an active dialog theme and at least one slot included in the active dialog trigger rule, and the first voice is broadcasted to a user.
Preferably, the at least one slot has a slot filling rule corresponding thereto, and/or the at least one slot has a default value.
Preferably, the step 103 is specifically to fill the at least one slot according to a corresponding slot filling rule, and generate a first voice according to an active dialog theme included in the active dialog trigger rule and the at least one filled slot; and/or generating a first voice according to the active dialogue theme and the default value of at least one slot position included in the active dialogue triggering rule.
Preferably, the at least one slot is filled according to a corresponding slot filling rule, specifically, for each slot of the at least one slot, a value of a parameter related to the slot filling rule corresponding to the slot is obtained, and the slot is filled according to the obtained value and the slot filling rule.
Preferably, in step 103, when the triggering conditions of the multiple active dialog triggering rules are simultaneously satisfied, multiple first voices are generated based on the multiple active dialog triggering rules, and the order of broadcasting the first voices to the user is determined according to the priority of the active dialog triggering rules.
Preferably, the triggering conditions of the active dialog triggering rules are simultaneously satisfied, where the triggering conditions of the active dialog triggering rules are the same, and the triggering conditions of the active dialog triggering rules are simultaneously satisfied, for example, the triggering conditions of the active dialog triggering rules 2 and 5 in table 2 are all bad road conditions, if the priority of the active dialog triggering rule 2 is 3, the priority of the active dialog triggering rule 5 is 2, if the priority value is smaller, the priority is higher, the first voice generated based on the active dialog triggering rule 5 should be played to the user first, and then the first voice generated based on the active dialog triggering rule 2 should be played to the user.
Preferably, the triggering conditions of the active dialog trigger rules are simultaneously satisfied, or may be simultaneously satisfied although the triggering conditions of the active dialog trigger rules are different, for example, the triggering condition "the in-vehicle temperature is higher than 24 degrees" of the active dialog trigger rule 4 in table 2 and the triggering condition "the road condition is not good" of the active dialog trigger rule 5 may be simultaneously satisfied, assuming that the priority of the active dialog trigger rule 5 is 2 and the priority of the active dialog trigger rule 4 is 3, if the smaller the value of the priority is, the higher the priority is, the first voice generated based on the active dialog trigger rule 5 should be played to the user first, and then the first voice generated based on the active dialog trigger rule 4 should be played to the user.
Preferably, the active dialog trigger set is updated according to the historical dialog records of the user and the vehicle-mounted system, and the updating can be adding, deleting and modifying the active dialog trigger rules in the active dialog trigger set. The historical dialogue records of the user and the vehicle-mounted system can be dialogue actively initiated by the user or dialogue actively initiated by the vehicle-mounted system.
An active dialog trigger rule is added, topics which are interesting to a user can be determined according to historical dialog records, and the active dialog trigger rule is added based on the topics, for example, a user A actively initiates a dialog of what scenic spots on the left of a road are based on a small teak, after a vehicle-mounted system answers the user, the user A can be considered to be interested in scenic spot POIs, an active dialog trigger rule is added in an active dialog trigger scene set corresponding to the user A, a trigger condition 1 is set to pass through the scenic spot POIs, active dialog contents are set to introduce the scenic spot POIs, and scenic spot name slots are added.
Deleting the active dialog triggering rule may be: the method comprises the steps of periodically analyzing historical conversation records to obtain active conversations rejected by users or with low conversation willingness, further obtaining active conversation trigger rules for triggering each active conversation, counting the conversation times corresponding to each active conversation trigger rule rejected by users or with low conversation willingness, and deleting the corresponding active conversation trigger rules based on the conversation times, wherein the active conversation trigger rules comprise one or more active conversation trigger rules with the largest conversation times rejected by users or with low conversation willingness, and the active conversation trigger rules comprise one or more active conversation trigger rules with the conversation times larger than a threshold value rejected by users or with low conversation willingness.
The active dialog triggering rules are modified, which can be: and adding, deleting or modifying the trigger conditions, the active conversation subjects and the slots in the active conversation trigger rules according to the historical conversation records. For example, for the user a, if the user actively requests to play music many times under the condition of poor road conditions but stable emotion, the trigger condition 2 of the active dialog trigger rule 2 of the active dialog trigger set 1, i.e., "user's emotional impatience" is deleted.
Preferably, an active dialog trigger set setting interface is provided to the user, through which the user can set the active dialog trigger rules individually.
Preferably, one or more active dialog trigger rules in the active dialog trigger set may also be synchronized between different users. In response to a request of a user, the vehicle-mounted system adds one or more active dialog trigger rules in an active dialog trigger set of other users to an active dialog trigger set corresponding to the user, where the request carries an indication of the active dialog trigger rule that the user wants to add, for example, which active dialog trigger rule of which user.
Preferably, after receiving the request, the vehicle-mounted system may send an inquiry message to the other user, and after the other user agrees, add the active dialog trigger rule requested to be added by the user to the active dialog trigger set corresponding to the user.
The process of the present invention is illustrated below with reference to specific examples.
The first embodiment is as follows:
if the user identity is identified as the user a in step 101, it is determined that the active dialog trigger set corresponding to the user identity is the active dialog trigger set 1. When a user a gets on the bus, a triggering condition 1 of an active dialog triggering rule 1 in an active dialog triggering set 1 is met, and at this time, it is determined that an active dialog needs to be initiated.
If the user identity is identified as the user B in step 101, it is determined that the active dialog trigger set corresponding to the user identity is the active dialog trigger set 2. When the user B gets on the vehicle, the trigger condition 1 of the active dialog trigger rule 1 in the active dialog trigger set 2 is satisfied, and at this time, it is determined that the active dialog needs to be initiated.
Example two:
if the user identity is identified as the user a in step 101, it is determined that the active dialog trigger set corresponding to the user identity is the active dialog trigger set 1. When a user a gets on the vehicle, a triggering condition 1 of an active dialog triggering rule 1 in an active dialog triggering set 1 is satisfied, and at this time, it is determined that an active dialog needs to be initiated, in this embodiment, a first voice is generated according to an active dialog theme and at least one slot, and a dialog is initiated, where the specific process is as follows:
filling the slot and the zamei slot: the parameter related to the slot filling rule of the slot in the time period is the user boarding time, and the slot filling rule is specifically that if the user boarding time is from 0 to 12, the slot in the time period is filled to morning, if the user boarding time is from 12 to 14, the slot in the time period is filled to noon, if the user boarding time is from 14 to 18, the slot in the time period is filled to afternoon, if the user boarding time is from 18 to 24, the slot in the time period is filled to evening, the user boarding time is acquired, and if the user boarding time is from 18 to 24, the slot in the time period is filled to morning. The parameter related to the slot filling rule of the Zamei slot is user image change, the slot filling rule is specifically that if the hairstyle of a user is changed, the Zamei slot is filled as the hairstyle, if the makeup of the user is changed, the Zamei slot is filled as the makeup, if the clothing of the user is changed, the Zamei slot is filled as the clothing, the image of the user A is obtained through a camera, the obtained image is analyzed and compared with the historical image, the hairstyle of the user is determined to be changed based on the comparison result, and the Zamei slot is filled as the hairstyle.
The first voice is generated according to the active conversation theme 'hello one' and the filled time period slot and the zam slot, for example, 'morning good, user A, your hairstyle today is really beautiful, and a little teak congratulate your happy mood today'.
If the user identity is identified as the user B in step 101, it is determined that the active dialog trigger set corresponding to the user identity is the active dialog trigger set 2. When a user B gets on the bus, the triggering condition 1 of the active dialogue triggering rule 1 in the active dialogue triggering set 2 is met, at this time, it is determined that an active dialogue needs to be initiated, the slot position of the slot is filled to morning according to the time of getting on the bus of the user, and a first voice is generated according to the active dialogue theme 'hello two' and the filled slot position of the slot position, for example, 'morning good, user B'.
Example three:
if the user identity is identified as the user a in step 101, the vehicle-mounted system acquires current road condition information through interaction with the server, so that it is determined that the triggering condition 1 of the active dialog triggering rule 2 in the active dialog triggering set 1 is satisfied, the vehicle-mounted system further triggers the camera to acquire a facial image of the user or triggers the voice acquisition device to acquire voice of the user, and current emotion of the user is obtained through means such as image recognition or voice recognition, so that it is determined that the triggering condition 2 of the active dialog triggering rule 2 in the active dialog triggering set 1 is satisfied, a first voice is generated according to the active dialog theme and at least one slot position, specifically, the play source slot position is filled according to a corresponding filling rule, and it is assumed that the filling rule is: if the vehicle-mounted system is connected with the mobile phone and the electric quantity of the mobile phone is sufficient, the playing source slot position is filled with the mobile phone, and if the vehicle-mounted system is located in an area with high broadcast signal intensity, the playing source slot position is filled with the broadcast. The specific filling process is similar to that of the second embodiment, and is not described here again. After the playing source slot position is filled, a first voice is generated according to the active conversation theme 'playing music' and the filled playing source slot position, for example, when the playing source slot position is filled with a mobile phone, the first voice can be 'congestion at the current road section, a music bar on the mobile phone is played by a person per kou', and when the playing source slot position is filled with a broadcast, the first voice can be 'congestion at the current road section, a music broadcasting bar is played by a person per kou'. According to the response of the user to the first voice, the vehicle-mounted system executes corresponding operation, for example, if the user answers ' good ', the vehicle-mounted system plays mobile phone music or music broadcast, and if the user does not answer ' good ', the vehicle-mounted system plays news information bar ', the vehicle-mounted system acquires the news information from the server and broadcasts the news information to the user.
