Technical Field

Background
The voice recognition technology is used to recognize a voice signal as a signal corresponding to a predetermined language based on a voice input by a user or the like, and can be applied to various fields.
The current voice interaction system based on the voice recognition technology generally supports single-round or multi-round voice interaction capability, but the interaction rhythm is fixed and is executed step by step strictly according to code logic. The dialogue rhythm here refers to two parts: the first part is that the system replies after the user sends out an instruction; the second part is that after the system gives a response, the user continues to give instructions. The first part of the current voice interaction system usually returns a result and immediately broadcasts and displays the result to a user after the system finishes recognition and understanding and necessary service requests; the second part of the current voice interaction system generally needs to start a recorder after the system broadcasting is finished, wait for the user to speak, or allow the user to start speaking and give feedback before the system finishes broadcasting, but when the system broadcasting is finished and waits for the user feedback, if the user does not speak late, the system will report an error and stop monitoring the user feedback information after a preset time.
In the process of implementing the present invention, the inventor finds that the existing voice interaction system has the following defects: the time when the voice interaction system feeds back the recognition result to the user and the time when the voice interaction system waits for the feedback of the user are both uncontrollable by the user or cannot be dynamically adjusted in real time according to the user requirements.

Accordingly, as shown in fig. 1, the method comprises the following operations:
step 101, monitoring position information between the device and the obstacle or speed information of the device.
Optionally, the position information between the device and the obstacle includes: a first distance between the device and an immediately preceding obstacle, a second distance between the device and an anterior lateral obstacle, and/or an azimuth angle between the device and the anterior lateral obstacle; the speed information of the vehicle includes: a speed and/or acceleration of the vehicle. Optionally, when the apparatus is a vehicle, the forward side obstacle comprises a forward side motor vehicle, a forward side non-motor vehicle and/or a forward side pedestrian.
Illustratively, the device may include a vehicle, and may also include an electronic device such as a mobile phone or a platform computer. In the embodiment of the invention, when the equipment is a vehicle, the feedback mode of the voice interaction system in the vehicle can be adjusted through the technical scheme provided by the embodiment of the invention; when the device is other electronic devices, the feedback mode of the voice interaction system in the device can be adjusted by analyzing the relevant information of the user when the user uses the electronic device in a static state or a moving state. The following explains the feedback mode adjustment scheme provided by the embodiment of the invention by using the device as a vehicle.
In the embodiment of the invention, in the process of driving a vehicle by a user, position information between the vehicle and an obstacle or speed information of the vehicle is monitored in real time at preset time intervals. For example, Position information between the vehicle and an obstacle is monitored by a camera in an ADAS (advanced driver Assistance System) in the vehicle, and speed information of the vehicle is monitored by an acceleration sensor and a GPS (Global positioning System) in the vehicle. It is understood that the obstacle in front of the vehicle includes a motor vehicle in front of the vehicle, a non-motor vehicle in front of the vehicle, and a pedestrian in front of the vehicle, and the obstacle in front of the vehicle is usually a motor vehicle in front of the vehicle according to an actual driving scene; the front side obstacle includes a front side motor vehicle, a front side non-motor vehicle, and a front side pedestrian, and therefore, monitoring the position information between the vehicle and the obstacle includes: the distance between the vehicle and the vehicle directly in front, the distance between the vehicle and the vehicle on the front side, the azimuth angle between the vehicle and the vehicle on the front side, the distance between the vehicle and the pedestrian on the front side (non-motor vehicle), and the azimuth angle between the vehicle and the pedestrian on the front side (non-motor vehicle) are monitored.

In the embodiment of the invention, the process of the voice interaction system in the vehicle interacting with the user comprises two processes of providing feedback information to the user by the voice interaction system (namely the user waits for the voice interaction system to give feedback) and inputting a control instruction to the voice interaction system by the user (namely the voice interaction system waits for the user to feed back). The method includes analyzing position information to judge whether a vehicle is about to have an emergency or not, and if yes, adjusting a feedback mode of a voice interaction system when a user waits for the voice interaction system in the vehicle to give feedback information, or adjusting a mode of the voice interaction system waiting for the user to feed back when the voice interaction system in the vehicle waits for the user to input a control instruction. And analyzing the speed information to judge whether the vehicle has an emergency, if so, adjusting a feedback mode of the voice interaction system when the voice interaction system in the vehicle waits for feedback information given by the user, or adjusting a mode of the voice interaction system waiting for feedback of the user when the voice interaction system in the vehicle waits for a control instruction input by the user.

For example, historical position information at each time during the vehicle driving process in the latest time period (for example, within one month) is acquired, wherein the historical position information comprises historical distance between the vehicle and the obstacle right ahead, historical distance between the vehicle and the front side obstacle, and azimuth angle between the vehicle and the front side obstacle.

In the embodiment of the invention, whether the first distance is smaller than the first safe reaction distance is judged, and when the first distance is smaller than the first safe reaction distance, the fact that the vehicle is too close to the vehicle right in front is meant, and an emergency situation is likely to happen. And judging whether the second distance is smaller than the second safe reaction distance, and when the second distance is smaller than the second safe reaction distance, the fact that the vehicle and the obstacle (motor vehicle, non-motor vehicle or pedestrian) at the front side are too close to each other at a certain future time point is meant, so that an emergency situation is likely to occur. Therefore, when the first distance is less than the first safe reaction distance or the second distance is less than the second safe reaction distance, it is determined that the vehicle is about to have an emergency. Optionally, when the duration that the first distance is greater than the first safe reaction distance and the second distance is greater than the second safe reaction distance is greater than the preset time threshold, it may be predicted that the vehicle is about to release the emergency condition, that is, the vehicle does not have the emergency condition.

As shown in fig. 2, for ease of understanding, the explanation will be made with the front-side obstacle divided into a front-side vehicle and a front-side pedestrian.
Optionally, determining that the device has an emergency according to the speed information includes: calculating the speed range of the equipment within a preset time period; calculating the acceleration range of the equipment within a preset time period; determining that an emergency condition has occurred for the device when the speed of the device exceeds the speed range or the acceleration of the device exceeds the acceleration range.
Determining that an emergency condition has occurred for the vehicle based on the speed information, comprising: acquiring a pre-generated speed prediction function, wherein the speed prediction function comprises a first speed prediction function and a second speed prediction function; the first speed prediction function is the corresponding relation between the speed and the time in the running process of the vehicle; the second speed prediction function is the corresponding relation between the acceleration and the time in the running process of the vehicle; calculating the speed range of the vehicle within a preset time period according to the first speed prediction function; calculating the acceleration range of the vehicle within a preset time period according to the second speed prediction function; determining that an emergency condition has occurred with the vehicle when the speed of the vehicle is outside the speed range or the acceleration of the vehicle is outside the acceleration range.
For example, historical speed information at various moments during the running of the vehicle in the recent time period (e.g., within one month) is acquired, wherein the historical speed information comprises the acceleration and the speed of the vehicle. Performing quadratic curve fitting on the basis of the historical speed of the vehicle in the latest time period to generate a first speed prediction function V (t), wherein the first speed prediction function is the corresponding relation between the speed and the time in the running process of the vehicle, performing quadratic curve fitting on the basis of the historical acceleration of the vehicle in the latest time period to generate a second speed prediction function A (t), wherein the second speed prediction function is the corresponding relation between the acceleration and the time in the running process of the vehicle1Speed range of inner vehicle [ v ]low,vhigh](ii) a Calculating a preset time period T according to a second speed prediction function A (t)1Acceleration range of inner vehicle [ a ]low,ahigh].

Determining that an emergency condition has occurred in the vehicle when the speed of the vehicle exceeds the speed range or the acceleration of the vehicle exceeds the acceleration range; and when the speed of the vehicle is in the speed range and the acceleration of the vehicle is in the acceleration range, determining that the vehicle does not have the emergency condition, namely that the vehicle is out of the emergency condition.
Fig. 3 is a schematic flow chart of determining that an emergency situation has occurred in a vehicle according to an embodiment of the present invention.
Optionally, when it is predicted that the emergency situation of the device is about to occur according to the location information, adjusting a feedback mode of a voice interaction system in the device includes: when the emergency situation of the equipment is predicted to occur according to the position information, first feedback information of a voice interaction system in the equipment is added until the emergency situation of the equipment is predicted to be relieved according to the position information; wherein the first feedback information comprises prompt information prompting a user to concentrate on using the device. For example, when it is determined that the vehicle is about to have an emergency, if the user waits for the voice interaction system in the vehicle to give feedback, the first feedback information of the voice interaction system is added, for example: please pay attention to the front vehicle/pedestrian to inform the user of dangerous conditions, and prompt the user to pay attention to driving until no emergency or the emergency is relieved, and then the voice interaction system continues to provide corresponding feedback information according to the control instruction input by the user.
Optionally, when it is predicted that the emergency situation of the device is about to occur according to the location information, adjusting a manner in which a voice interaction system in the device waits for user feedback includes: when the emergency situation of the equipment is predicted to occur according to the position information, temporarily storing the interaction information between a voice interaction system in the equipment and the user, and increasing second feedback information of the voice interaction system until the emergency situation of the equipment is predicted to be relieved according to the position information; and the second feedback information comprises prompt information for prompting the voice interaction system to wait for a user to input a control instruction. For example, when it is determined that the vehicle is about to have an emergency, if the voice interaction system in the vehicle waits for the user to give feedback, second feedback information of the voice interaction system is added, for example, "please pay attention to the front vehicle/pedestrian, the system can wait for patiently" to prompt the user to concentrate on driving without hurry to input a control command to the voice interaction system; meanwhile, the interactive information between the voice interactive system and the user is temporarily stored until the user continues to input the control instruction subsequently, and the interaction between the voice interactive system and the user does not need to start from the beginning.
Optionally, when it is determined that the device has the emergency according to the speed information, adjusting a feedback mode of a voice interaction system in the device includes: and when the equipment is determined to have the emergency according to the speed information, controlling a voice interaction system in the equipment to suspend providing feedback information for the user until the equipment is determined to be out of the emergency according to the speed information. For example, when it is determined that the vehicle has an emergency, if the user waits for the voice interactive system to give feedback, the voice interactive system is controlled to suspend providing any feedback information to the user, and after the emergency is released, the voice interactive system resumes providing corresponding feedback information for the control instruction input by the user.
Optionally, when it is determined that the device has an emergency according to the speed information, adjusting a manner in which a voice interaction system in the device waits for user feedback includes: when the emergency situation of the equipment is determined according to the speed information, the interactive information between the voice interactive system in the equipment and the user is temporarily stored until the emergency situation of the equipment to be relieved is predicted according to the position information, and the voice interactive system is controlled to prompt the user to input a control instruction. For example, when it is determined that the vehicle is in an emergency, if the voice interactive system waits for the user to give feedback, the system temporarily stores the interactive progress between the system and the user, and guides the user to continue inputting through a dialog after the emergency is relieved. For example, "you can continue to tell me which choice you are", at which point the user can input control instructions directly to the system without waking up the voice interactive system.
