Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
During the driving process of a vehicle, a person inside the vehicle may need to communicate with a person outside the vehicle by voice, and the common method is to shake down a window and communicate with the person outside the vehicle directly by the person inside the vehicle (directly speaking with mouth and listening with ears), but the close-range on-the-spot communication method may have the following problems: (1) if the distance between the person outside the vehicle and the vehicle is far, the person inside the vehicle is not clearly heard probably because the voice of the person outside the vehicle is small, and the distance between the vehicle and the person outside the vehicle needs to be shortened at the moment; (2) the close-distance in-place communication is easily affected by virus infection or environment due to the influence of bad weather such as epidemic situation or sand storm; (3) when the people in the vehicle belong to the weak individual (such as a female driver), the people outside the vehicle may be related to the personal safety problem for the people in the vehicle, and if the people outside the vehicle are directly communicated with the people outside the vehicle in close range in the face through voice, certain safety risk exists.
One of the core ideas of the embodiment of the invention is to realize the bidirectional voice communication between the personnel in the automobile and the personnel outside the automobile by establishing a bidirectional communication channel between the inside of the automobile and the outside of the automobile, avoid adopting a direct on-the-spot short-distance communication mode, not only enhance the received and sent voice, but also realize the effective communication between the personnel in the automobile and the personnel outside the automobile under the condition of not opening windows, and enhance the personal protection.
Referring to fig. 1, a flow chart of steps of a vehicle-based voice communication method according to the present invention is shown, which may specifically include the following steps:
in the invention, effective communication between the person in the vehicle and the person outside the vehicle is realized under the condition of not opening the vehicle window, voice information for the two-way communication is required to be acquired firstly, and at the moment, the operation of the person in the vehicle can be responded, and the vehicle is controlled to acquire the voice information for the two-way communication, so that the two-way voice communication between the person in the vehicle and the person outside the vehicle can be realized based on the acquired voice information.
The collected voice information for the two-party communication can comprise in-vehicle voice information of people inside the vehicle and out-vehicle voice information of people outside the vehicle.
In practical application, personnel in the vehicle have control authority to collect voice information inside and outside the vehicle, and the responded user operation can be trigger operation for collecting the voice information inside and outside the vehicle. In specific implementation, the trigger for acquiring the voice information inside and outside the vehicle can be the trigger actively performed by the person inside the vehicle, or the trigger performed by the person inside the vehicle after the detection outside the vehicle.
Under the condition that the personnel in the vehicle actively triggers, the voice information collecting operation which is actively carried out by the personnel in the vehicle and is used for the voice information inside and outside the vehicle is received, and the vehicle can be controlled to respectively collect the voice information inside the vehicle and the voice information outside the vehicle of the personnel outside the vehicle, so that the voice communication inside and outside the vehicle is realized.
The in-vehicle personnel have control authority for collecting the in-vehicle and out-vehicle voice information, and can be represented as control authority for a voice communication channel between the in-vehicle personnel and the out-vehicle personnel, namely the in-vehicle and out-vehicle voice information can be collected on the basis of opening the voice communication channel between the in-vehicle personnel and the out-vehicle personnel, and the in-vehicle and out-vehicle voice communication is realized.
Under the condition that the personnel in the vehicle triggers after the detection outside the vehicle, when the vehicle detects the voice information of the personnel outside the vehicle and/or recognizes that the distance between the personnel outside the vehicle and the vehicle is less than a preset distance threshold value, the voice communication channel between the personnel in the vehicle and the personnel outside the vehicle can be opened according to the operation of the personnel in the vehicle.
Specifically, after the vehicle performs the external detection, the vehicle may send a prompt message to the vehicle interior personnel to prompt the vehicle interior personnel whether to open a voice communication channel between the vehicle interior personnel and the vehicle exterior personnel. The prompt message can be generated based on the fact that the vehicle detects the person outside the vehicle with the voice communication intention, and the judging mode of the person outside the vehicle with the voice communication intention can be determined by detecting voice information of the person outside the vehicle and/or recognizing that the distance between the person outside the vehicle and the vehicle is smaller than a preset distance threshold value.
In practical applications, voice information of a person outside the vehicle can be detected by performing VAD (voice activity detection) detection with a microphone located outside the vehicle. VAD detection is mainly used for detecting whether a voice signal exists or not, and can remove a mute component contained in the detected voice signal to obtain effective voice information, personnel outside a vehicle are in the environment outside the vehicle, noise is too noisy, the phenomenon that voice conflicts or the voice is in a far area or has the voice in a large screen playing video outside the vehicle can occur, and at the moment, VAD detection can be misjudged.
In this case, the determination of the person outside the vehicle with the voice communication intention may be implemented together with image recognition of the vehicle, that is, the vehicle may have at least one camera in combination with image recognition based on VAD detection, the camera may be used to recognize images in different directions, if it is recognized that a person outside the vehicle approaches, for example, the distance from the person outside the vehicle is less than a preset distance threshold, it is determined that the person outside the vehicle with the voice communication intention exists outside the vehicle, and at this time, it may be prompted whether the person inside the vehicle triggers opening of a voice communication channel between the person inside the vehicle and the person outside the vehicle.
And 102, realizing voice communication between the inside and the outside of the vehicle according to the voice information inside the vehicle and the voice information outside the vehicle.
After the voice information inside the vehicle and the voice information outside the vehicle are collected, the bidirectional voice communication between the person inside the vehicle and the person outside the vehicle can be realized based on the established bidirectional communication channel between the person inside the vehicle and the person outside the vehicle, namely the voice communication channel between the person inside the vehicle and the person outside the vehicle.
Specifically, the voice information inside the vehicle can be played to the personnel outside the vehicle, and the voice information outside the vehicle can be played to the personnel inside the vehicle, so that the voice communication inside and outside the vehicle can be realized.
The source of the voice information can be determined in the process of playing the voice information based on the established two-way communication channel inside and outside the vehicle, the information source can be divided based on the inside and the outside of the vehicle, and the voice information can be played based on the established two-way communication channel according to the voice communication direction corresponding to the information source. For example, when the collected in-vehicle voice information is determined to be information from the inside of the vehicle, the voice communication direction of the in-vehicle information can be determined to be from the inside of the vehicle to the outside of the vehicle, and at the moment, the in-vehicle voice information can be played to people outside the vehicle; when the collected voice information outside the vehicle is determined to be the information from outside the vehicle, the voice communication direction of the information outside the vehicle can be determined to be from outside the vehicle to inside the vehicle, and the voice information outside the vehicle can be played to the person inside the vehicle.
In the invention, under the condition that the vehicle window is not opened, the vehicle can be controlled to collect the in-vehicle voice information of the in-vehicle personnel and the out-vehicle voice information of the out-vehicle personnel in response to the operation of the in-vehicle personnel, and the in-vehicle and out-vehicle voice communication is realized based on the collected in-vehicle voice information and the out-vehicle voice information. Through establishing a bidirectional communication channel between the interior of the vehicle and the exterior of the vehicle, bidirectional voice communication between personnel in the vehicle and personnel outside the vehicle is realized, received and sent voices are enhanced, and the purpose of effectively communicating between the personnel in the vehicle and the personnel outside the vehicle under the premise of not opening a vehicle window is achieved.
Referring to fig. 2, a flow chart of steps of another vehicle-based voice communication method of the present invention is shown, which may specifically include the following steps:
in the invention, the vehicle can be controlled to respectively collect the in-vehicle voice information of the in-vehicle personnel and the out-vehicle voice information of the out-vehicle personnel in response to the operation of the in-vehicle personnel, so that the two-way voice communication between the in-vehicle personnel and the out-vehicle personnel can be realized based on the collected in-vehicle and out-vehicle voice information.
In practical application, for the collection of the voice information outside the vehicle, the personnel outside the vehicle are in the environment outside the vehicle, the noise is too noisy, the phenomenon that the voice conflicts or the voice is in a far area or has the voice in the video played on a large screen outside the vehicle can possibly occur, the target voice area of the personnel outside the vehicle can be firstly determined, and then the voice information belonging to the target voice area is collected through a microphone located outside the vehicle body.
Specifically, the direction of the person outside the vehicle can be taken as a set direction during beam forming, the microphone array outside the vehicle is taken as the set direction according to the direction of the person outside the vehicle relative to the vehicle to carry out beam forming, and the range area pointed by the beam is taken as a target sound area, so that the microphone array outside the vehicle is pointed to the person outside the vehicle, and only the voice information of the person outside the vehicle is collected; in another mode, the target sound area can be determined through interactive response of a User Interface (UI), an icon or a key displayed on the UI can establish a control logic with a microphone array located outside the vehicle, and a sound reception direction can be determined by a person inside the vehicle based on a sound direction selected to be acquired, so that the voice information outside the vehicle can be acquired by the target sound area of the person outside the vehicle.
Step 202, broadcasting voice information inside the vehicle to personnel outside the vehicle, and broadcasting voice information outside the vehicle to personnel inside the vehicle, so as to realize voice communication inside and outside the vehicle.
The collection and playing of the voice information inside the vehicle and the voice information outside the vehicle can be realized through voice communication channels of personnel inside the vehicle and personnel outside the vehicle, and specifically can be realized based on an audio communication link established by a vehicle machine system, and the established audio communication link can comprise an uplink communication link and a downlink communication link.
In practical application, the control authority of the in-vehicle person on the voice communication channel between the in-vehicle person and the out-vehicle person can be actually expressed as a switching authority of a vehicle voice communication mode, specifically, the vehicle voice communication mode can include an in-vehicle voice communication mode and an in-vehicle and out-vehicle voice communication mode, the in-vehicle voice communication mode can refer to that an in-vehicle microphone collects voice information of the in-vehicle person and transmits the voice information to a vehicle-mounted large screen to realize corresponding voice control, and the in-vehicle and out-vehicle voice communication mode can refer to that the voice information of the in-vehicle person collected by the in-vehicle microphone is transmitted to a speaker or a loudspeaker located on the vehicle body and facing outward to be played through an established communication link.
It should be noted that the switching of different voice communication modes can be represented as switching of corresponding audio communication links of the modes, and the switching of the audio communication links can be actually equivalent to the selection of a sound card on a computer or the switching of a bluetooth headset, a loudspeaker or a receiver on a mobile phone; or the user can see different images by switching the front camera and the rear camera of the mobile phone as in the case of video call, and the selectable path is presented to the user and can be realized by performing corresponding driving configuration on the bottom layer of the system.
When the collection of the voice information inside and outside the vehicle is triggered, the voice communication mode of the vehicle can be switched to the voice communication mode inside and outside the vehicle, and at this time, the collected voice information inside and outside the vehicle can be bidirectionally transmitted and played through an audio channel (an up-down communication link as shown in fig. 3) corresponding to the voice communication mode inside and outside the vehicle.
In an optional embodiment, the voice communication mode of the vehicle is switched to the voice communication mode between the inside and the outside of the vehicle by the person in the vehicle, and if the person in the vehicle does not need to communicate with the person outside the vehicle at this time, the voice communication mode of the vehicle can be switched to the voice communication mode in the vehicle, which can be realized by switching an audio channel link, that is, switching the audio channel of the microphone in the vehicle to voice interaction between the person in the vehicle and the large vehicle-mounted screen instead of voice communication between the person outside the vehicle.
Referring to fig. 3, a schematic diagram of an uplink and downlink communication link established in the embodiment of the present invention is shown.
The established uplink communication link can be represented as an internal communication link for a microphone positioned on the vehicle body and facing outwards, the communication link can realize that personnel outside the vehicle speak to personnel inside the vehicle, and the personnel inside the vehicle listen to the speaking channel of the personnel outside the vehicle, specifically, the microphone A positioned on the vehicle body and facing outwards is used as an input interface of the system, the collected speech signal outside the vehicle is converted into an electric signal and is input into the system as an uplink signal to be subjected to noise reduction, echo elimination, human voice enhancement, signal amplification and other processing, the processed electric signal is converted into a speech signal again through a loudspeaker B inside the vehicle, and the speech signal is played by adopting proper volume, so that the personnel inside the vehicle can clearly hear the speaking content of the personnel outside the vehicle, and the speech information outside the vehicle is played.
The established downlink communication link can be represented as a communication link which is external to an in-vehicle microphone, and can realize that personnel in the vehicle speak to people outside the vehicle, and the personnel outside the vehicle listen to the channel of the personnel in the vehicle, specifically, the microphone C positioned in the vehicle is used as an input interface of the system, the collected in-vehicle voice signal is converted into an electric signal and is input into the system as a downlink signal to be subjected to noise reduction, echo cancellation, human voice enhancement, signal amplification and other processing, the processed electric signal is converted into a voice signal again through a loudspeaker D positioned outside the vehicle, and then the processed electric signal is played through a loudspeaker D positioned outside the vehicle as an output interface of the system with proper volume, so that the personnel outside the vehicle can clearly hear the speaking content of the personnel in the vehicle, and the playing of the voice information in the vehicle is completed.
