Description

Technical Field

[0001] The present disclosure relates to the technical field of automobiles, and particularly relates to an in-vehicle call method, device, equipment and computer-readable storage medium. Background Art

[0002] When the interior space of a vehicle is large, for example, some vehicle models can be equipped with three rows of seats. Various noises generated during the driving of these vehicles will affect the conversation of passengers in different seats in the vehicle cockpit.

[0003] Related technologies usually adopt ICC (In Car Communication) to solve this technical problem.

[0004] However, the existing ICC system depends on the in-vehicle system audio framework, and requires the algorithm chip in the in-vehicle system audio framework to perform active noise reduction on the collected sound information. This results in certain requirements for the computing power of the AUD (Audio Processing Unit) and the hardware capabilities such as power amplifiers already installed in the in-vehicle system, and the universality is relatively poor. Summary of the Invention

[0005] To overcome the problems existing in the related technologies, the present disclosure provides an in-vehicle call method, device, equipment and computer-readable storage medium, which can solve the above problems.

[0006] According to the first aspect of the embodiments of the present disclosure, an in-vehicle call method is provided, which is applied to a call application program deployed in the vehicle's in-vehicle system. The method includes:

[0007] Obtain the mixed audio collected by the audio collection device installed at the first position in the vehicle cockpit;

[0008] Identify and separate the human voice component and the noise component in the mixed audio;

[0009] Send the human voice component to the audio playback device installed at the second position in the cockpit for playback.

[0010] According to the second aspect of the embodiments of the present disclosure, an in-vehicle call device is provided, which is applied to the vehicle's in-vehicle system. The device includes:

[0011] An obtaining unit, configured to obtain the mixed audio collected by the audio collection device installed at the first position in the vehicle cockpit;

[0012] An identifying unit, configured to identify and separate the human voice component and the noise component in the mixed audio;

[0013] A sending unit, configured to send the human voice component to an audio playback device assembled at a second position inside the cockpit for playback.

[0014] According to a third aspect of the embodiments of the present disclosure, there is provided an electronic device, including: a processor and a memory;

[0015] The memory is used to store a computer program;

[0016] The processor is configured to execute the in-vehicle call method as described in the first aspect by calling the computer program.

[0017] According to a fourth aspect of the embodiments of the present disclosure, there is provided a computer-readable storage medium, on which a computer program is stored, and when the program is executed by a processor, it implements the in-vehicle call method as described in the first aspect.

[0018] According to a fifth aspect of the embodiments of the present disclosure, there is provided a computer program product, including a computer program, and when the computer program is executed by a processor, it implements the method as described in the first aspect.

[0019] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects:

[0020] The present disclosure proposes an in-vehicle call method, which is not implemented through the in-vehicle system audio framework, but is applied to a call application deployed in the in-vehicle system. The method of the present disclosure can obtain the mixed audio collected by an audio acquisition device at a first position, split the mixed audio to determine the human voice component and the noise component, and only send the human voice component to an audio playback device at a second position for playback, thereby realizing in-vehicle calls.

[0021] Compared with the ICC system, the present disclosure does not perform noise reduction by actively reducing noise (outputting an anti-phase signal of the noise), but separates the human voice component and the noise component in the mixed audio, obtains the pure human voice component and then sends it to the playback device for playback. This noise reduction method enables the solution of the present disclosure to be independent of the in-vehicle system audio framework and can be realized by a pure software method through an application program. The in-vehicle call method of the present disclosure has a better in-vehicle call effect and relatively low requirements for hardware devices, does not require a high-performance audio processing chip, and thus has stronger universality and can be applied to more vehicles.

[0022] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure. Description of the Drawings

Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to a determination".

[0032] To solve the above technical problems, the present disclosure proposes an in-vehicle call method.

[0033] Figure 1FIG. 0 is a schematic flowchart of an in-vehicle call method shown according to an embodiment of the present disclosure. The in-vehicle call method can be applied to a call application deployed in the in-vehicle system of a vehicle. The application can be deployed in the in-vehicle system by means such as presetting or OTA (Over-The-Air). The in-vehicle call method can be used for voice communication between passengers at different positions in the vehicle cockpit.

[0034] As Figure 1 shown, the in-vehicle call method includes:

[0035] In step S101, obtain the mixed audio collected by the audio collection device assembled at the first position in the vehicle cockpit;

[0036] In step S102, identify and separate the human voice component and the noise component in the mixed audio;

[0037] In step S103, send the human voice component to the audio playback device assembled at the second position in the cockpit for playback.

[0038] In some embodiments, audio collection devices and / or audio playback devices are provided at different positions of the vehicle.

[0039] For example, audio playback devices can be provided on the headrests and doors corresponding to each position in the vehicle cockpit, and audio collection devices can be provided on the seat belts at each position in the vehicle cockpit.

[0040] In some embodiments, obtain the mixed audio collected by the audio collection device assembled at the first position in the vehicle cockpit.

[0041] The audio collection device assembled at the first position can collect the mixed audio and generate a corresponding audio file. The audio file can be received from the audio collection device to obtain the mixed audio collected by the audio collection device.

[0042] For the audio collection device, the audio collection device only needs to collect the mixed audio to generate an audio file and send the audio file, without the need to process the collected audio file through complex algorithms, thereby reducing the dependence on the chip computing power on the audio collection device side.

[0043] In some embodiments, the interaction between the in-vehicle system and the audio collection device and the audio playback device can be achieved through the in-vehicle bus or through the network for data transmission.

[0044] The audio file can be transmitted through the in-vehicle bus or wirelessly through the network.

[0045] In some embodiments, the human voice component and the noise component in the mixed audio are identified and separated.

[0046] The mixed audio collected by the audio acquisition device at the first position may include a human voice component and a noise component. The human voice component and the noise component in the mixed audio can be identified, and the two can be further separated to obtain a pure human voice component.

[0047] There are certain differences between the human voice component and the noise component, and they can be identified and separated based on a preset algorithm. The separated human voice component is relatively pure and does not contain noise when played, thus ensuring that the call content is relatively clear.

[0048] In some embodiments, the human voice component is sent to the audio playback device installed at the second position in the cockpit for playback.

[0049] After the call application program of the in-vehicle system completes the identification and separation of the mixed audio, it can send the obtained human voice component after separation to the audio playback device at the second position.

[0050] After receiving the human voice component, the audio playback device located at the second position can directly play the human voice component without the need for further noise reduction, amplification, etc. Therefore, the method of the present disclosure can also reduce the dependence on the chip computing power at the audio playback device, save costs, and ensure the universality of the solution.

[0051] In some embodiments, the first position is different from the second position.

[0052] The first position and the second position can be any two different positions in the vehicle cockpit. For example, they can be the driver's seat in the first row and the seat in the second row, or the seat in the second row and the seat in the third row. The present disclosure does not limit this.

[0053] For the in-vehicle call method proposed by the present disclosure, the processing and analysis of the collected mixed audio are performed by the call application program deployed in the in-vehicle system. This application program can identify and separate the human voice component and the noise component in the mixed audio, and only send the human voice component to the audio playback device for playback.

[0054] Since the noise reduction strategy adopted in the present disclosure is not active noise reduction, complex algorithm processing is not required on the side of the audio playback device. The audio playback device only needs to play the received audio file. On the other hand, the processing and analysis of the mixed audio are all performed by the application program. Therefore, it is not necessary for the audio acquisition device to preprocess the collected mixed audio. This enables the in-vehicle call method proposed in the present disclosure to bypass the system audio framework in the vehicle, making the method of the present disclosure applicable to any vehicle equipped with an audio acquisition device and an audio playback device, with extremely low requirements for the computing power of the hardware chip and stronger universality. Moreover, the present disclosure separates the mixed audio into pure human voice components, ensuring the call quality and enabling passengers at different positions in the vehicle to communicate well.

[0055] In some embodiments, identifying and separating the human voice component and the noise component in the mixed audio includes: performing spectral analysis on the mixed audio and determining the human voice component according to the analysis result.

[0056] The frequency bands where the human voice component and the noise component are located are different. Usually, the human voice component is located in the middle frequency band. Therefore, the human voice component part and the noise component part in the mixed audio can be determined through spectral analysis.

[0057] In some embodiments, the spectral analysis may further include: echo cancellation.

[0058] Based on noise reduction methods such as echo cancellation, a purer human voice component can be separated.

[0059] In some embodiments, the method further includes: acquiring the ambient audio in the vehicle cockpit; the performing spectral analysis on the mixed audio includes: using the ambient audio as a reference, separating the frequency band in the mixed audio that matches the ambient audio as the noise component, and separating the frequency band that does not match the ambient audio as the human voice component.

[0060] To more accurately distinguish the human voice component and the noise component, the ambient audio in the vehicle cockpit can be collected through the audio acquisition device. The ambient audio is the ambient noise.

[0061] After acquiring the ambient audio, the ambient audio can be used as a reference. The part of the mixed audio that matches the ambient audio is used as the noise component, and the part that does not match is used as the human voice component. Through spectral analysis, during the process of extracting the human voice component, the spectrum that matches the ambient audio can be cropped, so as to separate the pure human voice component.

[0062] Compared with directly performing spectral analysis according to the high and low of the frequency band, distinguishing the human voice component and the noise component based on the reference of the ambient audio can be more accurate and precise, which helps to obtain a pure human voice component, thus achieving the effect of noise reduction.

[0063] In some embodiments, obtaining the ambient audio in the vehicle cockpit includes: obtaining the ambient audio collected by an audio collection device installed at a non-first position in the vehicle cockpit.

[0064] Since the environment in the vehicle cockpit is relatively enclosed and the space is relatively small, the ambient noise caused by vehicle driving and the like does not differ much. It can be considered that the ambient noise at different positions is similar. Therefore, when a passenger at the first position speaks and the audio collection device at the first position collects the mixed audio, the ambient audio can be collected by the audio collection devices installed at other positions, so as to determine the ambient audio at the same moment corresponding to the human voice component in the mixed audio.

[0065] In some embodiments, obtaining the ambient audio in the vehicle cockpit includes: obtaining the ambient audio collected by the audio collection device installed at the first position during a non-call period.

[0066] In this embodiment, it can be considered that the ambient audio in the vehicle cockpit does not change drastically within a certain period of time, and the audio collection devices at different positions may record different audio contents (for example, music is played at the first position, and this music will affect the audio collected by the audio collection device at the first position, but it is difficult to affect the audio at other positions). Therefore, the audio collected by the audio collection device at the first position during the non-call period can be obtained as the ambient audio, and the mixed audio can be separated by using this ambient audio. Although the ambient audio obtained in this way is not at the same moment as the mixed audio, it has a certain position uniqueness and can collect the unique ambient noise at this first position.

[0067] In some embodiments, the method further includes: enhancing the volume of the human voice component; sending the human voice component to an audio playback device installed at a second position in the cockpit for playback includes: sending the human voice component with enhanced volume to the audio playback device installed at the second position in the cockpit for playback.

[0068] To ensure that the human voice component separated from the mixed audio can be clearly heard by the passenger at the second position, the obtained human voice component can be enhanced in volume. After enhancing the volume of the human voice component, the enhanced human voice component is sent to the audio playback device for playback by the audio playback device.

[0069] It should be noted that since enhancing the volume of the human voice component is one of the steps in the call application's audio processing, the audio file actually sent by the call application to the audio playback device already has an enhanced volume. Therefore, in the present disclosure, enhancing the volume of the human voice component does not require the use of the algorithm computing power on the audio playback device side (such as the chip algorithm on the amplifier). The audio playback device only needs to play the audio according to the instructions in the received audio file.

[0070] In the present disclosure, the enhancement of the volume of the human voice component is not to send a volume enhancement instruction to the audio playback device and then have the audio playback device perform volume enhancement processing, but to directly enhance the volume of the audio file of the human voice component. The audio playback device can directly play the received audio file. This method further reduces the hardware requirements for the audio playback device and increases the applicability of the method of the present disclosure.

[0071] In some embodiments, enhancing the volume of the human voice component includes: obtaining the condition information of the vehicle; wherein the condition information includes at least one of vehicle speed, air conditioner air volume, and window opening condition; determining a volume compensation value according to the condition information; and performing volume compensation on the human voice component based on the determined volume compensation value.

[0072] The call application can obtain the condition information of the vehicle by calling other modules in the vehicle system. The condition information can include information such as vehicle speed, air conditioner air volume, and window opening condition that may affect the ambient noise.

[0073] After obtaining the condition information of the vehicle, the volume compensation value can be determined based on a preset algorithm, corresponding relationship, etc., and then volume compensation is performed on the human voice component.

[0074] The faster the vehicle speed, the greater the air conditioner air volume, the more windows are opened or the greater the degree of window opening, which will all bring greater in-vehicle noise. Therefore, the determined volume compensation value is larger, and more compensation needs to be performed on the human voice component.

[0075] Although the embodiments of the present disclosure can separate the pure human voice component from the mixed audio, this only removes the noise in the audio collected at the first position. When the human voice component is played at the second position, the passengers at the second position may still be interfered by the in-vehicle noise, resulting in an inability to clearly hear the human voice component. Therefore, in this embodiment, by determining the condition information of the vehicle and then determining the volume compensation value, the volume of the human voice component is further compensated.

[0076] Based on this embodiment, for the same human voice component, when the vehicle is traveling at a speed of 30 kilometers per hour and 50 kilometers per hour, the volume of the human voice component played at the second position is not the same after compensation. The compensation value corresponding to a speed of 50 kilometers per hour is greater, and the volume of the human voice component is also greater. This enables passengers at the second position to hear a clearer human voice component under any conditions, without being unable to clearly hear the pure human voice component due to excessive in-vehicle noise.

[0077] In some embodiments, the method further includes: obtaining the interference noise collected by the audio acquisition device assembled at the second position; determining a volume compensation value based on the interference noise; and performing volume compensation on the human voice component based on the determined volume compensation value.

[0078] In addition to determining the volume compensation value based on the vehicle's condition information through the above embodiments, it is also possible to obtain the actual interference noise at the second position through the audio acquisition device assembled at the second position, and determine the volume compensation value based on this interference noise. This embodiment can more accurately determine the volume compensation value, enabling passengers at the second position to clearly hear the human voice component.

[0079] In some embodiments, the method further includes: receiving a first instruction; and determining the first position and the second position where a call needs to be made according to the first instruction.

[0080] The user initiates the first instruction. The user can be a passenger located at the first position and / or the second position who needs to communicate, or the driver. The first instruction needs to at least indicate two positions in the vehicle cockpit where communication is required.

[0081] For example, the first instruction can indicate that the first position determined in the vehicle cockpit speaks and the second position receives; or it can indicate that a call needs to be made between two positions in the vehicle cockpit. In this case, these two positions are both the first position and the second position at the same time.

[0082] Since the call application needs to obtain the mixed audio file collected at the first position and send the human voice component audio file to the second position, it is necessary to clarify the first position and the second position.

[0083] In some embodiments, the second position may include at least one position other than the first position.

[0084] In this embodiment, the speech of the passenger at the first position can be heard by passengers at multiple positions, and it can be applied to scenarios of multi-person communication.

[0085] Figure 2 It is a schematic diagram of the architecture of an in-vehicle call system shown according to an embodiment of the present disclosure.

[0086] AsFigure 2 As shown in the figure, the in-vehicle communication system includes an audio acquisition device 210, a terminal 220, and an audio playback device 230. Among them,

[0087] The audio acquisition device 210 is used to record sounds and send the acquired audio files to the terminal 220;

[0088] A call application program for executing the in-vehicle communication method proposed in this disclosure runs in the terminal 220. This program can process and analyze the audio files containing mixed audio sent by the audio acquisition device 210, and send the audio files containing pure human voice components obtained from the processing to the audio playback device 230 for playback; the terminal 220 can be an in-vehicle terminal device, and the call application program can be an application program deployed and running in the in-vehicle system; or, when a wireless connection is established between the vehicle and the mobile terminal used by the occupant, the terminal 220 can also be the mobile terminal, and at this time the call application program can be an application program deployed and running in the mobile terminal. Among them, the specific processing process of the audio files can be referred to the above embodiments, and will not be elaborated here.

[0089] The audio playback device 230 is used to play the received audio files.

[0090] It can be seen that for the in-vehicle communication system proposed in this disclosure, it is not necessary for the audio acquisition device 210 and the audio playback device 230 to have algorithm computing power. It only needs the audio acquisition device 210 and the audio playback device 230 to have the most basic functions of recording audio files and playing audio files. All processing processes are completed by the terminal 220. Therefore, the in-vehicle communication system proposed in this disclosure has lower requirements for hardware, a wider application range, and stronger universality.

[0091] Figure 3 It is a schematic diagram of an in-vehicle communication process shown according to an embodiment of the present disclosure.

[0092] As Figure 3 shown, the processing of the audio files in the method of the present disclosure mainly focuses on the call application program in the in-vehicle system, that is, the software side. On the hardware side, only the audio acquisition device and the audio playback device need to be called, and it is not necessary for these hardware to perform data processing. Thus, the audio framework of the in-vehicle system can be bypassed, and in-vehicle communication can be realized independently of the in-vehicle system audio framework.

[0093] As Figure 3As shown, when a passenger in the vehicle needs to make a call, the sound emitted by the passenger can be collected by an audio collection device. The audio collection device can send the collected mixed audio file to the software side. The software side can also obtain an environmental audio file, and process the mixed audio file and the environmental audio file to separately obtain a pure human voice component. The software side can also determine a volume compensation value based on the status information, perform volume compensation on the human voice component, send the audio file corresponding to the human voice component to an audio playback device at a specified location, and play it by this device, thereby realizing a call between two locations.

[0094] For the specific steps and links, reference can be made to the description of the method-side embodiments above, and details will not be elaborated here.
