[0055] In order to make the objects, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0056] In the present application, the terms "first", "second", and the like are used to distinguish the same or similar items with substantially the same function and action, and it should be understood that there is no logical or time sequence relationship between "first", "second", and "nth", and the number and execution order are not limited.

[0057] In the present application, the term "at least one" means one or more, and the term "multiple" means two or more.

[0058] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data for analysis, stored data, displayed data, etc.) and signals involved in the present application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of related data need to comply with relevant laws, regulations and standards of relevant countries and regions. For example, the voice signal involved in the present application is obtained under sufficient authorization.

[0059] Figure 1 is a hardware structural schematic diagram of a vehicle-mounted voice processing system according to an embodiment of the present application. Referring to Figure 1 , the hardware structure of the vehicle-mounted voice processing system includes a plurality of physical keys, a microphone array, an audio processing module, a communication module, a power amplifier module, a vehicle-mounted loudspeaker, and a control system.

[0060] For example, the plurality of physical buttons 101 are used to control the microphone array 102, and the plurality of physical buttons 101 are connected with the microphone array 102. The microphone array 102 is used to collect voice to obtain voice signals, and the microphone array 102 includes a plurality of microphones, and the microphone array 102 is connected with the audio processing module 103. Single or multiple microphones closer to the driver are selected by the plurality of physical buttons 101, voice control or system settings to collect voice input, so as to improve the effect of voice recognition and Bluetooth call. The single, double or multiple microphones are controlled by the single press, long press or double click of the plurality of physical buttons 101 to collect voice signals, so as to improve the effect of voice recognition and Bluetooth call.

[0061] The audio processing module 103 is used to perform voice processing on the voice signals to obtain processed voice signals, and the audio processing module 103 is connected with the communication module 104. The audio processing module 103 includes an audio noise reduction module 1031 and a DSP decoding module 1032, and the DSP decoding module 1032 can be directly connected with the power amplifier module 105. The audio noise reduction module 1031 compares or captures the sound in the environment, digitizes and encodes it into an electrical signal, then uses analysis and processing algorithms to separate the voice and noise, and eliminates noise and echo, so as to output single, double or multiple digital voice signals with high quality and annoying noise reduction. The voice processing is realized by the DSP decoding module 1032. The voice processing includes voice recognition, language understanding, voice synthesis, voice enhancement and voice data compression, etc. Among them, the voice recognition is to extract the feature parameters of the voice signal to be recognized in real time, and match with known voice samples, so as to determine the phoneme attribute of the voice signal to be recognized. The voice recognition method includes statistical pattern voice recognition, structure and sentence pattern voice recognition, etc. The above method can obtain important parameters such as formant frequency, pitch, voice and noise. Voice understanding is the theoretical and technical basis for people and computers to communicate in natural language. The main purpose of voice synthesis is to enable computers to speak. Through decoding, the voice signal collected by the microphone can be restored into a high-guaranteed analog audio signal output to the power amplifier module 105.

[0062] The communication module 104 is configured to send the processed voice signal to other devices and receive voice signals sent by other devices, and the communication module 104 is connected with the power amplifier module 105. The power amplifier module 105 is configured to amplify the received voice signal to obtain an amplified voice signal, and the power amplifier module 105 is connected with the vehicle-mounted loudspeaker 106. For example, the high-pitched, medium-pitched and low-pitched analog audio signals restored by the DSP decoding module 1032 are amplified by the power amplifier module 105 and output to the vehicle-mounted loudspeaker 106. The vehicle-mounted loudspeaker 106 is configured to play the amplified voice signal. That is, the high-pitched, medium-pitched and low-pitched signals amplified and restored by the power amplifier module 105 are output to the vehicle-mounted loudspeaker 106. In addition, the SOC control module 107 is configured to switch and control the voice system function and the multimedia function mode. The power supply module 108 is configured to provide stable and reliable power supply for each part of the system.

[0063] Figure 2 A flowchart of a vehicle-mounted voice processing method is provided according to an embodiment of the present application. The method is executed by a vehicle-mounted voice processing system, which includes a microphone array, an audio processing module and a communication module. Referring to Figure 2 , the method includes the following steps:

[0064] 201. Collecting voice through the microphone array to obtain a plurality of first voice signals, the microphone array including a plurality of microphones, the plurality of first voice signals corresponding to the plurality of microphones one by one, and the microphone array being connected with the audio processing module.

[0065] In the embodiment of the present application, the microphone array refers to a recording system composed of two or more microphones. For example, a microphone array composed of four microphones is used. The four microphones are arranged at the front left position, the front right position, the rear left position and the rear right position in the vehicle, respectively. By uniformly arranging a plurality of microphones, a better voice collection effect can be obtained. After four first voice signals are collected through the microphone array, the four first voice signals are sent to the audio processing module for voice processing.

[0066] 202. Voice processing the plurality of first voice signals through the audio processing module to obtain a second voice signal, the second voice signal being a voice signal of a target sound source object, and the target sound source object being a sound source object for voice communication through the microphone array, and the audio processing module being connected with the communication module.

[0067] In the embodiment of the present application, the audio processing module is used to receive the multiple voice signals sent by the microphone array and perform voice processing thereon. The voice processing includes noise reduction processing, voice recognition, voice understanding, voice synthesis, voice enhancement, voice data compression, etc., which are not limited in the embodiment of the present application. The second voice signal is used to indicate the voice of the clear target sound source object in the first voice signal. By separating the second voice signal and transmitting it to the communication terminal, the interference of other noise signals can be excluded, and the quality of the vehicle-mounted voice call can be improved.

[0068] 203. Transmitting the second voice signal to the communication terminal of the target sound source object through the communication module.

[0069] In the embodiment of the present application, the communication terminal can be wirelessly connected to the terminal where the vehicle-mounted voice processing system is located through Bluetooth. After receiving the second voice signal sent by the audio processing, the communication module transmits it to the communication terminal, and the communication terminal transmits the voice signal to the call opposite end, thereby realizing the vehicle-mounted voice call.

[0070] The embodiment of the present application provides a vehicle-mounted voice processing method. Through the vehicle-mounted voice processing system composed of a microphone array, an audio processing module, a communication module and the like, the voice signal related to the target sound source object in the process of the vehicle-mounted voice call can be automatically selected. Compared with the traditional scheme of fixedly using a single microphone to collect the voice signal in the vehicle, the present scheme can improve the quality of the vehicle-mounted voice collection, and further improve the accuracy of the vehicle-mounted voice recognition. Accordingly, the present scheme can not only improve the intelligent level of the vehicle, but also improve the user's use experience and satisfaction.

[0071] Figure 3 is a flowchart of another vehicle-mounted voice processing method provided by the embodiment of the present application. The method is executed by a vehicle-mounted voice processing system, see Figure 3 , which comprises the following steps:

[0072] 301. Collecting voice through a microphone array to obtain multiple first voice signals. The microphone array comprises multiple microphones, and the multiple first voice signals correspond to the multiple microphones one by one. The microphone array is connected with an audio processing module.

[0073] In the embodiment of the present application, the microphone array refers to a recording system composed of two or more microphones. For example, a microphone array composed of four microphones is used. The positions of the four microphones in the vehicle are left front, right front, left rear and right rear respectively. By uniformly arranging multiple microphones, a better voice collection effect can be obtained. The number, position and architecture of the multiple microphones in the microphone array are not limited in the embodiment of the present application.

[0074] It should be noted that the vehicle-mounted voice processing system can control the microphone array to switch to a multi-microphone working mode, that is, support multiple microphones to collect voice at the same time. At this time, multiple voice signals can be collected through the microphone array. The vehicle-mounted voice processing system can also control the microphone array to switch to a single-microphone working mode, that is, only support a single microphone to collect voice. At this time, only a single voice signal can be collected through the microphone array. The embodiments of the present application do not limit this.

[0075] For example, it is assumed that the vehicle-mounted voice processing system is in a multi-microphone working mode, and voice is collected through four microphones at the same time. The voice in the vehicle cabin is collected through the left front microphone, the right front microphone, the left rear microphone, and the right rear microphone to obtain four first voice signals. The four first voice signals are sent to the audio processing module for voice processing.

[0076] In the embodiments of the present application, voice is collected in the above manner to obtain multiple voice signals, which facilitates subsequent voice processing of the multiple voices. Compared with voice processing based on only a single voice, the background noise and echo interference can be more comprehensively and reliably eliminated, the voice clarity and audibility can be improved, and the accuracy and robustness of voice recognition can be improved.

[0077] In some embodiments, the driver or passenger can turn on or turn off multiple microphones in the microphone array by controlling physical buttons or voice control to meet various scene requirements. The following mode A and mode B are described by taking the driver or passenger controlling the microphone to start collecting voice as an example. It should be noted that the driver or passenger controls the microphone to turn off or controls the microphone array to switch the working mode, and the same applies here, which will not be described again.

[0078] Mode A: The driver or passenger controls the physical button. Correspondingly, the vehicle-mounted voice processing system further includes multiple physical buttons, and the multiple physical buttons are used to control the microphone array, and the multiple physical buttons correspond to the multiple microphones one by one.

[0079] Optionally, in a case where the vehicle-mounted voice processing system is in a multi-microphone working mode, the vehicle-mounted voice processing system determines at least two microphones that are working; in response to a triggering operation of the first physical button by the driver or passenger, voice is collected through the at least two microphones and the microphone corresponding to the first physical button to obtain multiple voice signals. The multi-microphone working mode is used to indicate that the vehicle-mounted voice processing system supports multiple microphones to collect voice at the same time, and the first physical button is a physical button corresponding to a microphone other than the at least two microphones.

[0080] For example, the in-vehicle voice processing system is in a multi-microphone working mode, such as the left rear microphone and the right rear microphone are working. At this time, the physical buttons corresponding to the left front microphone and the right front microphone are the first physical buttons. When the driver triggers the physical buttons corresponding to the left front microphone and the right front microphone, the in-vehicle voice processing system turns on the above two microphones. At this time, the in-vehicle voice processing system controls the original left rear microphone and the right rear microphone, and the newly added left front microphone and the right front microphone to simultaneously collect the voice in the vehicle cabin.

[0081] Optionally, in the case that the in-vehicle voice processing system is in a single-microphone working mode, the in-vehicle voice processing system determines the single microphone that is working; in response to the triggering operation of any second physical button by the driver, the voice is collected through the microphone corresponding to the second physical button to obtain a single voice signal; or in response to the triggering operation of at least two second physical buttons by the driver at the same time, based on the priority of the at least two second physical buttons, the voice is collected through the microphone corresponding to the second physical button with the highest priority to obtain a single voice signal. The single-microphone working mode is used to indicate that the in-vehicle voice processing system only supports a single microphone to collect voice, and the second physical button is the physical button corresponding to the microphone other than the single microphone.

[0082] For example, the in-vehicle voice processing system is in a single-microphone working mode, such as only the left rear microphone is working. At this time, the physical buttons corresponding to the right rear microphone, the left front microphone and the right front microphone are the second physical buttons. When the driver triggers the physical button corresponding to the left front microphone, the in-vehicle voice processing system turns off the original left rear microphone and turns on the left front microphone. At this time, the in-vehicle voice processing system only controls the newly added left front microphone to collect the voice in the vehicle cabin. Alternatively, when the driver triggers the physical buttons corresponding to the left front microphone and the right front microphone at the same time, the in-vehicle voice processing system turns off the original left rear microphone and determines the priority relationship of the left front microphone and the right front microphone, that is, the priority relationship of the physical buttons corresponding to the above two microphones. For example, when the left front microphone has a higher priority, the in-vehicle voice processing system only controls the newly added left front microphone to collect the voice in the vehicle cabin.

[0083] It should be noted that the priority relationship can be set by default by the system or by the driver, and the embodiments of the present application do not limit this. For example, the system defaults that the left front microphone closer to the main driver seat has the highest priority, and the right front microphone closer to the co-driver seat has the second highest priority.

[0084] Optionally, the in-vehicle voice processing system can be controlled by the driver. Correspondingly, the in-vehicle voice processing system can recognize the voice of the driver and control a specific microphone.

[0085] Optionally, the audio processing module is configured to perform semantic recognition on the collected voice signals, and the semantic recognition is configured to determine whether the voice signals contain target instructions, and the target instructions are configured to instruct to turn on the microphones in the microphone array; in a case where the plurality of first voice signals contain target instructions, at least one target microphone corresponding to the target instructions is determined based on at least one microphone identifier in the target instructions, and different microphones in the microphone array correspond to different microphone identifiers; and the audio processing module is configured to collect voice through the at least one target microphone to obtain at least one voice signal.

[0086] For example, the voice of the occupant contains instructions such as "turn on the left front microphone" or "turn on the driver's seat microphone and the passenger's seat microphone". The audio processing module is configured to perform semantic recognition on the voice of the occupant to determine that the voice signal contains target instructions. The audio processing module is configured to determine that the microphone identifier in the target instructions is "left front microphone" or "driver's seat microphone" and "passenger's seat microphone". The vehicle-mounted voice processing system is configured to turn on the corresponding microphone and control the microphone to collect voice in the vehicle cabin.

[0087] In the embodiments of the present application, through the above-mentioned multiple ways, the occupant can adjust the state of the multiple microphones at any time according to the needs through simple and intuitive operations, so as to meet the needs of various complex scenes. For example, in the long-distance driving scene, the driver can only turn on the microphone at the driver's seat to perform voice navigation or answer the phone, while turning off the microphones at other positions to reduce the interference of background noise. Or, in the scene of the passenger making a voice call in the vehicle, the passenger can only turn on the microphone at his own position while turning off the microphones at other positions to ensure the clarity and privacy of the voice call. It should be noted that the occupant can also use the software control system in the vehicle to access the setting options of the microphone array, and select to turn on or turn off the specific microphone to adapt to the current use scene. The embodiments of the present application will not be described again.

[0088] 302、In a case where the voice of the plurality of sound source objects is collected, the audio processing module is configured to determine a target sound source object from the plurality of sound source objects, and the target sound source object is a sound source object making a voice call through the microphone array, and the audio processing module is connected with the communication module.

[0089] In the embodiments of the present application, the sound source object usually refers to the occupant. After the audio processing module receives the plurality of first voice signals sent by the microphone array, if it is detected that the plurality of first voice signals contain the sound of the plurality of sound source objects, the vehicle-mounted voice processing module determines the target sound source object from the plurality of sound source objects, so as to facilitate subsequent reduction of the interference of the voice of other sound source objects on the voice of the target sound source object, and improve the use experience and satisfaction of the occupant.

[0090] Generally, the target sound source object is determined in any one of the following manners. Here, the vehicle to which the vehicle-mounted voice processing system belongs accesses a multi-person online conference. At this time, each occupant in the vehicle can be a sound source object. The vehicle-mounted voice processing system detects the sound in the vehicle in real time, and when multiple sound source objects emit sound, the target sound source object is determined in any one of the following manners.

[0091] Manner one: the voice duration of each sound source object in the multiple sound source objects is determined by the audio processing module; and the sound source object with the longest voice duration is determined as the target sound source object.

[0092] The voice duration can be represented by the total duration of continuous sound emission, or by the proportion of the sound emission duration within a certain duration (e.g., per second). For example, the person at the main driving position speaks in the multi-person online conference, and the person at the co-driver position emits sound briefly. The vehicle-mounted voice processing system determines the person at the main driving position as the target sound source object and preferentially retains or enhances the voice signal thereof.

[0093] Manner two: the voice feature parameters of each sound source object in the multiple sound source objects are determined by the audio processing module; and the sound source object corresponding to the voice feature parameters existing in the feature database is determined as the target sound source object. The feature database is used to store the voice feature parameters of pre-recorded voice signals.

[0094] The voice feature parameters of each sound source object are not completely the same and include voiceprint features, tone features, pitch features, and speech rate features, etc. The feature database can be automatically generated according to historical call records, or generated from voice samples pre-recorded by the participants. For example, the vehicle-mounted voice processing system identifies that the voice feature parameters of a certain sound source object in the vehicle match the voice feature parameters of a historical participant pre-recorded in the feature database, while the feature parameters of other sound source objects cannot be matched with the feature database. At this time, the sound source object is determined as the target sound source object.

[0095] Manner three: the position of each sound source object in the multiple sound source objects is determined by the audio processing module; and the sound source object at the preset position is determined as the target sound source object.

[0096] The preset position can be a specific position directly set, or a position with higher priority. For example, the positions of the sound source objects in the vehicle are usually fixed, including the main driving position, the co-driver position, and the rear seat position, etc. The priority of the above multiple positions can be pre-set by the vehicle voice processing system. For example, when the person at the main driving position and the person at the co-driver position emit sound at the same time, the person at the main driving position is determined as the target sound source object by the vehicle-mounted voice processing system because the priority of the main driving position is higher.

[0097] 303、determine distances between the microphones and the target sound source object corresponding to the plurality of first voice signals respectively by the audio processing module.

[0098] In the embodiments of the present application, after the target sound source object is determined, the vehicle-mounted voice processing system calculates the distances between the plurality of microphones in the microphone array that collect voice and the target sound source object, so as to facilitate subsequent determination of a specific voice signal for voice communication from the plurality of first voice signals based on the distances, and improve the quality of voice communication. Optionally, the vehicle-mounted voice processing system analyzes the plurality of first voice signals through a pre-configured sound source positioning algorithm. The position of the target sound source object is determined through the waveform, frequency, phase and other characteristics of the plurality of first voice signals, and then the distances between the microphones and the target sound source object are determined. Correspondingly, the phase difference, time difference or intensity difference between the plurality of first voice signals is calculated by the audio processing module, so as to determine the position and distance of the target sound source object.

[0099] 304、determine a second voice signal from the plurality of first voice signals by the audio processing module, the distance between the microphone corresponding to the second voice signal and the target sound source object is less than the distance between the microphone corresponding to other voice signals and the target sound source object, and the other voice signals are voice signals other than the second voice signal.

[0100] In the embodiments of the present application, since the second voice signal is a voice signal collected by a microphone with a shorter distance to the target sound source object, the voice signal contains less noise and distortion, and the voice signal contains higher voice clarity of the target sound source object. For example, in a vehicle-mounted conference scene or a vehicle-mounted voice control scene, by selecting a voice signal collected by a microphone with a shorter distance to the target sound source object, the vehicle-mounted voice processing system can more accurately recognize the voice content of the target sound source object, thereby providing more accurate and personalized services and improving the user experience. It should be noted that in the case of collecting the voice of a single sound source object, the sound source object is directly determined as the target sound source object, and the subsequent operations and steps 303 to 304 are the same, and will not be described here.

[0101] 305、based on the other voice signals, perform voice processing on the second voice signal by the audio processing module to obtain an optimized second voice signal, the optimized second voice signal being a voice signal of the target sound source object after filtering out noise signals, the noise signals including voice signals of other sound source objects, environmental noise signals and echo signals, and the other sound source objects being sound source objects other than the target sound source object in the plurality of sound source objects.

[0102] In the embodiment of the present application, the second voice signal not only includes the voices of multiple sound source objects, but also includes environmental noise and echo, etc. In order to further improve the quality of the second voice signal, the audio processing module distinguishes the voice signal of the target sound source object from the second voice signal and retains it, while eliminating other interference signals. The environmental noise includes wind noise, tire noise, engine noise, etc., and the echo includes the echo generated by the voice played by the loudspeaker and the echo generated by the sound source object, etc.

[0103] Optionally, the vehicle-mounted voice processing system uses a beamforming technique to enhance the signal in the direction of the target sound source object, while suppressing the noise in other directions. Alternatively, the vehicle-mounted voice processing system adopts a blind source signal separation algorithm to separate the mixed voice signals of multiple sound source objects, thereby extracting the voice signal of the target sound source object. At this time, since most of the interference signals in the second voice signal are removed, only the clear voice of the target sound source object is retained, therefore, the signal intelligibility and the intelligibility of the optimized second voice signal are both better than those of the original second voice signal, and the optimized second voice signal can also provide more accurate and reliable data support for subsequent voice processing. The intelligibility is also referred to as speech intelligibility, and the intelligibility is used to indicate the percentage of the voice signal that can be understood by the user through the sound transmission system.

[0104] 306. The second voice signal is sent to the communication terminal of the target sound source object through the communication module.

[0105] In the embodiment of the present application, the communication terminal can be wirelessly connected to the vehicle where the vehicle-mounted voice processing system is located through Bluetooth. After receiving the second voice signal sent by the audio processing, the communication terminal sends the second voice signal to the communication terminal through the communication module, and sends the voice signal to the communication terminal through the communication terminal, thereby realizing the vehicle-mounted voice communication.

[0106] For example, the communication terminal is a mobile phone. In the vehicle-mounted voice communication scenario, there is long-distance communication between the mobile phone and the communication terminal, and there is Bluetooth transmission between the mobile phone and the vehicle where the vehicle-mounted voice processing system is located. At this time, the vehicle-mounted voice processing system collects the voice through the microphone array, and then processes the voice to obtain a clear voice signal. The vehicle sends the voice signal to the mobile phone through the vehicle-mounted voice processing system, and the mobile phone sends the voice signal to the communication terminal through long-distance communication technology. Correspondingly, when the mobile phone receives the voice signal sent by the communication terminal, the mobile phone sends the voice signal to the vehicle where the vehicle-mounted voice processing system is located through Bluetooth transmission, so that the voice signal is played through the vehicle-mounted loudspeaker in the vehicle-mounted voice processing system. Through the above-mentioned manner, long-distance communication between the user in the vehicle and the user of the communication terminal can be realized in the vehicle-mounted voice communication scenario.

[0107] The embodiment of the present application provides a vehicle-mounted voice processing method, through a vehicle-mounted voice processing system composed of a microphone array, an audio processing module, a communication module and the like, a voice signal related to a target sound source object in a voice call process can be automatically selected. Compared with a single microphone used for collecting the voice signal in the vehicle in the prior art, the present application can improve the quality of the vehicle-mounted voice collection, and further improve the accuracy of the vehicle-mounted voice recognition. Accordingly, the present application can not only improve the intelligent level of the vehicle, but also improve the user experience and satisfaction.
