[0002] Intelligent in-vehicle voice assistants are a core application of smart cockpits, enabling users to interact with the vehicle via voice. Leveraging cutting-edge artificial intelligence technology, these assistants endow cars with "intelligence," allowing them to better understand the driver's needs and provide services accordingly.

[0003] In related technologies, the MIC (Microphone) of an intelligent in-vehicle voice assistant transmits data through a T-BOX (Telematics BOX, a vehicle-to-everything service terminal). When the voice assistant's microphone captures a user's voice command, this voice data is processed and transmitted through the T-BOX. The T-BOX then sends this voice data to the central processing unit or cloud server of the in-vehicle infotainment system for recognition and analysis to execute corresponding commands or provide the necessary information.

[0004] However, the microphone of the voice assistant will have problems such as audio abnormality, audio distortion, constant frequency interference, and incomplete AEC (Acoustic Echo Canceller) processing when passing through T-BOX. If the software and hardware of T-BOX are modified in the future, it will affect the audio signal and greatly reduce the accuracy of speech recognition, which urgently needs to be solved. Utility Model Content

[0005] This utility model provides a voice processing system and vehicle for a vehicle, which solves the problem of low voice wake-up recognition rate caused by voice assistant MIC transmitting voice data through T-BOX.

[0011] Optionally, the voice processing device includes: a voice recognition unit connected to the noise reduction unit, which generates text information based on the noise-reduced voice data; and a voice processing unit connected to the voice recognition unit, which converts the text information into the target control command.

[0024] Figure 6 This is a block diagram of a vehicle provided according to an embodiment of the present utility model. Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] The following description, with reference to the accompanying drawings, describes a vehicle voice processing system and a vehicle according to an embodiment of the present invention. Addressing the problem mentioned in the background art where voice assistant MIC transmitting voice data via T-BOX leads to low voice wake-up recognition rates, the present invention provides a vehicle voice processing system. This system includes: multiple voice acquisition devices and a voice processing device for collecting user voice data. The multiple voice acquisition devices are respectively configured to correspond one-to-one with the vehicle seats, and the voice processing device is connected to each of the multiple voice acquisition devices. The voice processing device obtains the vehicle's target control commands based on the user's voice data. This solves the problem of low voice wake-up recognition rates caused by voice assistant MIC transmitting voice data via T-BOX, effectively ensuring audio integrity, reducing constant frequency interference, improving voice wake-up recognition rates, and facilitating subsequent modifications to the T-BOX hardware and software without affecting the audio signal.

[0027] Before introducing the embodiments of this utility model, the impact or problems caused by the T-BOX of the voice assistant MIC in the related technology will be briefly described.

[0028] Specifically, when the voice assistant's microphone transmits voice data through the T-BOX, the following problems may occur:

[0029] (1) Audio abnormality: The voice assistant needs the original audio, but what it gets in the end may be the audio after the MIC channel has been processed, which seriously affects wake-up and recognition processing;

[0030] (2) Phase difference: The phase consistency requirement for the microphone channel is less than 10 degrees for 100-2KHz. The algorithm relies on phase information. When the phase consistency is poor, the algorithm will deviate from the driver or passenger seat when making the beam. If the target voice is not in the beam, it will cause audio distortion.

[0031] (3) Constant frequency interference: The measured constant frequency interference is serious. The spectrum below 200Hz will be lost. The incomplete audio will greatly affect the algorithm processing.

[0032] (4) If this scheme is used, any subsequent changes to the T-BOX's hardware and software will directly affect the audio signal, requiring a new algorithm to be developed.

[0033] (5) Amplitude requirements: Microphone channel amplitude requirements test standard: analog microphone: 0.004-0.005, digital microphone with -26dBFS sensitivity: 0.0015;

[0034] (6) MIC1 and MIC2 are on different hosts, and the latency is difficult to guarantee, resulting in incomplete AEC processing;

[0035] (7) There will be a 20% to 30% difference in the actual vehicle test results of T-BOX in terms of wake-up and recognition indicators.

[0036] Therefore, to solve the above problems, this utility model proposes a vehicle voice processing system that uses a single microphone system. The voice assistant can obtain the original audio, ensuring audio integrity, reducing constant frequency interference, and improving voice wake-up recognition rate. Subsequent modifications to the T-BOX hardware and software are convenient and will not affect the audio signal. The following will provide a detailed description of the vehicle voice processing system of this utility model, with examples and accompanying drawings.

[0037] Specifically, Figure 1 This is a schematic diagram of the voice processing system for a vehicle provided in an embodiment of the present invention.

[0038] like Figure 1 As shown, the vehicle's voice processing system 10 includes: multiple voice acquisition devices 100 and a voice processing device 200.

[0039] Specifically, multiple voice acquisition devices 100 for collecting user voice data are respectively set up one-to-one with the seats of the vehicle; the voice processing device 200 is connected to the multiple voice acquisition devices 100 respectively, and the voice processing device 200 obtains the target control command of the vehicle based on the user voice data.

[0040] Optionally, in some embodiments, all of the multiple voice acquisition devices 100 are microphones.

[0041] Optionally, in some embodiments, none of the multiple voice acquisition devices 100 pass through the vehicle-to-everything (V2X) service terminal T-BOX.

[0042] In this embodiment of the invention, the voice acquisition device 100 is a microphone, with multiple microphones configured one-to-one with the seats of the vehicle to acquire user voice data.

[0043] Furthermore, the vehicle voice processing system 10 of this embodiment of the present invention is provided with a voice processing device 200, which receives user voice data acquired by multiple voice acquisition devices 100, and parses the user voice data to obtain the target control command of the vehicle.

[0044] The target control commands obtained in this embodiment of the invention are directly acquired through microphones that correspond one-to-one with the vehicle seats. Since the microphones in this embodiment of the invention do not go through the T-BOX, the voice assistant can obtain the original audio, thereby ensuring the integrity of the user's voice data and greatly improving the accuracy of voice recognition.

[0045] The following examples, in conjunction with the accompanying drawings, further illustrate the configuration of the vehicle voice processing system 10 according to an embodiment of the present invention.

[0046] Specifically, Figure 2This is a schematic diagram illustrating the configuration of a vehicle voice processing system according to a specific embodiment of the present invention.

[0047] like Figure 2 As shown, the voice processing device 200 specifically includes: a wireless network controller 201, a noise reduction unit 202, a voice recognition unit 203, a voice processing unit 204, and a speaker 205.

[0048] Specifically, in some embodiments, the voice processing device 200 includes: a wireless network controller 201 connected to multiple voice acquisition devices 100, used to extract voiceprint features of user voice data and determine noise data that conforms to preset noise voiceprint features based on the voiceprint features; and a noise reduction unit 202 connected to the wireless network controller 201, used to perform noise reduction operation on the noise data to obtain noise-reduced voice data.

[0049] Optionally, in some embodiments, multiple voice acquisition devices 100 are respectively disposed on the interior panel above the driver's seat, the interior panel above the passenger seat, the interior panel of the left rear door, and the interior panel of the right rear door, for collecting user voice data from multiple directions.

[0050] It should be understood that the four microphones, located in front of the driver's seat, in front of the passenger seat, on the left rear door, and on the right rear door, do not directly correspond to a standard microphone array configuration (such as a linear array, planar array, or circular array). Instead, it can be viewed as a special type of spatially distributed microphone array, where microphones are placed in different locations within the vehicle to capture sound from multiple directions.

[0051] The two front microphones are installed in the interior trim panels above the driver and passenger seats. This installation method helps capture sounds from different directions and reduces wind and road noise interference. The two rear microphones are installed in the door trim panels, especially useful when there is sufficient space in the door trim panels and it does not affect door functionality. This installation method helps capture sounds from near the doors, such as conversations between passengers or the sound of the doors closing.

[0052] Integration with other parts of the vehicle can be achieved using a microphone array module, integrating them into a single array module. The module is customized to the size and shape of the vehicle's interior space to achieve optimal sound capture. The array module contains signal processing circuitry and algorithms capable of processing and fusing sound signals from different microphones, improving the accuracy and robustness of speech recognition.

[0053] The main advantage of this spatially distributed microphone array is that it can provide sound information from all corners of the vehicle interior, facilitating more comprehensive sound capture and more accurate sound source localization. Through appropriate signal processing algorithms, the system can analyze and compare sound signals from different microphones to determine the location, direction, and distance of the sound source, thereby optimizing speech recognition performance.

[0054] Advantages of microphone arrangement: (1) Proximity to sound source: The microphone is installed close to the main sound source (the driver's or passenger's mouth) to capture sound more clearly. This helps reduce sound attenuation and distortion during propagation; (2) Avoidance of obstruction: There are no obstructions in front of the microphone, such as seat headrests, sun visors, etc., to avoid sound being blocked or reflected; (3) Distance from noise sources: The microphone is kept away from noise sources inside the vehicle, such as the engine, air conditioning vents, fans, etc., to reduce the impact of these noises on recording quality.

[0055] The two front microphones are installed in the interior trim panels above the driver and passenger seats. This installation helps capture sounds from different directions and reduces wind and road noise interference. The two rear microphones are installed in the door trim panels, which is particularly useful when there is sufficient space in the door trim panels and it does not affect door functionality. This installation helps capture sounds from near the doors, such as conversations between passengers or the sound of the doors closing.

[0056] Specifically, the wireless network controller 201 has powerful data processing capabilities and can extract voiceprint features from user voice data in real time. By comparing and analyzing voiceprint features, the wireless network controller 201 can accurately identify noise data that matches preset noise voiceprint features.

[0057] Among them, the preset noise voiceprint features are voiceprint feature templates pre-set based on common noise types (such as background noise, machine roar, etc.). These templates can be trained and optimized through machine learning algorithms to improve the accuracy and efficiency of noise recognition.

[0058] The noise reduction unit 202 is responsible for receiving noise data transmitted by the wireless network controller 201 and performing noise reduction processing on it. The noise reduction unit 202 adopts advanced noise reduction algorithms and technologies, such as adaptive filtering and spectrum subtraction, which can effectively remove interference components in noise data and retain useful information in user voice data.

[0059] Optionally, in some embodiments, the voice processing device 200 further includes a voice recognition unit 203 and a voice processing unit 204, wherein the voice recognition unit 203 is connected to multiple voice acquisition devices 100 respectively, and the voice recognition unit 203 generates text information based on the noise-reduced voice data; the voice processing unit 204 is connected to the voice recognition unit 203, and the voice processing unit 204 converts the text information into target control commands.

[0060] Optionally, in some embodiments, the voice processing device 200 further includes a speaker 205, which is connected to the voice processing unit 203 and is used to play target control commands via voice.

[0061] Specifically, such as Figure 2 As shown, the voice processing device 200 of this utility model embodiment includes a voice recognition unit 203. The voice recognition unit 203 receives noise-reduced voice data, obtains text information, and determines whether the text information is a control command. If the text information is a control command, it is further processed; otherwise, it does not return the recognition result and waits for the user to input voice data again.

[0062] Furthermore, such as Figure 2 As shown, the voice processing device 200 of this utility model embodiment includes a voice processing unit 204. When the text information is a control command, the voice processing unit 204 receives the text information and performs keyword extraction to obtain multiple keywords. It then converts the multiple keywords to obtain the final target control command and plays the target control command through the speaker 205.

[0063] It should be noted that, after initializing the voice recognition function, the vehicle voice processing system 10 of this utility model embodiment acquires the user's voice input through a separate microphone system (multiple voice acquisition devices 100), determines whether the current user's voice is a wake-up word, and if the current user's voice is a wake-up word, controls the voice processing device 200 to be woken up; otherwise, it waits for the user's voice to be input again.

[0064] Therefore, the vehicle voice processing system 10 of this utility model embodiment completely obtains the user's wake-up word, reduces constant frequency interference, greatly improves the voice wake-up rate, and enhances the user's experience.

[0065] Alternatively, in some embodiments, such as Figure 2 As shown, the vehicle's voice processing system 10 also includes a display device 400, which is connected to the voice processing device 200. The display device 400 provides a non-recognition display reminder when the voice recognition unit 203 has not generated text information.

[0066] It is understandable that when the microphone collects user voice data, situations such as the user speaking a dialect or speaking at a low volume may occur, leading to voice recognition failure. Therefore, to promptly notify the user of voice recognition failure, this embodiment of the invention includes a display device 400, such as... Figure 2 As shown, the display device 400 is connected to the voice processing device 200. If the voice recognition unit 203 fails to recognize the voice, the display device 400 can show the failure information to the user. This greatly enhances the interaction between the voice assistant and the user, improving the user experience.

[0067] It should be noted that the display device 400 in this embodiment of the present invention can be a vehicle display screen or other similar device, and is not specifically limited here.

[0068] Alternatively, in some embodiments, such as Figure 2 As shown, the vehicle's voice processing system 10 also includes a reminder device 300, which is connected to the voice processing device 200. The reminder device 300 provides a reminder when the voice recognition unit 203 has not generated text information.

[0069] It is understandable that if a driver receives a non-recognition alert via the display device 400 in the event of voice recognition failure, it could potentially pose a driving safety hazard. Therefore, to ensure safe driving and promptly alert the user to voice recognition failure, this embodiment of the invention includes an alert device 300. Figure 2 As shown, the reminder device 300 is connected to the voice processing device 200. If the voice recognition unit 203 fails to recognize the voice, the reminder device 300 can broadcast the failure information to the user. This greatly enhances the interaction between the voice assistant and the user, improving the user experience while ensuring driving safety.

[0070] It should be noted that the reminder device 300 in this embodiment of the present invention can be a car audio system, a speaker, or other similar device, and is not specifically limited here.

[0071] To enable those skilled in the art to further understand the vehicle voice processing system of this utility model embodiment, the following examples, in conjunction with the accompanying drawings, illustrate the control principle of the system.

[0072] Specifically, Figure 3 This is a flowchart illustrating the voice recognition control principle of a specific embodiment of the present invention. The voice processing system of the vehicle in this embodiment of the present invention includes the following steps when performing voice recognition control:

[0073] (1) Initialize the vehicle's voice processing system and wait for user voice input;

[0074] (2) Collect sound without going through the T-BOX’s separate microphone and determine whether it is a wake word. If the user’s voice is a wake word, the voice recognition control is activated; otherwise, wait for the user to input the voice again.

[0075] (3) Wait for user voice input, the microphone array collects the sound and processes the signal;

[0076] (4) The speech recognition system receives the signal, recognizes the user's speech, and determines whether the user's speech is a control command. If it is a control command, the system returns the recognition result; otherwise, it does not return the recognition result and waits for the user to input the voice again.

[0077] (5) Extract keywords from the returned recognition results using a speech recognition program and then convert them;

[0078] (6) Output the voice recognition result and end the process.

[0079] As can be seen from the above embodiments, in the related technical solutions, the MIC needs to go through the T-BOX, which affects the voice wake-up recognition rate. However, the vehicle voice processing system of this utility model uses a microphone to collect sound alone without going through the T-BOX, which can achieve accurate voice recognition function, ensure the integrity of audio, and subsequent hardware and software modifications to the T-BOX will not affect the audio signal.

[0080] Specifically, Figure 4 This is a schematic diagram illustrating the comparison of data between the MIC and T-BOX in a specific embodiment of the present invention, as shown below. Figure 4 As shown, after conducting real-vehicle voice testing, the results indicate that the wake-up accuracy and recognition accuracy of the microphone without a T-BOX are higher than those with a T-BOX. Therefore, the vehicle voice processing system of this invention, using only a single microphone system, effectively improves the wake-up and recognition accuracy of the voice assistant.

[0081] Figure 5 This is a schematic diagram of constant-frequency interference audio analysis of the MIC via a T-BOX according to a specific embodiment of the present invention, as shown below. Figure 5 As shown, this invention analyzes the constant-frequency interference audio of the microphone after passing through the T-BOX. When the microphone does not pass through the T-BOX, the spectrum is normal and there is no interference. However, when the microphone passes through the T-BOX, the constant-frequency interference is quite severe. Therefore, the vehicle voice processing system of this invention uses a separate microphone system, allowing the voice assistant to obtain the original audio, effectively reducing constant-frequency interference, improving voice wake-up and recognition accuracy, and enhancing the user experience.

[0082] According to the vehicle voice processing system proposed in this embodiment, multiple voice acquisition devices are respectively set up one-to-one with the vehicle seats. User voice data is collected using these multiple voice acquisition devices, and a voice processing device is connected to each of these devices. The voice processing device obtains the target control command for the vehicle based on the user voice data. This solves the problem of low voice wake-up recognition rate caused by voice assistant MIC transmitting voice data through T-BOX, effectively ensuring audio integrity, reducing constant frequency interference, improving voice wake-up recognition rate, and facilitating subsequent modifications to the T-BOX hardware and software without affecting the audio signal.

[0083] Next, the vehicle proposed according to the embodiments of this utility model is described with reference to the accompanying drawings.
