[0038] This embodiment provides a voice packet switching method running on an electronic device. Figure 1 This is a flowchart of a voice packet switching method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0039] Step S12: Obtain the first location of the vehicle, wherein the first location is within a first region;

[0040] Step S14: In response to determining that the vehicle has left the first region through the first location, obtain the second location of the vehicle, wherein the second location is within the second region;

[0041] Step S16: Determine the target speech packet based on the second location, wherein the target speech packet is generated based on the speech features corresponding to the second region;

[0042] Step S18: Switch the initial voice packet of the vehicle system to the target voice packet, wherein the initial voice packet is generated based on the speech features corresponding to the first region.

[0043] For example, the vehicle's initial position, i.e., the first position, is obtained, which is located within a pre-defined first region. When the vehicle leaves the first region, its current position, i.e., the second position, is obtained, which is located within a second region. That is, when the vehicle's location changes, a target voice package is determined based on the vehicle's current location. This target voice package represents a voice package generated using speech synthesis technology, incorporating the speech characteristics (i.e., local dialect) corresponding to the current location, as well as the user's personalized voice features. The initial voice package set by the vehicle's infotainment system when the vehicle was in its initial position is then switched to the target voice package.

[0044] Vehicle location can be determined using positioning technologies. Common positioning technologies include: Global Positioning System (GPS): This uses satellite signals to determine a vehicle's location and is widely used in navigation, mapping, aviation, and maritime fields. Regional positioning technologies: These include wireless Fidelity (WiFi) positioning, Bluetooth positioning, and Radio Frequency Identification (RFID) positioning, which can achieve positioning indoors or in dense buildings. Inertial navigation technology: This uses sensors such as accelerometers and gyroscopes to measure the acceleration and angular velocity of an object, thereby calculating the vehicle's position. Visual positioning technology: This uses devices such as cameras or laser scanners to capture images or 3D data of the vehicle, thereby determining its position. Ultrasonic positioning technology: This uses the transmission and reception of ultrasonic signals to measure the distance between the vehicle and sensors, thereby determining the object's position. Other positioning technologies include geomagnetic positioning, topographic mapping positioning, radio positioning, and various other technologies. The appropriate positioning technology can be selected based on specific needs.

[0045] Different regions can be divided according to latitude and longitude coordinates. For example, a region can be divided into areas with longitude intervals of 5° or latitude intervals of 10°. In particular, the same region corresponds to the same speech characteristics, that is, the same local dialect is spoken within the same region.

[0046] In another embodiment, different regions can be divided by administrative areas within a country or region. For example, if the current location of the vehicle is within the city of Xi'an, then the speech packet can be determined to be generated based on the local dialect of Xi'an.

[0047] Based on the above steps, the technical solution involves obtaining a first location of the vehicle, wherein the first location is within a first region; in response to determining that the vehicle has left the first region using the first location, obtaining a second location of the vehicle, wherein the second location is within a second region; determining a target voice package based on the second location, wherein the target voice package is generated based on the speech features corresponding to the second region; and switching the initial voice package of the vehicle system to the target voice package, wherein the initial voice package is generated based on the speech features corresponding to the first region. This achieves the technical effect of generating a unique voice package for the user based on their daily conversations with the vehicle system, and automatically switching to the corresponding regional voice package based on the vehicle's location. This provides personalized and intelligent voice interaction for the vehicle system, thereby solving the technical problems of lacking personalized customization options and insufficient intelligent perception of geographical location in related technologies.

[0048] Optionally, the method further includes step S15, which specifically includes performing the following steps:

[0049] Step S151: Obtain voice audio data, wherein the voice audio data is used to record the user's speech content;

[0050] Step S152: Extract features from the speech audio data to obtain speech features;

[0051] Step S153: Generate a target speech packet set based on speech features, wherein the target speech packet set includes speech packets corresponding to different regions.

[0052] For example, voice audio data is acquired through the vehicle's infotainment system. This voice audio data records the dialogue between the user and the infotainment system, or between users themselves. Feature extraction is then performed on the acquired voice audio data to obtain the voice features of the spoken content, and a personalized target voice package is generated accordingly. This target voice package set includes voice packages corresponding to the user's geographical location and incorporating the user's personalized voice characteristics; that is, a set of local dialect voices that integrate the user's personalized voice characteristics.

[0053] Optionally, in step S152, feature extraction of the speech audio data to obtain speech features includes performing the following steps:

[0054] Step S1521: Extract features from the speech audio data to obtain prosodic features;

[0055] Step S1522: Convert the speech audio data into text to obtain the target text;

[0056] Step S1523: Extract features from the target text to obtain accent features.

[0057] For example, speech features include prosodic features and personalized spoken language features.

[0058] The in-vehicle infotainment system extracts unique prosodic features from the acquired voice audio data, such as tone, speech rate, and intonation. These prosodic features are influenced by individual language habits, cultural background, and emotional state, resulting in unique characteristics in each person's voice. Some people may speak quickly and rhythmically, others slowly with noticeable pauses, and still others with a high-pitched and expressive voice. Personalized voice customization can be provided based on these individual prosodic features.

[0059] The methods for feature extraction from speech audio data depend on the specific application scenario and data format, and no specific restrictions are imposed here. For example, frequency domain analysis methods, such as short-time Fourier transform and autocorrelation function methods, or time domain analysis methods, such as pitch period detection and cross-correlation function methods, can be used to extract pitch features. Speech rate features can be extracted by calculating the short-time energy or short-time zero-crossing rate of the speech signal. Fundamental frequency extraction methods include fundamental frequency estimation algorithms based on autocorrelation functions and fundamental frequency estimation algorithms based on short-time Fourier transforms; and vocal tract parameter extraction methods, such as linear predictive analysis, can be used to extract pitch features.

[0060] Furthermore, speech audio data can be converted into text to obtain the target text. For example, a speech recognition engine can be used to convert speech data into text. Alternatively, a natural language processing model (such as a deep learning model, recurrent neural network, etc.) can be used to process the speech data and convert it into text. Or, open-source speech-to-text libraries can be used for speech conversion. Alternatively, a speech-to-text model can be built and trained independently according to specific needs to achieve more accurate conversion results. These methods allow for the selection of appropriate models and algorithms for speech-to-text conversion based on specific application scenarios and requirements.

[0061] After analysis and processing, feature extraction is performed on the target text to extract the user's personalized accent features. This allows the synthesized target speech package to include redundant words, interactivity, and modal particles, making the target speech package more in line with the user's speaking habits and sound more approachable and interesting. For example, the frequent use of conjunctions such as "then," "so," and "because" or modal particles such as "ah," "oh," "ba," and "ya" in the conversation can all be reflected in the target text and then extracted and integrated into the target speech package.

[0062] Optionally, in step S153, generating the target speech packet set based on speech features includes performing the following steps:

[0063] Step S1531: Obtain the speech feature set, wherein the speech feature set includes speech features corresponding to different regions;

[0064] Step S1532: Generate a target speech packet set based on speech features and speech feature set.

[0065] For example, the speech feature set is a set of dialects corresponding to different regions. That is, after obtaining the language packs of multiple dialects, the speech features extracted from the speech audio data are integrated into the speech packs of multiple dialects through speech synthesis technology. The resulting target speech pack set is the user-personalized speech pack set based on the geographical location.

[0066] Optionally, in step S15, the method further includes step S154: displaying prompt information in the graphical user interface of the vehicle system, wherein the prompt information is used to indicate that the target voice package set has been generated.

[0067] Once the target voice package set is generated, a notification message indicating completion will be displayed to the user through the vehicle's graphical user interface. The user can easily receive the notification message on the graphical user interface, allowing them to promptly check whether the generated target voice package set meets expectations, thus enabling continuous optimization of the vehicle's voice packages.

[0068] Optionally, in step S154, the method further includes at least one of the following:

[0069] Step S1541: In response to receiving the confirmation command, import the target voice packet set into the preset storage location;

[0070] Step S1542: In response to receiving the modification instruction, update the target speech packet set.

[0071] After the user sees the prompt message on the graphical interface of the vehicle system, they can view the generated target voice package set. When the user is satisfied with the generated target voice package set, they can issue a confirmation command by clicking the confirmation button on the graphical user interface. After receiving the confirmation command, the vehicle system will import the generated target voice package into the pre-set storage location so that when the vehicle location is changed in the future, the target voice package corresponding to the current vehicle location can be obtained in a timely manner.

[0072] When a user is not satisfied with the generated target voice package set, they can issue a modification command by clicking the modification button on the graphical user interface. Upon receiving the modification command, the vehicle system updates the target voice package set. This involves reacquiring the voice audio data, extracting the voice features from the voice audio data, and regenerating the target voice package set based on the voice features and the speech feature set.

[0073] Optionally, in step S15, the method further includes updating the target speech packet set based on the user's speech content.

[0074] For example, voice audio data is not static; users' speaking habits change with factors such as age and location, and the vehicle's driver may also change. Therefore, the in-vehicle infotainment system needs to continuously monitor the voice audio data in the vehicle and update the target voice package set in a timely manner. Once a user's speaking habits or accent change, the system can automatically adjust the target voice package set to ensure that voice interaction always maintains the best personalized experience.

[0075] Furthermore, in accordance with relevant requirements, the voice package switching method also includes user data privacy protection to ensure the security and privacy of user voice data, including measures such as data encryption and anonymization. For example, before acquiring the user's voice audio data, a pop-up window appears on the vehicle's graphical user interface, requesting the user's permission to collect audio. Simultaneously, user feedback on the voice interaction function is collected, including satisfaction with the voice package and the accuracy of voice package switching when the user's location changes, in order to continuously optimize the system's performance.

[0076] In a specific embodiment, Xiaoming is driving his car from Beijing to a tourist attraction in Zhangjiakou City, Hebei Province. When Xiaoming's vehicle enters Zhangjiakou City, the in-vehicle system senses the change in location and automatically switches to a Zhangjiakou dialect voice pack. It has already recorded and analyzed Xiaoming's daily conversations with the system, including his unique voice characteristics. Based on Xiaoming's voice features, the system automatically generates a personalized voice pack incorporating Zhangjiakou dialect, for example: "Hello Mr. Xiaoming! Welcome to Zhangjiakou City. Which attraction are you going to?" Xiaoming is surprised and happy to hear the system use his own voice combined with Zhangjiakou dialect for this voice prompt. This personalized and localized voice interaction experience meets user expectations and enhances user trust and satisfaction with the in-vehicle system.

[0077] Figure 2 This is a schematic diagram of a voice packet switching method according to an embodiment of the present invention, such as... Figure 2As shown, the vehicle's infotainment system first records daily conversations, acquiring voice audio data. After analyzing the voice audio data, it extracts voice features and then generates voice packages based on these features, which are then fed back to the user for settings (confirmation or modification). Finally, it obtains the vehicle's current location. When the vehicle's location changes and moves outside the preset area, it switches to the voice package corresponding to the current location; if the vehicle's location does not change or it has not moved outside the preset area, it retains the original voice package. In addition, the vehicle's infotainment system continuously monitors the voice audio data in the vehicle and updates the target voice package set in a timely manner.

[0078] Figure 3 This is a timing diagram of a voice packet switching method according to an embodiment of the present invention, such as... Figure 3 As shown, the vehicle and user begin their daily conversations. The vehicle records these conversations, storing the voice and audio data in the vehicle's infotainment system, and analyzes the content. Voice features are extracted from the infotainment system to generate voice packets. Once generated, a prompt message is sent to the user, who can then confirm or modify the generated voice packet and set it in the vehicle. The vehicle's location is determined using positioning technology. When the vehicle reaches a different location (i.e., a change in geographical location), the system switches to the voice packet corresponding to that location. Simultaneously, the voice packets are updated in real-time to continuously optimize system performance.

[0079] This feature integrates the user's personalized voice into the voice interaction and intelligently switches languages ​​based on the region, providing a more personalized and considerate voice interaction experience, further enhancing user satisfaction and overall user experience. By offering voice prompts and interactions that conform to local language habits, the system helps drivers obtain information more conveniently, improving driving safety and comfort. Especially in different regions or language environments, drivers can understand voice prompts more quickly, reducing distractions.

[0080] In this embodiment of the invention, by obtaining a first location of the vehicle, wherein the first location is within a first region; in response to determining that the vehicle has left the first region through the first location, obtaining a second location of the vehicle, wherein the second location is within a second region; determining a target voice package based on the second location, wherein the target voice package is generated based on the speech features corresponding to the second region; and switching the initial voice package of the vehicle system to the target voice package, wherein the initial voice package is generated based on the speech features corresponding to the first region, the technical solution achieves the technical effect of generating a unique voice package for the user based on the user's daily dialogue with the vehicle system, and automatically switching to the voice package of the corresponding region based on the vehicle's location. This provides personalized and intelligent voice interaction for the vehicle system, thereby solving the technical problems of lacking personalized customization options and insufficient intelligent perception of geographical location in related technologies.
