These systems often operate independently, lacking effective integration and coordination mechanisms, resulting in low communication efficiency and difficulty in achieving unified voice control and interaction. In addition, due to the differences in interfaces and protocols between systems, the processing and transmission of voice signals become complex, making it difficult to achieve high-quality voice communication. At the same time, the lack of effective voice recording and historical voice tracing functions also limits the analysis and review of communication history.

[0044] It should be noted that the present invention relates to a multi-system voice fusion method for aerospace, and the core of this method is to unify multiple communication methods in the aerospace voice communication system and access them to the voice fusion processing workstation for processing. The voice fusion processing workstation mentioned here refers to a device integrated with multiple voice processing functions, which can receive, process, and schedule voice signals from different communication systems.

[0045] Specifically, the workstation includes a voice communication module, a voice processing module, a voice control module, a voice recording module, and a voice interaction module. These modules work together to achieve the comprehensive processing and scheduling of voice signals. For example, the voice communication module can be connected to different communication systems through various audio interfaces such as network ports, U ports, serial ports, and telephone ports, while the voice processing module is responsible for performing operations such as digital-to-analog conversion, encoding and decoding, resampling, and noise suppression to ensure the quality and compatibility of voice signals.

These modules together constitute a complete system for realizing efficient voice communication inside the spacecraft and between the spacecraft and the ground. Among them, the voice communication module refers to the part responsible for connecting and communicating with existing voice communication systems and voice fusion communication clients.

[0055] Specifically, the voice communication module can be configured with multiple interfaces, such as network ports, U ports, serial ports, telephone ports, etc., to adapt to different types of communication links. These interfaces can be connected to systems such as shortwave communication, ultra-shortwave communication, microwave communication, Ethernet communication, and analog telephone communication. The voice processing module is responsible for comprehensively processing the voice signals of multiple systems received, including but not limited to digital-to-analog conversion, encoding and decoding, resampling, noise suppression, and mixing processing. The voice control module is used to schedule multiple voice signals and perform corresponding processing according to control signals.

[0056] Preferably, the voice recording module can be designed to have high-capacity storage to record and store a large number of voice files. This module can be set to automatically record all communication sessions, or start recording according to specific trigger conditions (such as the recognition of specific keywords). The voice interaction module can integrate advanced voice recognition technologies, such as deep learning algorithms, to improve the accuracy and response speed of voice control.

[0057] Furthermore, the module can also include a speech synthesis function for generating voice feedback or warning messages. To improve the flexibility and scalability of the system, a modular design can be considered, enabling each module to be upgraded or replaced as needed.

[0058] In some embodiments, as Figure 3 shown. The voice fusion communication client is installed on the spacecraft cabin computer and connected to the voice fusion processing workstation via high-speed Ethernet. Each client has the functions of password login, voice communication between clients, voice communication between space and ground, voice communication with extravehicular personnel, voice communication with program-controlled telephones, voice recording, speech recognition, and speech synthesis.

[0059] It should be noted that this embodiment mode details the functions and installation locations of the voice fusion communication client. The voice fusion communication client is software installed on the spacecraft cabin computer, which is connected to the voice fusion processing workstation via high-speed Ethernet. The client has various functions, including password login, voice communication between clients, voice communication between space and ground, voice communication with extravehicular personnel, voice communication with program-controlled telephones, voice recording, speech recognition, and speech synthesis. Here, voice communication between space and ground refers to the communication from the spacecraft to the ground control center, and voice communication with extravehicular personnel refers to the communication between the cabin crew and the personnel performing tasks outside the spacecraft.

[0060] Specifically, the voice fusion communication client can provide users with an intuitive operation experience through a graphical user interface (GUI). The client can be configured with encryption algorithms to implement password login and ensure the security of communication. Voice communication between clients can be achieved through the in-cabin network, while voice communication between space and ground relies on satellite relay communication links. Voice communication with extravehicular personnel may require specific radio equipment to overcome communication barriers inside and outside the cabin. In addition, the client can be configured with a voice recording function for recording communication content, as well as speech recognition and speech synthesis functions to support voice interaction.

[0061] Preferably, the client software can be designed to support multiple operating systems, such as Windows, Android, HarmonyOS, etc., to adapt to different computing environments. The speech recognition function of the client can integrate natural language processing technology to improve the accuracy and response speed of recognition. The speech synthesis function can adopt a high-quality speech engine to generate natural-sounding voice output.

[0062] Further, to improve the robustness of the system, the client can be designed with an automatic reconnection mechanism to automatically attempt to reconnect when the communication link is interrupted. In addition, the client can also provide user-defined settings, such as volume adjustment, communication mode selection, etc., to meet the needs of different users.

[0063] In some embodiments, the voice communication module of the voice fusion processing workstation integrates various audio interfaces such as network ports, U ports, serial ports, and telephone ports, and is respectively connected and communicates with the above-mentioned voice communication links such as short-wave communication, ultra-short-wave communication, microwave communication, Ethernet communication, and analog telephone communication, as well as the voice fusion communication client.

[0064] It should be noted that this embodiment focuses on the voice communication module of the voice fusion processing workstation. This module integrates various audio interfaces for connecting and communicating with different communication systems. The various audio interfaces mentioned here include network ports, U ports, serial ports, telephone ports, etc., which respectively correspond to different types of communication methods, such as Ethernet communication, USB communication, serial communication, and analog telephone communication.

[0065] Specifically, the voice communication module can be designed as a multi-functional interface board with various types of interfaces integrated thereon. For example, the network port may adopt an RJ45 interface for Ethernet communication; the U port may adopt a USB interface for connecting USB devices; the serial port may adopt a DB9 or DB25 interface for serial communication; and the telephone port may adopt an RJ11 interface for connecting an analog telephone line. These interfaces can be configured to support different communication protocols and data transfer rates to adapt to different communication requirements. The interface board can be designed modularly to add or replace interfaces as needed.

[0066] Preferably, the voice communication module can further integrate a signal conversion and amplification circuit to ensure effective signal conversion and transmission between different communication links. For example, the module can include a digital-to-analog converter (DAC) and an analog-to-digital converter (ADC) for processing the conversion between analog and digital signals.

[0067] Further, the module can also include a signal amplifier to enhance the signal strength and ensure the clarity of the signal in long-distance communication. To improve the compatibility and expandability of the system, a standardized interface design can be considered, such as following the IEEE standard or the recommended standards of the International Telecommunication Union (ITU). In addition, the module can be designed with an automatic detection and configuration function to automatically identify the type of connected device and automatically configure the communication parameters according to the characteristics of the device.

[0068] In some embodiments, the voice processing module of the voice fusion processing workstation uniformly processes the multiple voice signals transmitted through the above-mentioned voice communication module, including digital-to-analog conversion, encoding and decoding, resampling, noise suppression, and mixing processing, and then obtains a voice signal in a specific format, and transmits it to the voice fusion communication client through the voice communication module.

[0069] It should be noted that this embodiment describes the functions of the voice processing module of the voice fusion processing workstation, which is responsible for uniformly processing the multiple voice signals transmitted through the voice communication module. The unified processing here involves converting voice signals from different sources and formats into a specific format for subsequent processing and transmission. The specific format may refer to a standardized audio coding format, such as PCM (Pulse Code Modulation).

[0070] Specifically, the voice processing module can configure a series of processing steps, including digital-to-analog conversion, encoding and decoding, resampling, noise suppression, and mixing processing. Digital-to-analog conversion refers to converting analog signals into digital signals, and encoding and decoding involve compressing and decompressing voice signals for transmission. Resampling refers to adjusting the sampling rate of the voice signal to match the processing capabilities of the target system. The noise suppression function can reduce background noise and improve the clarity of the voice signal. Mixing processing refers to combining multiple voice signals into one output signal. These processing steps can set specific parameters, such as sampling rate, encoding bit rate, noise suppression threshold, etc., to optimize the quality of the voice signal.

[0071] Preferably, the voice processing module can use a high-performance digital signal processor (DSP) to implement these processing steps to ensure real-time and efficient processing. The module can be designed to support multiple audio coding formats, such as G.711, G.729, AAC, etc., to adapt to different communication requirements.

[0072] Furthermore, to improve the flexibility of the system, a configurable parameter setting interface can be considered to allow users to adjust the processing parameters according to the specific communication environment. In addition, the module can also integrate an adaptive algorithm to automatically adjust the processing parameters according to the quality of the communication link and the characteristics of the signal to optimize the transmission effect of the voice signal.

[0073] In some embodiments, the voice control module of the voice fusion processing workstation controls and schedules the multiple voice signals, obtains the control signaling in the multiple voice signals, and transmits it to the voice processing module, so that the voice processing module makes corresponding processing according to different voice signal sources.

[0074] It should be noted that this sentence describes the main functions of the voice control module of the voice fusion processing workstation, that is, to control and schedule multiple voice signals. The core task of this module is to obtain the control signaling in multiple voice signals and transmit it to the voice processing module for corresponding processing according to the different sources of voice signals. Here, the control signaling refers to the instructions or signals used to guide the voice signal processing flow, which may include information such as call establishment, call termination, volume control, etc.

[0075] As Figure 4 shown. The voice control module can be designed as a highly integrated system that can identify and parse the control signaling from different voice communication links. These control signaling may exist in different formats, such as DTMF (Dual Tone Multi-Frequency) signals or SIP (Session Initiation Protocol)-based signaling. The module needs to be able to parse these signaling and control the routing and processing of voice signals according to the content of the signaling. For example, if a call establishment signaling is received, the module will instruct the voice processing module to prepare the corresponding communication link and start the necessary processing procedures.

[0076] Preferably, the voice control module can adopt advanced signaling analysis technologies, such as machine learning algorithms, to improve the recognition accuracy and processing speed of control signaling. In addition, the module can be designed to support multiple communication protocols and signaling formats to ensure compatibility with different communication systems. To improve the reliability of the system, redundant design can be implemented, such as setting up multiple control modules to achieve failover.

[0077] More specifically, the module can also integrate a user interface that allows operators to manually input control signaling for easy intervention when problems occur in the automatic system. In addition, the module can be designed to record all signaling activities for easy post-event analysis and troubleshooting.

[0078] In some embodiments, the voice fusion communication client software can be deployed on computers with operating systems such as Windows, Android, HarmonyOS, etc. This client software has modules for voice fusion communication function, log management function, voice file management function, voice interaction function, and client settings function.

[0079] It should be noted that this sentence describes the deployment environment and functional modules of the voice fusion communication client software. This client software can be deployed on computers with operating systems such as Windows, Android, HarmonyOS, etc., which means that the software needs to be compatible with these different operating systems. Here, the operating system refers to the basic software running on the computer that manages the computer's hardware resources and provides an interface for users to interact with the computer.

[0080] Specifically, the functional modules of the client software include a voice fusion communication function, a log management function, a voice file management function, a voice interaction function, and a client settings function module. These functional modules together constitute the core of the client software, enabling it to perform voice communication, record and store voice logs, manage voice files, conduct voice recognition and interaction, and allow users to configure the client according to their needs. For example, the voice fusion communication function module can support multiple communication protocols to achieve communication between different clients; the log management function module can record communication history for easy query and analysis by users.

[0081] Preferably, the client software can be designed to be highly user-friendly, providing an intuitive graphical user interface (GUI) that enables users to easily conduct voice communication and configure the client. The software can provide multi-language support to meet the needs of different users.

[0082] More specifically, the voice interaction function module can integrate advanced natural language processing technologies to improve the accuracy and response speed of voice recognition. The client settings function module can allow users to customize communication parameters such as volume, echo cancellation, etc. to optimize the communication experience.

[0083] Furthermore, the software can be designed to support automatic updates so that users can receive the latest function improvements and security patches in a timely manner. To enhance the security of the system, the client software can also integrate encryption technologies to ensure the confidentiality and integrity of communication data.

[0084] In some embodiments, the communication process between the voice fusion processing workstation and the voice fusion communication client includes:

[0085] The ground simultaneously calls multiple voice fusion communication clients inside the spacecraft cabin through the microwave communication link of the relay satellite;

[0086] The voice communication module in the voice fusion processing workstation sends the call signal to the voice control module. The voice control module, by obtaining the control signaling in the call signal, sends the call signal to the ground links of each client respectively, causing the ground links of the called clients to ring and connect simultaneously;

[0087] The ground transmits the voice signal to the voice fusion processing workstation through the microwave communication link of the relay satellite. The internal voice communication module sends the voice signal to the voice control module and the voice processing module. The voice control module obtains the control signaling in the voice signal and sends it to the voice processing module. The voice processing module processes the voice signal accordingly and then sends the voice signal to the ground links of each client respectively;

[0088] After receiving the voice signal, each voice fusion communication client makes a response and sends the response voice signal to the voice control module and the voice processing module through the voice communication module. The voice control module obtains the control signaling in the client voice signal and sends it to the voice processing module. After the voice processing module processes the voice signal accordingly, it sends the voice signal back to the ground through the microwave communication link, thus establishing voice communication between space and ground.

[0089] It should be noted that this sentence describes the communication process between the voice fusion processing workstation and the voice fusion communication clients. This process involves the interaction between the ground and multiple voice fusion communication clients inside the spacecraft cabin through the microwave communication link of the relay satellite. Here, the relay satellite refers to the satellite operating in the Earth's orbit, which is used to forward signals to achieve communication between the ground and the spacecraft.

[0090] Specifically, the communication process starts with the ground simultaneously calling multiple voice fusion communication clients inside the spacecraft cabin through the microwave communication link of the relay satellite. This process involves the uplink of the signal, that is, the signal transmission from the ground to the spacecraft. After the voice communication module in the voice fusion processing workstation receives the call signal, it sends it to the voice control module. The voice control module, according to the control signaling in the call signal, sends the call signal to the ground links of each client respectively, so that the ground links of the called clients ring and connect simultaneously. This process involves the downlink of the signal, that is, the signal transmission from the spacecraft to the ground.

[0091] Preferably, in order to ensure the reliability and efficiency of communication, an intelligent routing system can be designed, which can automatically select the best relay satellite and communication path according to the quality of the communication link and the signal strength.

[0092] More specifically, the voice control module can integrate an algorithm for dynamically adjusting the processing and routing of voice signals to adapt to changes in the communication environment. In addition, in order to improve the security of communication, encryption technology can be adopted during the transmission of voice signals.

[0093] Furthermore, after the voice signal reaches the ground, the ground system can be designed with an automatic recording and storage function for subsequent communication records and analysis. In addition, an user interface can also be considered to be integrated into the client software, allowing users to view the communication status and history records, as well as set communication parameters.

[0094] In some embodiments, the voice fusion processing workstation is provided with a voice recording module to implement functions such as real-time voice recording and historical voice traceability of multi-system fusion voice communication.

[0095] It should be noted that this sentence describes the function of the voice recording module in the voice fusion processing workstation. This module is used to achieve real-time voice recording of multi-system fusion voice communication and historical voice tracing. Here, real-time voice recording refers to the instant capture and storage of voice data during communication, while historical voice tracing refers to the ability to review and retrieve past communication records.

[0097] Preferably, the voice recording module can further integrate intelligent analysis tools, such as speech recognition technology, for automatically transcribing voice content and generating text records. More specifically, this module can be designed to support multiple voice formats and coding standards to ensure compatibility with different communication devices.

[0098] Furthermore, to improve the reliability of the system, a redundant storage strategy can be implemented, such as storing the same voice data in multiple locations to prevent data loss. In addition, the module can also be designed to support remote access and control, allowing authorized users to retrieve and analyze voice records from different locations. To ensure data security, encryption technology can be used to protect the stored voice data.

[0099] In some embodiments, a voice interaction module is provided in the voice fusion processing workstation to achieve voice recognition of multiple voice calls and the function of voice synthesis for device alarm information.

[0100] It should be noted that this sentence elaborates on the function of the voice interaction module in the voice fusion processing workstation. This module is used to achieve voice recognition of multiple voice calls and the function of voice synthesis for device alarm information. Here, voice recognition refers to the technology of converting human voice into text or commands, while voice synthesis refers to the technology of converting text into understandable voice.
