Sound is invisible, but it defines the interactive experience of smart cars. A voice wake-up response that can be heard everywhere in the car condenses countless days and nights of technical polishing by R&D engineers. The second phase of the "China Intelligent Manufacturing Exploration Plan", jointly produced by the Ministry of Industry and Information Technology's Press and Publicity Center and Automobile House, entered the domestic AI intelligent voice head enterprise Xunfei, digging into the R&D story of in-vehicle voice technology and demonstrating China's "artificial intelligence + intelligent manufacturing" hardcore strength. The theme feature film "From One Sound to All Things" was officially launched online on September 23. The visiting delegation of the "China Intelligent Manufacturing Exploration Plan" walked into the in-vehicle voice track of the University of Science and Technology. The University of Science and Technology is an industry participant behind the scenes, and the domestic market scale of related products continues to be at the forefront of the industry. For every 4 cars sold in China, 1 car is equipped with the relevant products of the University of Science and Technology Xunfei. Up to now, the cumulative loading capacity of on-board voice interaction has exceeded 77.5 million sets, deeply empowering the domestic intelligent cockpit industry to upgrade. The AI smart cabin innovation practice from China Sound Valley As a voice service provider, what is the background of "smart manufacturing"? In mid-September, the delegation of the "China Intelligent Manufacturing Exploration Plan" immersed in the "China Sound Valley" to visit the artificial intelligence industry base of the University of Science and Technology. The visit process is divided into two parts: a visiting experience and a closed-door discussion. Members of the visiting delegation successively visited the University of Science and Technology's Xunfei Artificial Intelligence Experience Hall and the national Wanka computing power cluster "Feixing One" jointly created by the company and Huawei, and also experienced "Spark Compartment 3.0" and "iFLYSOUND Smart Sound Field" in batches. After the visit, the members of the visiting delegation held in-depth closed-door conversations with the top executives of Xunfei University of Science and Technology. The "China Intelligent Manufacturing Exploration Plan" delegation explained that the "Feixing No. 1" AI Experience Pavilion is a high-standard external exhibition hall built by the company, which shows more comprehensively how the university promotes artificial intelligence technology based on the "Spark Model", empowering many industries such as life, education, medical care, and automobiles. "Feixing One" is the computing power bottleneck of Xunfei University and Huawei to break through the large model training. It uses 100 days to build a million-card high-speed interconnection ultra-large-scale intelligent computing platform from scratch to carry the full stack of computing, storage and network self-developed architecture. In October 2024, Xunfei Spark 4.0 Turbo based on the cluster training was released, and the "Feixing 2" project was launched. The "Spark Cockpit 3.0" to be released by the University of Science and Technology Xunfei within the year, the underlying computing power operation is completely supported by this domestic intelligent computing platform. At the closed-door meeting of the "China Intelligent Manufacturing Exploration Plan" visiting group, the University of Science and Technology Xunfei "Spark Cockpit 3.0", in addition to discussing the thinking during the visit, the University of Science and Technology Xunfei also demonstrated the next-generation cockpit solution and global layout plan based on the large model; the Automobile House analyzed the status quo of the development of automobile intelligence based on the data factory and user research. In view of the synergy between technology and industry, all parties reached a consensus on avoiding homogeneous competition and enhancing user perceived value: in the future, the University of Science and Technology will support the customization of automobile enterprises through diversified solutions, and will establish differentiated advantages through cross-disciplinary technical value transformation; all parties will also work together to enhance user perceived value through ecological collaboration, standard co-build, and scenario-based communication. Behind the technical details that determine the smart manufacturing of quality hard cores is the spirit of exploration of the R&D team. At the University of Science and Technology, several R&D engineers also use their spare time to rehearse their performances by forming internal bands, perceiving the sound logic of musical instruments, and reversing the acoustic tuning work on the car. Although 80% of the tuning work is done by intelligent technologies such as AI, they still believe that human tuners are indispensable. Because people have emotions that AI can never understand, the tuner will eventually complete some details, especially the adjustment of the emotional experience level. It was also because of their honed super ear that they were able to hear the current in-vehicle woofer with insufficient power that they were able to develop the GaN master-grade acoustic system that had just been released in April this year. It can achieve a single-channel peak of 300W (Pro version 16-24 channels, peak 2880W), improve sound quality by 20%, reduce weight by 30%, and effectively reduce costs. As cars become smarter, the boundaries that voice interaction technology can explore become larger and larger. As the head of the voice market, Xunfei is also constantly exploring the boundaries where "AI intelligent voice" can play a role in smart cars. Today, their "Spark Cockpit 3.0" has become a cockpit intelligent interaction hub that realizes everything from "hearing clearly" to "understanding" to "remembering" to "doing things". In order to make the "Spark Cockpit 3.0" better land on automotive products, the complete development cycle of the single cockpit solution is up to half a year to one year. According to the staff of the University of Science and Technology, from the start of the project to the official delivery, the University of Science and Technology Information Flight will conduct acceptance twice a week. The questions raised for each acceptance will be the direction of the next optimization. In other words, each project requires more than 40 iterations to be delivered. This kind of repeated verification, the spirit of strict control over all details, may be the spirit of Chinese intellectual creation upheld by the University of Science and Technology, Xunfei. "China's smart manufacturing, first of all, to improve the quality of products as the goal. In the process, technology is constantly transformed into value that users can experience and perceive." In the view of Wu Xiaoru, president of the University of Science and Technology Xunfei, this is a very important part of his "Chinese wisdom". Building a bridge between the public and hardcore science and technology innovation The Chinese automotive industry is in the midst of an unprecedented and profound transformation. The waves of electrification and intelligence are on the rise, and the market competition is unprecedented. In the noisy public opinion environment, the value of technology input is easy to be ignored, and it is difficult for enterprises to be accurately perceived in marketing noise. This means that both the industry and the public need to find a way to penetrate the noise and see the true background and long-term value behind the brand and technology. The "China Intelligent Manufacturing Exploration Plan" hopes to let everyone see the backbone of those who really decide "intelligent manufacturing strength" through enterprise visits. For Chinese intelligent manufacturing forces such as Xunfei, which has been "hidden behind" for a long time, the "China Intelligent Manufacturing Exploration Plan" is not only a high-quality sound platform, but also a connector between manufacturing enterprises and ordinary automobile consumers, helping them to establish a clear brand mental awareness in the hearts of more consumers. After more than 20 years of in-depth development, the "China Intelligent Manufacturing Exploration Plan" delegation has built an industrial service system with a total number of users exceeding 500 million, connecting nearly 30,000 cooperative 4S stores, 12,000 used car dealers and more than 100,000 family car service resources, covering 369 cities across the country. These 500 million users precipitate the domestic leading scale and rich dimensional full behavior database of vehicle owners. This deep trust from users is the core driving force for Automobile House to continue to build the "China Intelligent Manufacturing Exploration Plan" and insist on promoting more high-quality Chinese intelligent manufacturing forces to the public. Among all the visit contents exported to the outside world, Auto House refuses to pile up obscure and cold technical terms, but hopes to take "sincere companionship" as the core gesture, act as a professional "translator" between ordinary consumers and cutting-edge smart technology, dismantle complex technical concepts, so that users can more intuitively and clearly perceive the hard core strength and long-term value of Chinese smart technology. Next, the visit of the "China Intelligent Manufacturing Exploration Plan" will not stop. We will continue to visit excellent track companies such as vehicle manufacturing, intelligent cockpit, and body intelligence to explore more stories of China's intelligent manufacturing and innovation, so that more hard-working science and technology enterprises can be seen by the public, and help China's intelligent manufacturing capabilities penetrate into the hearts of the people.
