During the Chengdu auto show in August, Geely’s new SUV boyue x made its debut. In appearance, the front face of storm armor has a distinctive and powerful sense, with high recognition; At the same time, in the smart car system, boyue x not only connected to Baidu map auto version, but also took the lead in carrying the Honghu chip independently developed by Baidu. This is also the first application of Baidu Honghu chip in mass production models.

The new vehicle machine system carried by Geely boyue x is jointly built by Geely Automobile, baidu Apollo and Yikatong technology. It has made major innovations in voice interaction technology innovation and humanized design, and opened a new chapter in the development of vehicle voice interaction to a higher stage. Baidu Honghu chip used in boyue x car machine system is a “gauge core” in the industry that integrates complete signal processing, language wake-up and command word recognition.
Baidu Honghu voice chip has launched a new design idea of “AI algorithm definition chip”, which adopts the dual core hifi4 architecture to customize the instruction set, has large memory, has the array signal processing algorithm ability to support the far-field voice interaction core, and also supports the in-depth learning and computing ability that can be used for wake-up. Baidu Honghu chip is developed according to the concept of software defined chip, and integrates the front-end signal processing, wake-up word technology and instruction word technology into Honghu chip, which greatly reduces the computing power overhead of the main control chip, thus further reducing the problems such as jamming and overheating of the main control chip. In the case of vehicle voice interaction, users can wake up and input commands more frequently and flexibly, and can experience very smooth vehicle machine functions.

Baidu Honghu chip also has the integrated modeling technology of speech enhancement and acoustic modeling of complex CNN, which breaks the interdisciplinary barrier of digital signal processing and speech recognition, so that the first wake-up rate under high noise can be increased by more than 10%, and the speech recognition rate can be greatly improved, with few recognition errors, Effectively alleviate the user anxiety, abandonment and other problems caused by the difficulty of waking up the system function. The speech recognition system can also realize the functions of “visible to speak” and “multi sound area anti-interference”. When the user reads the words on the screen directly, the system can realize analog click and reduce the user’s hands-on operation. At the same time, the system can also accurately distinguish the position of the person who sends the voice command, prevent noise interference, and perform the function corresponding to the position.
The voice interaction system supported by Baidu Honghu chip is also equipped with a voice semantic edge computing solution. The solution is jointly developed by yiketong technology and Baidu Apollo. It can give priority to semantic local parsing, and the local parsing effect can be comparable to that of cloud parsing. Combined with the preloading strategy, it can locally respond to the voice interaction of most car owners, make the voice interaction faster and better privacy security, and avoid the response delay caused by network instability to the greatest extent. At the same time, the voice interaction system also supports the panoramic pronunciation of real people, and can provide a variety of interesting and personalized voice packages. Users can also customize real person pronunciation by recording. Personalized voice package and customized real person pronunciation can be used for global pronunciation of vehicle machine system including navigation.

At the same time, the “Baidu map auto version” developed and customized by Baidu Apollo has also been fully implemented in Geely Automobile. As the latest model carrying Baidu map auto version, boyue x integrates Baidu’s core search recommendation ability, and can provide the owner with a unique real-time picture viewing service after POI arrival in combination with the user’s preference for intelligent recommendation search results. At the same time, the inertial navigation ability of Baidu map auto version is further improved. On the streets without GPS signal or poor GPS signal such as tunnels, viaducts and skyscrapers, it can calculate and update the vehicle position in real time, which perfectly solves the problem caused by the lack of GPS signal during driving. In addition, users can also customize the exclusive navigation broadcast voice package to completely refresh the vehicle voice interaction experience.
With the help of the vehicle specification level vehicle machine voice interaction system represented by Baidu Honghu chip and Baidu map auto version, boyue x will bring more smooth and efficient vehicle machine interaction experience to consumers.
