【產品簡介】

The main chip of VB-02 is the voice brain VB590 launched by Huazhen Company. It is a chip that adopts offline voice recognition AI, software and hardware integrated solutions, with ultra-low cost, high reliability, and strong versatility. In the speech recognition technology, it has achieved high-reliable wake-up recognition rate, longer-distance wake-up, lower false wake-up rate, stronger anti-noise ability, faster response recognition time, and pure offline recognition without networking.

VB-02 uses a high-performance 32-bit processor, the chip has built-in DSP instruction enhancement units and MCA algorithm hardware accelerators required for speech recognition neural network calculations, and the AI algorithm is deeply integrated with the chip architecture. It is equipped with the company’s fifth-generation AI algorithm (voice recognition algorithms, voice enhancement,

noise reduction and other acoustic front-end processing algorithms), providing smart devices with excellent voice control and voice interaction capabilities in the far-field environment. The main chip has been fully and deeply optimized in AI computing power, storage performance, and integration, providing developers with a truly low-cost complete voice AI solution and enhancing differentiated competitiveness.

VB-02 has a wealth of peripheral interfaces, including UART/I2C/PWM, and simple and friendly secondary development tools, which are convenient for customers to implement single-module voice control application scenarios.
