Description:

The PCB of the VB-01-Kit development board has added the interface of the VB-02 module, so that the VB-02 module can also beconnected to the PCB.
 
    The main chip is the voice brain VB590 launched by Huazhen Company. It has the characteristics of 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-01 uses a high-performance 32-bit processor, the chip has built-in DSP instruction enhancement unit and MCA algorithm hardware accelerator required for speech recognition neural network calculations, AI algorithm and chip architecture are deeply integrated, equipped with speech recognition algorithms, speech enhancement, and noise reduction And other acoustic front-end processing algorithms provide 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-01 has a wealth of peripheral interfaces, including UART/I2C/PWM, and simple and friendly secondary development tools to facilitate customers to implement single-module voice control application scenarios.

Features:

Key technical indicators;
Ø Adjustable recognition distance: support 5 meters recognition distance
Ø Background noise suppression: steady-state, dynamic noise, environmental noise suppression>20dB
Ø Local speech recognition (based on the latest TDNN deep neural network recognition algorithm), supporting pure offline recognition
Ø The comprehensive recognition rate can reach more than 98%
Ø Recognition time is less than 100 ms
Ø Very low misjudgment rate
Ø Up to 50 entrie
