7801-3


  • High-performance 32-bit RISC core at 240MHz with hardware floating point support

  • Built-in 512KB SPI FLASH

AI algorithm

  • Offline speech recognition, using the latest neural network (TDNN) algorithm, has the

advantages of accurate recognition, low false positive rate, 5 meters far-field reliable

recognition, as follows:

  • VB7801 chip supports English recognition

  • VB7801 chip support Asia, Europe, South America and other small language

recognition, constantly adding updates, support language details please consult

our sales staff.
