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.
Speech Noise Reduction Algorithm: Filter out steady state noise, also has good
suppression effect on dynamic noise, and can be accurately recognized under noise.
