Voice Recognition Chip

Long-distance wake up

Stronger noise immunity
Recognize faster

· Affordable · Reliable · Generic

Core and Storage

  • High performance 32 bits core, 240Mhz, support floating point arithmetic.
  • Internal 1MB SPI-Flash

AI Algorithm

  1. Offline voice recognition: Offline speech recognition, using neural network algorithm, has the advantages of accurate recognition, low misjudgment rate, etc., and reliable recognition at 5 meters.
  2. Voice noise reduction algorithm: filter steady-state noise, and also have a good inhibitory effect on dynamic noise. Accurate recognition under noise
  3. Voice decoding: support MP3, WAV format
