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
- 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.
- Voice noise reduction algorithm: filter steady-state noise, and also have a good inhibitory effect on dynamic noise. Accurate recognition under noise
- Voice decoding: support MP3, WAV format
