Off line speech recognition chip vb580 intelligent speech scheme customized home appliance control board integrated circuit board details

Product features:

1. The main frequency of vb580 chip is 200m, and ADC / DAC, SRAM and flash are integrated inside. The peripheral circuit is simple, as long as the crystal oscillator and power amplifier chip. Qsop24 package.

2. The chip integrates GPIO, UART, I2C, SPI and other interfaces and peripheral communication.

3. Off line speech recognition (based on the new TDNN deep neural network recognition algorithm, without networking), the comprehensive recognition rate can reach more than 95%.

4. Support recognition distance of more than 5m.

5. The recognition time is less than 100 milliseconds and the response is very fast.

6. The misjudgment rate is very low.

7. Background noise suppression: steady state and dynamic noise, ambient noise suppression > 20dB. Normal identification under range hood noise.
