Cost-effective intelligent dual-mic voice interaction solution

Overview
R6 integrates ARM9 architecture that operates at speed up to 600MHz. A 32MB DDR is embedded in R6. It realises complete voice function under limited cost, and supports mixed interaction between off-line local command word recognition and on-line cloud ASR recognition. R6 includes rich interfaces such as ADC, DAC, I2S/PCM, USB OTG, SD/MMC, UART, SPI, and TWI. Besides, R6 supports TINA OS. R6 is qualified to industrial standard in white electricity industry.
Highlights
Dual-mic middle-near field intelligent voice interaction
R6 integrates ADC, DAC, and I2S/TDM interface, which meets the basic computing rate requirements of dual-mic noise reduction, AEC, wake-up, local command word algorithm, cloud ASR, and IoT interaction. R6 is an ideal choice of middle-near field voice interaction solution.
