update the voice content description
The JQ8400 voice chip uses the SOC solution, integrates a 16-bit MCU, and an ADSP dedicated to audio decoding. It uses hard decoding to ensure the stability and sound quality of the system. The compact size is more suitable for embedding other products.
SPI-flash to change voice content
The biggest advantage of this chip is that it can flexibly replace the voice content in the SPI-flash, eliminating the trouble
that the traditional voice chip needs to install the host computer to change the voice. The SPIFLASH is directly simulated into a USB disk, which is very convenient as a copy of the USB disk. Make product development and production easy and simple. The first-line serial port control mode and RX232 serial port control are optional, providing more selectivity for R&D.
