Clear, natural and accurate Chinese-English sound synthesis effect. The chip supports the synthesis of Chinese and English texts, and can use three encoding methods: GB2312, GBK and Unicode. The amount of text synthesized each time can reach 4K bytes. Two communication modes: the chip supports UART and SPI two communication modes. When the user UART serial port resources are occupied, the SPI interface can be . The chip supports standby mode. Use the control to make the chip enter the standby mode. Communication baud rates supported by the chip: 4800bps, 9600bps, 57600bps, 115200bps. Small size, SMD package, simple hardware interface, low power consumption, clear and sound, close to human voice, high cost performance.
