1¡¢ACCURATE EFFECT: The chip of the TTS voice module supports Chinese and English text synthesis, providing clear, natural, and accurate speech synthesis 2¡¢ENCODING MODE: The voice module supports GB2312, GBK, and Unicode encoding modes. Up to 4K bytes of text can be synthesized at a time 3¡¢TWO COMMUNICATION MODES: The voice module chip supports the UART and SPI communication modes. When the UART serial port resources are occupied, you can choose to use the SPI interface 4¡¢BAUD RATE: The chip of the speech synthesis module supports standby mode. You can use control commands to set the chip to standby mode. The baud rate supported by the chip includes 4800bps, 9600bps, 57600bps, and 115200bps 5¡¢SMALL SIZE AND POWER CONSUMPTION: The TTS speech synthesis module features small size, patch package, simple hardware interface, low power consumption, and a clear, round sound that is close to a human voice 6¡¢POWERFUL FUNCTION: SYN6988 adds English text parsing and English voice library, which is a real Chinese English speech synthesis chip for high end industry applications. The hardware and communication interface are fully compatible with the chip, receiving text data to be synthesized and realizing text to speech(or TTS speech) conversion 7¡¢APPEARANCE FEATURES: The module has an on board four digit dip switch for baud rate selection, a power indicator, the size of the positioning hole and the position of the pins are consistent with the 5152 module
