XF-S4240 speech synthesis module data manual introduces the module's overview, features, main application areas, system block diagram, function description, communication mode, module control, and circuit references.
The XF‑S4240 is a high‑end Chinese text‑to‑speech (TTS) module that can synthesize arbitrary Chinese text and English letters. It supports multiple character encodings (GB2312, GBK, BIG5, Unicode) and offers male and female voice outputs with natural sounding speech.
The module provides three communication interfaces—UART, SPI and I2C—allowing integration with host controllers. Detailed pin assignments, electrical limits, and functional characteristics are listed for designers. This manual is written in Chinese.
