The XF-S4240 Chinese speech synthesis module is the latest research result of InterSound4.0 Chinese speech synthesis system based on the latest research results of Keda Xunfei in the field of embedded Chinese speech synthesis launched by Anhui Zhongke Daxun Information Technology Co., Ltd. (Keda Xunfei). A Chinese speech synthesis module designed. The module can receive the text to be synthesized through asynchronous serial port (UART), SPI interface and I2C bus, and directly synthesize it into voice output; it is mainly for medium and high-end applications, providing a complete and inexpensive voice solution. Program.
1.2 FeaturesCan synthesize any Chinese text and support the synthesis of English letters;
Supports text in four internal code formats of GB2312, GBK, BIG5, and UNICODE;
With intelligent text analysis processing algorithm, it can correctly identify and process numerical values, numbers, time and date and some commonly used weights and measures symbols, and has strong multi-tone processing and Chinese surname processing ability;
Double speakers: male voice, female voice;
Clear, natural and accurate speech synthesis effects;
Integrated prompt sound for common voice prompts in certain industry sectors;
Support software to adjust speech rate, intonation, volume;
Support a variety of control commands, including: synthesis, stop, pause synthesis, continue to synthesize, etc.
Support multiple text control tags to improve the correct rate of text processing;
Support sleep function, can reduce power consumption in sleep state;
Support UART, SPI, I2C three data communication interfaces;
Line out audio output;

1.3 FeaturesThe XF-S4240 Chinese Speech Synthesis Module is a speech synthesis module designed for embedded applications, with the ability to synthesize arbitrary Chinese text and English alphabet synthesis. The main feature of this module is that the synthesized speech has high naturalness, and the control interface is simple and convenient, and powerful.
2 Hardware interface of XF-S4240 module2.1 XF-S4240 Pin Description
Since the development board only has a serial port for external connection, we use the UART communication method.
The serial port settings are as follows:
1) Baud rate: 9600 bps
2) Start bit: 1bit
3) Data bits: 8 bits
4) Stop bit: 1 bit
5) Check: None
