TTS Speech Synthesis Speaker Module with Microcontroller Serial Control Playback

TTS Chinese Speech Synthesis Module for Microcontroller Projects This compact TTS module converts serial data into clear spoken Chinese, making it a straightforward addition to microcontroller-based projects. It is designed to work with common 5V and 3.3V serial ports, so you can integrate voice output without complex circuitry or additional hardware. Simple Serial Control The module operates at a fixed communication baud rate of 9600, 8, n, 1, which keeps setup uncomplicated. Whatever your serial port transmits, the module speaks aloud. For example, sending the command printf("Hello everyone") through your microcontroller results in the speaker broadcasting "Hello everyone". The module supports numbers, letters, and Chinese broadcasts, giving you flexible options for announcements, alerts, or interactive responses. Direct Connection and Wiring You can connect the module directly to a USB to TTL module for testing, which is convenient during development. The wiring follows a clear colour sequence: red connects to 5V, green to RX, yellow to TX, and black to GND. This straightforward layout helps you get the module running quickly, whether you are prototyping on a bench or embedding it into a finished build. Practical and Economical Voice Output Because the module relies on direct serial control, it removes the need for additional audio processing hardware or pre-recorded sound files. This makes it a practical choice for robot announcements, status reporting, or any project where spoken feedback adds value. The combination of simple wiring, fixed baud rate, and direct serial command makes it an economical way to add Chinese speech synthesis to your designs.
