Give your Arduino project a voice with this text-to-speech shield. Built around the IFLYTEK XFS5051CE speech synthesis chip, it converts text strings into spoken audio in English and Chinese, with support for both male and female voices and 11 adjustable speaking speeds.
The shield stacks directly onto standard Arduino boards and communicates over UART, I²C, or SPI. It includes a Run/Prog switch and a busy LED indicator. Just connect a speaker and start sending text — the shield handles all the synthesis work.

Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
