Overview
Yahboom Speech Synthesis Broadcast Module is an I2C (IIC) speech synthesis board built around the XFS5152CE chip for Chinese and English text-to-speech, including mixed Chinese-English reading. It supports text intelligent analysis/text processing and provides onboard speaker output for voice broadcast in robotics and programming projects. Connection options include alligator clip, DuPont line, and PH2.0 cable methods for quick integration with common controllers.
Key Features
- Integrated speech synthesis chip: XFS5152CE; supports Chinese and English speech synthesis and mixed reading.
- Supports four encoding methods: GB2312, GBK, BIG5, UNICODE.
- Maximum text synthesized each time: up to 4K bytes.
- Recognizes and processes common formatted text such as numbers, time, date, weights and measures symbols, based on built-in text matching rules.
- Processes polyphonic Chinese characters and Chinese surnames.
- Multiple built-in voices available for selection.
- Adjustable voice broadcast parameters: 10 levels of speech rate, 10 levels of tone (intonation/pitch), and 10 levels of volume.
- Integrated 80 common prompt sound effects (e.g., information prompts, ringtones, alarms).
- Supports multiple control commands such as synthesizing text, stop synthesizing, and status query.
- Three connection methods: DuPont line interface, alligator clip interface, PH2.0 foolproof interface.

Details

Skip voice interaction features you don’t need—this board focuses on reliable I2C text-to-speech broadcasting.

If you’re choosing between voice boards, focus on interface type and whether you need recognition versus speech output.

Built around XFS5152CE for Chinese/English text-to-speech, with a straightforward IIC (I2C) control interface.

Clear pin labels make wiring quick: power plus SDA/SCL for I2C control.

Compact 45.3 × 28.1 mm board size fits neatly into small robotics and classroom builds.

Supports common encodings (GB2312/GBK/BIG5/Unicode) and up to 4K bytes per synthesis command.

Useful for projects that need spoken prompts in English, Chinese, or mixed-language output.

Add spoken feedback to interactive robots—status prompts and behaviors can be voiced in real time.

Combine sensor data with voice output for audible readings like temperature, humidity, time, and numbers.

Works across popular platforms including Raspberry Pi, Arduino, micro:bit, and more via I2C.

Fine-tune voice speed, pitch, and volume through commands, plus built-in prompt sound effects.

Choose the wiring style that suits your build: DuPont headers, alligator clips, or a keyed PH2.0 connector.

Alligator clips offer a fast, beginner-friendly way to prototype with micro:bit-style boards.

DuPont jumpers and PH2.0 cables provide cleaner, more secure connections for longer-running projects.

Skip extra shopping by adding jumper wires if your controller doesn’t include them.

A PH2.0 cable is ideal when using expansion boards that support keyed 4-pin connections.

Scale from simple demos to full systems—the module integrates well with common controller ecosystems.

Add voice prompts, alerts, and narration to a wide range of DIY robot kits and learning platforms.

A compact voice-broadcast obstacle-avoidance robot car combines a sensor module and drive wheels for interactive learning builds.

The I2C speech module is used here to announce sensor readings like 30°C temperature and 60% humidity through a connected speaker.

Official Yahboom study resources include micro:bit, Arduino, and Raspberry Pi course files plus PDF and Word documents for XFS5152CE speech synthesis.

A downloadable 3D model file is available to help plan mounting and enclosure design for DIY builds.

The XFS5152CE I2C voice broadcast module uses clearly labeled SDA/SCL and power pads to simplify wiring into Raspberry Pi or Arduino projects.

The Yahboom I2C voice broadcast module includes an onboard speaker and clearly labeled VCC, GND, SDA, and SCL pins for simple wiring to Raspberry Pi, Arduino, or micro:bit projects.

Yahboom universal series modules provide a mix of sensor and input boards for quick prototyping with common controller platforms.

The XFS5152CE I2C speech synthesis broadcast module includes an onboard speaker plus PH2.0, DuPont, and alligator-clip connections for simple wiring.
