A microphone array module designed for AI, robotics, and voice interface applications. It utilizes an XMOS XVF3800 processor and four MEMS microphones to deliver real-time audio processing with features such as noise reduction, echo cancellation, beamforming, and sound source direction detection. Its voice detection range is up to 5 meters, and its 180° pickup pattern enables precise spatial speech capture. Integration with the XIAO ESP32S3 and support for USB and I2S make the module easy to implement in embedded projects and voice control systems. Seeed Studio 100099135
Description
reSpeaker Flex XVF3800 Linear-4 is an advanced microphone array module designed for applications in robotics, embedded systems, and interactive HMI devices. The device is based on the XMOS XVF3800 processor, which delivers high-quality real-time audio signal processing. Thanks to built-in AI algorithms such as noise suppression (NS), echo cancellation (AEC), and beamforming, the module significantly enhances captured audio quality. The split-design construction, separating the processing unit from the microphone array, allows flexible placement of components in robotic projects and space-constrained devices.
The version supports integration with XIAO ESP32S3 (not included), enabling direct compatibility with MCU ecosystems such as Arduino and ESPHome, which simplifies rapid deployment of voice-based projects. Support for USB and I2S modes ensures wide compatibility with computers, Raspberry Pi, NVIDIA Jetson, and microcontrollers. The 4-microphone array enables precise sound capture within a 180° range, making it ideal for front-facing applications such as information kiosks or control panels.
The system offers a voice capture range of up to 5 meters, allowing convenient voice control in larger spaces without the need to be close to the device. Thanks to DoA (Direction of Arrival) technology, it is possible to determine the direction of the sound source, improving interaction precision in robotics and AI systems. The module is designed for professional applications, offering high resistance to interference and stable operation even in challenging acoustic environments. Built-in interfaces and DFU support enable easy firmware updates and device customization. The reSpeaker Flex XVF3800 Linear-4 is a comprehensive solution for projects requiring advanced voice recognition and processing.
