Intelligent Voice Control Kit

This kit integrates a USB sound card with a 4/6-mic array, featuring CAE noise suppression and AEC echo cancellation. With a built-in amplifier for direct speaker drive, it includes an AI SDK and AIUI cloud services for low-code, rapid integration. It offers a mic sensitivity of -32 dB and 65 dB SNR, enabling reliable wake-up within 3-5 meters. The wide-temperature, low-power design ensures versatility across various applications.

Dual-Mic Array Design

Configurable with linear 4-Mic and circular 6-mic arrays. These enable 180°/360° sound source localization, Integrated with CAE noise suppression, it delivers effective pickup within 3-5 meters and achieves ±15° localization accuracy for comprehensive and precise sound capture.

Direct Drive for Dual Speakers

Equipped with a built-in amplifier capable of directly driving dual 8Ω/5W speakers. It supports AEC echo cancellation and voice interruption, ensuring clear and powerful audio output for seamless, low-latency voice interaction.

Al SDK & Low-Code Integration

Empowered by an AI SDK and supported by AIUI cloud services, the platform enables rapid low-code integration. With comprehensive resources including demo source code and professional technical support, it accelerates deployment and significantly shortens project cycles.

Anti-Interterence

The system delivers robust anti-interference capabilities, maintaining high accuracy in both low and high-noise environments. It achieves a 93% wake-up rate and 94% word accuracy in quiet conditions, while retaining 87% and 86% respectively in noisy settings, ensuring stable and reliable performance in complex scenarios.

Compatible Multiple Hardware

Compatible with embedded boards running Android, equipped with USB and Line-out interfaces, such as Firefly's AIO-3588SJD4, ITX-3588J, and ITX-3568JQ.

Low Power & Wide Temp

Low-Power Design: 14-16mA in silent mode. Operating temp: -10℃ to 70℃. Storage temp: -40℃ to 85℃. Reliable in diverse environments.

Ultra-Thin Design

Both USB sound card and microphone array board maintain an 8mm maximum height, the boards feature a compact size for flexible installation, adapting to various space-constrained device scenarios.

Easy Debug Interfaces

Equipped with Type-C, 3.5mm audio input, AEC feedback interface, speaker interface, reset button, and programming button, this solution enables efficient hardware expansion and effortless post-deployment debugging.
