As generative AI and large models redefine productivity and digital interaction, a key challenge emerges—how to bring the power of these models to the edge. On April 9, Quectel Communications responded with the official launch of its “Modular Audio Cloud” (Moyinyunxi) multi-modal interaction solution. This integrated hardware-software-cloud framework combines Quectel modules, AI audio algorithms, and the Feiyuan IoT platform, enabling terminal devices to tap into cloud AI big models for rich, real-time, and intelligent user experiences. Quectel’s new solution is poised to accelerate the deployment of AI large model capabilities across diverse edge scenarios, marking a significant step toward mass adoption of intelligent, multimodal interfaces in consumer and industrial IoT.
Intelligent Interaction at the Edge: Full-Stack Terminal Enablement
At the heart of the Modular Audio Cloud is a comprehensive hardware and software stack designed to support next-generation voice and video interactions on edge devices.
Hardware Capabilities:
- Connectivity Modules: 5G, LTE, Wi-Fi/Bluetooth, and smart modules by Quectel.
- Cloud AI Middleware Integration: Unified SDK to enable seamless connection to cloud AI models.
- Device Management: Easy onboarding to the QuecThing IoT platform for remote configuration and updates.
AI Audio Algorithms on Device:
- VAD (Voice Activity Detection)
- AEC (Echo Cancellation)
- ANS (Noise Suppression)
- KWS (Keyword Spotting/Voice Wake-Up)
By embedding these full-link pure-software algorithms, the solution eliminates the need for separate DSP chips, significantly reducing costs and space requirements—a crucial enabler for compact and cost-sensitive smart devices.
The solution also supports multimodal interaction, combining voice, text, images, and other inputs for more natural and immersive human-machine engagement.
Feiyuan IoT Platform: The Cloud Backbone for AI at Scale
The Feiyuan IoT platform underpins Quectel’s Modular Audio Cloud, offering a robust ecosystem for managing smart devices and deploying cloud-based AI models.
Core Platform Features:
