Bothlent RDM-Lite-X1 AI Voice Interaction Module

RDM-Lite-X1 combines a sound card and Android mainboard in one voice-interaction module for AI robots, intelligent voice terminals, and industrial IoT systems. It uses a microphone array and a 6 TOPS NPU to support 1-5 m interaction, 180- or 360-degree sound-source localization, directional pickup, environmental sound classification, multi-speaker separation, and 0.3-second wake-up. It connects to Doubao, Coze, Qwen, Tencent Hunyuan, and MiniMax, supports secondary Android application development, and adds visual detection to acoustic processing through the AVSS multimodal approach.

Bothlent TS-USB Sound-Card Human Interaction Module

The TS-USB is an integrated voice-interaction module from Bothlent for humanoid robots, digital-human terminals, service terminals, and AIoT devices. It supports 6-microphone 360-degree or 4-microphone 180-degree sound-source localization, uses a 60-degree pickup beam and echo cancellation to suppress environmental and loudspeaker interference, and provides accurate speech recognition at 1-2 m in noisy settings or 3-5 m in quiet settings. The USB plug-and-play module connects to Doubao, Qwen, and MiniMax models and supports industry knowledge bases plus multimodal interaction that combines visual detection with acoustic noise reduction.
