AI Speech Engine
Built on NEU NLP Lab's in-house research, we re-architected the ASR pipeline from the traditional AM+LM+Decoder cascade into an end-to-end (E2E) neural model. Using Conformer + CTC/Attention hybrid modeling, combined with INT8/INT4 quantization, pruning, knowledge distillation, structural re-parameterization, and operator fusion, the engine achieves real-time ASR on CPU alone — no GPU required. Lightweight language modeling with adaptive context compression reduces LM compute by over 70%, while recognition accuracy improves 10–20% over traditional approaches.
- ▸E2E model: Conformer + CTC/Attention hybrid, eliminating acoustic/language modeling error accumulation
- ▸INT8/INT4 quantization & pruning: drastically reduced params for real-time CPU inference
- ▸Knowledge distillation & structural re-parameterization: compact model with high generalization
- ▸Operator fusion & cache optimization: improved CPU matrix efficiency
- ▸Lightweight LM: internal LM + adaptive context compression, 70% compute reduction
- ▸Context-enhanced training & constrained self-attention: high accuracy in low-resource conditions

ASR × OCR Multimodal Fusion
Screen-content awareness × dynamic ASR enhancement
VoiVision links ASR with on-device OCR, using the visual content of the screen (PPT / docs / whiteboard) to boost speech recognition. The BJ66+WCB06 captures the screen via wired + wireless channels; an on-device large-model OCR reads the text frame by frame; the domain knowledge base auto-matches and injects domain terms into the ASR decoder — lifting accuracy in terminology-dense scenes like lectures, consults, and roadshows.
Four-step closed loop
- ▸① Capture: BJ66+WCB06 grabs the screen byte stream (HDMI-in + wireless)
- ▸② On-device OCR: frame-by-frame parsing of PPT / docs / whiteboard text
- ▸③ KB match: 200+ discipline hotword dictionaries auto-align
- ▸④ Hotword injection: domain terms dynamically injected into ASR decoder
Key advantages
- ✓Fully local private deploy — data never leaves room
- ✓Hot-swappable domain KBs (education / healthcare / finance / law)
- ✓New domains need no ASR retraining — hotwords take effect instantly
- ✓Hotword injection < 500ms, frame-level OCR < 500ms
