PreVox™ Neural RT-20 is a real-time neural noise cancellation and speech enhancement solution for embedded systems, designed as a pre-processor for vocoders. It delivers maximum speech quality while maintaining real-time latency, ensuring cleaner input for any voice codec.

• Hybrid streaming neural core (dual-branch: spectral + time-domain).
• Vocoding pre-processor: improves codec efficiency by feeding it with cleaner speech.
• Low latency. Typically 20–40 ms algorithmic delay (configurable).
• Higher quality. Cleaner speech in stationary & non-stationary noise; no “musical noise,” natural prosody retained.
• Customer retraining. We adapt the model to your noise profiles and device acoustics.
• Optimized for ARM & DSP. Runs on ARM (Cortex-A/M/R, NEON) and common DSP cores (e.g., TI).
