Understanding the VoxCPM Pipeline: LocEnc → TTSLM → RALM → LocDiT

April 10, 2026 OpenBMB/VoxCPM ↗

The VoxCPM pipeline processes speech through four specialized neural modules: a Local Encoder (LocEnc) converts acoustic features into embeddings, a Text-to-Speech Language Model (TTSLM) jointly processes text and audio representations, a Residual Acoustic LM (RALM) refines acoustic details, and a Local DiT (LocDiT) diffuses the combined hidden states into final mel-spectrograms.

The OpenBMB/VoxCPM repository implements this novel four-stage architecture for high-f
