Source description
MP-SENet + Supervised Mixture of Experts (S-MoE) for Dual-Bandwidth Speech Enhancement
Speech enhancement model handling both Narrowband (NB, 8kHz) and Wideband (WB, 16kHz) audio using Supervised Mixture of Experts.
Based on:
- MP-SENet — STFT-domain magnitude-phase speech enhancement backbone
- S-MoE — Supervised MoE with deterministic hard gating by bandwidth metadata
Pre-trained Baseline
The official pre-trained MP-SENet baseline (from yxlu-0102/MP-SENet) is included at pretrained/g_best_vb.pt:
- Trained on VoiceBank+DEMAND, 16kHz, 100 epochs
- 2.263M params, 247 state dict keys
- No need to train baseline from scratch — S-MoE training initializes directly from this checkpoint
Training (S-MoE only)
pip install -r requirements-gpu.txt
# S-MoE training (downloads pre-trained baseline automatically)
SMOE_EPOCHS=60 BATCH_SIZE=2 GRAD_ACCUM_STEPS=2 python train.py
The script automatically:
- Downloads VoiceBank+DEMAND (~5GB)
- Pre-extracts WB/NB data into separate folders (no on-the-fly resampling)
- Downloads official pre-trained MP-SENet baseline from this repo
- Initializes S-MoE experts from baseline (shared → both WB+NB experts)
- Trains S-MoE on joint WB+NB data for 60 epochs
- Pushes trained model to HF Hub
Data Pipeline
All NB/WB data is pre-extracted to separate folders before training:
| Folder | Type | Processing | bandwidth_id |
|---|---|---|---|
original_wb/ | WB | Original 16kHz (symlinks) | 0 |
simple_nb/ | NB | 16k→8k→16k resampled | 1 |
codec_nb/ | NB | G.711 A-law/mu-law (round-robin) | 1 |
Architecture
| Component | Baseline | S-MoE |
|---|---|---|
| Total params | 2.263M | 3.587M |
| Active params (inference) | 2.263M | 2.263M (same!) |
| FFN type | Single GRU-FFN | 2× GRU-FFN experts, hard gated by bandwidth_id |
| Attention | Shared | Shared (unchanged) |
Environment Variables
| Variable | Default | Description |
|---|---|---|
SMOE_EPOCHS | 60 | Epochs for S-MoE training |
BATCH_SIZE | 2 | GPU micro-batch size |
GRAD_ACCUM_STEPS | 2 | Gradient accumulation (effective BS = BATCH_SIZE × GRAD_ACCUM_STEPS) |
PESQ_EVERY_N | 10 | Compute PESQ for discriminator every N steps (expensive) |
LR | 5e-4 | Learning rate |
EVAL_INTERVAL | 5 | Evaluate every N epochs |
BASELINE_REPO | AdityaRaikar/mpse-smoe-speech-enhancement | HF repo with pre-trained baseline |
BASELINE_FILE | pretrained/g_best_vb.pt | Checkpoint filename in repo |
