+Any-to-any voice conversion using TriAAN-VC (Triple Adaptive Attention Normalization,
+ICASSP 2023), exported to ONNX for CPU-first inference via the
+[vconnx](https://github.com/TigreGotico/vconnx) engine adapter.

+
+## Architecture
+
+Three ONNX components chained in sequence:
+
+1. **CPC encoder** — 5-layer strided Conv1d (160× downsample) + LSTM; encodes speech
+   to 256-dim content features at 100 Hz.  Derived from
+   [facebookresearch/CPC\_audio](https://github.com/facebookresearch/CPC_audio).
+2. **TriAAN-VC decoder** — SpeakerEncoder + ContentEncoder + BiGRU fusion +
+   TriAAN decoder + PostNet; maps CPC features + log-F0 → 80-band mel spectrogram.
+3. **ParallelWaveGAN vocoder** — WaveNet-style neural vocoder (MIT, kan-bayashi); mel
+   → 16 kHz waveform.
+
+## Files

+| `cpc_encoder_q8.onnx` | 1.8 MB | CPC encoder INT8 dynamic quantization |
+| `triaan_vc.onnx` | 266.3 MB | TriAAN-VC decoder (FP32) |

+## Parity (PyTorch vs ONNX Runtime, random input, T=50 frames)
+
+| Component | max\_abs Δ | mean\_abs Δ | Verdict |
+|---|---|---|---|
+| CPC encoder | 1.06e-05 | 1.46e-07 | PASS |
+| TriAAN-VC | 3.76e-06 | 6.39e-07 | PASS |
+| ParallelWaveGAN | 4.39e-05 | 1.19e-06 | PASS |
+
+All components pass with max\_abs < 5e-05 (well within perceptual threshold).
+
+## Usage
+
+```python
+from vconnx import VoiceCloner
+
+vc = VoiceCloner(engine="triaan")
+output_wav = vc.clone_voice(source_wav, target_wav)
+```
+
+Install:
+
+```bash
+pip install "vconnx[triaan]"
+```
+
+## Provenance
