| # Inflect-Micro-v2 TTS SDK for AX650 NPU3 | |
| Encoder-Decoder split VITS text-to-speech engine. | |
| ## Files | |
| - `inflect_encoder.axmodel` — Text encoder (NPU) | |
| - `inflect_decoder.axmodel` — Flow + HiFi-GAN decoder (NPU) | |
| - `model.pth` — Full PyTorch weights (CPU components: embedding, duration, flow params) | |
| - `config.json` — Model configuration | |
| - `tts_engine.py` — Main inference engine | |
| ## Usage | |
| ```python | |
| from inflect_tts_sdk import InflectTTSEngine | |
| engine = InflectTTSEngine() | |
| engine.warmup() # Initialize NPU sessions | |
| sr, wav = engine.synthesize("Hello world!") | |
| engine.save("Hello world!", "output.wav") | |
| ``` | |
| ## Pipeline | |
| 1. Text → Phonemes → Tokens (CPU, Python frontend) | |
| 2. Embedding lookup (CPU) | |
| 3. **Encoder NPU**: embeddings → m_p, logs_p, x_mask | |
| 4. Duration predictor + alignment (CPU) | |
| 5. **Decoder NPU**: z_p → waveform | |
| ## Requirements | |
