+# Model Card for ku-berfin_renas-medium
+
+A multi-speaker Kurmanji Kurdish (Kurmancî) text-to-speech model trained
+with the [Piper TTS](https://github.com/OHF-Voice/piper1) framework.
+Supports two speakers — **Berfin** (speaker 0) and **Renas** (speaker 1) —
+at medium quality and 22,050 Hz sample rate.
+
+## Model Details
+
+### Model Description
+
+- **Developed by:** rojanu
+- **Model type:** VITS (Variational Inference with adversarial learning for
+  end-to-end Text-to-Speech)
+- **Language(s):** Kurmanji Kurdish (`ku`)
+- **License:** [CC BY-NC 4.0](https://creativecommons.org/licenses/by-nc/4.0/) — free for non-commercial use with attribution; commercial use restricted due to [Blizzard 2013 base model](https://www.cstr.ed.ac.uk/projects/blizzard/2013/lessac_blizzard2013/license.html)
+- **Finetuned from model:** `en_US-lessac-medium` (Piper English vocoder
+  warm-start)
+
+### Model Sources
+
+- **Repository:** [rojanu/piper-ku-berfin-renas-medium](https://huggingface.co/rojanu/piper-ku-berfin-renas-medium)
+- **Framework:** [OHF-Voice/piper1](https://github.com/OHF-Voice/piper1)
+
+## Speakers
+
+| Speaker ID | Name   |
+|------------|--------|
+| 0          | Berfin |
+| 1          | Renas  |
+
+## Uses
+
+### Direct Use
+
+Offline, on-device Kurmanji Kurdish speech synthesis. Designed for:
+
+- Screen readers (e.g. NVDA with the [piper-nvda addon](https://github.com/mzanm/piper-nvda))
+- Assistive technology
+- Voice interfaces for Kurdish-language applications
+
+### Out-of-Scope Use
+
+- Languages other than Kurmanji Kurdish
+- High-fidelity / broadcast-quality synthesis (this is a medium-quality model)
+
+## How to Get Started with the Model
+
+### With Piper CLI
+
+```bash
+echo "Silav û rêz ji hemûyan re." | piper \
+  --model ku-berfin_renas-medium.onnx \
+  --speaker 0 \
+  --output_file output.wav
+```
+
+### With NVDA
+
+Install the [piper-nvda addon](https://github.com/mzanm/piper-nvda) and use
+the direct download URL:
+
+```
+https://huggingface.co/rojanu/piper-ku-berfin-renas-medium/resolve/main/ku-berfin_renas-medium.tar.gz
+```
+
+## Training Details
+
+### Training Data
+
+A private dataset of two Kurmanji Kurdish speakers (**Berfin** and **Renas**),
+approximately 2.72 hours total (1.32h Berfin, 1.40h Renas), recorded at
+22,050 Hz.
+
+| Speaker | Files | Duration  |
+|---------|-------|-----------|
+| Berfin  | 1,022 | 1.32 hours |
+| Renas   | 1,024 | 1.40 hours |
+| **Total** | **2,046** | **2.72 hours** |
+
+### Training Procedure
+
+#### Preprocessing
+
+- Audio normalised to 22,050 Hz mono WAV
+- Text phonemized via `espeak-ng` with voice `ku`
+- Average utterance duration: ~4.79 seconds
+
+#### Training Hyperparameters
+
+- **Training regime:** fp32
+- **Framework:** Piper / PyTorch Lightning
+- **Base checkpoint:** `en_US-lessac-medium` (vocoder warm-start)
+- **Batch size:** 32
+- **Max epochs:** 929 (training stopped; best validation at ~epoch 72)
+- **Hardware:** AMD ROCm GPU
+- **Validation split:** 5%
+
+## Evaluation
+
+### Results
+
+The model shows signs of overfitting due to the small dataset (~2.7h total).
+Best validation loss was achieved at approximately epoch 72. Audio quality is
+intelligible but benefits from additional training data.
+
+**Known limitations:**
+- Dataset too small for high-quality multi-speaker TTS (recommend ≥ 3h per speaker)
+- Overfitting observed after epoch ~72
+
+## Technical Specifications
+
+### Model Architecture
+
+- **Architecture:** VITS medium
+- **Sample rate:** 22,050 Hz
+- **Phoneme type:** espeak (`ku`)
+- **Number of speakers:** 2
+- **Model size:** ~77 MB (ONNX)
