+# Qwen3-TTS 0.6B ONNX INT8 Quantized
+
+This repository provides **INT8 quantized** ONNX models for Qwen3-TTS 0.6B, optimized for efficient inference.
+
+## Model Details
+
+- **Original Model:** [Qwen/Qwen3-TTS](https://github.com/QwenLM/Qwen3-TTS) by the Qwen Team at Alibaba
+- **ONNX Conversion:** [zukky/Qwen3-TTS-ONNX-DLL](https://huggingface.co/zukky/Qwen3-TTS-ONNX-DLL)
+- **Quantization:** Dynamic INT8 quantization using ONNX Runtime
+
+## Compression Results
+
+| Model | Original | Quantized | Compression |
+|-------|----------|-----------|-------------|
+| talker_prefill | 1.69 GB | 448 MB | 75% |
+| talker_decode | 1.69 GB | 448 MB | 75% |
+| text_project | 1.21 GB | 317 MB | 75% |
+| tokenizer12hz_decode | 436 MB | 221 MB | 52% |
+| code_predictor | 420 MB | 111 MB | 75% |
+| tokenizer12hz_encode | 184 MB | 76 MB | 61% |
+| code_predictor_embed | 120 MB | 31 MB | 75% |
+| speaker_encoder | 34 MB | 9.3 MB | 73% |
+| codec_embed | 12 MB | 3.1 MB | 75% |
+| **Total** | **6.1 GB** | **1.6 GB** | **73%** |
+
+## Usage
+
+### Requirements
+
+```bash
+pip install onnxruntime numpy
+```
+
+### Loading Models
+
+```python
+import onnxruntime as ort
+
+# Load a quantized model
+session = ort.InferenceSession(
+    "text_project_q.onnx",
+    providers=["CPUExecutionProvider"]
+)
+
+# Run inference
+outputs = session.run(None, {"input_ids": input_ids})
+```
+
+### Full Pipeline
+
+For the complete TTS pipeline, you'll need:
+1. The tokenizer files from [Qwen3-TTS-12Hz-0.6B-Base](https://huggingface.co/zukky/Qwen3-TTS-ONNX-DLL/tree/main/models/Qwen3-TTS-12Hz-0.6B-Base)
+2. The Rust DLL for audio preprocessing (from the original repo)
+3. Reference audio for voice cloning
+
+See the [original repository](https://huggingface.co/zukky/Qwen3-TTS-ONNX-DLL) for the complete pipeline example.

+## Test Results (Linux, ONNX Runtime 1.23.2)
+
+| Model | Status | Notes |
+|-------|--------|-------|
+| text_project_q.onnx | ✅ Works | Text → embedding |
+| codec_embed_q.onnx | ✅ Works | Code embedding |
+| code_predictor_q.onnx | ✅ Works | Sub-code prediction |
+| code_predictor_embed_q.onnx | ✅ Works | Code predictor embedding |
+| talker_prefill_q.onnx | ✅ Works | Initial generation |
+| talker_decode_q.onnx | ✅ Works | Autoregressive decoding |
+| speaker_encoder_q.onnx | ⚠️ Fails | Requires ConvInteger support |
+| tokenizer12hz_encode_q.onnx | ⚠️ Fails | Requires ConvInteger support |
+| tokenizer12hz_decode_q.onnx | ⚠️ Fails | Requires ConvInteger support |
+
+## Known Limitations
+
+- **ConvInteger ops**: The audio tokenizer and speaker encoder models use `ConvInteger(10)` ops that require:
+  - ONNX Runtime with MLAS optimizations
+  - Or GPU execution provider (CUDA, DirectML)
+- **Voice cloning**: Requires reference audio processing from the original DLL
+- **Full pipeline**: For complete TTS, you need the non-quantized tokenizer models from the original repo

+# Qwen3-TTS DLL + ONNX (Minimal, Single-File ONNX)
+
+This Hugging Face repository provides a **minimal** runtime bundle for Qwen3-TTS:
+- **Rust DLL** for audio preprocessing + tokenizer (BPE)
+- **ONNX** models (single `.onnx` files with embedded weights)
+- **Minimal tokenizer files** (`config.json`, `vocab.json`, `merges.txt`, `tokenizer_config.json`)
+- **Python sample** that runs the full pipeline using ONNX Runtime
+
+**Important:** ONNX Runtime is **not** bundled. Install `onnxruntime` (CPU) or `onnxruntime-gpu`.
+

+
+## Quick Start (Python)
+
+### 1. Install dependencies
+
+```powershell
+python -m pip install numpy onnxruntime
+```
+
+For GPU:
+
+```powershell
+python -m pip install numpy onnxruntime-gpu
+```
+
+### 2. Set DLL path
+
+```powershell
+set QWEN3_TTS_DLL=.\qwen3_tts_rust.dll
+```
+
+### 3. Run (1.7B)
+
+```powershell
+python examples\python_dll_call\run_pipeline.py ^
+  --onnx-dir .\onnx_kv ^
+  --model-dir .\models\Qwen3-TTS-12Hz-1.7B-Base ^
+  --ref-audio C:\path\to\ref.wav ^
+  --ref-text  C:\path\to\ref.txt ^
+  --text "Hello world."
+```
+
+### 4. Run (0.6B)
+
+```powershell
+python examples\python_dll_call\run_pipeline.py ^
+  --onnx-dir .\onnx_kv_06b ^
+  --model-dir .\models\Qwen3-TTS-12Hz-0.6B-Base ^
+  --ref-audio C:\path\to\ref.wav ^
+  --ref-text  C:\path\to\ref.txt ^
+  --text "Hello world."
+```
+
+## CPU / GPU switching
+
+- Default: CUDA if available, otherwise CPU.
+- Force CPU:
+
+```powershell
+python examples\python_dll_call\run_pipeline.py --device cpu ...
+```
+
+## Required Files
+
+Required:
+- `qwen3_tts_rust.dll`
+- `onnx_kv/*.onnx` (or `onnx_kv_06b/*.onnx`)
+- `models/<model>/{config.json,vocab.json,merges.txt,tokenizer_config.json}`
+- `examples/python_dll_call/run_pipeline.py`
+
+Optional:
+- `qwen3_tts.h` (C/C++ bindings)
+- `onnx_kv_06b/` (only for 0.6B)
+
+## Notes
+
+- ONNX files are **single-file** (no `.onnx.data`, no `onnx__MatMul_*` shards).
+- Samples are not included. Provide your own reference audio/text.
+- First load can be slow due to large model size.
+
+## Troubleshooting
+
+- **DLL not found**: set `QWEN3_TTS_DLL` or run from this folder.
+- **CUDAExecutionProvider not available**: install `onnxruntime-gpu` or use `--device cpu`.
+- **InvalidArgument / input shape**: ensure reference audio is mono. The script will resample.
