Key features:
- Pre-training: Transform single-channel audio into discrete tokens for next-token prediction
- SFT: Novel "next-token-pair prediction" objective for natural conversation comprehension
- Result: More natural and fluid spoken interactions compared to baseline approaches

## Installation

```bash
git clone https://github.com/Chaos96/NTPP.git
cd parrot
python -m venv venv
source venv/bin/activate  # On Windows, use `venv\Scripts\activate`
pip install -r requirements.txt
```

## Usage

1. Prepare audio data for pre-training and fine-tuning
2. Pre-train: `python pretrain.py --input_data path/to/single_channel_data`
3. Fine-tune: `python finetune.py --input_data path/to/double_channel_data`
4. Inference: `python inference.py --input_audio path/to/input.wav`
