# SingingSDS: Role-Playing Singing Spoken Dialogue System

A role-playing singing dialogue system that converts speech input into character-based singing output.

## Installation

### Requirements

- Python 3.11+
- CUDA (optional, for GPU acceleration)

### Install Dependencies

#### Option 1: Using Conda (Recommended)

```bash
conda create -n singingsds python=3.11

conda activate singingsds
conda install pytorch torchvision torchaudio pytorch-cuda=11.8 -c pytorch -c nvidia
pip install -r requirements.txt
```

#### Option 2: Using pip only

```bash
pip install -r requirements.txt
```

#### Option 3: Using pip with virtual environment

```bash
python -m venv singingsds_env

# On Windows:
singingsds_env\Scripts\activate
# On macOS/Linux:
source singingsds_env/bin/activate

pip install -r requirements.txt
```

## Usage

### Command Line Interface (CLI)

#### Example Usage

```bash
python cli.py --query_audio tests/audio/hello.wav --config_path config/cli/yaoyin_default.yaml --output_audio outputs/yaoyin_hello.wav
```

#### Parameter Description

- `--query_audio`: Input audio file path (required)
- `--config_path`: Configuration file path (default: config/cli/yaoyin_default.yaml)
- `--output_audio`: Output audio file path (required)


### Web Interface (Gradio)

Start the web interface:

```bash
python app.py
```

Then visit the displayed address in your browser to use the graphical interface.

## Configuration
