    When deployed to Gradio Spaces, this app will:
    
    1. Download required models (Whisper, LLaMA-Omni, vocoder)
    2. Start the controller
    3. Start the model worker
    4. Launch the web interface
    
    ## Notes
    - The model will be loaded automatically during deployment
    - Audio can be processed via both speech input and text input
    - The full system allows for seamless speech interaction

        # About LLaMA-Omni
        
        LLaMA-Omni is a speech-language model built upon Llama-3.1-8B-Instruct. It supports low-latency and high-quality speech interactions, simultaneously generating both text and speech responses based on speech instructions.
        
        ## Features
        
        * Built on Llama-3.1-8B-Instruct, ensuring high-quality responses
        * Low-latency speech interaction with a latency as low as 226ms
        * Simultaneous generation of both text and speech responses
        
        ## License
        
        This code is released under the Apache-2.0 License. The model is intended for academic research purposes only and may NOT be used for commercial purposes.
