Installation

If installation seems too complicated, copy/paste this text into an AI chatbot to help you in the process.

1. Clone the repository:

   git clone https://github.com/sm18lr88/OpenAI_TTS_GUI.git
   cd OpenAI_TTS_GUI

2. Set up a virtual environment:

   • Using venv (recommended for most users):

     python -m venv venv
     # Windows
     .\venv\Scripts\activate
     # macOS/Linux
     source venv/bin/activate

   • Using uv (alternative):

     uv venv
     # Windows
     .\venv\Scripts\activate
     # macOS/Linux
     source venv/bin/activate

3. Install dependencies:

   • The dependencies are specified in pyproject.toml. Install them using:

     pip install openai pyqt6

   • If using uv, you can run:

     uv pip install openai pyqt6

Running the Application

1. Set API Key:

   • Option 1: Set the OPENAI_API_KEY environment variable.
   • Option 2: Launch the app and use API Key -> Set/Update API Key... (saves obfuscated in api_key.enc).

2. Start the GUI:

   python main.py

Tips

• Speed: Adjustments far from 1.0x may impact quality; try Adobe Audition for speed tweaks, or select the gpt-4o-mini-tts model and instruct it to speak faster/slower.
• Instructions: check examples at openai.fm.
• Security: api_key.enc is obfuscated, not encrypted, so don’t share it. Environment variable option is safer.
• ffmpeg: If not found, ensure it’s in PATH or set its path in config.py.
• Logs: Check tts_app.log for errors or details.

Roadmap

• Handles long text
• PyQt6 GUI (formerly PySimpleGUI)
• Basic API rate limit handling
• Enhance chunking and concatenation
• Option to retain chunk files
• Light and Dark themes
• Custom API key settings
• Use environment variable if set
• Code refactoring
• Basic API key obfuscation
• Speed boost: Parallel chunk processing
• Granular progress reporting
• Bundle new release into .exe
• Price estimate
