Update ElevenLabs API Integration, Enhance Security, and Improve Narrator Functionality

[mgennings]

Overview

This pull request updates the integration with the ElevenLabs API to reflect the latest changes and enhances the overall functionality of the Narrator project. Significant improvements have been made to both narrator.py and capture.py to ensure compatibility with the new API version and to optimize the performance and readability of the code. Additionally, this pull request introduces significant improvements to the way environment variables and API keys are handled in the Narrator project. By implementing a .env file approach, we enhance the security and maintainability of the application.

Changes Made

1. Updated ElevenLabs API Integration:

   • Refactored narrator.py to use the new ElevenLabs client instantiation method.
   • Replaced deprecated set_api_key and get_api_key methods with the new ElevenLabs class instantiation.
   • Modified the play_audio function to handle the audio generator correctly, gathering audio data into a bytes-like object before writing it to a file and playing it.

2. Enhanced narrator.py:

   • Added detailed docstrings and comments to improve code readability and maintenance.
   • Ensured that the OpenAI client uses the correct API key and updated the image analysis to handle responses accurately.
   • Improved error handling and logging for better debugging and reliability.

3. Optimized capture.py:

   • Ensured the frames folder is created if it doesn't exist.
   • Updated the webcam initialization check and added a wait time for the camera to adjust light levels.
   • Adjusted the image resizing logic to improve performance before saving the frame.
   • Added detailed print statements and comments for clarity and debugging purposes.

4. Enhanced Security:

   • Updated narrator.py to load API keys and other sensitive information from a .env file using the python-dotenv package.
   • Modified requirements.txt to include the python-dotenv package.
   • Revised the README file to provide clear instructions on setting up and using the .env file for managing environment variables.

Benefits

• Compatibility: The code is now compatible with the latest ElevenLabs API, ensuring continued functionality.
• Performance: Optimized image processing and audio generation for better performance.
• Readability: Enhanced code readability and maintainability through detailed comments and improved structure.
• Security: The .env file method prevents sensitive keys from being hard-coded into the script or inadvertently pushed to the repository.
• Convenience: Developers can easily set up their environment by updating a single file.
• Flexibility: This approach simplifies the process of changing and managing API keys without altering the main codebase.

Additional Notes

• The .env file is included in .gitignore to ensure that personal API keys are kept private.
• Instructions in the README have been updated to guide new users through the process of setting up their .env file.

Closing Previous Pull Request

The previous pull request titled "Enhance Security: Implement .env for API Keys #44" will be closed as the changes in this new pull request supersede the previous updates and provide a more comprehensive solution.

Looking forward to feedback and suggestions on these enhancements.
