• scipy
• numpy

📖 Updated README

• Added Docker instructions to build and run the project

How to Run:

# Build
docker build -t animalese_translator .

docker run -v $(pwd)/output:/app/output animalese_translator

# Play the output on host
aplay output/Hello_World.wav

Why these changes?

Both projects had hardcoded local paths and no containerization support, making them difficult to run on different machines. This PR makes both projects portable and beginner-friendly with clear Docker-based setup instructions.
