This project is inclusive of a syllable counter function, and a compound word splitter function. They can be used independently by changing the interfaces between the functions.
The compound word splitter function was provided by Gokul VSD. It uses the Python module named PyEnchant, which is compatible with Linux and only the 32 bit Python on Windows as of May 2018.
Currently, the project takes its input from a text document and gives its output to another text document. It was made as part of an assignment in Software Engineering, in semester 4 of my engineering course.
Successful output :
The Fog Index of the given text document is 9.485714285714286
