Thanks for the comment! The main difference is the use of speech instead of text. At school, I could read/write in French, but then was absolutely lost speaking to French people. If you want to speak a language, you have to speak it. The fluency score is also quite useful for tracking your progress. I tried to get ChatGPT to give a fluency score, but it simply couldn't do it so I had to build some software to create a fluency score using rate of speech and the number of unique words you use.
