Error while training alphabet, says it is missing characters

I never thought that it would bother in any way but yeah I will try with more conventional paths, you’re right.

So I am working on a Ubuntu 18.04.3 Virtual Machine with the dataset being on a shared folder so I can work with it easily with both my host and client machines.

I need the sudo command because I am targeting the dataset located in my shared folder, seen by Ubuntu as an external drive.

I mainly followed the tutorial made by elpimous_robot (TUTORIAL : How I trained a specific french model to control my robot), adapting the links and commands on purpose, and using the 2018 french audio dataset provided by CommonVoice.
