Johnny, not sure what you mean ? I presume you are referring to the pronunciation of the word 'virgule' rather than the word 'comma'..

Apologies if this response doesn't cover what you are questioning or suggesting. 

The word "virgule" is pronounced in French numbers when it represents the equivalent of the decimal point in the standard English manner of writing decimals.

If you are after a pronunciation guide - no, I don't think the word 'virgule' features here on a pronounciation or vocabulary list specifically (not one found on simple search anyway. 

Many online dictionaries now include word pronunciation - one link below - https://www.larousse.fr/dictionnaires/francais/virgule/82126 

If you are after a specific and comprehensive  course on French pronunciation, I think you might have to look elsewhere. I have used a couple, but there are many available.

I agree. Specifically, the word virgule needs to be specifically highlighted as relevant vocabulary in this exercise as well as pronunciation of currencies.
