I'd be willing to bet a few francs that the experts in France could get the info out a bit more quickly than that ...
The raw data can be read very quickly. To compile and render the DFDR data can take a few days if the experts have only that task to do.
The CVR is the really tough one. You have to hopefully get a sharp pilot from the carrier who speaks both the native tongue and French, and you need a second "trusted agent" also fluent in both languages to keep the pilot translator on task, so to speak.
Then, you have the non-trivial task of rendering a correct English translation.
