Using an English or French presentation to a French talk? I'll be defending my Ph.D. this October. I submitted my dissertation in English and prepared an English presentation, but my supervisor along with the jury members surprised me by saying the defense speech cannot be in English and must be in French (“since we are from a country that has the second language is French”). Actually, they don’t mind an English report. In fact, they are very proud of the report. 

So my question is, what would be suitable in this situation, keep the presentation in English and talk in French, or, I will change the presentation to French since I talk in French?
I would put the presentation into French, for two basic reasons:


just to make sure that when you glance at the screen any word triggers a train of thought in French
the audience also has the French ppt to look at matching what they hear from you.


I understand that the thesis is in English, but they won't necessarily open that until after depending on the questions - which they have probably already prepared...

Also, anytime I have to listen to one language and read a second (and I have a DUT to go with my BEng Hons) I always change to comparing the errors in expression / translation and loose the real message.

So, go with French ppt &amp; language and BEST OF LUCK - you will be fine.

Autrement dit : Bonne chance Chef !!
