Are they confusing him with George VI and his stammer?
That's interesting about the actors being used, although if it's true, that's very disappointing!
Unfortunately in my opinion the speech of Nicholas II to President Emile Loubet which one can find on youtube does not feature the real voice of Nicholas II. I have tried in vain to find another recording of Emile Loubet to confront this one through the voice of Emile Loubet - failing to be able to do this with Nicolas II’s voice - but unfortunately it seems that there is none either.
Anyway :
- I don’t doubt for a moment that Nicolas II indeed spoke in French during this speech, but on the recording, the voice does not have the slightest Russian accent: the one attributed to Nicholas II rolls even less the "r" than the one attributed to the French President. I do not know how much Nicolas II mastered the French accent, but whereas it is certain that he was fluent, I doubt that he spoke it like the voice on the recording, which sounds too French.
- It seems that there is no break between the first voice saying "Discours du Tsar et réponse de M. Loubet à la revue de Krasnoe" and the supposed voice of the Tsar. Even more suspicious: the voice doesn’t seem to change. Yet during the real event, it is obvious that the speech was not announced like this (still less by the Tsar himself).
- The absence of background sounds during the speeches seems to me suspicious, as well as the intonations, which, if the voices are rather high, do not seem to me to be the same as those one would have in front of a large audience.
- Moreover, the voice is not the same as the other available recording where he addresses his troops in Russian, and whose voice, in my opinion, is better suited to the one I imagine to be his.
Listening to this recording the first idea that came to me was that the speeches had been recorded after the event by French people (journalists or actors) for public distribution. It seems that this idea was also raised by someone else on this forum, so for me there is no longer any doubt.
