Earlier quoted context omitted.
The French version is a little contrived. The speaker is a native speaker, but the text is obviously the result of a translation from English to French, not idiomatic French. I will try to put the code to the test, see how it goes.
Interesting, I'm a non-native French speaker, the original French piece struck me as being entirely normal (but maybe it was just the perfect French accent that swayed me). Can you please point out what he said which wasn't idiomatic or naturally-worded French?
> Nous établissons que l'utilisation de données d'un tel nombre et d'une telle diversité est la raison pour laquelle le système est à même de comprendre de nombreux accents...
It doesn't sound natural at all. An idiomatic formulation would be more along the lines of:
Le recours à un corpus [de données] si riche et varié est ce qui permet au système de comprendre de nombreux accents (With 'corpus', 'données' is implied.)
Of course this is just an example, and I'm sure other French speakers could come up with a different wording, but "données d'un tel nombre et d'une telle diversité" sounds really wrong.
This is also weird and convoluted:
> Nous distribuons en tant que logiciel libre le code source pour nos modèles et pour l'inférence, afin que ceux-ci puissent servir comme un point de départ pour construire des applications utiles
It should at least be "le code source DE nos modèles" and "servir DE point de départ", and "en tant que logiciel libre" should placed at the end of the proposition (after 'inférence').
Also, "construire" isn't used for code but for buildings, and "applications utiles" is unusual, because "utiles" (useful) is assumed. "...pour le développement de nouvelles applications" would sound more French.
