MY PREFERENCE: I would like to tell youmention another thing about my difficulty withdifficulty I have had when speaking English.

It was explained to me by one of my studentsALSO POSSIBLE: One of my students recently explained this point to me recently.

I preference because the focus is clearer.

He's a guy from the US who lives in Paris and studies inat INALCO, which is considered a very famous university for people learning “oriental” languages.

This guy hasALSO POSSIBLE: This guy seems to have an amazing capacity for learning languages.)

SUGGESTION: The hedge is better because we do not sure for sure.

BETTER: In his article, he talks aboutmentioned another article he read.

NOTE: The phrase "talks about" is good when *speaking.* When *writing* "mention" is a better word choice.

It'sHe wrote about the specificuliarities of Floridaian English.

COMPARE: (A) Floridia ➔ nound (B) Floridian ➔ adjective

He explainsed that Spanish is a “syllable-timed” language, whereas English is a “stress-timed” language.

Besides, aAccording to the article he read, Spanish would havehas influenced English in Florida in a way thatthe Floridian dialect to makes it “more syllable-timed”.

It's not in the essence ofThis characteristic is not in common in French prosody.

I'm not sure what the "besides" is trying to communicate here ("besides" used in this way is usually in the context of trying to convince someone of something) . Maybe you mean "however"?

Of course, I'm familiar with the fact that some syllables can be contracted like in French “j'suis” or “t'as” but when that happens in French, I think it's some kind of informal speaking convention, to the extent that we've got a specific spelling for that.

It's not inpart of the essence of French prosody.

"in" makes it sound like it's floating in the essence, like how you might say an ice cube is in a glass of water. "part of" says more explicitly says that it is that thing, but only a part. Hopefully that make sense.

Hopefully that makes sense. I can't really give a concrete explanation for why "in" doesn't sound quite right to me.

Besides, aAccording to the article he read, Spanish would havehas influenced English in Florida in a way that makes it “syllable-timed”.

C'est la seule partie qui ne me semble pas idiomatique.

« Besides » signifie « en plus » ou « de toute façon ». Il est utilisé pour exprimer que même si ce qui précède ne suffit pas, ce qui suit l'est. Mais dans votre cas, ce qui précède « Besides » est une information générale, et ce qui suit est le but de l'article. Cela ne sert donc à rien d’utiliser « En plus ». Il est naturel de simplement dire le point après les informations contextuelles.

Concernant "would have" vs "has", il me semble beaucoup plus probable que l'article parle de quelque chose qui s'est déjà produit. Dans ce cas, nous parlons de ce qui « has happened (according to the article) ». Dire « would have » implique que vous pensez que l'article est faux.

It's not in the essence of the French prosodyspeaking rhythm.

The original sentence is correct, but "prosody" is not a commonly used word, it's easier to understand with a word like "rhythm".

He's a guy from the US who lives in Paris and studies inat INALCO, which is a very famous university for people learning “oriental” languages.

It's about the specificities of Florida English.

you could also say "particularities"

"specificities" doesn't exist as far as I know

That means that in Spanish the intervals between two syllables are relatively equal whereas in English oneyou would rathernormally speak with equal intervals between two stresses, instead of two syllables.

"rather" makes it sounds like a conscious preference

also "one" is very rarely used as a pronoun, it's almost always "you". You could also say "we" here if you wanted to include yourself as an english speaker, and with this high quality of text, you can! :-)

Besides, aAccording to the article he read, Spanish wcould have influenced English in Florida in a way that makes it “syllable-timed”.

I didn't understand "besides" in this context, and I couldn't think of an alternative. The sentence sounds correct to me with no word to introduce it.

Also the concept in French of using the conditional for expressing uncertainty about something doesn't really exist in English in the same way.

It's not in the essencean essential part of French prosodye.

prosody does exist I think but I don't know what it means so I would suggest not to use it except in whatever very specific circumstance it's used!
