French of France
French of France is the predominant variety of the French language in France, Andorra and Monaco, in its formal and informal registers. It has, for a long time, been associated with Standard French. It is now seen as a variety of French alongside Acadian French, Belgian French, Quebec French, Swiss French, etc. In overseas France or Corsica, it is more often called Metropolitan French or Hexagonal French.
In Paris, nasal vowels are no longer pronounced as in traditional Parisian French: /ɑ̃/ → [ɒ̃], /ɛ̃/ → [æ̃], /ɔ̃/ → [õ] and /œ̃/ → [æ̃]. Many distinctions are lost: /a/ and /ɑ/, /ɛ/ and /ɛː/, /ø/ and /ə/, /ɛ̃/ and /œ̃/ and /nj/ and /ɲ/. Otherwise, some speakers still distinguish /a/ and /ɑ/ in stressed syllables, but they pronounce the letter "â" as [aː]: pâte [paːt].
In the south of France, nasal vowels have not changed; they are still pronounced as in traditional Parisian French: enfant [ɑ̃ˈfɑ̃], pain [pɛ̃], bon [bɔ̃] and brun [bʁœ̃]. Many distinctions are lost. At the end, the majority of southern speakers distinguish /e/ and /ɛ/: livré and livret are both pronounced [liˈvʁe]. In closed syllables, they no longer distinguish /ɔ/ and /o/, also /œ/ and /ø/: notre and nôtre are both pronounced [nɔtʁ̥] and jeune and jeûne are both pronounced [ʒœn]. The distinction of /a/ vs. /ɑ/ and /ɛ/ vs. /ɛː/ are lost. Older speakers pronounce all the "e": chaque [ˈʃakə] and vêtement [ˈvɛtəmɑ̃].
In the north, /a/ and /ɑ/ are both pronounced as [ɔ] at the end: là is pronounced [lɔ] and mât [mɔ].
Phonemic long vowels are still maintained: pâte [pɑːt] and fête [fɛːt]. Before /ʁ/, /a/ changed to [ɑː]: guitare is pronounced [ɡiˈtɑːʁ], voir is pronounced [vwɑːʁ].
