3. On which ‘rules’ is the phonetic transcription based?


The “rules” used to binary accept or reject your phonetic transcription can be found on our website: cleanaccent.com, where you can find academic references to authors.

The choices here are based on the usages at the Sorbonne University in Paris by Jacqueline Vaissière, professor of Phonetics (La Phonétique (2011, 2015) Que sais-je ?, PUF, Paper version : https://www.puf.com/content/La_phon%C3%A9tique, digital version : https://itunes.apple.com/fr/book/la-phonetique/id1015237531?mt=11). The same choices are not uniformly done since the usages are depending :

  1. on the region (here the so-called standard French)

    • standard French “la rose” > [laʁoz]
    • south French > “la rose” > [laʁɔz]

    – Y. Scherrer, P. Boula de Mareüil, J.-P. Goldman (2015), « Crowdsourced mapping of pronunciation variants in European French », 18th International Congress of Phonetic Sciences, Glasgow.)

  2. the style (here hyperarticulated)
