I mean, most Swiss French accents share common characteristics (e.g. stress on the penultimate syllable and descending intonation on the last) but having grown up near the Swiss border people there really differentiate the Genevois, Vaud, Valais accents, etc

It's not the same scale as Swiss German accents that are sometimes completely unintelligible for German speakers, but I have to admit there have been a few times I've been unable to fully understand someone speaking a thick Swiss French accent
