I watched a video on https://www.quora.com/How-do-you-pronounce-JSON and read some sites, but don't understand, what letter is emphasized (accentuated, stressed): jAy sawn or jay sAwn?

    I mean, I pronounce it like the name 'Jason', but I think this would be better on a relevant tech SE.

  • You could probably make this a better fit for this site as opposed to, say, Software Engineering by adding what answers on Quora said about how to pronounce it, especially the weird-looking IPA transcriptions, and how you're still struggling with that. Feb 6, 2019 at 19:25

    always imagined it was "JAY-sawn", "The end is like the O in on", (from reddit.com/r/javascript/comments/2mapkc/how_to_pronounce_json )

    Personally, I say "jay-Sahn", with equal stress, and the second syllable rhymes with "con", not "lawn".

    I first started using JSON in a team that included a guy named Jason (and the Cot-Caught merge is typical in the local dialect), so we all definitely stressed the second syllable to reduce confusion with the name. Jun 5, 2020 at 12:17

Most often jay-suhn, like the name and the video, or jay-sawn, emphasis on the second syllable.

Lately, most people I've heard use the latter. I suspect to specifically differentiate it from the name.

Whatever you do, never write JASON, eeek.

  • Thanks! As I understood, in most cases second syllable is emphasized. I didn't know, whether it was most common.
