In the French speaking parts of Switzerland, when an announcement comes on the speaker says something like:
cir-key-ont, cir-key-on (in my best phonetical spelling possible)
Seems like there is a clear "t" on the end of the first phrase but it isn't pronounced on the second one.
I tried using French dictation on my device and it wrote
ce qui ont ce qu'ils ont
Which is obviously not what I'm looking for and clearly I cannot imitate the phrase for the life of me.
