To maybe be more clear: you are implying that the c in "soc" is pronounced like a "sh" when it's the t in "tion".

Is it not? How do you pronounce it?

Also I'm pretty sure that's what the "ʃən" at the end of the pronunciation thing means.

Looking at the sound-by-sound pronunciation, it seems to confirm this.

/ʃ/ as in she

/ən/ as in sudden

I think the question was whether or not people pronounce the "soc" in "soccer" the same as they pronounce it in "association" ("soʃ" I guess), or like "sock"
