Nothing to see here, everyone calls it ECMAScript.
"ECMAScript was always an unwanted trade name that sounds like a skin disease." - Brendan Eich [1]

Ecmascript and not E C M A script. Which makes it as easy to pronounce as JavaScript.
Is anyone pronouncing it like that?
Edit: After writing that I thought back, and now I do remember one time when somebody called the language ECMAScript when they weren't referring to the ECMA standard. I think this was the exception that proves the rule!
