Do the language provisions reduce the need to use standardized phraseology?
Absolutely not! In fact, the language provisions adopted in November 2003 reinforce the case for the use of standardized phraseology (See Annex 10, Volume II, paragraph 5.1.1.1). Pilots and controllers shall use ICAO standardized phraseology in all situations for which it has been specified and resort to plain language in radiotelephony communications only when standardized phraseology cannot serve an intended transmission.
