That is the output from the Microsoft speech recognition system. If a command is recognized, it returns the command phrase.
If you specifically require dictation output, use wildcard commands, which utilize the dictation capabilities of the speech recognition system, and as such can provide more information to the log.
The word/phrase "ice" is a very poor candidate for continuous recognition or wildcard commands though, being a very short, single-syllable word that will occur in other words, as you mention.
Continuous recognition and wildcard commands work best with longer, distinct, and unique phrases.
