In American English, the most common filler sounds are ah or uh /ʌ/ and um /ʌm/ (er /ɜː/ and erm /ɜːm/ in British English).[7] Among younger speakers, the fillers "like",[8] "you know", "I mean", "okay", "so", "actually", "basically", and "right?" are among the more prevalent.[citation needed] Christopher Hitchens described the use of the word "like" as a discourse marker or vocalized pause as a particularly prominent example of the "Californianization of American youth-speak",[9] and its further recent spread throughout other English dialects via the mass-media.
