"frowny face" also works to give you :-(

Maybe this has already been mentioned...? But if you 'say' the Smiley face that you want Siri to use, 'she' will also create it that way. Found here: http://wp.me/p1UUI0-2p

You can also say "frowny face" for the sad face one which I think is adorable...

Unfortunately for those who would prefer a feature/ability not exist that they don't have to use in the first place, Siri (/Nuance Dictate) already supports/recognizes at least some of the more common abbreviations, like LOL, LMAO, BRB, and BBQ (which could also be barbecue, anyway).

Back to emoticons, since Siri doesn't recognize things like "kiss face", you can still use them by speaking the punctuation, like "colon hyphen asterisk" for the :-* kiss face, or "colon hyphen cap P" for :-P (saying "cap" before a word or letter capitalizes it). The only thing to watch out for, when dictating a smilie after a word, is that speaking a colon after a word will /not/ insert a space between the word and the colon, as there isn't supposed to be in normal writing. I haven't been able to get the "space bar" command to work, which is what turns a hyphenated word into two separate words.

"[crarko adds: I haven't tested this one. Hopefully Siri will never learn LOL-speech.]"

LOL

sorry couldn't resist.
