Dear Aunt TUAW,
I love Siri. I'm surprised at how much I actually use it beyond the gimmicky stuff. Texting while driving (through my car's Uconnect system) is so handy.
One thing I've noticed is that when I dictate a message, add a smiley face and have her read it back to me, she says, "Have a nice day colon comma." The odd part is that she has written :-), which is colon hyphen right bracket. Is this a glitch or does a hyphen and right bracket together equal a comma? I was never good at grammatical math.
Your doting nephew,
Ah, bless Siri. She's such a changeable creature. Auntie used to love when Siri would read out "Brr, it's cold" as "Bee. Arr. Arr. It's Cold". Thanks to Apple's live data center updates, Siri now responds "Burr" instead of "Bee. Arr. Arr."
The smiley-face being read back as a colon is similar. It's simply a text-to-speech glitch that Apple may eventually improve. You can report any bugs to Apple directly using their Bug Reporter online website.
