This fantastic piece of software – Siri, is a virtual assistant with a voice-controlled natural language interface that uses sequential inference and contextual awareness to help perform personal tasks for iOS users.
There are just a couple of drawbacks.  The almost constant requests to update iOS can sometimes stop you from using your phone to make simple calls, send mail and texts.  The other is that Siri does not always get the pronounciation right with names.  This is not a problem for me – I like it when my surname is pronounced in 2 syllables as Parkez instead of the one syllable Parkes.  Others are not so keen.  Barbara Striesand had to point out to the H/O Apple that her surname is pronounced “Streisand with a soft ‘s’ like sand.  Tim Cook has agreed to change the pronunciation on the next update.
