Q: voice recognition not dictation but open and close apps get time seems to have gone in yosemite is this the case or is it there somewhere?

I have two questions re voiceover and yosemite,

1, has voice recognition to open, close apps and the clock etc. been removed ?

2. when reading a pages documents I seem to have lost the ability to navigate by paragraph a great facility for skip reading and back searching. Has this been removed?

Can anyone advise.
