PowerPoint spellchecker checks the spelling of
entire presentation including all slides,
outlines,
notes pages,
handout pages.
Correction in two different ways:

If you see wavy red line under a word:
right-click the word and choose the correct spelling from the list.
PowerPoint style checker works with the Office Assistant to help correcting common presentation style mistakes:
incorrect font size,
inconsistent punctuation,
other readability problems.
