Android: When you're typing on a smartphone, you can double-tap a word to correct a mistake. Google Voice search is no different: if it misunderstands a word, you can say it again without repeating your entire phrase.
Google Voice Search is actually really good at understanding me, but every once in a while it will get something wrong. There are two fixes:
- Tap the word, and it will show a few other possibilities. If none of those are right, tap the Respeak button to say the word again out loud.
- If you're going completely hands-free (and your phone supports it), you can say "OK, Google" again and then say "No, I meant ____". It will replace the correct word into your last search, which is pretty awesome.
Hopefully that will help you the next time Google corrects "Lifehacker" to "life jacket".
