Google Voice Search app for smartphones and computers

This is a great tool.    Although Google will prompt us when we enter an incorrect spelling of a word,  there are times when I have no idea how something is spelled, although I know how to say it.     For ESL learners with reasonably good pronunciation but terrible spelling, this is also helpful.   It will also inform you about the quality of your pronunciation.   If it understands you, then your pronunciation can't be all that bad.   Definitely a must have free app for smart phones and other mobile devices.  Read out it here.
