I have used this free service from Google a number of times with great success.  The voice recognition has been perfect in my experience.   You start by giving the name of the town you are located in, then the name of the business or a business category.  They return with up to 8 listings and you have the option to get the address, the telephone number, or you can simply be connected right away.  Use the comments area below to let us know how it works for you.  Try it!
