Voice Call Dialer for Android is a handy utility that will help you easily make phone calls by speaking into your device's microphone. Simply speak the name of the person that you wish to call, and the app will automatically dial that contact. If more than one number appears under a contact, you will have to select the number you want to call.

To use this, you need to make sure that you have installed Google Voice Search on your device and that you have an Internet connection.
