Voice2Call

The free app that brings offline voice command to your Android device

Voice2Call is a simple app that lets you search and pick a contact from your address book.
The focus of Voice2Call is solely on search, making the contact picking action as fast and hands-free as possible. To that end the app employs search-by-voice. Voice2Call can be launched by tapping its launcher icon. Once launched the list of names in your address book is shown together with information on when and how much they have been contacted. This list is sortable by various parameters.
If the name was selected by tapping, then the action depends on the corresponding setting which can be set via the Settings-menu. In case of a voice command the action depends on the command.

CALL - dial the default number and hit the call button
DIAL - just dial the default number
VIEW - launch the contact viewer (which lets you then choose a number to call, send an SMS, etc.)
