Abstract
A mobile telephone system and a method for answering a mobile telephone incoming call by a user's verbal command, to allow hands-free voice. The mobile telephone system includes a carkit and a mobile telephone. The mobile telephone has a programming key for pre-programming the user's voice greeting, a keypad for answering the call in telephone mode, a microphone for entering a user's verbal command for answering the call in carkit mode, a digital processor connected to the microphone for performing spectrum analysis and feature extractions of the user's verbal command in carkit mode, and a memory connected to the digital processor, having a database for storing the user's pre-programmed voice greeting digitized speech pattern. The pre-programmed voice greeting may be a factory-programmed voice greeting or the user's pre-programmed voice greeting, if previously initialized after pressing the programming key. The digital processor performs spectrum analysis and feature extractions of the user's verbal command for determining if a match exists between the user's verbal command and the stored user pre-programmed voice greetings. The digital processor also checks whether the user's verbal command reaches a pre-programmed pass/fail voice threshold level, if a match is confirmed.
