A portable radiotelephone with an integral voice recognition circuit is disclosed. Control of the voice recognition circuit is achieved with a foldable housing element which, in a closed position, covers an external keypad and control buttons. When the foldable housing element is in an open position, the portable radiotelephone is placed in an off-hook condition, the voice recognition circuit is activated, and the acoustic transducers are coupled to the voice recognition circuit. When the foldable element is in a closed position, the portable radiotelephone is placed in an on-hook condition, the voice recognition circuit is deactivated, and the electroacoustic transducers are coupled to the radiotelephone. A rapid closing and opening of the foldable element results in the voice recognition circuit being deactivated while the portable radiotelephone remains in the off-hook condition.
A portable radiotelephone apparatus having a voice recognition circuit and further having a housing with a movable member and a fixed member having an earpiece electroacoustic transducer disposed therein, the movable member having a contracted first position and an extended second position, the portable radiotelephone apparatus comprising:
A method of control of a voice recognition circuit in a portable radiotelephone apparatus having a keypad disposed on an outer surface and a movable member which covers the keypad when the movable member is placed in a first position and which exposes the keypad when the movable member is placed in a second position, comprising the steps of:
