Just talk to me

IN THE early days of computing, information was put into computers by flipping switches. After this came the relative sophistication of loading programs and data by means of punched cards or punched paper-tape. These were followed in their turn by such devices as the keyboard, the mouse, the trackball, the joystick, the touchpad and the touch-sensitive screen. Throughout all this, speech--the most natural, and perhaps the most effective, interface between people and computers--has remained largely neglected. Apart from some modest developments in software for desktop dictation in the 1990s, the only time most people have talked to their computers has been when cursing them.
