Computer voice response and computer speech recognition can provide a valuable supplementary training aid for military training systems. For training devices based on media or software which is hard to change, voice can provide supplementary information and allow spoken amendments to course information. For simulators which attempt physical fidelity to a particular defense system, speech provides a medium which can communicate information to and from the student without interfering with the defense system displays or controls.
It is feasible to add computer voice response of telephone quality to most training systems. Such voice response can be entered and changed by simply speaking into a microphone. At least thirty minutes of such speech can be stored and retrieved digitally in a simple hardware implementation.
Speech recognition capability can add a further dimension to a voice training aid, allowing the trainee to make requests or to answer multiple-choice questions.
