Abstract

The invention is a modular pen-type speech input device for use with personal computers, palm top computers, personal digital assistants, wearable computers, desktop computers or other general purpose computers. The invention consists essentially of a pen shaped device with integral microphone, rechargeable power supply, wireless transmitter and a plurality of function modules. These modules can be selectively removed or added depending on the desired function set of the user.
