This invention relates to a unitary hand held medical prescription transcriber and printing unit. More specifically, a small, portable electronic device is provided which can record words spoken by a physician and from those words generate a printed medical prescription that is delivered directly from the device itself. The unit digitizes words spoken by the user, processes the speech to recognize the words spoken by comparing the acoustic spectral characteristics of the spoken words to the characteristics of a database of known words, formats those words in the form of a prescription, and prints the prescription onto paper using a small integral printer contained in the unit. In a alternate embodiment, the unit may display the prescription on a liquid crystal display screen and the user may edit the prescription before printing a hard copy. The unit assists in accurate dispensing of medicines by providing a legible prescription printout, while at the same time being neither time consuming nor difficult to operate.
