The speech recognition system DragonDictate-30 K is the first commercially available product for personal computers (PC) that includes a thesaurus of 30,000 words which can replace the computer keyboard completely for report writing. The system is speaker-adaptative, i.e., it can learn the phonetic pattern of the pathologist's voice. We have developed a thesaurus with special terms from the field of diagnostic pathology to shorten the time-consuming training phase. DragonDictate is compatible with all text-oriented DOS computer software tools. The recommended minimal hardware configuration is a personal computer with a 80,486 processor with 16 MB on board and a 200 MB hard disk.
