ABSTRACT:
A system for recognizing spoken text includes a microphone for converting spoken text uttered by a speaker into analog electrical signals. An analog to digital converter to convert the analog spoken text data into digital electronic signals. A speech recognition device uses a lexicon data device; a language model data device; and a reference data device to convert the digital spoken text into recognized text data. The system also includes a keyboard for entering error correction data and an error correction device which generates corrected text depending on the corrected text. Adaptation apparatus of the lexicon data device and adaption apparatus of the language model data device, adapt the lexicon data and the language model data respectively to the speaker depending on the corrected text. Then a second speech recognition process is carried out by the speech recognition device depending on the original spoken text, the adapted lexicon data and the adapted language model data to generate newly recognized repeated text which is transmitted to the reference data device. Adaption apparatus of the reference data device or speech recognition device, adapt the reference data to the speaker depending on the recognized repeated text.
