ABSTRACT:
An apparatus for recording speech for subsequent generation of a text includes an acoustic input (M) and an acoustic output (L) for inputting and outputting analog speech respectively. An analog-to-digital/digital-to-analog (AD/DA) converter converts the inputted analog speech into a digitized speech and converts digitized speech into analog speech. A preprocessor (VV) preprocesses the digitized speech converted by the converter (AD/DA), and extracts spectral component characteristics from the digitized speech. A digital memory (MEM) stores the digitized preprocessed speech and a controller (CON) controls an execution of inputted operating functions by at least one of the preprocessor and the digital memory. The method of recording speech for subsequent generation of a text using a speech-processing system includes digitizing an input analog speech data, preprocessing the digitized analog speech data by extracting spectral component characteristics from the digitized analog speech for subsequent generation of a text by a speech recognition process, storing the digitized preprocessed speech in a digital memory, and subsequently retrieving the digitized preprocessed analog speech from the digital memory and converting the retrieved speech into a text by use of a speech-processing system that includes a speech recognition program.
