Software toolkit for testing of speech signals processing systems. Part 2. Efficiency estimation
Main Article Content
Abstract
Structure of the software toolkit for the study and optimization of algorithms of correction and coding systems, which are subject of various distortions, such as noise and reverberation disturbance, coding errors is proposed. The first part of this paper was devoted to consideration of toolkit which permit solve such problems as creating of noisy speech corpora and correction of noisy speech signals. Software toolkit for the validation of test systems for processing speech signals using criteria such as the quality and intelligibility of speech, the accuracy of automatic speech recognition, was proposed in the second part of the work. A developed software toolkit is not uniform: some calculations done in an environment Matlab, and some - outside of this environment. Despite the specified feature, this toolkit allows user to combine all necessary software components, which provides through automation of the processing of speech signals from their deliberate distortions, subsequent correction - to evaluation of quality of the reconstructed speech signal.
