In this paper, the automatic speech recognition task has been presented. Used toolkits, libraries and prepared speech corpus have been described. The obtained results suggest, that using different acoustic models for normal speech and whispered speech can reduce word error rate. The optimal training steps has been also selected. Thanks to the additional simulations it has been found that used corpus...
This paper presents results of our research on automatic telephone call speaker recognition. A significant improvement of recognition quality can be observed if we use the knowledge on how the original speech was coded, e.g., using GSM or PCM telephone standard. On this basis we can improve the quality of the speaker models. In order to realize such a speech analyzer we propose to analyze the mean...
W artykule opisano metodę przydatną do wykorzystania przy rozpoznawaniu samogłosek wypowiadanych przez osoby pozbawione krtani. W tej metodzie zastosowano analizę ruchu markerów umieszczonych na twarzy mówcy. Ruch markerów rejestruje się cyfrową kamerą wideo i analizuje za pomocą opracowanego oprogramowania.
In this paper an algorithm for detection of endpoints of isolated words, which is a part of the automatic speech recognition (ASR) system, is presented. Our algorithm is based on the Legendre (slope) transformation. In order to analyze an influence of the proposed algorithm on the recognition effectiveness, a set of 10 Polish steering words was tested in two characteristic cases: recognition of original...
