Abstract :
In this paper, we describe several important experiments concerning large vocabulary distributed continuous speech recognition (LVDCSR) systems in Brazilian Portuguese using LSF and LPC - derived features. The ITU-T G.723.1 codec is employed and investigated as a case of practical use of this technology. Results are presented for both speaker dependent and independent modes as well as the situations where the same text or different texts were used for training and testing.
