Parametrizaciones robustas de Reconocimiento Automático de Habla (RAH) en redes de comunicaciones

Diego Ferney Gómez Cajas, Franklin Alexander Sepúlveda Sepúlveda, Mario Augusto Pinto Serrano


In this paper we address the problem of Automatic Speech Recognition (ASR) when the speech signal has been transmitted over communications networks. In these conditions, the main causes of distortion in an ASR system are ambient noise, transmission errors and the encoding-decoding process [32]. In the literature we are able to find multiple solutions for this problem, from different points of views; however,in this paper we will focus the analysis on solutions with robust parameterizations for the above distortions.
