Resumen:
In this study a new approach to the front-end stage of an automatic speech recognition (ASR) system is introduced. One dimension, which takes into account nonlinearities and dynamical changes of speech signal by means of the evaluation of a complexity measure, is added to a classical homomorphic speech analysis. We contrast the performance of a classical ASR system front-end and the ones obtained including these information measures in the presence of additive nois
