Sistema de reconocimiento de voz mediante wavelets, predicción lineal y redes backpropagation/Wavelets, linear prediction and backpropagation networks for speech recognition system

A system that combines the use of Wavalet Transforms (WT), Linear Prediction Coefficients (LPC) and Artificial Neural Networks (ANN) are shown in this paper. Vowels and syllables recognition speaker independent can be made. Using this structure, automated software is proposed, which through an interface, allows users with hearing difficulties or total absence of this, the possibility of using it primarily as an initial tool to support learning of syllables. In the first stage, a small number of syllables is incorporated, especially those that may have more difficulty in their identification. Subsequently, it can be incorporated a larger number of syllables, then it can be growing. Adding new syllables, would allow (through segmenting words into syllables) a greater deployment system, for identifying complete words and therefore the spoken language learning.
