| description |
In spite of the advances accomplished throughout the last few decades, automatic
speech recognition (ASR) is still a challenging and difficult task when the systems
are applied in the real world. Different requirements for various applications drive
the researchers to explore for more effective ways in the particular application.
Attempts to apply artificial neural networks (ANN) as a classification tool are
proposed to increase the reliability of the system. This project studies the approach of
using neural network for speaker independent isolated word recognition on small
vocabularies and proposes a method to have a simple MLP as speech recognizer. Our
approach is able to overcome the current limitations of MLP in the selection of input
buffers’ size by proposing a method on frames selection. Linear predictive coding
(LPC) has been applied to represent speech signal in frames in early stage. Features
from the selected frames are used to train the multilayer perceptrons (MLP) feedforward
back-propagation (FFBP) neural network during the training stage. Same
routine has been applied to the speech signal during the recognition stage and the
unknown test pattern will be classified to one of the nearest pattern. In short, the
selected frames represent the local features of the speech signal and all of them
contribute to the global similarity for the whole speech signal. The analysis, design
and the PC based voice dialling system is developed using MATLAB®. |
