Integration of Rule-Based Systems and Neural Networks into Speech Recognition System

چکیده
The Artificial Neural Networks (ANN) were widely and successfully used in the automatic speech recognition (ASR) field, but many limitations inherent to their learning style remain. In an attempt to overcome these limitations, we combine in a speech recognition hybrid system the pattern processing of the ANNs and the logical inferencing of the symbolic approaches. In particular, we are interested by the Knowledge Base Artificial Neural Network (KBANN), approach proposed initially by G. Towell [22,23]. It consists on knowledge base implemented throughout a neural network. It is an ANN where neurons have significance and the propagation of the activation represents the inferencing process in a rule -based system. In this paper, we describe a KBANN dedicated to the Arabic speech recognition.

Although, speech recognition systems are widely used and their accuracies are continuously increased, there is a considerable performance gap between their accuracies and human recognition ability. This is partially due to high speaker variations in speech signal. Deep neural networks are among the best tools for acoustic modeling. Recently, using hybrid deep neural network and hidden Markov mo...

Speech Emotion Recognition (SER) is an important part of speech-based Human-Computer Interface (HCI) applications. Previous SER methods rely on the extraction of features and training an appropriate classifier. However, most of those features can be affected by emotionally irrelevant factors such as gender, speaking styles and environment. Here, an SER method has been proposed based on a concat...
