Abstract

This paper investigates the hybridization of Genetic Algorithms (GA) with Recurrent Self-Organizing Maps (RSOM) for speech recognition. It ensures the benchmarking of its performance against traditional and deep learning-based methods, including Hidden Markov Models (HMM), Support Vector Machines (SVM), Convolutional Neural Networks (CNN), Recurrent Neural Networks (RNN), Long Short-Term Memory networks (LSTM), Gated Recurrent Units (GRU), and wave to vector 2.0 (wav2vec 2.0). The aim of this study is to demonstrate the performance of the hybrid GA-RSOM model implemented on an embedded system, such as a modern Digital Signal Processing (DSP). The evaluation is carried out in terms of reaction time and recognition accuracy for speech with very high variability and multilingual content. Experiments show that while the GARSOM model is slower than some models like CNN, it achieves a stable and precise recognition rate of up to 98 %, depending on the phonemes.

期刊介绍： The impact of computers has nowhere been more revolutionary than in electrical engineering. The design, analysis, and operation of electrical and electronic systems are now dominated by computers, a transformation that has been motivated by the natural ease of interface between computers and electrical systems, and the promise of spectacular improvements in speed and efficiency. Published since 1973, Computers & Electrical Engineering provides rapid publication of topical research into the integration of computer technology and computational techniques with electrical and electronic systems. The journal publishes papers featuring novel implementations of computers and computational techniques in areas like signal and image processing, high-performance computing, parallel processing, and communications. Special attention will be paid to papers describing innovative architectures, algorithms, and software tools.
