A Novel Method for Recognizing Vietnamese Voice Commands on Smartphones with Support Vector Machine and Convolutional Neural Networks

الملخص EN

This paper will present a new method of identifying Vietnamese voice commands using Google speech recognition (GSR) service results.

The problem is that the percentage of correct identifications of Vietnamese voice commands in the Google system is not high.

We propose a supervised machine-learning approach to address cases in which Google incorrectly identifies voice commands.

First, we build a voice command dataset that includes hypotheses of GSR for each corresponding voice command.

Next, we propose a correction system using support vector machine (SVM) and convolutional neural network (CNN) models.

The results show that the correction system reduces errors in recognizing Vietnamese voice commands from 35.06% to 7.08% using the SVM model and 5.15% using the CNN model.
