Teaching Thai Language Literacy: Proposed of Using Speech Recognition Technology Techniques to Detect Read Aloud in Thai Tonal Conjugation for Primary Education Students

Abstract

This academic article has objectives were 1) to study the techniques in data analyzing of speech recognition systems techniques to detect reading aloud skills in Thai tonal conjugation for Primary Education Students, and 2) to study the effect of speech recognition systems techniques to detect reading aloud skills in Thai tonal conjugation for Primary Education Students. Sample group in this research were 30 Primary Education Students in Grades 4 – 6 of Wat Na Klang School in Nakhon Sawan Province, Thailand. Research tools was speech recognition systems techniques to detect reading aloud skills in Thai tonal conjugation.Results showed that,1) the three techniques involved in sound analysis consisted of Spectrogram Sound Wave Change Techniques, Wavelet Transform Audio Format Conversion Techniques, and two sets of data similarity comparison techniques named Dynamic Time Warping (DTW). The researchers used three techniques in analysis and comparison for making the more similar to the sound signal than using a single technique to analyze. 2) the effect of using speech recognition system to detect reading aloud skills in Thai tonal conjugation showed results of pronunciation practice and compared the similarity of audio signals that after using the technique in 5 analytical times, the largest average result was 93.52 Percent, the least average result was 87.75 Percent, and the total average result was 90.66 Percent.
