DaNangVMD: Vietnamese Speech Mispronunciation Detection

  • Ket Doan Nguyen

Abstract

Automatic Speech Recognition, also known as ASR, has grown
exponentially over the past decade and is used to recognize and translate human
speech into readable text automatically. However, Vietnamese Speech
Recognition faces critical challenges such as easy to make mispronunciations as
well as a huge variant in Vietnamese speech. In this work, we dive into the
difficult challenge of Mispronunciation Detection (MD) in the Vietnamese
language. As such a tonal language, Vietnamese is not only based on consonants
and vowels but also on variations in pitch or tone during pronunciation. In this
paper, we propose DaNangVMD model for detecting mispronunciations in
Vietnamese speech based on the audio speech and canonical transcript. By
leveraging multi-head attention-based multimodal representation from the
embeddings of the phonetic encoder and linguistic encoder, DaNangVMD aims
to provide a robust solution for accurate mispronunciation detection and
diagnosis. Throughout the extensive evaluation, the proposed DaNangVMD
exhibits superior performances rather than that of the PAPL baseline models by
15% in F1 score and 13 % in accuracy.
