Systems based on automatic speech recognition (ASR) technology can provide important functionality in computer assisted language learning applications. This is a young but growing area of research motivated by the large number of students studying foreign languages. Here we propose a Hidden Markov Model (HMM)-based method to detect mispronunciations. Exploiting the specific dialog scripting employed in language learning software, HMMs are trained for different pronunciations. New adaptive…

Mispronunciation detection for language learning and speech recognition adaptation

In this thesis, a new HMM-based text-dependent mispronunciation system is introduced using text Adaptive Frequency Cepstral Coefficients (AFCCs) and it is shown that this system outperforms the conventional HMM method based on Mel Frequency Ceps (MFCCs).

A Two-Pass Framework of Mispronunciation Detection and Diagnosis for Computer-Aided Pronunciation Training

This paper presents a two-pass framework with discriminative acoustic modeling for mispronunciation detection and diagnoses (MD&D), which guarantees full coverage of all possible error patterns while maximally exploiting the phonetic information derived from the text prompt.

XDF-REPA: A Densely Labeled Dataset toward Refined Pronunciation Assessment for English Learning

This paper addresses the issue of refined pronunciation assessment (RPA), which aims at providing more refined information to L2 learners, and presents the XDF-REPA dataset, which is freely available to the public.

MFCC-Based Voice Recognition System for Home Automation Using Dynamic Programming

Speech recognition is a multileveled pattern recognition task, in which acoustical signals are examined and structured into a hierarchy of subword units, words, phrases, and sentences, which can best be exploited by combining decisions probabilistically at all lower levels, and making discrete decisions only at the highest level.



The SRI EduSpeak System: Recognition and Pronunciation Scoring for Language Learning

This work reports results on the application of adaptation techniques to recognize both native and nonnative speech in a speaker-independent manner and discusses the pronunciation scoring paradigm and shows experimental results in the form of correlations between the pronunciation quality estimators included in the toolkit and grades given by human listeners.

Automatic mispronunciation detection for Mandarin

Proposing scaled log-posterior probability (SLPP) and weighted phone SLPP to get the better measure of pronunciation quality and introducing speaker normalization of speaker adaptive training (SAT) and speaker adaptation of selective maximum likelihood linear regression (SMLLR) to get a better statistical model are presented.

Implementation of an extended recognition network for mispronunciation detection and diagnosis in computer-assisted pronunciation training

A set of context-sensitive phonological rules based on cross-language (Cantonese versus English) analysis which has also been validated against common mispronunciations observed from the learners interlanguage are developed.

Automatic evaluation and training in English pronunciation

A study of the feasibility of automati cally grading the performance of Japanese students when reading English aloud showed that ratings of speech quality by experts are very reliable and automatic grades correlate well with those expert ratings.

Automatic derivation of phonological rules for mispronunciation detection in a computer-assisted pronunciation training system

An approach for automatic derivation of phonological rules from L2 speech that captures the canonical pronunciations of words, as well as the possible mispronunciations, and offers improved performance in diagnostic accuracy.
