In order to better teach pronunciation to students, it is necessary to gain a better appreciation of the types of pronunciation patterns and issues that Japanese speakers encounter when attempting to speak in English. To highlight some of these issues, a sample dialogue between two Japanese learners was recorded and analyzed for segmental and suprasegmental features. The analysis revealed that ...

Many beginning-level Chinese learners, particularly those whose mother tongue is not a tone language find it challenging to learn Chinese pronunciations and tones. Yet pronunciation practice in formal language class settings is limited. Therefore, it has become necessary to develop computer-assisted and adaptive training systems to help learners practice Chinese pronunciation outside of class. ...

In this paper, we investigated the parameters for determining the degree of pronunciation improvement by using the formant comparison method. Many speech parameters have been studied to identify inaccurate pronunciation features. Generally, the method of grasping the inaccurate pronunciation is analyzed by using the change of pitch and formant. Formants have various information such as the indi...

Pronunciation modeling for large vocabulary speech recognition attempts to improve recognition accuracy by identifying and modeling pronunciations that are not in the ASR systems pronunciation lexicon. Pronunciation variability in spontaneous Mandarin is studied using the newly created CASS corpus of phonetically annotated spontaneous speech. Pronunciation modeling techniques developed for Engl...

The paper aims at exploring the relationship between perceived pronunciation performance and metalinguistic awareness in the acquisition of third language phonology. The study involved 27 participants with Polish as L1, English as L2 and French as L3. In the first part of the study, third language pronunciation performance was assessed by means of online ratings involving 3 components: foreign ...

In this paper, we describe a cross-morpheme pronunciation variation model which is especially useful for constructing morpheme-based pronunciation lexicon for Korean LVCSR. There are a lot of pronunciation variations occurring at morpheme boundaries in continuous speech. Since phonemic context together with morphological category and morpheme boundary information affect Korean pronunciation var...

This report describes the process of creating a pronunciation dictionary and phonological lexicon for Hungarian for the purpose of aiding in linguistic research on Hungarian phonology and phonotactics. The pronunciation dictionary was created by transforming orthographic forms to pronunciation representations by taking advantage of systematic deviations between Hungarian orthography and pronunc...

This study demonstrates how knowledge of language transfer can enable a computer-assisted pronunciation teaching (CAPT) system to effectively detect and diagnose salient mispronunciations in second language learners’ speech. Our approach uses a HMM-based speech recognizer with an extended pronunciation lexicon that includes both a model pronunciation for each word and common pronunciation varia...
