Pronunciation variation modeling for Mandarin with accent

چکیده
In order to solve the problem of the performance decrease when state-of-art automatic speech recognition (ASR) system facing accent speech, we propose the Pronunciation Variation Model (PVM). Two approaches are proposed to construct the PVM in this paper. 6.38% and 7.78% relative error rate reduction is achieved for Shanghai and Wuhan accent mandarin, respectively. The experiment on these two typical accent mandarin shows it is a possible way to deal with accent speech.

Accent-specific Mandarin adaptation based on pronunciation modeling technology
An accent adaptation approach using pronunciation variation modeling technology for Mandarin accent was proposed in this paper. As Chinese language is monosyllabic, the syllable pronunciation variation dictionary (SPVD) was built to depict the characteristics of accent. Firstly, the pronunciation modeling technology was utilized to get the context-independent and contextdependent accent-specifi...
متن کاملAccent modeling based on pronunciation dictionary adaptation for large vocabulary Mandarin speech recognition
A method of accent modeling through Pronunciation Dictionary Adaptation (PDA) is presented. We derive the pronunciation variation between canonical speaker groups and accent groups and add an encoding of the differences to a canonical dictionary to create a new, adapted dictionary that reflects the accent characteristics. The pronunciation variation information is then integrated with acoustic ...

This paper investigates foreign accent by comparing vowel production of native speakers, heritage and non-native learners with data from a large corpus of spontaneous Chinese learner speech. Snippets were evaluated by untrained Mandarin raters on accent ratings and followed up with acoustic analysis of vowel qualities. The rating result showed a high correlation between accent and pronunciation...

This paper studies pronunciation scoring algorithm in CALL system aiming at teaching native Chinese learn standard Mandarin. Most of the pronunciation scoring algorithms focus on non-native environment, which may not be suitable for native speakers. We bring up a new algorithm based on traditional posterior log-likelihood algorithm by weighting the initial part of Mandarin syllables, where fina...

This paper first provides an overview of factors that constrain ultimate attainment in adult second language (L2) pronunciation, finding that first language influence and the quantity and quality of L2 phonetic input account for much of the variation in the degree of foreign accent found across adult L2 learners. The author then evaluates current approaches to computer assisted pronunciation tr...
