Vowel Pronunciation Accuracy Checking System Based on Phoneme Segmentation and Formants Extraction
نویسندگان
چکیده
In this paper, we developed a vowel sound accuracy checking system for educational purpose in learning foreign language. We employed an HMM (Hidden Markov Model) based phoneme segmentation algorithm, and used the 1st and 2nd formants as a measure of the vowel sound quality. We tested this system for several speakers and concluded that it produces reliable results for educational purpose.

Acoustic Analysis of Persian EFL Learners' Pronunciation of English Vowels
This paper reports the results of an experimental study on non-native production of English vowels. Two groups of Persian EFL learners varying in language proficiency were tested on their ability to produce the nine plain vowels of American English. Vowel production accuracy was assessed by means of acoustic measurements. Ladefoged and Maddison’s (1996) F1 F2 measurements for American English v...
متن کاملAn acoustic-phonetic feature-based system for automatic phoneme recognition in continuous speech
An acoustic-phonetic featureand knowledge-based system for the automatic segmentation, broad categorization and fine phoneme recognition of continuous speech is described. The system uses an auditory-based front-end processing and incorporates new knowledge-based algorithms to automatically segments the speech into phoneme-like segments that are further categorized into 4 main categories: sonor...
متن کاملGrapheme Segmentation of Tamil Speech Signals using Excitation Information with MFCC and LPCC Features
The major components of automatic Speech Recognition(ASR)are the pronunciation dictionary, language models, acoustic model and decoder. The Pronunciation dictionaries define the mapping between the words and basic sounds of a language and thus play a vital role in speech recognition systems. Construction of the pronunciation dictionary is expensive and time consuming since it requires the knowl...
متن کاملAutomatic Phoneme Segmentation with Relaxed Textual Constraints
Speech synthesis by unit selection requires the segmentation of a large single speaker high quality recording. Automatic speech recognition techniques, e.g. Hidden Markov Models (HMM), can be optimised for maximum segmentation accuracy. This paper presents the results of tuning such a phoneme segmentation system. Firstly, using no text transcription, the design of an HMM phoneme recogniser is o...
متن کاملBiologically Inspired Features Used For Robust Phoneme Recognition
Formants are regarded as the basic building blocks of vowels; however, they are very rarely used as features for difficult automatic speech recognition tasks. Formant based research is generally focused on formant extraction, because of the assumption that a better formant extraction method is the only manner to increase the effectiveness of formants. We challenge this assumption by investigati...
