ICONIP (2) - Consonantal recognition using SVM and a hierarchical decision structure based in the Articulatory Phonetics
Neural Information Processing, 2012Co-Authors: A. De Andrade Bresolin, Hermes Irineu Del MonegoAbstract:A new concept of making the Consonantal Recognition is proposed in this work, where used units (phonemes and syllables) to make the word recognition. This concept was carried out by a hierarchical decision structure, based on the Articulatory Phonetics and SVM. The speech features used were MFCC and WPT. Eighteen consonantal phonemes have been used in the recognition. The database used for the recognition was a set of two-syllable words of the Brazilian Portuguese language. The experimental results showed success rates of 98.41% for the user-dependent case. Our focus was the dependent speaker in order to validate the new proposal.

Target-filtering model based Articulatory movement prediction for Articulatory control of HMM-based speech synthesis
2012 IEEE 11th International Conference on Signal Processing, 2012Co-Authors: Zhen-hua LingAbstract:This paper presents a target-filtering model to predict the movements of articulators for Articulatory control of hidden Markov model (HMM) based speech synthesis. This model is a bidirectional filtering process on the time-aligned articulation target sequence. The bidirectional filtering could achieve both anticipatory coarticulation and regressive coarticulation. As all the parameters of the model have definite physical meaning, we can control the generation of the Articulatory features flexibly with the guidance of Articulatory Phonetics. And the Articulatory features produced by the target-filtering model can be adopted for a multiple regression HMM (MRHMM)-based parametric speech synthesis system. So we can control the pronunciation of vowels by Articulatory features instead of the set of context features. Experimental results show that we can control the pronunciation among /Θ/, /e/, /ae/ effectively just by modifying the articulation targets.

ISM - Consonantal Recognition Using SVM and New Hierarchical Decision Structure Based in the Articulatory Phonetics
2008 Tenth IEEE International Symposium on Multimedia, 2008Co-Authors: A. De Andrade Bresolin, Adrião Duarte Dória Neto, Pablo Javier AlsinaAbstract:In this work, a new concept of making the consonantal recognition is proposed. We used several units (phonemes, diphones and syllables) to make the word recognition. This concept was carried out by a new hierarchical decision structure, based on the Articulatory Phonetics and SVM (support vector machine). The speech features used were MFCC (mel-frequency cepstral coefficient) and WPT (waveletpacket transform). Eighteen consonantal phonemes have been used in the recognition. The database used for the recognition was a set of two-syllable words of the Brazilian Portuguese language. The experimental results showed success rates of 98.41% for the user dependent case.

Articulatory Phonetics in the first year spanish classroom
The Modern Language Journal, 2000Co-Authors: Deborah ArteagaAbstract:focus of this article is twofold: I reconsider the general question of the role of Articulatory Phonetics in the second language (L2) classroom and review the Phonetics presentation in 10 recent first-year Spanish texts. Pronunciation has been accorded little importance within recent methodological approaches, although their stated goals of communication and intelligibility in fact require the incorporation of explicit Phonetics instruction in the language classroom. Considering the first-year Spanish L2 classroom, I propose a Phonetics program based on the notion of a learner's dialect (cf. Bergen, 1974). I then measure the Phonetics presentation of 10 Spanish textbooks against a learner's dialect, and find that pronunciation sections are in most cases incomplete and inaccurate and provide for no self-monitoring or recycling. This article argues against the current trend reflected in these texts, which relegates pronunciation to the laboratory manual or eliminates it altogether.

Articulatory Phonetics of coronal stops in monolingual and simultaneous bilingual speakers of canadian french and english
Journal of the Acoustical Society of America, 2013Co-Authors: François-xavier Brajot, Fatemeh Mollaei, Megan Callahan, Denise Klein, Shari R. Baum, Vincent L. GraccoAbstract:Previous studies of bilingual speech production have relied on individuals whose age of acquisition of their second language varies. In the proposed research, we take advantage of the unique multilingual environment of Montreal and examine speech production in individuals who have acquired two languages from birth and compare the results to monolingual speakers. Electromagnetic recordings of single-word productions were carried out on three groups of female Canadian speakers (French monolingual, English monolingual, French-English simultaneous bilingual). Spectral moment and formant transition analyses of coronal burst segments showed cross-linguistic differences across vowel contexts. Tongue place of articulation and shape likewise indicated cross-linguistic differences in static Articulatory positions. Kinematic analyses further identified language-specific movement patterns that helped clarify certain results from the acoustic analyses, namely that spatiotemporal characteristics of coronal articulation help enhance vocalic dimensions important to the respective language. Similar patterns were observed among the bilingual subjects, with the notable exception that acoustic and kinematic spaces narrowed considerably, resulting in reduced overlap between languages. It appears that simultaneous bilingual speakers not only follow language-appropriate Articulatory and acoustic patterns, but further minimize areas of cross-linguistic convergence otherwise found among monolingual speakers.
