Sasang Constitution, one branch of oriental medicine, claims that people can be classified into four different 'constitutions:' Taeyang, Taeum, Soyang, and Soeum. This study investigates whether the classification of the constitutions could be accurately made solely based on people's voice by analyzing the data from 46 different voices whose constitutions were already determined. Seven source-related parameters and four filter-related parameters were phonetically analyzed and the GMM(Gaussian mixture model) was tried on the data. Both the results from phonetic analyses and GMM showed that all the parameters (except one) failed to distinguish the constitutions of the people successfully. And even the single exception, B2 (the bandwidth of the second formant) did not provide us with sufficient reasons to be the source of distinction. This result seems to suggest one of the two conclusions: either the Sasang Constitutions cannot be substantiated with phonetic characteristics of peoples' voices with reliable accuracy, or we need to find yet some other parameters which haven't been conventionally proposed.

After establishing the rules for the phonetic transcription in French, quantitative analysis on the given text, Waiting for Godot, is performed. Analyzing the text by investigating the influence of phoneme distribution is very interesting in the phonostylistic point of view. Since the phonetic transcription rules are useful for its automation, the rules are carefully established in this paper. From the results of the phonetic transcription, we can investigate the distribution of individual phonemes and the different phoneme groups between dialogues and scenery indications for various characters.

Although Standard Korean is based on Seoul Korean, the phonetic realization of syllable codas in Seoul Korean has not been satisfactorily investigated. This paper aims to study how Seoul speakers pronounce syllable codas in certain phonetic contexts and what pronunciation they prefer among variants. It is noted that the realization of a syllable coda is different word by word and generation by generation. It is also noted that the syllable coda of a word is realized differently depending on the following vowel. And we discussed how the Principles of Standard Korean Pronunciation should be revised in the future, based on the results of this study.

The purpose of this study is to provide deeper understanding of how it is possible for people to understand PC communication language they have never seen or heard before without any problem. In order to answer this question, we focused on the vowel variation through which new variants are created (for PC communication), and hypothesized that there is a phonetic constraint which requires the vowel of the variant to be phonetically similar (to the maximum) to the vowel of the original word. Through the corpus analysis of the dictionary of PC communication language, we show that our hypothesis is justified by the fact that most of the variants we collected from the dictionary, that is, 90% of them, conformed to the phonetic constraint we postulated.

The purpose of this study was to show the characteristics of phonetic contrasts of one-syllable words and speech intelligibility in hearing-impaired adults. Seven subjects with hearing-impaired participated in this experiment(2 males, 5 females). The test materials are 77 pairs of one-syllable words with phonetic contrasts. The results of this study were as follows: (1) The average score of intelligibility(scored accuracy) was the highest in contrasts of onset feature. (2) The scored percentages of error(except for combinations of contrasts) were the highest in articulatory manner contrasts of onset, tongue height contrasts of nucleus, and articulatory place contrasts of coda, respectively.

Sasang Constitution, one branch of oriental medicine, claims that people can be classified into four different 'constitutions:' Taeyang, Taeum, Soyang, and Soeum. This study investigates whether the classification of the 'constitutions' could be accurately made solely based on people's voice by analyzing the data from 46 different voices whose constitutions were already determined. Seven source-related parameters and four filter-related parameters were phonetically analyzed and the GMM(gaussian mixture model) was tried with the data. Both the results from phonetic analyses and GMM showed that all the parameters (except one)failed to distinguish the constitutions of the people successfully.

The aim of this paper is to research on the actual condition of Koreans' Spanish consonants pronunciation with an emphasis on describing the phonetic different of Korean speakers and Spanish speakers. 40 Spanish words were chosen for the speech sampling, and 10 Spanish majoring Korean students from Seoul or Kyunggi Province and 3 Spanish speakers form Castile, Spain participated in the interview. The most noticeable phonetic differences of Korean speakers' pronunciation comparing with Spanish speakers are abstracted as follows: 1) The voiced stops are pronounced voiceless or weak voiced. 2) The voiced stops are slightly aspirated. 3) The length of voiceless consonants is quite longer than the length of proceeding vowel. 4) Fricatives and affricates are somewhat fronter, and weaker in the degree of friction. 5) There is a strong tendency to geminate dental lateral /l/ such as 'pelo' and to vocalize palatal lateral /$\rightthreetimes$/ such as 'calle' 6) Unlike in Spanish speech flap $\mid$r$\mid$ and trill [r] are pronounced similarly in Korean speech.

This presentation aims to explore some possibility of non-segmental phonetics usually ignored in phonetics education. In pedagogical phonetics, especially ESL/EFL oriented phonetics speech sounds tend to be classified in two criteria 1) 'pronunciation' which deals with segments and 2) 'prosody' or 'suprasegmentals', a criterion that deals with non-segmental elements such as stress and intonation. However, speech involves more dynamic processing. It is non-linear and multi-dimensional in spite of the linear sequence of symbols in phonetic/phonological transcriptions. No word is without pitch or voice quality apart from segmental characteristics whether it is spoken in isolation or cut out from continuous speech. This simply tells the dichotomy of pronunciation and prosody is merely a useful convention. There exists some room to consider dynamic non-segmental phonetics. Examples of non-segmental phonetic investigation, some of the analyses conducted within the frame of Firthian Prosodic Analysis, especially of the relation between vowel variants and foot types, are examined and we see what kind of auditory phonetic training is required to understand impressionistic transcriptions which lie behind the non-segmental phonetics.

The purpose of this paper is to design Speech Database for Korean pronunciation education. For this purpose, I investigated types of speech errors of Korean-learners, made texts for recording, which involves all types of speech errors, and showed how to gather speech data and how to tag their informations. It's natural that speech data should include Korean-learners' speech and Korean people's speech, because Speech DB that I try to develop is for teaching Korean pronunciation to foreigners. So this DB should have informations about speakers and phonetic informations, which are about phonetic value of segments and intonation of sentences. The intonation of sentence varies with the type of sentence, the structure of prosodic units, the length of a prosodic unit and so on. For this reason, Speech DB must involve tags about these informations.

Research in the Center for Pediatric Auditory and Speech Sciences (CPASS) is attempting to characterize or phenotype children with speech delays based on acoustic-phonetic evidence and relate those phenotypes to chromosome loci believed to be related to language and speech. To achieve this goal we have adopted a highly interdisciplinary approach that merges fields as diverse as automatic speech recognition, human genetics, neuroscience, epidemiology, and speech-language pathology. In this presentation I will trace the background of this project, and the rationale for our approach. Analyses based on a large amount of speech recorded from 18 children with speech delays will be presented to illustrate the approach we will be taking to characterize the acoustic phonetic properties of disordered speech in young children. The ultimate goal of our work is to develop non-invasive and objective measures of speech development that can be used to better identify which children with apparent speech delays are most in need of, or would receive the most benefit from the delivery of therapeutic services.
