The purpose of this study is to investigate the difference of vowel duration due to the voicing of word-final consonants in English and its relation to the types of word-final consonants (stops vs. fricatives), (partial) devoicing, and stop releasing. Addtionally, this study attempts to interpret the findings from the functional view that the vowels before voiced consonants are produced with a longer duration in order to enhance the salience of the voicing of word-final consonants. This study conducted a recording experiment with English native speakers, and measured the vowel duration, the degree of (partial) devoicing of word-final voiced consonants and the release of word-final stops. First, the results showed that the ratio of the duration difference was not influenced by the types of word-final consonants. Second, it was revealed that the higher the degree of (partial) devoicing of word-final voiced consonants, the longer vowel duration before word-final voiced consonants, which was compatible with the prediction based on the functional view. Lastly, the ratio of the duration difference was greater when the word-final stops were uttered with the release compared to when uttered without the release, which was not consistent with the functional view. These results suggest that it is not sufficient enough to explain the voicing effect by its function of distinguishing the voicing of word-final consonants.

The English word-final /rl/ cluster poses a particular problem for Korean learners of English because it is the sequence of two sounds, /r/ and /l/, which are not contrastive in Korean. This study compared the similarity distances between English and Korean speakers’ /rl/ productions using the dynamic time warping (DTW) algorithm. The words with /rl/ ( pearl , world ) and without /rl/ ( bird , word ) were recorded by four English speakers and four Korean speakers, and compared pairwise. The F2-F1 trajectories, the acoustic correlate of velarized /l/, and F3 trajectories, the acoustic correlate of /r/, were examined. Formant analysis showed that English speakers lowered F2-F1 values toward the end of a word, unlike Korean speakers, suggesting the absence of /l/ in Korean speakers. In contrast, there was no significant difference in F3 values. Mixed-effects regression analyses of the DTW distances revealed that Korean speakers produced /r/ similarly to English speakers but failed to produce the velarized /l/ in /rl/ clusters.
英语单词的词尾/rl/集群给韩国英语学习者带来了一个特别的问题，因为它是两个音的顺序，/r/和/l/，这两个音在韩语中不是对比音。本研究使用动态时间扭曲(DTW)算法比较了英语和韩语使用者的/rl/产品之间的相似距离。有/rl/(珍珠，世界)和没有/rl/(鸟，单词)的单词分别由4名说英语的人和4名说韩语的人记录下来，并进行两两比较。研究了F2-F1轨迹(velized /l/的声学相关性)和F3轨迹(velized /r/的声学相关性)。Formant分析结果显示，英语使用者与韩语使用者不同，F2-F1值在单词末尾降低，这表明韩语使用者中没有/l/。相比之下，F3值无显著差异。DTW距离的混合效应回归分析显示，说韩语的人产生/r/的方式与说英语的人相似，但不能产生化的/l/ in /rl/集群。

Previous studies have provided important findings on children's speech production development. They have revealed that essentially all aspects of children's speech shift toward adult-like characteristics over time. Nevertheless, few studies have examined the perceptual aspects of children's speech tokens, as perceived by naive adult listeners. To fill the gap between children's production and adults' perception, we conducted cross-sectional perceptual studies of monosyllabic words produced by children aged two to six years. Monosyllabic words in the consonant-vowel-consonant form were extracted from children's speech samples and presented aurally to five listener groups (20 listeners in total). Generally, the agreement rate between children's production of target words and adult listeners' responses increases with age. The perceptual responses to tokens produced by two-year old children induced the largest discrepancies and the responses to words produced by six years olds agreed the most. Further analyses were conducted to identify the sources of disagreement, including the types of segments and syllable structure. This study makes an important contribution to our understanding of the development and perception of children's speech across age groups.

The purpose of this study was to investigate the temperament characteristics associated with stuttering subtypes (persistent and recovered) over time and the relationship between those characteristics and stuttering severity. This four-year longitudinal study covered 41 preschool children who stutter (CWS) and 30 preschool children who do not stutter (the CWNS group). At the final visit, 27 CWS were classified as the Recovered group and 14 CWS were classified as the Persistent group. Using the Children’s Behavior Questionnaire-Short Form, each participant’s temperament characteristics were measured twice: at one year and two years after the initial visit. The three subscale scores (Extraversion, Negative Affectivity, and Effortful Control) and the 15 component scores were analyzed, and they were used for between-group and between-visit comparisons. The Persistent group showed a significantly higher Negative Affectivity subscale score at every visit than the Recovered and CWNS groups. Within this subscale, significant group differences were found in the ‘Fear’ and ‘Anger/Frustration’ components, demonstrating that the Persistent group scored higher than the Recovered and CWNS groups. There was no significant correlation between the subscale and component scores and the stuttering severity scores within the Persistent group at any visit. These results support the proposition that these two stuttering subtypes have different temperament characteristics; they also imply that temperament might be influenced by stuttering experience over time.

This study compared the voice range profiles (VRPs) with glissando and simplified VRP methods with 57 men who were in premutation (8 – 13 years), mutation (11 – 16 years), and postmutation (10 – 24 years) stages. The difference between modal and falsetto areas measured in two VRP methods was also compared. As the results, the average fundamental frequency (F0) was in the order of premuaton>mutation>postmutation. The maximum F0 (F0max), the range of F0 (F0range), the maximum intensity (Imax), and the range of intensity (Irange) were the lowest in the mutation stage, and these variables were higher in falsetto area than in modal area in both methods. In addition, most variables of VRP in glissando were higher than in simplified VRP, but the differences were not significant. This study showed that, in men in mutation stage, due to the temporary anatomical and physiological changes of the larynx, the mechanism of the vocal folds vibration changes and VRP shows a different pattern from that of other age groups. Both the VRPs of glissando and simplifed VRP are suitable for clinical practice by experienced examiners. And it is necessary to measure not only the falsetto area but also the modal area when measuring VRP.

This study aims to enhance English pronunciation education for Korean students by examining the impact of standard Korean and Gyeongsang regional dialect on the articulation of English vowels. Data were obtained through the Korean-Spoken English Corpus (K-SEC). Seven Korean words and ten English mono-syllabic words were uttered by adult, male speakers of standard Korean and Gyeongsang regional dialect, in particular, speakers with little to no experience living abroad were selected. Formant frequencies of the recorded corpus data were measured using spectrograms, provided by the speech analysis program, Praat. The recorded data were analyzed using the articulatory graph for formants. The results show that in comparison with speakers using standard Korean, those using the Gyeongsang regional dialect articulated both Korean and English vowels in the back. Moreover, the contrast between standard Korean and Gyeongsang regional dialect in the pronunciation of Korean vowels (/ 으 /, / 어 /) affected how the corresponding English vowels (/ə/, /ʊ/) were articulated. Regardless of the use of regional dialect, a general feature of vowel pronunciation among Korean people is that they show more narrow articulatory movements, compared with that of native English speakers. Korean people generally experience difficulties with discriminating tense and lax vowels, whereas native English speakers have clear distinctions in vowel articulation.

This study examines the effectiveness of semi-occluded vocal tract exercise (SOVTE) conducted through telepractice for 10 female teachers who have experienced vocal discomfort while working in early childhood education facilities (childcare centers, kindergartens). The effects of SOVTE conducted through telepractice were evaluated based on the Korean voice handicap index (KVHI), the Korean version of the voice activity and participation profile (K-VAPP), vocal effort, and auditory perception evaluation by using the grade, roughness, breathiness, asthenia, and strain (GRBAS) scale. The results show that total, functional, and physical scores of KVHI significantly reduced after SOVTE. The total score in K-VAPP significantly reduced after SOVTE. Moreover, vocal effort significantly decreased after SOVTE. However, statistically significant differences were not noted in GRB scales before and after SOVTE. In conclusion, early childhood teachers experienced reduced vocal discomfort SOVTE conducted through telepractice. The study results indicate that voice therapy conducted through telepractice is an effective method for reducing vocal discomfort in early childhood teachers.

In this study, we examined the interactive aspects between pitch reduction phenomena considered a universal language phenomenon and native language interference in the production of L2 intonation performed by Chinese learners of Korean. To investigate their interaction, we conducted an acoustic analysis using acoustic measures such as pitch span, pitch level, pitch dynamic quotient, skewness, and kurtosis. In addition, the correlation between text comprehension and pitch was examined. The analyzed material consisted of four Korean discourses containing five and seven sentences of varying difficulty. Seven Korean native speakers and thirty Chinese learners who differed in their Korean proficiency participated in the production test. The results, for differences by language, showed that Chinese had a more expanded pitch span, and a higher pitch level than Korean. The analysis between groups showed that at the beginner and intermediate levels, pitch reduction was prominent, i.e., their Korean was characterized by a compressed pitch span, low pitch level, and less sentence internal pitch variation. Contrariwise, the pitch use of advanced speakers was most similar to Korean native speakers. There was no significant correlation between text difficulty and pitch use. Through this study, we observed that pitch reduction was more pronounced than native language interference in the phonetic layer.

This study investigated whether Korean learners improve acoustic cue weights to identify Korean lenis and aspirated stops in the direction of native values through perception training that focused on contrasting the stops in various phonetic contexts. Nineteen native Chinese learners of Korean and two native Korean instructors for the perception training participated in the experiment. A training group and a non-training group were divided according to pretest results, and only the training group participated in the training for 5 days. To estimate the perceptual weights of the stop cues, a pretest and a posttest were conducted with stimuli whose stop cues (F0 and VOT) were systematically manipulated. Binary logistic regression analyses were performed on each learner's test results to calculate perceptual β coefficients, which estimate the perceptual weights of the acoustic cues used in identifying the stop contrast. The training group showed a statistically significant increase of 0.451 on average in the posttest for the coefficient values of the F0, which is the primary cue for the stop contrast, whereas the non-training group showed an insignificant increase of 0.246. The patterns of change in the F0 use after training varied considerably among individual learners.

The training group showed a statistically significant increase of 0.451 on average in the posttest for the coefficient values of the F0, which is the primary cue for the stop contrast, whereas the non-training group showed an insignificant increase of 0.246. The patterns of change in the F0 use after training varied considerably among individual learners.","PeriodicalId":255285,"journal":{"name":"Phonetics and Speech Sciences","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114308633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
