This article claims that English liquid consonants are characterized by the presence of complex place nodes, regardless of dialectal varieties. The primary difference between rhotic and laterals can be pursued in a phonological sense. The level of subbranching nodes is in charge of the disparities among two types of liquids: the branching immediately below the Coronal node with laterals, while branching at the secondary sublevel with rhotics. In this context, the processes of rhotic deletion and lateral vocalization can be understood as those motivated to get rid of complex place nodes. That is, those processes take place as part of phonological attrition. Next, the onset/coda asymmetry regarding liquids stems from the dispreference of vocoid at the onset position, which is readily accounted for by the series of constraints on the well-formedness on the onset, namely Harmonic Onset. The rationale of gradualness and harmonic improvement proposed by Harmonic Serialism is useful to separate the attested outputs from unattested ones across the whole gamut of English varieties. All in all, the primary benefits of our analysis can be found in the consistence in the explanation for the operations running through the sounds regarded as belonging to liquid consonants, comprising the whole range of rhotic and lateral consonants.

This study was conducted to clarify the characteristics of vocalization of laying hen related with space in battery cage. The size of cages were classified into control (0.30 m ${\times}$ 0.14 m ${\times}$ 0.55 m, length ${\times}$ width ${\times}$ height), small (0.21 m ${\times}$ 0.14 m ${\times}$ 0.55 m) and large (0.30 m ${\times}$ 0.30 m ${\times}$ 0.55 m) size. Vocalization of 16 individuals of laying hen in each group of Hy-Line Brown (80 week old) were recorded 3 hours per day (10:00am~11:00am, 3:00pm~4:00pm and 7:00pm~8:00pm) using digital recorder and microphone during October 2008 and February 2009. Characteristics of frequency, intensity and duration of vocalization were analyzed by GLM (general linear model) and Duncan's multi-test. There were differences in basic and maximum frequency, and intensity based on analysis of spectrogram and spectrum among different cage sizes. Vocalization of laying hen would be one of the indicators to understand the stress caused by rearing space in batter cage.

Avian vocalization has been main topics in studying animal communication. The structure and usage as well as development and function of vocalization vary enormously among species and even among populations, and thus we reviewed the general patterns of song learning and the consequences of song communication in birds at the behavioural level: first, we compared the different learning phenomena between non-songbird and songbird, and we investigated the learning process of songbird both in the field and in the lab, which are needed to fully understand vocal communication. Second, we discussed a recent trend of sexual selection hypothesis explaining the structural and functional diversity of song in songbirds with repertoire and presented how the repertoire is actually used between neighbours based on individual recognition.

Pop singers frequently use breathy voice to express diverse emotion. Such method is the major factor that divides vocalization in pop and classical music. Using breathy voice too much for a long time could make singer short-winded, which might cause the voice injured. In order to prevent the problem, singers need to find resonance balance between high notes and low notes and among vowels. Moreover, they should take more attention when producing resonance in consonants with much air flow. Along with finding resonance balance, if skilled at controlling the volume of voice, singers can use the breathy voice selectively at the desired part, adjusting close quotient freely. Through this kind of approach, pop singers can develope their unique style of vocalization and avoid the vocal damage.

The purpose of this study is to investigate the features of Korean infants' vocalizations according to the stages models. A total 88 infants, whose ages range from 1 to 18 months, participated in this study. This age is a critical period for vocal development. However, the study of infants' vocalizations has typically focused on children over the age of two. Because of restrictions related to the study of younger infants, from birth to the age of two, it is usually difficult to investigate what are the major features of their vocal development. Therefore, this study provides documentation and analysis of the features of infant vocalization and their vocal development stages. The results shows that the stages model of Oller & Lynch (1992) might be adapted for Korean infants' vocal development. Furthermore, the features of the infants' vocalization are not linearly appeared one stage to the next stage, but are overlapped (Koopmans-van Beinum & van der Stelt, 1986; Nathani et al., 2006; Oller, 1980; Stark, 1980; Vihman, 1996).

In this paper, I proposed a sound model generation and a most frequent model search algorithm for recognizing animal vocalization. The sound model generation algorithm generates a optimal set of models through repeating processes such as the training process, the Viterbi Search process, and the most frequent model search process while adjusting HMM(Hidden Markov Model) structure to improve global recognition rate. The most frequent model search algorithm searches the list of models produced by Viterbi Search Algorithm for the most frequent model and makes it be the final decision of recognition process. It is implemented using MFCC(Mel Frequency Cepstral Coefficient) for the sound feature, HMM for the model, and C# programming language. To evaluate the algorithm, a set of animal sounds for 27 species were prepared and the experiment showed that the sound model generation algorithm generates 27 HMM models with 97.29 percent of recognition rate.

The in-country interest in vocalists is worthy of notice. However, the public, including experts, don't have sufficient information for their interest. In this situation, the popularity of Seth Riggs' books is surprising, because his major is vocal music, not popular music, although he is known as 'a great vocal trainer'. Therefore, we should analyze his vocalization methods and compare them with Bel Canto. His skills are (focused on) SLS (Speech-level singing). The unique styles he used are related to Bel Canto in vocal music, but with some differences. Nevertheless, both styles have something in common. For example, they are similar in that they continue to keep up with the times, so as to improve and evolve. Therefore, it is important for the selected passages to be investigated and presented, based on the individual body conditions and properties. Seth Riggs' vocalization method should be systematically examined too. This is because it has great influence on the public.

The purpose of this study was to use high-speed digital imaging (HSDI) to compare vocal vibratory behaviors of persons who stutter (PWS) and persons with muscle tension dysphonia (PMTD) for uttering the /i/ vowel in a bid to identify the characteristics of vocal fold vibratory behaviors of PWS. This study surveyed seven developmental PWSs and seven PMTDs. The findings of the study indicated the following: first, regarding the two groups' vocal fold vibratory behaviors, of seven PWSs, three were found to be close vocal tract (VC) and four were found to be combination vocal tract (VCB). Of the seven PMTDs, one was found to be VC, and the other six were found to be VCB. These results indicate that a voiceprint which is different from the open vocal tract (VO) found in normal groups in research conducted by Jung, et al. (2008b) appeared in both groups of this study. Even between the two groups, there is a difference in the voiceprint before vocalization. Second, a VKG analysis was conducted to identify the two groups' vocal cord contact quotient. As a result, the PWS group's vocal cord contact quotient changed gradually from an irregular one at the initial vocalization stage to a regular one. The PMTD group continued the tension at the initial vocalization. Putting together all of these results, there is a difference in vocal fold vibratory behaviors between PWSs and PMTDs when they speak. Thus, there was a difference in muscular tension between the two groups.

The purpose of this study was to examine the relationship among infants' nonverbal communication, maternal verbal behaviors and the infants' acquisition of vocabulary. The subjects were 93 pairs of 10 to 18 months old infants and their mothers residing in the Seoul and GyeongGi-Do area. The results were as follows : (1) In terms of the infants' nonverbal communicative means, it appeared that the group of 16~18 month olds utilized more gesture and vocalization. As regards the infants' nonverbal communicative functions in terms of social behavior and joint attention, the group of 16~18 month olds was found to perform more of the behaviors from this category than the other groups. There was a significant difference in the maternal verbal behavior among the different age groups. (2) Among the infants' nonverbal communicative means, gesture and vocalization, there appeared to be a significant relationship between vocalization and the infants' acquisition of vocabulary. In addition, there was an important relationship between the high usage of infants' nonverbal communicative functions with behavior regulation and the high usage of joint attention and the successful acquisition of vocabulary among infants. (3) Social play, which is a maternal verbal behavior categorized as one of the strategies for getting infants' attention, was significantly related to the acquisition of infants' vocabulary. (4) When mothers used more imitating sounds and mimetic words, requests for information, descriptions, conventional social expressions, and imitation to enhance responsiveness, infants were found to have acquired a larger vocabulary.

From the year 2000, an ironic phenomenon struck the Korean pop field with a number of male vocalists singing with similar voice tone colors and with almost the same vocal techniques. People called it "So-mo-ri", and this technique caught on with the public during that period of time. In the early 80s, plenty of vocalists tried to imitate Cho Yong-phil's singing method after his hit song 'Lady outside the window'. However, producing and releasing albums with the same singing method had never been done in history. In this study, I would like to analyse and conclude what the "So-mo-ri" technique was and how this technique began. I would further like to research the vocalization methods that were used.
