In this paper, we proposed a new customized e-Ring(Enterprise Ring Back Tone) system which could be represented each user and organization feature. The e-Ring system provided the ring back tone and additional services to reduce the waiting time when the client called an organization. This system was for an appropriate organization public relations instead of the meaningless ring back tone which was used usual call, also was maximized the service availability and work efficiency which was obtained from the automatic response and service suppling to users who had needs and questions.

Recent growth of ring-tone and ring-back-tone download market as the derived market of cellular phone yields the new trend in music consumption from listening to display. This means that consumer purchase the ring-tone and RBT not for his appreciation but for counterpart's consumption, in a word, conspicuous consumption. Study aims at questions on whether cellular phone user can perceive the ring-tone and RBT's brand personality and how they express their self-image via ring-tone and RBT. Survey was administered for 196 college students who is dominant purchase group of market segment. Hypotheses are such as : congruity of self image and brand personality of ring-tone and RBT. Through the T-test, findings said that user's extrovert self image are not led to ring-tone's extrovert brand personality and user's introvert self image are not led to introvert ring-tone's brand personality of ringtone. same result was applicable to RTB. Cellular phone user's purchase behavior are different from those of product and service.

Mobile phone is necessary articles by increasing mobile communication now. People usually use the Mobile phone in any time and place. Ring tone of Mobile phone effect owner or other person. The sound level of Mobile phone ring tone could be considered as noise if it is too loud a specific situation. Manufacturing company improve ring tone of mobile phone better in consumer's perception. In this study, we record ring tone of mobile phone and estimated the complexity and nonlinear characteristics of the relation between subjective evaluation and sound metrics. Linear regression models were obtained for the subjective evaluation and sound quality metrics. Semantic Differential Method is used to study sound quality Evaluation. To analyze the sound quality of ring tone.

As wireless internet market grows rapidly, demands of various contents in wireless internet is significantly being increased. The contents that customers are taking advantage of have changed from single media content to multimedia content. As the technology of cellular telephone and broadband grows, the development of multimedia contents that can future represent characteristic of user will be more increased. One example of such content developments is ring-tone content service. Ring tone content service changed from existing simple ring tone to various sound services that depend on characteristic of user. In this paper, we design and implement the multimedia greeting assistant system that firsthand produces multimedia greeting contents using various multimedia contents and provides multimedia greeting service to represent characteristic of user through elevating ring tone content service.

As wireless internet market grows rapidly, demands of various contents in wireless internet are significantly being increased. The mobile contents have been changed from single media contents such as text and voice to multimedia contents. As the technologies of cellular phone and broadband grow, the development of multimedia contents that can well represent the characteristics of users will be more increased. One example of such content developments is a ring-tone content service. Ring-tone content services have been changed from existing simple ring-tone to various sound services that depend on characteristic of user. In this paper, we design and implement a multimedia greeting system for the next generation mobile content service. Our system produces multimedia greeting contents using various multimedia contents and represents the characteristics of users through the elevation of ring-tone content services.

본 연구에서는 Ring-Back-Tone(RBT)의 개성이 통화 상대자의 퍼스널리티를 측정하는데 영향을 끼치는가에 대하여 실험연구를 진행하였다. 음악과 통화상대자의 퍼스널리티를 측정하기 위해, 성격 5요인 모형에서 음악의 특성과 밀접한 관련을 가진 3가지 요인인 Openness(개방성), Extroversion(외향성), Neuroticism(신경성)에 중심으로 각 요인에 속하는 12가지 하위 특성(trait)를 측정 도구로 활용하였다. 예비실험에서는, 17가지의 음악의 퍼스널리터를 측정하였으며 이 중 3가지를 선정하여 본 실험의 RBT로 설정하였다(N=15). 본 실험에서는 동일한 통화 상대자의 퍼스널리티에 대하여 각각의 RBT 음악의 경우마다 측정한 결과를 비교 분석하였으며, 3가지 RBT와 RBT를 설정하지 않은 대조군에 대하여 각각 15명의 피실험자들이 참여하였다(N=60). 피실험자들은 통화 상대자의 퍼스널리티의 Openness와 Extroversion을 측정하는데 있어 무의식중에 인지된 RBT의 개성의 영향을 받는 것으로 나타났다(p<0.01). 또한 RBT개성과 측정된 통화 상대자의 퍼스날리티 간에 유사한 성향이 있음을 발견하였다(r=0.753).

Two experiments were carried out in order to investigate the influence of Ring-Back-Tone(RBT) music on the evaluation of the phone-call receiver's personality in dimensions of Openness, Extroversion, and Neuroticism. In a preliminary experiment, the subjects listened to 17 RBT music stimuli in random order and assessed the personality associated with liking for each music using the 12 personality traits(N=15). Among the 17 RBTs, three were selected to be used in main experiment and they were distinguished from each other in terms of the tree personality dimensions(p<0.001). In main Experiment, it was hypothesized that the evaluation of phone-call receivers' personalities would be influenced by the personality of RBT music. Therefore, in the main experiment, the subjects were divided into four groups and each listened to one of the three RBTs or to a plain ringing tone(control group) until the receiver(the experimenter) answered the call. After interviewing the receiver, subjects evaluated her personality using the 12 traits. The empirical results provide evidence that the RBT influences the judgment of phone-call receiver's personality in terms of the three personality dimensions(p<0.001), supporting the hypothesis. In addition, it is found that there is a positive correlation between the personalities of RBT music and the phone-call receivers' personalities elaborating the affirmative result for the hypothesis(r=0.753, openness, p<0.01, r=0.753, extroversion, p<0.01; r=0.265, neuroticism).

In this paper, we implement PAMD(Positive Answering Machine Detection) for discrimination human and ARS. We are used Grunt detection, Glitch Noise detection and Tone detection for PAMD. It distinguishes voice signals from ring-back tone and glitch noise respectively. And as a second step, it judges whether human responses or ARS responses after integrating pattern changes like initial response period, the number of voice data, each time of voice data period and glitch noise. The accuracy is about 9375 in ASR and about 98％ in Mobile phone.

Noise can be defined as any undesired or loud sound. The sound level of mobile phone ring tones could be considered as noise if it is too loud on a specific situation. To classify a specific sound level of mobile phone ring tones as noise, it is useful to evaluate the mean opinion scores(MOS) on sound levels under some specific situations. The paper evaluates MOS on various sound levels (in dBA) of mobile phone ring tones, types of ring tone(bell/melody), and gender(male/female), location (street/office).
