방송진행자는 메시지의 촉매 역할을 하는 커뮤니케이터(communicator), 즉 전달자에 해당한다. 매스미디어에 종사하는 뉴스 진행자를 비롯한 음성 전달자는 수신자의 이해력과 정보 전달량의 최적 접점을 찾는 고도의 테크닉을 요구하는 작업을 수행해야하는데 메시지의 효율적인 전달은 메시지 자체의 콘텐츠도 중요하지만 그 구성과 전달 방식도 대단히 중요하다는 것을 알 수 있다. 그 중에서도 음성언어 전달에서 전달 속도는 수용자의 이해 측면에서 중요한 변인이다. 이처럼 방송 메시지 전달에서 속도가 갖는 의미가 매우 중요함에도 불구하고 수많은 관련 학자들은 커뮤니케이션 모델을 제시하면서 시간적인 개념을 간과했다. 또한 송신자와 수신자 즉, 화자와 청자 간의 관계에 있어 의미 공유 내지 호감도에 대한 측면도 간과해 왔다. 따라서 본 연구의 목적은 뉴스 전달 속도가 수용자 인식에 어떠한 영향을 미치는지 규명하는 것이다. 이를 위해 연구문제1에서는 뉴스 전달 속도를 바탕으로 전달 속도 차이에 따라 수용자가 인지하는 유사언어적인 변별력의 차이와 선호도, 뉴스에 대한 이해도 차이, 나아가 방송 진행자의 공신력에 전달 속도가 어떤 영향을 주는지 알아보았다. 연구 방법은 1939년 일제 강점기 이후에서부터 2008년도 4월 현재에 이르기까지 30개의 뉴스 녹음 자료를 측정 분석하여 1분당 음절수로 측정된 전달 속도의 변화 추이에 대해 알아보았다. 이후 속도의 변화를 세 가지 유형으로 분류하여 느린 속도는 1분당 300음절로 설정하였고, 이후 구간별 속도 간격을 60음절씩 차이를 두어 보통 속도를 360음절, 그리고 빠른 속도를 420음절로 설정해서 같은 내용으로 속도만을 달리한 실험용 뉴스를 제작하였다. 이후 20대의 대학생과 4, 50대의 그들의 부모집단을 대상으로 세 가지 속도의 실험용 뉴스를 들려주고 설문에 응답토록 했다. 연구 결과 수용자 인식 차이에 대한 조사 결과 첫째, 뉴스 전달속도가 빨라질수록 수용자들은 유사 언어적 차원에 있어 부정적인 평가를 하고 있었다. 즉, 뉴스전달자의 정확한 발음과 안정적인 전달력, 그리고 장음과 단음에 따른 단어의 의미 변별력 등 모든 차원에서 뉴스전달 속도가 빨라지는 것은 부정적인 영향을 미치고 있었다. 둘째, 뉴스전달 속도는 수용자들의 뉴스 이해도에도 매우 유의미한 차이를 유발하고 있었다. 유사언어적인 인식차원과 유사하게, 뉴스전달 속도가 빨라질수록 수용자들은 뉴스에 대한 이해도가 현저하게 떨어지는 것으로 나타났다. 뉴스속도가 빨라질 경우 수용자들의 이해도는 매우 낮은 수준으로 하락했다. 결국, 뉴스가 수용자들에게 얼마나 효과적으로 전달되었는가를 나타내는 이해도 차원에서도 뉴스의 전달속도는 매우 중요한 변수로 확인된 것이다. 셋째, 뉴스전달속도에 따라 뉴스에 대한 선호도에도 매우 큰 차이가 나타났다. 뉴스의 전달속도가 빨라질수록 수용자들은 쫓기는 느낌은 물론, 공격적인 인상을 받는 것으로 나타났다. 또한, 유창하거나 지적인 느낌, 그리고 친근감을 준다는 평가적 요소에서도 속도가 빨라질수록 부정적인 태도를 유발하고 있었다. 끝으로, 뉴스에 대한 수용자들의 공신력 평가차원의 경우 뉴스 전달속도가 빨라질수록 수용자들은 부정적인 평가를 내렸다. 빠른 속도의 뉴스에 노출된 수용자들은 보통이거나 느린 속도에 비해 현격하게 낮은 수준으로 공신력 평가를 했다. 결국, 수용자들이 인식하는 뉴스에 대한 공신력에도 뉴스의 전달속도가 중요한 설명변수로 작용함을 확인했다. 본 연구는 뉴스 전달 속도의 효율성 측면뿐만 아니라 말속도가 문화와 밀접한 관계가 있다는 전제에서 전달 속도의 시대적인 변화를 알아보고 수용자에 대한 배려, 수용자와의 관계, 방송전달 환경 변화를 다루었다는 점에서 의의가 있다고 할 것이다. 그리고 그동안 매체연구나 수용자 연구에서 상대적으로 소홀했었던 수행(performance) 차원에서의 연구로서 커뮤니케이션 전체 과정에서 전달 속도가 왜 의미가 있는지 환기시켰다는 점에서 의미를 부여할 수 있다고 할 것이다.

The broadcasting messages are delivered through vocal language and have the time limitation and the characteristics that delivery is carried out in one-time. And the effective delivery shall be carried out by minimizing the occurrence of noise during the process. Likewise, the voice messenger, including news casters engaging in mass media, shall carry out the work requiring the high techniques, in which the optimal interface between the recipient` comprehension and the quantity of information, so it is well known that the composition and the delivery methods are also very important in the efficient delivery, though the contents of the message itself is important, taking account into the above mentioned conditions. Among the conditions, it may be said that the reading rate in vocal language delivery is the important variable in the aspect of recipient` comprehension. Despite the fact that the reading rate in the broadcasting message delivery holds the huge significance like this, lots of relevant researchers overlooked the concepts in terms of time in the presentations of communication models, failing to notice the aspects of sharing the meaning and favorable impression according to the relationship between the sender and receiver, that is, the speaker and the listener. Therefore, the purpose of this study is to inquire into what influence the reading rate of news delivery has on the perception of user, and as for the research question 1, it was attempted to examine what influence the reading rate has on the differences in the power of discrimination in terms of paralanguage recognized by recipients, the preferences, the differences in comprehension of news and the public trust to the broadcasting hosts ultimately, according to the difference in reading rates based on the reading rate in news delivery. As for the research methodology, the number of syllables per minute was measured by analyzing the 30 audio taped data of news, beginning from the year 1939, under Japan`s colonial rule, to April of 2008, to the present, examining the trend of change in the reading rate of news broadcasting. And then, with the change in the reading rate classified into three types, the slow reading rate was established as 300 syllables per minute, and with the reading rate gap in each section separated by 60 syllables, the common reading rate was established with 360 syllables and the rapid reading rate was established with 420 syllables, so that the experimental news might be created using the same content, but performing with the different reading rates. And then the college students in their 20s and their parents in their 40s to 50s in age were allowed to listen to the three types of experimental news, and they were questioned with the questionnaire. The total participants in the experiment were 312 people, and the most scales showed the credibility level, recording 0.7. As the result of research, it was found out that users` recognition difference survey; first, as the reading rate of news delivery became, the users appeared to gave more negative evaluation in the paralanguage level. So to speak, the fact that the reading rate of news delivery was becoming faster had the negative effect on every level, such as the accurate pronunciation and the stable delivery of the news casters and the discrimination power related to the words on the basis of the long and short syllables. Especially, the news delivery with high reading rate was recognized as the worst, in the level of how stably the news was delivered to the users. On the other hand, as the reading rate was getting slow, the paralanguage level of news was recognized more positively. In conclusion, it was found out that the reading rate of news delivery did not have any significant influence on the recognition of users` paralanguage in case it was common or slow, but the news was not delivered well to the recipients in case it was faster than the normal speed. Second, the reading rate of news delivery was inducing the meaningful difference considerably in the users` comprehension of the news. Showing the similarity with the recognition level which is related to the paralanguage, as the reading rate of news delivery was getting faster, it seemed that the recipients` comprehension degree of news was remarkably going down. When the news in a slow reading rate was exposed, the user`s comprehension degree appeared to be the highest, and there was no big difference in comprehension in the common speed, but when it was getting faster the user`s comprehension degree went down to the lowest level. In conclusion, the reading rate of news delivery was identified to be a very important variable even in the comprehension level, which shows how effectively the news was delivered to the users. Third, the big difference occurred in terms of preference of the news, according to the reading rate of news delivery. The level of news preference was divided into the sense of speed, which is sort of a negative level, and the factors in terms of evaluation. And as the speed was getting faster, it induced the negative attitudes even in the evaluation elements such as the fluency, sense of intellect and the intimacy. Especially, the users exposed to the high reading rate of news delivery showed the very low level of preference, compared to the exposure to the common or slow speed. On the other hand, the slower the reading rate of news delivery, the higher preference to the news appeared, compared to the other level of speed. Finally, in case of the recipient`s evaluation level of public trust for news, as the reading rate of news delivery was getting faster, the recipients gave more negative evaluation. As the reading rate of news delivery was getting slower, the user`s evaluation level of public trust for news appeared to the most positive, anyway the user`s evaluation level of public trust for news at the common reading rate of news delivery did not show big difference. However, the recipients exposed to the high reading rate of news delivery evaluated the news as remarkably low level of public trust, compared to the exposure to the low speed. In conclusion, it was identified that the reading rate of news delivery was functioning as the important explanatory variables for the public trust of news which is recognized by the users. This study might have the significance from the viewpoint that the change in the reading rate of news delivery in terms of time was examined and the consideration for users, the relationship with users and the environmental change in the broadcasting delivery were dealt with, on the assumption that the speed of speaking, as well as the efficiency aspects of the reading rate of news delivery, has the close relationship with the culture. And also it might have the significance from the viewpoint that the reason why the reading rate had the significance in the total communication process was refocused as the study on the level of performance, which had been neglected relatively in the studies about media or recipients.
