1 Introduction

As a bridge between the media and the audience, the emotional expression of the host plays a crucial role in information transmission and program effectiveness. In radio and television programs, the host is not only a transmitter of information, but also a communicator of emotions [1]. The host integrates their emotions into the program through various means such as voice, intonation, rhythm, and body language, establishing a deep emotional connection with the audience. This not only enhances the program's appeal, but also increases audience participation and satisfaction, thereby achieving a positive interaction between the media and the audience. Therefore, analyzing the application strategies and impacts of emotional expression in broadcasting and hosting not only helps to enhance the professional competence of broadcasting and hosting practitioners, but also provides useful references for the production and dissemination of radio and television programs.

2 The Significance of Emotional Expression in Broadcasting and Hosting Art

2.1 Responding to Media Changes

With the rapid development of technology, the media industry is undergoing unprecedented changes. The emergence of emerging technologies such as virtual anchors and artificial intelligence has brought enormous challenges to traditional broadcasting and hosting. However, in this transformation, emotional expression has become an indispensable core competitiveness for broadcasting and hosting. Emotional expression is the bridge between broadcasting hosts and audiences to establish emotional connections. In the new era of digitization and networking, the channels for audiences to obtain information are more diverse, but emotional communication between people has become increasingly precious. Through delicate and sincere emotional expression, broadcasting hosts can overcome the limitations of screens and establish a deep emotional bond with the audience. This not only enhances the attractiveness and infectiousness of the program, but also allows the audience to feel warmth and care in the fast-paced life.

2.2 Shaping public Opinion Direction

In the media environment, broadcasting and hosting are not only transmitters of information, but also shapers of public opinion guidance. The host deeply influences the public's attitude, values, and public opinion through carefully polished language and appropriate emotional input [2]. When dealing with sensitive or controversial topics, broadcasters and hosts can report with a balanced and objective attitude, avoiding exacerbating conflicts and promoting the public to view issues with a rational and peaceful mindset. At the same time, the host enhances the public's awareness and recognition of values such as morality, justice, and fairness by conveying positive energy and promoting social justice, thereby shaping a positive and uplifting social atmosphere. In the context of globalization, broadcasting and hosting also undertake an important mission of cross-cultural communication. Through language and emotional expression, they build bridges of communication between different cultures and social groups, promote mutual understanding and respect of information, and enhance international understanding and friendship [3].

2.3 Building the Cornerstone of Communication

In the era of information explosion, misleading and biased information often breeds easily. As the gatekeeper of information, broadcasting hosts have the responsibility to screen and verify information to avoid the spread of false information. The professional competence and sense of responsibility of the host can ensure the authenticity and reliability of information, providing the public with a trustworthy source of information. Emotions are the bridge of human communication, capable of crossing language and cultural barriers and directly touching people's hearts. Broadcasting hosts can enhance the attractiveness and infectiousness of information through delicate and sincere emotional expression, enabling listeners to resonate and identify emotionally while receiving information, and increasing public trust and dependence on the media. In the rapidly changing media environment, broadcasters guide the public to engage in rational and open discussions through language and emotional expression, which helps promote the healthy circulation of social information and the positive dissemination of cultural values, contributing to social harmony, stability, and cultural prosperity [4].

3 The Application Strategy of Emotional Expression in Broadcasting and Hosting

The precise grasp of emotional tone, as the cornerstone of the program atmosphere, can directly affect the audience's emotional experience and emotional resonance. The host needs to carefully consider and set an appropriate emotional tone based on the nature, content, and target audience of the program. For example, in news reports, for major social events or catastrophic news, the emotional tone should be solemn and serious to reflect respect for the event and sympathy for the victims; In entertainment programs or variety shows, a relaxed and lively emotional tone can be used to create a joyful and pleasant atmosphere. When setting the emotional tone, the host also needs to consider the overall rhythm of the program and the audience's acceptance. Overly heavy or relaxed emotional tones can cause discomfort or aversion in the audience. Therefore, the host needs to find a balance point in setting the emotional tone, so that the program can convey the required information and emotions while maintaining the audience's attention and interest. By accurately grasping the emotional tone, the host can more effectively guide the audience's emotions, enhance the infectivity and attractiveness of the program, and also help shape the host's personal image and style, enhancing the audience's sense of identity and loyalty.

The flexible application of language skills in broadcasting and hosting requires hosts not only to

have rich vocabulary reserves and accurate language expression abilities, but also to be good at using various rhetorical devices such as metaphors, parallelism, and exaggeration to enhance the vividness and imagery of expression [5]. Meanwhile, the clever use of intonation, pace, and pauses is also crucial. By flexibly utilizing intonation changes such as rising tone, falling tone, flat tone, and melody, as well as adjusting the pace reasonably, the host can create different emotional atmospheres and guide the audience's emotional direction. Making appropriate pauses at key information points or emotional transitions can give the audience time to think and reflect, making the expression more layered and rhythmic. In addition, the vividness and fun of language cannot be ignored. The host should enhance the fun of the program and increase the audience's sense of participation by using a variety of vocabulary and inserting humorous elements. However, when using these language techniques, the host also needs to pay attention to maintaining a sincere and natural expression style, avoiding overly rigid or artificial expressions, to ensure the true transmission of emotions and resonance with the audience. In short, the flexible application of language skills is an indispensable and important skill in broadcasting and hosting, which can not only improve the quality of programs, but also bring more pleasant and profound audio-visual experiences to the audience.

The effective use of nonverbal symbols, such as body language, facial, expressions, eye contact,

and voice characteristics (such as changes in sound quality, volume, and pace), can convey rich emotions and information silently, further deepening the audience's understanding and perception of the program. Body language is an important carrier of emotional expression. A proper gesture or natural movement can instantly convey the host's emotional state, such as joy, sadness, surprise, or determination. Through body language, the host can more intuitively express their attitude towards the program content and enhance emotional resonance with the audience.

In addition, facial expressions are the most intuitive and vivid part of nonverbal symbols. A sincere smile and a caring gaze can instantly bring the host and the audience closer, allowing the audience to feel the warmth and sincerity of the host, enhancing the affinity of the program, and improving the audience's sense of participation. Eye contact is also crucial in broadcasting and hosting. The host establishes contact with the audience through eye contact, conveying attention, understanding, and respect, making the audience feel valued and listened to, which helps enhance the interactivity of the program and makes the audience more engaged in participating in the program. Voice characteristics are also an indispensable part of nonverbal symbols, and changes in the host's tone, volume, and pace can all affect the audience's emotional experience. By adjusting the sound characteristics, the host can better adapt to different program atmospheres and emotional needs, creating an emotional atmosphere that is more in line with the program content. In broadcasting and hosting, hosts should pay attention to the use of nonverbal symbols, constantly improve their nonverbal communication skills, and bring more diverse audio-visual experiences to the audience.

4 Analysis of the Influence of Emotional Expression on Broadcasting and Hosting Effectiveness

4.1 Enrich Program Content and Enhance Artistic Value

Emotional expression is not only an auxiliary tool for information transmission, but also the key to enriching program content and enhancing artistic value. The host uses subtle emotional processing techniques such as intonation, pace, and pauses to concretize abstract themes, imbuing the program with profound connotations. This allows the audience to experience the intersection of emotions and thoughts while receiving information, making the program content more full and enhancing the depth of thought. Meanwhile, emotional expression can create a unique artistic atmosphere for the program, allowing the audience to immerse themselves in a specific emotional environment and enjoy the aesthetic experience brought by art. In "The Reader", CCTV host Dong Qing perfectly integrates personal emotions with the program content through unique intonation, speed, pauses, and body language, not only allowing the audience to feel the warmth of the program, but also deepening the theme of the program. At the same time, each reading chapter in 'The Reader' is closely connected to the guests' life experiences or emotional stories, which not only enriches the content of the program, but also makes the reading more infectious and artistic. Whether it's heartwarming family programs, romantic love stories, or solemn current affairs reports, broadcasters and hosts can create a matching atmosphere through delicate emotional processing, allowing viewers to appreciate the program while also feeling the flow of emotions and the charm of art, and gaining a deeper aesthetic experience.

4.2 Promote Emotional Resonance and Psychological Identification Among the Audience

Emotional expression can transcend language and cultural boundaries and directly touch people's hearts. The host uses precise emotional manipulation and communication to make the program content not just a pile of information, but a story full of warmth and color. When the host uses voice to interpret the story and emotions to interpret the event, the audience can feel the emotional fluctuations more deeply, thus resonating in their hearts. This resonance not only deepens the audience's understanding and memory of the program content, but also stimulates their emotional reactions, such as emotions, joy, anger, or thinking, making the program not only a visual and auditory feast, but also a spiritual touch. In news reporting, the appropriate integration of emotions can make cold news events flesh and blood, allowing the audience to not only understand the facts, but also feel the brilliance of human nature or the warmth and coldness of society. For example, Zhu Guangquan, the host of CCTV News, has won the love of a large audience with his humorous and infectious emotional expression. In news broadcasting, he is adept at using language skills and nonverbal symbols to present news content to the audience in a more vivid and interesting way, allowing the audience to feel emotional transmission while receiving information. This emotional expression can quickly bring the host and the audience closer together, allowing the audience to feel the host's sincerity and enthusiasm, thus making it easier to generate emotional resonance. In variety shows, the host's humor, wit, or warm care can quickly bring the audience closer, create a relaxed, joyful, or heartwarming atmosphere, and allow the audience to find solace in laughter or tears. Through emotional expression, broadcasting hosts not only convey information, but also emotions, making the program more infectious and influential, becoming a bridge connecting the hearts of hosts and audiences.

4.3 Inspire Audience Participation and Enhance Interactive Effects

In today's increasingly diverse media environment, audience participation and interaction have become important criteria for measuring the success or failure of a program. Emotional expression, as an important skill in broadcasting and hosting, can stimulate emotional resonance among the audience, thereby enhancing their willingness to participate. When the host expresses emotions in a sincere, enthusiastic, or infectious way, the audience is often infected and generates strong emotional reactions, prompting them to participate more actively in the program, whether through messages, comments, voting, or social media sharing, they are willing to express their opinions and feelings. In addition, emotional expression can enhance the interactivity and fun of the program, allowing the audience to gain more enjoyment and satisfaction during the participation process. For example, in "Happy Camp", the famous host of Hunan TV, He Jiong, won the love and resonance of the audience with his deep and delicate emotional performance and humorous hosting style. He is adept at integrating his emotions into the program through various means such as voice, intonation, rhythm, and body language, establishing a deep emotional connection with the audience. He Jiong guides the audience to share their stories or experiences through emotional questioning and interactive segments. He expressed emotions in a sincere and infectious way, deeply touching the audience and generating strong emotional resonance. After feeling this emotional resonance, the audience is more willing to actively participate in the program, expressing their opinions and feelings through messages, comments, votes, and other means. The host guides the audience to share their stories or experiences through emotional questioning or interactive activities. This emotional communication not only brings the host and the audience closer, but also makes the audience feel valued and respected, making them more willing to continue paying attention to and participating in the program, and allowing the audience to gain a richer emotional experience during the participation process.

4.4 Shaping Brand Image and Enhancing Personal Charm

Every excellent broadcaster has their own unique way of expressing emotions, and this uniqueness is an important component of their personal style. Emotional expression is not only the transmission of language, but also integrates the host's personality traits, cultural background, life experiences, and understanding of the world, which is the externalization of the host's inner world. Through emotional expression, the host can showcase their unique temperament and charm in the program, thereby shaping a distinct personal style. For example, CCTV host Sa Beining is good at using humorous and witty emotional expressions to create a relaxed and pleasant atmosphere in the program, which is deeply loved by young audiences; Hunan TV host He Jiong is skilled at using deep and delicate emotional performances to touch people's hearts and resonate with the audience. These personalized emotional expressions not only make the host stand out among many peers, but also help the program form a unique brand characteristic and attract a large number of loyal viewers. More importantly, the formation of emotional expression style is the result of the host's long-term practice and experience accumulation, reflecting the host's professional competence and personality charm. A host with a distinct personal style can easily establish emotional connections with the audience, form a stable audience group, and lay a solid foundation for the long-term development of the program. Therefore, emotional expression is not only a means for hosts to showcase their personal charm, but also a key factor in shaping program brands and maintaining audience relationships. Through continuous cultivation and improvement of emotional expression ability, the host can gradually form their own unique style and become an irreplaceable presence in the audience's heart.

5 Conclusion

In summary, emotional expression plays an irreplaceable role in broadcasting and hosting. With the rapid changes in the media environment and the diversification of audience demands, emotional expression has not only become a key factor in improving program quality, but also plays an important role in enhancing audience interaction, improving communication effectiveness, and shaping the host's brand image. By accurately grasping the emotional tone, flexibly using language skills, emphasizing the use of nonverbal symbols, and maintaining true and moderate emotional expression, broadcasters can effectively convey emotions and enhance the attractiveness of the program to the audience. Broadcasters and hosts should pay attention to the strategies and skills of emotional expression, constantly improve their ability to convey emotions, and adapt to the needs of media development in the new era.
