It depends on the aspect of broadcasting you’re interested.  

       To be a host, you must: 1) think fast and be creative; 2) speak clearly; 3) know the interest and needs of your audience; 4) have a distinctive style.  

       To be a newscaster, you must: 1) think fast and know the focus of news events; 2) speak clearly and be succinct to news report; 3) care about current events domestically and abroad; 4) develop professional knowledge for the category you cover such as politics, sports, economy, arts and culture, and transportation.

        The very first step is to practice enunciation.

        It’s not that difficult in training. To practice, find an article and read it out aloud; make sure to speak every single word loudly clearly and smoothly and then ask your teacher to help correct your mistakes. Because radio broadcasting is about communicating with sound, you must “speak” everything. Therefore, you must cultivate “courage” and “ability to express yourself clearly” from a young age. It’s even better if you read a lot of books and are curious about a lot of things because having a lot of common knowledge is one of the fundamental qualifications for a broadcaster.   

        The most basic qualifications for a host are the ability to enunciate clearly, thinking fast, being creative, having a distinctive voice, reacts fast, and articulate. The difference between categories of programs such as music, interviews, service and others require professional knowledge in music as well as a degree of sophistication, which makes the program more interesting and listenable.
