Effects of the Program for Developing Oral Communication Expressiveness on university radio announcers: a pre/post intervention study.

Purpose: To analyze the effects of the Program for Developing Oral Communication Expressiveness on announcers of a university radio station.

Methods: This is a pre/post intervention study. The Program for Developing Oral Communication Expressiveness was implemented with eight announcers in eight 2-hour meetings. Participants were evaluated before and after the program using self-perception instruments, auditory-perceptual judgment, and acoustic analysis of their voices during standardized readings. Statistical analysis included descriptive and statistical inference methods with a significance level of p < 0.05.

Results: The announcers' self-perceived diction and voice improved after the program. Half of the pairs evaluated improved in the auditory-perceptual judgment of reading, emphasizing voice quality, speech, and interpretation. The acoustic analysis found reduced fundamental frequency of speech, increased articulation and elocution rate, and decreased speech intensity.

Conclusion: The program considerably improved aspects of the announcers' voice and speech, highlighting the importance of specific training programs to improve radio communication skills.
