Voice-over is the process of reading and recording texts prepared for visual or audio content used for promotional and advertising purposes. These works are utilized in television commercials, radio advertisements, promotional films, and increasingly in digital advertising campaigns. Additionally, professional voice-over work is required for special projects such as phone system recordings and closed-circuit system announcements. Voice-over work is performed by voice actors who have received specialized training in this field. Voice-over services encompass diction, intonation, and technical knowledge. Therefore, possessing an ideal voice tone alone is not sufficient to become a voice actor. A voice actor should have the necessary knowledge and skills in areas such as diction, pronunciation, voice styles, and text analysis.
