Ludovic Plestan is a French actor and voice actor, born in Normandy and based in Saint-Brieuc, who has built a career in dubbing since 2014 while remaining a core member of the Quai Ouest theater company. His path to voice work was influenced by an early interest in the craft, sparked by a behind-the-scenes look at dubbing for The Muppet Show during his adolescence. He pursued formal training in dubbing from established figures in the field, including Sylvie Feit and Danièle Hazan.

Plestan's voice is characterized as a baryton léger or baryton-martin, a tessitura that sits between a baritone and a tenor. His dubbing work is primarily conducted at the AGM Factory studio in Rennes. The work is technically demanding, requiring him to synchronize his performance to pre-existing footage, often in isolation from other cast members. He describes it as a complementary but distinct discipline from stage acting, where a more natural vocal delivery is required compared to the projected voice of the theater.

His voice roles span a wide variety of productions. In animation, he has voiced a cat in the series Dans la toile, which aired on TV5 Monde. His work also includes dubbing for foreign-language productions. He provided the French voice for the character Bruno Lombardo in the Mexican telenovela Sortilegio, a long-term project spanning 90 episodes. In film, he dubbed actor Ed Helms in the 2018 television film Le Secret des Kennedy.

Beyond dubbing, Plestan lends his voice to documentaries, such as one on street art for France 3, and has recorded commercial voiceovers and technical tutorials for companies like Airbus. He also appears on screen as an actor, with roles including Jean Gicquel in the feature film Le réseau Shelburn.
