The search for Marta Volpiani as an anime voice actor reveals that she is a Brazilian actress and dubbing artist, not a Japanese voice actor. She is best known for providing the Brazilian Portuguese voice for the character Dona Florinda in the live-action comedy series Chaves and other roles performed by Mexican actress Florinda Meza.

In the context of anime and animation, Marta Volpiani has voiced several characters in Portuguese dubs of Japanese series. One of her notable anime roles is as the Queen (credited as Rainha) in the series Hana no Ko Lunlun, which is known in Brazil as Angel, a Menina das Flores. This matches the example of her playing the character Malicia, suggesting the role name varies by localization. Her other work in animation includes providing voices for characters such as the Sra. Moroboshi in Urusei Yatsura (known in Brazil as Turma do Barulho), Nadia in Entaku no Kishi Monogatari: Moero Arthur (Rei Arthur), Vivian in an unspecified work, and Celina and Rosa in the dubbing of Chespirito's comedy sketches.

Her career in dubbing began through her proximity to a studio following the end of a contract for a television novel. She sought a test and was initially cast in a small role for a Mexican novel before receiving an invitation to voice Dona Florinda. Her performance as Dona Florinda has become culturally significant in Brazil, with the actress herself noting that the success of Chaves marked a distinct era in Brazilian dubbing history. For her work on the redub of Chaves, she received a nomination for the Prêmio Yamato in 2006 in the category of Best Protagonist Dubbing Actress.
