Is it true that is linda hunt the voice of edna in the incredibles based on the following text?

Edna was created by screenwriter and director Brad Bird to explain how superheroes obtain their costumes, a topic he believes is rarely explored in superhero films convincingly. Bird also decided to voice the character himself after several actresses originally considered for the role found it difficult to replicate Edna's unique accent. The director understood that, in addition to demonstrating fashion expertise, the character would also need to be proficient in the fields of science, engineering and technology in order to create costumes capable of withstanding the trials of superheroic activities, and ultimately conceived her as a short, confident character of both German and Japanese descent based on these countries' reputations as small yet powerful nations. Inspired by Q from the James Bond franchise, Edna is widely believed to have been primarily based on costume designer Edith Head, although there continues to be constant speculation as to whether or not other real-life celebrities inspired Edna, particularly Vogue editor-in-chief Anna Wintour and actress Linda Hunt.
