Donald Duck talk

Buccal speech, is an alaryngeal form of vocalization which uses the inner cheek to produce sound rather than the larynx. The speech is also known as Donald Duck talk, after the Disney character Donald Duck.

Despite the association, Donald Duck's current voice actor Tony Anselmo reveals that buccal speech isn't how the character's voice is created: "Most people believe Donald's voice is created by squeezing air through the cheek. I can’t reveal how it’s actually done, but it is definitely not by squeezing air through your cheek. The Hanna Barbara character Yakky Doodle is done that way. Donald Duck is not".
