Muppeteers in outside voice roles

It's true that Muppet performers are not just voice actors when performing their Muppet characters. However, due to their facility with playing multiple roles, vocal dexterity, and other skills, several have lent their voices to outside non-Muppet/puppetry projects, including animation. The following list covers performers who have had significant regular speaking roles on one or more Muppet series.

To keep this manageable, it excludes any instances where a puppeteer supplied the voice only of a puppet or costumed suit character, or of animated characters on a puppet series they worked on. At present, video game work is often too extensive to document, involves voice matching celebrities, or playing numerous NPCs, and audio-only or live-action dubbing is also excluded. Resumes too lengthy to cover here are linked, or covered in summary on the article. Also excluded are professional voice actors who once or twice performed Muppets (such as Cynthia Adler).

Any additions should be verified through screen credits, official sites and resumes, or other reliable sources, and not Wikipedia or IMDb.

Lists are not intended to be complete or all inclusive. For those with more extensive voice credits, recurring or notable guest roles only are specified or a limited representative sampling, as they frequently doubled in one lines or bits
