Chef's voice is composed of audio clips of his voice from various episodes purposely spliced up poorly. This is intentional to make him sound out of his mind, as Isaac Hayes quit after allegedly being offended by the episode "Trapped in the Closet" which mocked Scientology, a religion he is a member of. Hayes died in 2008.
The speech given by Kyle at Chef's funeral appears to be influenced by Trey and Matt's negative feelings towards Scientology as well as Hayes' departure.

This is the last appearance of Chef (apart from his appearance in the crowd scene in the title sequence). From the next episode onwards, his appearance in the crowd scene is replaced by Darth Chef.
