"American Idol" executive producer Nigel Lythgoe put out some theories about his show’s recent ratings dip during a telephone press conference Tuesday.

Lythgoe accused two rival singing competitions, NBC’s "The Voice" and fellow Fox show "The X Factor,’ of "feeding" from his show’s talent pool, according to The Hollywood Reporter.

He implied the talent pool for "Idol" is being diluted, while at the same time viewers appear to be growing fatigued by the proliferation of singing competitions on TV, according to the story.

Despite his criticisms, Lythgoe said he thinks "The Voice" has a "fun format" and he likes the chemistry between judges Adam Levine and Blake Shelton, the piece notes.
