The Scottish singer called for shows such as X Factor and The Voice to give contestants the freedom to create their own music.
She claimed the shows were using contestants for their own gain, rather than to promote their musical success.
She said: "I just wish there was more new song writing on those shows. And when they exploit dreams, that's heartbreaking.
"Don't do that to people just so we can watch it on TV."
The singer was also reportedly offered the chance to replace Jessie J on The Voice last year, but now seems unsure about the idea.
She said: "If people get a chance to do something they dream of, you can't be snobby towards that."
Emeli's debut studio album Our Version of Events reached top spot in the charts, as well as scooping several awards including the Brit award for Best Album.
She has also penned tracks for stars such as Susan Boyle and Leona Lewis, as well as big-name Americans Alicia Keys and Rihanna.
The former Glasgow University student will return to the campus later this month as part of the Radio 1 Academy workshops at the Queen Margaret Union.

Other Scottish musicians joining Emeli by hosting a session include rockers Biffy Clyro and fellow singer-songwriter Nina Nesbitt.
