"Felicia woke up with a voice that is barely recognizable. The turquoise carpet, singing and long days in a dry arena, shouts of joy and talk, talk, talk have taken their toll," SVT's press spokespeople wrote in an email to Swedish media representatives in Vienna.
However, this is not due to any illness affecting the Swedish artist.
"Thankfully, she is not ill in any way, but has been advised not to speak at least on Wednesday. Unfortunately, this means that we have to cancel the planned interviews today," SVT wrote.
Felicia advanced to Saturday's final in the Eurovision Song Contest from Tuesday's semi-final with her entry "My System".
