speakulation
1. when someone with a microphone hijacks the peace and quiet of a public space with unwanted, unintelligible, or superfluous information.
I finally got settled in my seat in the back of the plane. I pulled out my book and began to get back into the complex and entertaining storyline. That is when the "speakulation" began spewing out of the speaker above my head. The flight attendant, then the pilot, then the flight attendant again, over and over every thirty seconds for most of the flight, I was bombarded with unintelligible, and unwanted information that actually hurt my ears to listen to.
speakulate
to speak not definitely but speculatively or assumptively.
Speak positively. Do not speakulate.
