How to tell Siri > when I am done talking, eg, over steady background noise? Sometimes the ambient background noise in my environment is enough to keep Siri engaged after I've just asked Siri for something. Siri can hear my voice clearly atop the background noise, as evidenced by her transcription of what she's heard so far -- the problem is, Siri keeps on listening until there is quiet.

Examples of the type of background noise I am referring to include TV shows, boisterous guests, music, lawnmower, construction, etc.

Similar to this question regarding telling Siri about newlines, is there a way to issue some kind of military-style &lt;&lt;\over>> or &lt;&lt;\end transmission>> or unix-style &lt;&lt;\EOF>>to let her know that there is nothing else to hear, and to process my input as-is?
If you press and hold the Home button down and keep it down the whole time you are asking Siri the question, letting go of the Home button will signify "end of question." It takes a little getting used to but it works great. This is not exactly what you asked for but it solves your problem.
