When I speak to an agent, siri, or whatnot, I am always worried that they will assume I'm done talking when I'm thinking. Sometimes I need a many-seconds pause. Even maybe a minute… For Sire and such, I want to ask something simple "Hey Siri, remind me to call dad tomorrow". Easy. But for Claude and such, I want to go on a long monolog (20s, a minute, multi-minutes).
To me, be the best solution would be semantic + keyword + silence.
I have the same issue. It gives this very weird minor sense of public speaking anxiety where I almost feel the need to write down what I'm about to say, which negates the whole purpose. Only solution I've found is using push-to-talk with some of the system wide STS applications.
"It will be sunny with a high of 10 degrees. Over"
"Thank you. Over and out."
Just add some noise and Push-To-Talk and it will be great for ham radio enthusiasts!
