This would potentially destroy any hands free benefit a virtual assistant would have, back in the day of the secretary (the roll these talking Pringles tubes are trying to emulate) the bossman CEO or whatever would press a button on the office intercom to talk with his secretary. I think virtual assistants would benefit from a simple push-to-talk style input so they don't misinterpret a pause as a stop.
