O.K., here is the idea of the Voice Widget.
First, steps to create a widget:
1. You create a voice widget, that will act as a shortcut, with predefined parameters, like the time of saving voice event. You can select the desired, general time determiners, like "today, tomorrow" etc. and the hour and minute of the future voice events.
2. Then you can use a predefined widget to add a voice events by just saying something. The event will be stored in the calendar at the selected time. No need to enter/dictate the time and other parameters.
In other words, widget will spare you entering (or dictating by voice) the complicated parameters like hour, minute, date - instead, you use a predefined, general time determiners.
What is the benefit of such widget ? Well, think that you drive a car every day. When you commute, you can save new events for future reference (memos), these events can be reviewed after you are back home.
Hope it explains the matter. I will make a video presentation describing the Voice Widget in the near future.
