On any Android phone [versions 2.2 or greater] hold down the *search key* until the “speak now” dialogue appears and then say, “NOTE TO SELF”, immediately followed by your verbal reminder (e.g.,”new Muppet movie premiers this weekend”).
Google immediately converts your audio message to text and gives you options to select, “To, Subject, CC, or BCC”.
Selecting “To” auto populates your Gmail address allowing you to share your verbal brain storm (or not).
