Automatic capture and population of task and list items in an electronic task or list surface via voice or audio input through an audio recording-capable mobile computing device is provided. A voice or audio task or list item may be captured for entry into a task application interface or into a list authoring surface interface for subsequent use as task items, reminders, “to do” items, list items, agenda items, work organization outlines, and the like. Captured voice or audio content may be transcribed locally or remotely, and transcribed content may be populated into a task or list authoring surface user interface that may be displayed on the capturing device (e.g., mobile telephone), or that may be stored remotely and subsequently displayed in association with a number of applications on a number of different computing devices.
