Voice input is captured by a microphone that is connected to a standard sound card. Ink is also captured using an input device, such as a mouse, a tablet pc or the pen / stylus of a personal digital assistant (PDA). The captured voice input is converted in the soundcard to speech data and forwarded to an indexer module, where it is temporally indexed to ink obtained from an ink capture module via an input device. The indexed ink / speech data is then stored in a memory module for subsequent user access. When the ink is selected by a user, such as via a pen / stylus of the PDA, the speech data that is indexed to the ink is played, i.e., the multi-modal data is retrieved. The listener is able to enter ink on a document based on the content of the voice input.
