Claim:
An apparatus for annotating a line-based document comprising lines of text, said lines of text being associated with corresponding line identifiers, said apparatus comprising: an audio codec coupled to an audio output device; a processing unit; a computer readable medium having computer program code embodied therein for annotating said line-based document with at least one audible annotation received in connection with audio data generated using said line-based document, wherein said computer program code is configured to cause said processing unit to provide: a voice recognition function, said voice recognition function configured to detect one or more audible document navigation commands and one or more audible annotation commands from audio input; a navigation function responsive to a detected document navigation command received from said voice recognition function, said detected document navigation command comprising a first of said line identifiers associated with said lines of text of said line-based document, said navigation function configured to determine an audio time code for said audio data corresponding to said first line identifier and to direct said audio codec to play back said audio data from said determined audio time code; an annotation function responsive to a detected annotation command received from said voice recognition function, said annotation function configured to capture an audible annotation via said audio input and to store said audible annotation as an audio annotation file; and an index generator configured to add an annotation link entry to an index file to link said audible annotation to a second of said lines of text of said line-based document, said annotation link entry having a first reference to said audio annotation file and a second reference to said second line of text.
