Method and apparatus for annotating a line-based document

A method for annotating a line-based document comprising:

• obtaining an audio data file comprising audio data of an audio representation of said line-based document, a plurality of audio time codes and a plurality of line identifiers associated with said plurality of audio time codes;
• detecting an audible document navigation command having a specified line identifier, and navigating to a desired position of said audio data based on said specified line identifier;
• detecting an audible annotation command during playback of a first line number, and capturing a corresponding audible annotation as an audio annotation file;
• and
• adding an annotation entry to an index file, said annotation entry comprising a first reference to said audio annotation file and a second reference to said first line number.

A method for annotating a line-based document comprising:

• in a first computer system, pre-processing a line-based document to obtain an audio data file comprising audio data, a plurality of time codes and a plurality of line identifiers associated with said plurality of time codes;
• providing said audio data file to a portable annotation device;
• in said portable annotation device,
• in response to line-based voice commands, navigating audio playback within said audio data file using said plurality of line identifiers in said audio data file;
• in response to audible annotation commands, capturing an audio annotation file for each new user annotation, and providing an annotation entry in an index file, wherein said annotation entry comprises a first reference to a respective audio annotation file and a second reference to a line identifier in said audio data file;
• providing a plurality of said annotation files and said index file to said first computer system;
• in said first computer system,
• using voice recognition to obtain a plurality of annotation text files corresponding to said plurality of annotation files;
• for each annotation entry in said index file, appending to a corresponding line number in said line-based document one or more links to respective audio annotation files and corresponding annotation text files;
• and
• providing a graphical navigation window comprising a plurality of links to said plurality of audio annotation files, a plurality of links to said annotation text files, and a plurality of links to line numbers in said line-based document.
