This chapter presents a review of the published literature relevant to our work. In producing audio renderings, we draw on prior work on structured electronic documents and the use of speech and non-speech audio in computer interfaces.
s:lit-doc-struct introduces work on recognizing document structure. We outline ongoing work on marking up document structure unambiguously and translating between different document encodings. s:lit-audio covers prior and ongoing work in the innovative use of audio in human-computer interaction.
