To make this possible, the producer of the book must include the page
markers when they create the book. The pages will be automatically
numbered from 1 upwards starting from the beginning of the recording.
Pages cannot be added by the reader.
NOTE: Page markers in a DAISY book should always be placed at the start
of the text on the relevant print page and not at the bottom, where the
page number often appears. This means that, when you go to a page in
the finished DAISY book, you will always be at the start of that page when
it starts to play.
3.4.4. Groups.
The group marker can be used to identify items in the book that the
reader might wish to go to independent of the other navigation structures.
For example, diagrams, tables, points of note, safety information and so

specified by the reader and must be inserted by the DAISY book producer.
3.4.5. Phrases.
When the book is being recorded, the audio files are automatically divided
into segments called "phrases". The recording software will decide on
where a phrase starts and ends based on the amount of silence between
one piece of audio and the next. The length of silence permitted before a
new phrase is created is called the "pause time" and can be adjusted by
the person making the DAISY recording. In order to break the audio up
into phrases that are not too long or short, a fast reader might require a
short pause time and a slower reader a longer pause time. When the
recording is finished, the reader can use the phrases as an additional
navigation feature.
3.4.6. Sections.
A Section refers to the segment of audio between one heading and the
next. A section is generally made up of a number of phrases but can have
as few as one phrase. Each section will have a heading and an associated
