3.4.3. Pages.
If a DAISY book has been marked for page navigation, the reader can
go direct to specific pages or can skip backwards or forward a page
at a time. 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. The reader cannot add pages.
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 top
of the 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 independently of the other navigation
structures. For example, diagrams, tables, points of note, safety
information and so on. When it used carefully, it could be extremely
useful. Groups cannot be 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 may be
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.
