Some Definitions

    • Another sound type—belongs to Microsoft
  • Text-to-Speech (TTS)
    • Text that is made audible by a computer-generated “voice”

DAISY vs. …

  • E-text
    • DAISY has structure: headings, pages

    • DAISY has navigation, bookmarks

So Many DAISYs…

What’s inside a DAISY?

  • z3986 folder

Where’s the text?

  • Not all DAISY books are the same
  • DAISY will vary a bit depending on
    • How it was produced
    • How much mark up was done by the producer

DAISY “Flavors”

    • Format used by Bookshare
  • Structured Audio
    • Audio only
    • Format used by RFB&D (Learning Ally)
  • Audio and Full Text
    • Can be created with commercially available publishing tools

Text Only…but It’s Audio

  • Text Only DAISY books
    • Are played with a DAISY player that does text to speech (TTS)
    • Are smaller files because they do not already contain audio
      • Audio is BIG!!
    • Can be used with whatever “voices” you have

Why can’t I see it?

  • Audio Only DAISY books
    • Are usually human narration
      • Recordings of a person reading aloud
    • Adding the text to these books requires the text and audio to be synchronized
      • Kind of like captioning
    • Usually have a “navigation structure” that can be seen

Best of Both Worlds

  • Full Text Full Audio DAISY
    • Has both text that can be seen and sound that can be heard
    • Audio comes as part of the book
      • Do not need TTS or voices
    • Audio may be human narration or machine generated
