1. General Information

1.1 Preamble

Members and Friends of the DAISY Consortium are committed to deliver the best possible reading experience for blind and print disabled users. To create this rich reading experience, the books must be feature-rich and the reading systems must utilize the features to provide an enhanced reading experience. With this goal in mind, the DAISY OK Self-Certification Process sets minimum requirements for books and reading systems. We strongly encourage book producers and reading system developers to go beyond what is set as the minimum.

1.2 Definitions

The following abbreviations, acronyms, phrases, and terms are used in this standard as defined below.

1.3 DAISY OK Philosophy Statement

  1. DAISY OK defines the requirements for certification of DAISY players/reading systems and DAISY Digital Talking Books.  DAISY OK  further considers the importance of the relationship between books and players/reading systems and how this relationship should provide the best reading experience possible. DAISY OK is therefore committed to encourage, enhance, guide and nurture the relationship between organizations which produce Digital Talking Books (DTBs) and player/reading system manufacturers. The DAISY OK philosophy will promote cooperative relationships and mutually heightened awareness of the book producer and player manufacturer goals. This cooperation could and should challenge both book producers and player manufacturers to work together to innovate beyond the current DAISY OK requirements.
  2. As more Digital Talking Books (DTBs) are produced, and as more players/reading systems reach the market place, the need to provide clarification and information about DTBs and players/reading systems has become evident.To meet this need, the DAISY Web site includes a DAISY OK area where:

2.0 DAISY OK Reading Systems

2.1 Introduction

DAISY players need to provide a "rich" reading experience by implementing basic functionality to be "DAISY OK".

Table of Contents

2.2 Required Functionality
(what all playback devices must have in order to be classed as "DAISY OK")

(*Link) "Online Documentation"

Provide a link to the reading system description on your web site.
Reading System developers must provide a link to the reading system description on their company/organization's web site.

(*1.) "NCC and/or NCX navigation"

Support NCC and/or NCX navigation and nested levels, that is, render DAISY 2.02 and/or DAISY/NISO books
The DAISY Player can navigate between multiple hierarchical book elements allowing the reader to move from chapter to chapter, section to section, page to page or even jumping directly to a specified page number whereas a commercial MP3 player can navigate at only one level defined by the contents of the MP3 file.

(*2.) "Page navigation"

Support sequential navigation by page, forward & back (when pages are present in the DTB)
The DAISY player can go directly from one page to another page, one after the other sequentially, forward and/or backward.

(*3.) "Remembers last reading position"

Retain the location of last reading point
The DAISY player will begin to play at the point where the user had stopped reading when playback is stopped, and, when the book has been removed from the reading system and reinserted at a later time; location of last reading point must be retained when multiple books are read, and, if the book is part of a multi-book CD.

(*4.) "Reads book title"

Provide access to the book title
This ensures that the first audio heard when a DAISY book is inserted is the book title, and that when a book is reinserted that the title is announced first, regardless of the playback start point (where the user last played that DAISY book).

(*5.) "Reads sequentially"

Render the book in the correct reading sequence, as defined within the DAISY DTB by the DAISY producer
If the user does nothing else but insert the book into the player, the DAISY book will play from beginning to end, in the correct order.

(*6.) "Next event movement"

Support navigation by next/previous SMIL event, that is, support SMIL level navigation; next audio in same par or to another par, depending upon the book; this may be by text reference (sentence by sentence)
This allows the user to move forward (or back) at defined intervals within the audio. This could be by word, phrase, sentence, paragraph or a mixture of all of these, depending upon how the DAISY book has been produced.

(*7.) "Stop and resume"

Allow stop and start, that is, pause/resume functionality which maintains the last reading position.
When playback is stopped the reading system will, when the start button is pressed, begin to play from the point where playback was stopped.

(*8.) "Forward and Reverse"

Supports rapid forward and reverse movement in time through audio in the DTB.
This feature provides similar functionality to the Fast Forward and Reverse in analogue tape players.

(*9.) "Stable playback"

Incorporate as much robust playback as possible, rendering valid DTBs as intended by the producer without crashing under normal circumstances.
If a valid DAISY book contains features unsupported by the player (for example, MathML), the player will continue to play and will not fail. Players will incorporate error recovery; if a player encounters an error in a book, the player will at a minimum and wherever possible, provide audio information about the problem and/or will play the book to the extent possible.

(*10.) "Where am I"

Report current reading position
The user can get information about the point in the DAISY DTB where he or she is reading, for example, how much of the book has been already read, and how much remains to be read.

(*11.) "Bookmarks"

Support insertion and navigation of user defined bookmarks within the current reading session.
The user can place markers, which will allow returning to thus marked passages in the book.

(*12.) "User manual"

Provides accessible basic user manual
An accessible user manual is provided with the reading system.

Table of Contents

2.3 DAISY OK Reading Systems Advanced Features:

In addition to the DAISY OK requirements, the above software and hardware reading systems may have some of the following advanced features:

2.3.1 Navigation

(N1) "Simplified or advanced keypad"

Simplified or advanced keypad
The user interface (key configuration) for the product is identified to be for simple (leisure reading ) or advanced (study materials) usage. The button description provided for hardware reading systems would inform the user if the buttons have one or more functions, if a complete number pad (for page number input) is included, and how the keys are haptically differentiated.

(N2) "Navigation by page"

Supports sequential previous and next page navigation by blocks of multiple pages
Holding a key down or a combination of keys allow the user to move through the DAISY DTB quickly by groups of pages within the structure of the book.

(N3) "Go-to Page"

Direct numeric page navigation
The user is able to go directly to a specific page number by entering the page number using the keypad buttons.

(N4) "Text navigation"

Uses the text source document for control of local reading
The reading system uses the text source document for local reading control. Reading by paragraphs, sentences, words, or other text structures are supported.

(N5) "Accessible remote control"

Supports a simple remote control device
The reading system supports a simple remote control device (i.e. play, pause and rewind). This feature may improve accessibility for people who have difficulty using their hands to operate these controls on the player.

(N6) "Bookshelf"

My Library, or Bookshelf
The user can search for all of the DAISY books saved to the computer. This applies only to software reading systems.

(N7) "NCC & NCX"

Renders both NCC and NCX
This is a "dual-spec" reading system that will play DAISY 2.02 and DAISY/NISO books.

(N8) "Simple searching"

Supports simple text searches
The reading system can search for exact strings of text.

(N9) "Fuzzy logic search"

Supports sophisticated fuzzy logic searching
The reading system implements a sophisticated search which may include non-consecutive text, word derivatives (i.e. finds "develop", "developping", etc.), finds synonyms (i.e. finds "house" or "home") and ranks the importance of matches.

Table of Contents

2.3.2 Advanced Reading Experience Functionalities

(R1) "Table reading mode"

Support of table reading mode
Reading system uses the "textual content document" for control and presentation of tables in the DTB

(R2) "List reading mode"

Support of list reading mode
Reading system uses the "textual content document" for control and presentation of lists in the DTB.

(R3) "Basic MathML support"

Basic support of MathML in DAISY
This reading system relies on the alttext and/or altimage attributes of the math element to provide a rendering to the user.  A basic MathML reading system does not incorporate native understanding of MathML structure and semantics. User preferences, navigation, and synchronized highlighting of subexpressions within the math element are not supported.

(R4) "Advanced MathML support"

Provides advanced support of MathML in DAISY
This reading system has a native understanding of MathML structure and semantics that allows it to provide a dynamic presentation of the textual, visual and/or audio components of the mathematics.  User preferences, navigation, and synchronized highlighting of subexpressions within the math element are typically supported.

(R5) "Skippability"

Supports skippability
The user can adjust the player to skip or play structures defined as skippable elements (e.g. pages, footnotes, sidebars producer notes) as defined in DAISY 2.02, and DAISY/NISO.

(R6) "Moves on after error"

Reports error and moves to next readable portion of the DTB
The reading system encounters an error in the book, announces it and instead of abandoning the book, it searches for the end of the erroneous passage, from where it continues to read.

(R7) "Bookmarks"

Bookmarks are saved for each book
Allows the setting of a point of reference or interest in the DTB and saves these bookmarks for each book. Functionality should include insert bookmark, delete bookmark, and navigate the bookmark list.

(R8) "Section bookmarks"

Can use bookmarks to mark the beginning and end of sections
This allows the reader to highlight entire passages or sections to be reviewed later.

(R9) "Time jump"

Provision of a time jump navigation mode
This allows the reader to skip through the narration at set time intervals.

(R10) "Variable speed"

Variable playback rate
The speed of the narration can be accelerated or slowed down without distorting the sound of the voice.

(R11) "Sleep timer "

Sleep timer stops playback
After a user determined time, without a key being pressed, the reading system will stop playing the DTB.

(R12) "Uses Resource file"

Utilizes DAISY/NISO resource file when available
The Resource File supplies text and/or audio segments and optional images, that can assist the reader in using a DTB. Its use is optional, unless escapable or skippable structures are enabled in the DTB.

(R13) "Enhanced forward and reverse"

Supports rapid audible forward and reverse movement in time through the audio in the DTB.
This feature provides innovative movement through the audio with audible feedback taking advantage of digital capabilities.

In the case of a full text, full audio book, the user has the choice of either listening to the recorded audio or the synthetic speech rendered by the software reading system.

(T3) "Choice of synthetic voices"

Allows the user to select and assign different synthetic speech voices for the book content and the reading system software prompts
In the case of a full text book, the user has the choice of using different synthetic speech voices for the DTB and the audio information of the software reading system.

(T4) "Word highlighting"

Supports word by word highlighting (in TTS mode)
In the case of a full text book, the user has the possibility of every single word being "highlighted", therefore advancing word by word through the text.

(T5) "Spells selected word"

Supports spelling of the currently selected word& (in TTS mode)
In the case of a full text book the user can have selected words spelled using synthetic speech.

(T6) "Dictionary lookup"

2.3.6 Sample Book Capabilities

(SB1) "A2D converted"

Reads Sample Book #1: Converted from an analogue talking book
This is a DAISY OK DTB with, at a minimum, audio and two methods of navigation; the audio has been converted from an analogue (tape) recording. It has an NCC/NCX navigation file which includes, for example, chapter headings, phrase navigation, and may include pages.

(SB2) "NCC/NCX digital audio, pages"

Reads Sample Book #2: Digitally mastered: audio, NCC/NCX file and pages
This is a DAISY DTB which is an original digital master production. It has an NCC/NCX navigation file which may include part and chapter headings etc., pages, skippable elements (such as pages and footnotes) and any other elements that the specifications (DAISY 2.02 and DAISY/NISO) support.

(SB3) "Full text digital audio"

Reads Sample Book #3: Digitally mastered: full text, full audio
This is a DAISY DTB which is an original digital master production. It has an NCC/NCX navigation file which may include part and chapter headings etc., pages, skippable elements (such as pages and footnotes) and any other elements that the specifications (DAISY 2.02 and DAISY/NISO) support.

It also includes the complete electronic text of the original print publication, but does not contain audio.

3. DAISY OK DTBs

3.1 Introduction


A DAISY DTB can be valid, and yet may not be "DAISY OK", and it is understood that not all valid Digital Talking Books (DTBs) produced by each producing organization will necessarily be "DAISY OK". Producing organizations should expect that some of their DAISY collection may not meet the DAISY OK DTB required functionality.

A DAISY OK book must provide an enhanced reading experience, beyond what linear navigation in a commercial non-DAISY reading system (player) can provide. The structure of a DAISY OK DTB must be meaningful and provide navigation which corresponds to the structure of the original publication. See the DAISY Structure Guidelines.

Commercial digital audio books support simple linear navigation, from one audio track to another. A DAISY OK DTB must have two or more "types" of navigation. A DAISY OK DTB must provide the user with more than one way to navigate the book. (See the Required Functionality for Navigation below.)

Table of Contents

3.2 DAISY OK DTB Required Functionality
(what DAISY books must have to be classed as "DAISY OK")

(Link) "Online Documentation"

DTB producers must provide a link to their organization's DAISY DTB production specification on their web site.
DAISY DTB producers must publish their Production Specification on their web site, providing their clients/patrons/customers with a clear description of what features are incorporated into each of the different types of books produced. These Specifications must stipulate the types of DAISY books produced by the organization or company, and state whether page mark-up is included in the various types of DTBs (as defined in the DAISY Structure Guidelines).

(*1.) "Is valid"

Must be valid
The DAISY 2.02 or DAISY/NISO Validator report must indicate that the DTB passed the validation process, with no errors identified.

(*2.) "Navigation"

Each DTB must provide a minimum of two or more types of navigation: navigation by levels (1 through 6), by page, and/or by 'phrase'.
Possible combinations of types of navigation include:
  1. Two structural levels, for example, Parts and Chapters
  2. One structural level plus page navigation
  3. One structural level plus smil (phrase/paragraph) navigation

(*3.) "Page navigation retained"

If the original source document contains page numbers, then the DAISY DTB must be produced with page numbers as presented in the original source. Page navigation is always preferred, as the second type of navigation, to phrase navigation.
It is understood that some books or source documents do not contain page numbers or may in some other way not lend themselves to more than one type of navigation. When this occurs, the "Navigation" or "User" Guide in the DTB must explain this deviation from the organization's published Specification.

(*4.) "Print structure retained"

Same structure as original printed book
The book must reflect the structure of the original print source (publication) and therefore may not, for example, reflect the tape or track configuration of the original tape master when a DAISY book has been converted from an analogue recording.

(*5.) "Audio titles first"

Single initial segment for book and section titles
For DAISY 2.02 the audio of the book title and NCC section titles should be contained in a single segment and that segment should be the first segment. This enables reading systems to properly announce the book title and NCC section titles.

(*6.) "Structure description"

Structure and user navigation
The description should be at level 1 within the structure of the DTB. This information should be placed consistently, from DTB to DTB, in the same location within its own NCC or NCX near the beginning of the book.

Table of Contents

3.3 DAISY OK DTB Advanced Features:

(DTB1) "MathML support"

MathML support
MathML is intended to facilitate the use of mathematical and scientific content on the Web, and for other applications such as computer algebra systems, print typesetting, and voice synthesis. MathML can be used to encode both the presentation of mathematical notation for high-quality visual display, and mathematical content, for applications where the semantics plays more of a key role such as scientific software or voice synthesis.

(DTB2) "Table reading"

Table reading mode
When tables are correctly marked up, the column and row heading information can be accessed by the end user

(DTB3) "Enhanced table reading"

Enhanced table reading mode
As in (DTB2) plus - In this mode, each cell in the table can be read in either a linear or non-linear style. The option of cell identification (row header and/or column header) will be given while moving through the table either vertically or horizontally using the player/reading systems navigation controls.

(DTB4) "Skippability"

Support for Skippable structures
Elements of the DTB that are marked as "skippable" allow the end user to optionally listen to or not listen to them. Footnotes, optional producer notes, sidebars, and the page numbers are examples of parts of a book that may be skippable

(DTB5) "Escapeability"

Escapeability (DAISY/NISO only)
Escapeability allows the user to direct the player to leave or escape from an element marked as 'escapeable' (e.g. table, list, footnote, sidebar) and to resume reading at the point directly following that element.

(DTB6) "Resource file"

Resource file (DAISY/NISO only)
These files could for example contain individual audio files and text which are associated with structural navigational elements in order to announce these elements, i.e. "chapter", "page", "section" and "part", allowing reading systems to announce/display "chapter, page, section" instead of "level1, level2, level3"

(DTB7) "Images"

Images (with descriptions)
Images and their audio descriptions are part of the DTB

(DTB8) "Audio/text synch"

Synchronization of text and audio at a minimum to the paragraph
The text and audio of the DTB are synchronized so that the text is highlighted as the audio is played. At a minimum, a highlighted paragraph corresponds to the audio played. Greater granularity, for example at the sentence level, may be possible and may be very useful for some users. Sentences in the text are highlighted as the corresponding audio is played. Synchronization at the word may be possible and may have applications in, for example, language learning books.
