DESCRIPTION
eBook-speaker reads aloud eBooks and other text formats and even scanned documents using a
software speech-synthesizer. By default the tool espeak is used for speech output. eBook-
speaker can read from http://, https:// and ftp:// URLs using the tool wget. eBook-
speaker also can scan a documant by itself using the scanimage application.
A list of items on the eBook will appear. Press <ENTER> to start reading. When reading of
an item has finished, eBook-speaker will read the next item and the cursor will
automatically skip to that item, so that an attached braille-terminal will display the
name of that item.

KEYBOARD COMMANDS IN THE FILEMANAGER.
-b n | y | position
Set the initial break_on_EOL or position. After quitting eBook-speaker. This
setting will be saved and used as default for future books. It can be overruled
with the 'b'-command for each individual book. See the 'b' command.
-c eBook-speaker use tesseract for OCR by default. This option forces eBook-speaker to
use cuneiform instead.
-d audio_device:audio_type
eBook-speaker will play on this sound device of given audio_type. The value must be
of the form "audio_device:audio_type". Example: "-d default:alsa", "hw:0:alsa" or
"0:pulseaudio". This option overrules the value in the ~/.eBook-speaker/* config
file. Be sure the user is a member of the group "audio".
-h Print this usage message.
-H Show "hidden" files in the file-manager.
-i Ignore reading of the bookmark.
-l Deprecated. eBook-speaker now determines the file-type using the libmagic library.
-o language-code
The language code for OCR to use. (typically an ISO 639-1 two-letter code. See
<https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes>). If this option not is
specified, the language is determined according to the current locale.
-r resolution
By default the option "-s" will scan at a resolution of 400 DPI. With this option
one can force another resolution.
-s Scan a document using a hardware scanner and OCR it with either tesseract or
cuneiform.
-S Do not display the phrase-numbers passing during playback.
-t TTS-command
Be sure that the TTS reads from the file eBook-speaker.txt and that it writes to
the file eBook-speaker.wav. To add the TTS-command permantly one has to edit the
~/.eBook-speaker.xml file by hand.
-v Be more verbose, so one can se what's going on.
Examples:
• ebook-speaker some.epub -t "espeak -f eBook-speaker.txt -w eBook-speaker.wav -v nl"
• ebook-speaker some.epub -t "flite eBook-speaker.txt eBook-speaker.wav"
• ebook-speaker some.epub -t "text2wave eBook-speaker.txt -o eBook-speaker.wav"
SCREEN
The name and version of this program and the name of the author is displayed left aligned
at the top of the screen. The name of the current loaded book is displayed right aligned.
The second row of the screen displays the number of pages of the current loaded book (if
any), the current selected level and the total number of levels, the total number of
phrases and the current displayed screen and the total number of screens.
The next rows displays the title of the item, the first page of that item within brackets
(if there are pages) and the total number of phrases in this item. Items in higher levels
are indented. (Three spaces each level.) When "just reading this item" is active, a "J" is
viewed at the first column of that item.
The spoken phrase will be displayed on the bottom-line of the screen, so one can follow
along on a braille-terminal what he/she hears.

FILES
~/.eBook-speaker/
This directory contains the bookmarks in XML-format. Each file has the name of the
book and contains the name of the current item, the start-phrase of that item, the
current level, the desired TTS, the desired reading speed, the desired phrase-break
point and the current sink in the list of the available sound devices.
~/.eBook-speaker.xml
This file, in XML-format, contains a list of available TTS's. (See TTS EXAMPLES)
/tmp/eBook-speaker.XXXXXX
eBook-speaker makes use of a temporary directory. It is removed after quitting.
NOTES
An EPUB-book has two index-files for navigation, a NCX and an OPF file. eBook-speaker
tries to detemine which of these two files give the best result. But sometimes eBook-
speaker is not able to make the best choice. When in doubt use option "--N" to force the
use of NCX or "-O" to force the OPF.
