document. The navigation bullets can be used to quickly navigate through a text. Tap a navigation
bullet and the ClearView Speech will start reading the selected text zone. The number of the
navigation bullets represent the most likely order of the text. The speech reads the zone with
navigation bullet number 1, followed by navigation bullet number 2, and so on.

3. The ClearView Speech Menu
This chapter will familiarize you with the ClearView Speech Menu.
3.1 Activating and closing the menu
To activate the menu, tap on the grey Menu button. The Menu button is the most left button on the
Button Bar marked with the character “M”. To close the menu, tap the button marked with the “X”
at the bottom right corner of the menu. Any changes made in the menu are automatically saved.
3.2 Using the menu
The ClearView Speech menu contains two rows of three large buttons. To activate a button, tap
the button once. Activating a button will either change a setting, or open a submenu or list. If a
button is greyed out, the option is not available.
The menu contains the following buttons:
•Save
•Voice
•Open
•View
•Delete
•Settings
3.3 Save
To save a document, open the menu and tap the blue “Save” button.
First you will be asked in what format you would like to save the document:
•Document: this is the standard Speech format
•e-PUB: This is an e-reader or Daisy compatible format
•DOCX: Use this document if you would like to edit the document on a PC with Microsoft
Word
•MP3: Selecting this format will save the document as an MP3 audio file.
When saving a document as an audio MP3 file, you will need to select the reading voice. The list
of voices to choose from are the Nuance voices of the selected language, or the voices of the
languages detected if automatic language detection is enabled.

Optelec ClearView Speech

Not all voices can be used to save as an MP3 audio file. The available voices are limited to only
the Nuance voices. In case no Nuance voice is installed, the MP3 button will be greyed out and
this option is not available for the selected language.
Only one voice will be used for the entire MP3 file. Automatically switching between languages
within an MP3 audio file is not supported.
Saving a document in MP3, DOCX or e-PUB takes longer than the standard format. Especially
saving a multipage document in MP3 format could take several minutes.
After you selected the format to save the document in, you will be asked if you would like to save
your document with a voice label.
If you wish to save a document without a voice label, select “No”. The document will be saved
using the first line of the document as the name of the document. If you would like to add a voice
label, select “Yes”. You will hear a beep after which you have 5 seconds to record a voice label. At
the end of the recording you will hear another beep sound. The document will be saved with the
recorded voice label.
When the document is saved, the ClearView Speech will ask if you would like to append more
pages to the document.
If you select “No”, the menu will be closed showing the document again. If you select “Yes” you
can start appending more pages to the document by placing the page in the document outline and
tapping the screen once to capture the new page. To stop appending more pages to the
document, press the close button marked with the “X”.
The ClearView Speech will prompt you with the question if the captured pages should be
processed. If “No” is selected, the conversion to text will be done while reading the document. If

Optelec ClearView Speech
English 15
“Yes” is selected, all pages will be processed before returning to the document reading mode. This
process may take several minutes, depending on the number of pages of the document.
By default a document will be saved on the SD card delivered with the ClearView Speech. If you
wish to save your document on a USB drive, connect a USB drive to the ClearView Speech. When
a USB drive is connected the document will be saved automatically on the drive.
3.4 Open
To open a document, open the menu and tap on the green “Open” button. Select the “Document”
button to see the list of saved documents, showing the most recently saved document first. To open
and view pictures, select the “Pictures” button.
Scroll the list of documents or pictures using the scroll bar on the right side of the screen. If you
touch the screen and slowly move your finger over the documents, the title of the document will be
read aloud. To select a document simply tap on it.
In the list with documents or pictures, tap the document or picture you wish to read or view. The
menu will be closed and the document or picture will be opened. Pictures can be magnified. It is
also possible to open text documents in “txt” format or photos from a USB stick. To open documents
in “txt” format, the document should be located in the root of the USB stick or SD card.
3.5 Delete
To delete a document, open the menu and tap on the “Delete” button to see the list of documents.
Select the document you wish to delete.
You will be prompted to confirm to delete the document. To delete the document, select “Yes”. To
cancel deleting the document, select “No”. Both choices will return you to the list of documents.
3.6 Voice
This menu item lets you select your reading voice and language. To select another reading voice,
tap the “Voice” button.

Optelec ClearView Speech
16 English
The ClearView Speech will switch to the next configured voice. If adjusting the reading voice
results in a change of language, the menus will automatically change to the same language. To
add or delete voices and languages from the voice selection, please refer to paragraph 3.8.1.
Note: In case automatic language detection is enabled (please refer to paragraph 3.8.2.), this
button only changes between voices of the detected language. For instance, if the detected
language is English this button will only change between the different English voices. With
automatic language detection enabled, you will not be able to change the language of the menu.
To change the menu language, either: 1) disable automatic language detection, 2) scan a
document in your preferred menu language and change the voice once in the menu, or 3) switch
back to ClearView mode, activate Speech mode, go into the menu and select your menu
language.
3.7 View
By selecting the “View” button, the “View” menu
will be opened. The “View” menu contains three
buttons:
•Color
•Mode
•Highlight
3.7.1 Color
