Optelec ClearView Speech

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
“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
possible to open photos from a USB stick.
3.5 Delete

Optelec ClearView Speech
English 15
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.
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.

buttons:

enable up to maximum five languages. To do this, go
to the “Voice” selection menu, and enable a
language by selecting at least one voice per
language. Do this for a maximum of 5 languages. Now make sure the language detection is
enabled in the “Options” menu.
Note: In case the ClearView Speech Is not able to detect the language, the langage of the menu
is being used. If English is one of the selected languages, the ClearView Speech will use an
English voice and will ignore the menu language.

3.8.2.4 Column Filter
This option contains two settings:
- Ignore incomplete columns
- Include incomplete columns.
When “Ignore incomplete columns” is enabled, the

read all detected text on the page. The “Ignore
incomplete columns” is the recommended and default setting, offering the most comprehensive
text recognition. The “Include incomplete columns” will try to detect all text on the page, but may
result in incomprehensive text at the beginning or end of the document.
