A language listing is also provided on the Nuance web site.
The option Detect single language automatically removes the need to select languages. It is
designed for unattended processing when documents or forms in different languages are
expected. OmniPage then examines each incoming page and assigns a single recognition
language to the whole page. That means this feature is not suitable for pages containing
multiple languages.
The program chooses from the languages with dictionary support that use a latin-based
alphabet (meaning Russian and Greek are excluded) plus optionallyAsian languages . Choose
from three language groups:
• Latin-alphabet languages (choose it to see the enabled languages)
• Asian languages (Japanese, Korean and Chinese – Traditional and Simplified)
• Latin-alphabet and Asian languages.
When this feature is enabled, no manual language selection is possible and the option Veri fy
language choices (see below) is not available.
In addition to user dictionaries, specialized dictionaries are available for certain professions
(currently medical, legal and financial) for some languages. See the list and make selections in
the OCR panel of the Options dialog box.
Asian language recognition
Four languages with Asian alphabets are supported: Japanese, Korean, Traditional Chinese
and Simplified Chinese. The ideal font size for body text is 12 points, scanned at 300 dpi,
resulting in characters with around 48 x 48 pixels. Minimum is 30 x 30, that is 10.5 points at
300 dpi. For smaller characters, 400 dpi should be used. Asian texts can be horizontal (left-to-
right) or vertical (top-to-bottom, right-to-left). Operating systems supported by OmniPage 18
can handle Asian languages, but if East Asian language support was not selected during
system install, it must be added from Control Panel / Regional and Language Settings /
Languages / Supplemental language support / Install files for East Asian languages. You may
be required to insert a Windows system disk.
The four Asian languages are listed alphabetically with the others in the Options/OCR panel.
You should select only one of these languages at a time and avoid a multiple selection with
other languages. Asian OCR can handle short embedded English texts without English being
explicitly set; this is not designed for longer English texts or for texts in other Western
languages. Vertical text is typical in Japanese and Chinese - English may be embedded there
