multiple languages?

[Guido Milanese]

I am trying tesseract and I find it very interesting. A quick
question: is it possible to use
tesseract for documents containing more than one language? Or, if not,
is this point planned for the future? Can we (normal users) be of any
help?

Thanks,
guido, italy

You could train to languages in one. It may even be possible through
the tools to merge them. Read the Wiki.

One thing. The more characters you can recognized the slower and less
you recognition percentage will be.

Yes, thank you, I had understood this approach of two languages in
one, but my question was a bit different (probably the phrasing of my
question was not clear). In some OCR programs, as Omnipage, you can
select a certain number of languages *at the moment* you need them,
not building "couples" or "groups" in advance. Being a linguist, I
need sometimes e.g. English + German + French, sometimes German +
Italian + Latin + French, and so on.
I gather this is not possible with Tesseract?

Thanks again for this excellent program!

Not currently. You would need to merge languages for every
combination.

Although it is a desirable feature, it is not currently supported to have multiple languages enabled. It might happen in a future release...

Is it possible to get the language that matched from the result? In other words, is it possible to use tesseract to recognize the font? Is this per character, per word or per page? How much slower is recognition when multiple languages are combined?

The multilanguage is working in tesseract-ocr 3.2.
The command line is:

tesseract imagename outbase [-l lang1+lang2+lag3]

(e.q. tesseract image1.tif imageOCR [-l eng+fra+deu])

All the best !

Tesseract cannot recognize what font is in use, but it does work for
various fonts. You would have to try languages in succession (not
together) to tell which language was matched, I think, although with
some coding you might be able to get at that. I believe the
combination of languages is quite a bit better than the time to try
them individually, but you'd have to test it, I think. Not all
languages are supported in combination.
