Is it possible to get percentage of accuracy of recognized text?

I need to recognize multiple languages (2 languages) and tesseract doesn't know exactly what language is when I put parametar -l lang1+lang2.

What I want to do is to scan with both languages separately, but I would need some percentage of accuracy to determine probability of language.

It's called "confidence" value in Tesseract terminology. hocr format output contains confidency values, at word level, I believe.

I have found w_conf attribute in .hocr file.

How should I interpret that value? Does high w_conf value means high accuracy?

Yes, its values range from 0 to 100.
