Anna,

</div>
<div class="">My sympathies are with you concerning setting up Tesseract and Audiveris. It seems a bit arcane.</div>
<div class=""><br class="">
</div>
<div class="">What I did was to install tesseract via VietOCR3, which was developed to recognise Vietnamese script. </div>

</div>
<div class="">My tesseract setup (v. 4.1.1) is now somewhat strange:</div>

<div>If this doesn’t help (and it hardly counts as useful instructions, I admit) I have found the main developer of Audiveris (Hervé Bitteur - <a href="mailto:herve.bitteur@audiveris.com" class="">herve.bitteur@audiveris.com</a> ) extremely responsive and helpful
in the past. I suspect the same may be true of the developer of VietOCR3, Quan Ngueyen - <a href="https://sourceforge.net/u/nguyenq/profile/" class="">https://sourceforge.net/u/nguyenq/profile/</a> , though you will have to contact him/her through SourceForge.</div>
<div><br class="">
</div>
<div>Another admission: I haven’t done anything with this for a year or two. My idea was to set up a system which would take output data from Aruspix concerning location of bits of text, especially lyrics, and feed them as tiny tasks to Tesseract, then merge
the recognised lyrics appropriately into the Aruspix MEI. As you might imagine, this is one of those projects that seems a lot simpler before you start, and I only got to the stage of recognising some ‘lyrics’ from 16c motets as text which I was (sometimes)
able to identify using *very* approximate matching and a certain amount of manual guesswork with the Liber Usualis. </div>
<div>BTW all this was without any training for the fonts, styles, abbreviations and strange text-glyphs you find in 16c prints.</div>
<div><br class="">
</div>
<div>I think this is a valid Special Interest Sub-group idea for MEI, as it really is the next thing that is needed for corpus-building in early music.</div>
<div><br class="">
</div>
<div>Also, BTW, with a working tesseract installation, Audiveris does a pretty fair job with lyrics in ‘normal’ music.</div>
