Hi,

Suffice to say that someone (not me) is researching this possibility at the moment.

Cheers,

Joseph

Hi, I’m using this addon on win10 with the latest NVDA, the best thing of this addon is to read the subtitles and on screen text automatically. If possible, please add this functionality to NVDA core, so that it can be used with Win10 ocr.

Hello everyone,

I took a look at this add-on, and I'm afraid this one isn't really compatible with recent NVDA releases and other issues were found (no wonder it is labeled a "beta" at this time). Specifically:

* OCR engine: it uses OCR engine found in Windows 10. Therefore unless you are using Windows 10, you won't be able to use this add-on at all (you can configure things, but the thing that enables this add-on is missing on older Windows releases).

* It uses code fragments that are no longer supported in newer NVDA dependencies (specifically, wxPython).

Thanks.

Cheers,

Joseph
