Read Aloud in Greek?

Can it read aloud a Greek text?

When you indicate "a Greek Text," I take it to mean the NT. For the mobile platform to my knowledge the options are limited. There is https://www.logos.com/product/153692/the-new-testament-in-the-original-greek-byzantine-textform-2005

otherwise, I have John Schwandt The Audio Greek New Testament. I don't believe it is available anymore. If you have it in your library you are fortunate. He reads from NA27.

And that's about it. The BYZ is a big file and will require a lot of space. I recommend you stick with the desktop options.
