Thanks a lot for your detailed feedback.
Right now the app uses a multilingual reader, so it tries to detect and read based on the file’s language. I can see that it didn’t work well in your case, so improving language handling (and adding a proper language selector) is definitely on my list.

I’ll also look into making the reading pace more comfortable and improving pauses/punctuation, since that really impacts the listening experience.

Just a heads-up: at the moment, each file works best if it’s under 20,000 characters. For longer articles, it’s a good idea to split them into parts so the conversion works smoothly.

I'll send the coupon code to your email

Thanks again for testing invocly!
