In my first course, I used text to voice for a couple of lectures. It was 2 years ago, at that time, you could really immediately hear it's robotic. That's why I didn't use it more than that, just to add some extra pitch to the course. Then I only had one comment saying that it was annoying. After, I asked a few other students and they said it was fine for them. Just for reference: "Aldila Yanri 3:03 AM Hi Vlad, the automated voice was fine to me. That was clear. I didn't have any problem with that." That course had around 300 students since it became paid, and the rating was 4.55. Just one more recent comment for reference: "Neha Tyagi 2:08 PM Hi Vlad,I am almost switching my carrer from banking to Auditing. So its a perfect course for me. I was looking for something which clear my basic concept and it really does. Within few hours learnlot" - sorry I kept the grammar issues in the quote. The course was also added to Udemy for Business. Now the course is blocked. And since I lost the original raw files used for creating videos, the course is gone, just a useless disc space on Udemy servers. I'll explore alternative platforms to publish it there. In my new course, I used a new AI-based tool and it's amazing, unbelievably realistic. You just need to put extra commas and pauses here and there to make it sound fully natural. These should be customers who make the choice. If they don't like it they will be putting low ratings and ask for the money back.

My course was just blocked because I used text to speech. That's ridiculous. The latest AI engines do it better than myself. That requirement probably comes from an old era when it was just unpleasant to listen to those. But these times have passed. If no one tells you, you will only realise that it's robotic after a few paragraphs if not slides. And after you will enjoy listening, wondering how fast technologies evolve. Now I have to spend hours per lecture setting it up and re-recording hundreds of times. Because I don't like the intonation, then I don't like my accent, then my gf makes a noise in another room etc. The funny thing is that the quality might actually deteriorate as a result, as sooner or later I might give up trying to make it perfect. But nothing to do, will have to go for it, don't want to lose the time already invested.
