Well, that was pretty simple.
I always emphasized in my course that making a video for your app is important! But sometimes, I didn't have time to invest in it myself, even not taking the time to contact the professionals and communicate with them...
And then I found elevenlabs.io - Wow! That voice commentary sounds better than some of the medium level Fiverr offers there are out there!
-- Wrote a 30 seconds commentary script about my app and why it's the real dealio -- (Funny enough the app is also all about AI - https://bit.ly/gptAndro)
Took the audio file, uploaded to d-id.com, selected that mega generic female model, and exported the video (a far-sighted dude without glasses watching it via his phone will surely think this is 100% genuine!)
Google Play A/B Tested the video (with VS without)
The Result: 8% higher conversions to downloads!
Conclusion: Lots of people are going to lose commentary and presenter jobs... and it will be easier to create those as well. Then again, it's not quite yet "acting level" material, both in voice and visuals aspects.
