Agreed. It hardly feels worth even reading through the paper since, from my perspective, it may as well just be made up. I can also write "Hey guys I made a good TTS it's really cool and great and the voices sound really natural" and put some samples together. If I never release any code or models or anything, it may as well have not been published.
The value of this stuff is going to zero. Don't worry about it.
Product over model.
Models and weights are a race to the bottom. Everyone is doing it and competing on data efficiency, methodology, MOS, etc. Groups all over are releasing their data and weights. It doesn't matter if Amazon doesn't, other labs will do it to get ahead and to get attention.
This is going to be entirely pedestrian within a year.
ElevenLabs is not a unicorn. It's an early-forming bubble.
