I got 100% easily, literally all the clean high quality voices are AI and all the voices that you can notice lower quality microphone are human. You don't even need to pay attention to how they pronounce
This is largely correct! When we launch a new game we're planning on distorting the AI voices, and adding background noise.
People speak with a robotic voice when they read. If the stats are to be trusted externally it would need a promise on the page that all human voices have been instructed to perform above the basic level of natural intonation - just like the bots have.
This is an interesting thought!
which voices are winning?
There isn't a strong pattern when narrowing to a single voice, but the ElevenLabs voices in general are much more easily mistaken for a human compared to any other provider we're currently using.
