## Summary

Voice Arena introduces Turing TTS, an evaluation measuring how often human listeners mistake AI-generated speech for real human speech. In its tests of leading TTS models against human speech, the best model fooled listeners only about 10% of the time. The post argues the community should examine whether blind pairwise naturalness evaluations are enough to measure progress in voice AI.

The next breakthrough in voice AI might not be another model taking the #1 spot. It might be a better understanding of what we should be measuring. Voice Arena is pushing that conversation forward.
