## Summary

Rohan Paul shares that VoiceArena released Joy, a dataset of 100,000 hours of unscripted two-person conversations across 10 languages. He says current voice AI mostly learns from LLM-written dialogue read aloud by TTS, so it never hears people talk over each other. The accompanying chart reports that an average hour of Joy has about 350 overlaps and 300 backchannels.

Unscripted calls are hard to collect at scale. 
Voice AI today mostly learns from fake dialogue written by LLMs and read aloud by TTS, so it never hears people talking over each other; 

Really curious how they kept the conversations going for 10 to 20 minutes.
