 What you get: 

Takes no for an answer: 45% fewer wrong confirmations on the one-word turns 
that decide a call, and 52% fewer in heavy background noise. 
Background voices stay out: with voice_focus on and a second talker in the 
room, word error against the caller drops 62%. 
32 languages, one endpoint: wrong-language words fall 95%, so most agents can 
leave detection on automatic. Fourteen languages are new. 
Turns end when the caller is done: end-of-turn precision is up 3.8 points at 
the same recall, with median endpoint latency unchanged at 537 ms. 
Speaker labels improve mid-session: set speaker_labels_revision_interval_ms 
and revisions arrive during the call, not only at the end. 

 Same price as Universal-3.5 Pro. The change is the model name: set 
"speech_model": "universal-3-6-pro" on your existing Realtime API connection.
