We rolled out the Sonic-3.5 voice model across all bots. The upgrade brings sharper intonation on emphasized words, lower time-to-first-byte for new utterances, and more natural pacing on longer responses.
No action needed. Existing bots pick up the new model automatically. Voice names, IDs, and the cloning pipeline are unchanged.
