- Voices —
PATCH /voices/{id}: voice owners can now update accent and gender. Voice creation validates language. Invalid voice UUIDs and pronunciation-dictionary IDs return 404 instead of ambiguous errors.
- PVC model routing — PVC voices require a dated model ID (e.g.
sonic-3-2026-01-12) instead ofsonic-3. See Pro Voice Clone.
