The provider prepares speech text, renders sentence-aware passages of at most 240 characters sequentially, and joins compatible audio into one complete WAV. Each passage keeps the same reference, model, language and sampling settings. Akari's approved reference and English selection remain the intended inputs.
The shared method covers private Gynoid rooms, site-assistant roles, Interview Studio, Admin Operations, VN Copilot, authored VN recordings, Hybrid speech and character voice previews. Each surface retains its own admission, price and playback behavior.
Markup, control metadata and emoji are removed from spoken input while the saved transcript stays intact. A failed passage fails the operation rather than yielding a partially ready purchase. Ready paid audio replays from its original receipt; older recordings are not silently regenerated. New synthesis uses the revised cache contract.
