Akari listens to a continuous voice waveform in a Gynara sound studio.

TECHNICAL NOTE

Speech // ai.character-speech

How each Gynoid keeps her voice through a complete reply

All ChatterBox surfaces use the shared synthesis provider, retaining the selected character reference and language while rendering complete speech.

Production Practitioner Updated 2026-10-30

01 / WHAT

What it does

Text generation and speech generation are separate operations. A Gynoid's chosen reference identifies the cloned voice; the selected language and model remain fixed throughout that speech request.

02 / WHY

Why it works this way

Long inference can drift in delivery or hit the speech model's output ceiling. Internal passage boundaries keep synthesis manageable without shortening the member's completed reply.

03 / HOW

How it works

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.
