Direct & render

Direct each line

Select any line to open the Performance Tuning panel. This is where you shape the read: the note the voice follows, the pacing around it, and the voice settings for that character.

Controls in the panel

Control	What it does
Performance note	The direction the voice follows for this line (tone, emotion, delivery).
Pause after	Overrides the chapter’s default silence after this specific line.
Speed & pitch	Voice settings that apply to every line spoken by this character in the book.
Generate Preview	Renders a free preview of the line so you can hear a change before committing.
Re-render this line	Regenerates just this line; charges only for the audio regenerated.

Direct, don’t dictate: a short note like “wry, conspiratorial” shapes the read more naturally than rewriting the text.

Edit the text or speaker

You can edit a line’s text or reassign its speaker inline. Edited lines are flagged with an “edited — will re-render” badge so you know what still needs a fresh take.

Linked lines (multi-speaker passages)

Consecutive lines can be linked so a back-and-forth exchange renders as a single conversation pass, with overlapping breath and picked-up cues — the rhythm of two people actually talking. Linked groups allow up to two distinct speakers and use the AI voices.

Previews are always free. Final chapter renders count against your balance, and re-rendering a line or passage only charges for the audio you regenerate.
