FLUX 3 Audio and Dialogue

Name each layer separately: speech, voiceover, ambience, effects, music, or deliberate silence. One blurred description gives up control of all of them; every sound needs a physical source or narrative role.

Speech. Quote the exact line, name the visible speaker (or label the line voiceover/narration so it is not searching for a mouth to belong to), and add no on-screen text, no subtitles when text is unwanted:

A weather presenter on camera in front of a stylized storm map, speaking directly to
the lens: "Storm season is here, and this time, we're ready." Confident delivery,
clean studio lighting. No on-screen text, no subtitles.

Voice anchors: age range, accent when relevant, register, energy, recording distance. Reusing the same direction preserves a kind of voice, not the same performer across generations.

Speakability. Write for the clip's real duration: short sentences, one thought per line, room before and after the payoff; spell unusual names phonetically; shorten the line before speeding the delivery. A line that cannot finish comfortably needs a shorter script or a longer clip.

Effects are causal, not a detached list:

As the cup hits the tile, it cracks with one sharp ceramic snap.

Mix. Say what leads and what stays under it. Keep background voices out when one line matters:

Her line is foreground and fully intelligible. Café chatter and espresso hiss remain
low and diffuse. A restrained piano pulse enters beneath the final words without
masking them.

Silence and post. Set generate_audio: false for a deliberately silent source clip. Reserve for deterministic post: final loudness, EQ, ducking, and fades; guaranteed wording or speaker identity; frame-accurate sync; subtitles and captions; continuity across separately generated clips.

When a take misses, change one dimension at a time: speaker ownership, line length, delivery anchors, competing layers, action-to-effect causality, or generation versus post.
