This keyword usually means you want a short, recognizable reaction line that lands on a reveal. The best results come from prompting the delivery style, mic distance, and how the tail ends. Use these quick checks to choose a stock clip or generate a custom take that matches your scene timing and context.
Pick the delivery and emotion
Decide what the audience should feel in the moment: curiosity, disbelief, disgust, excitement, or deadpan comedy. The same words can read totally differently based on inflection and pace.
- Use emotion words: skeptical, amazed, annoyed, delighted, cautious
- Specify pace: quick blurt, slow drawl, or a pause before speaking
- Call out intensity: subtle under-breath vs big over-the-top reaction
Control space and perspective
The perceived distance matters more than you think. A close-mic take cuts through a mix, while a distant call sounds like it belongs to the room on screen.
- Choose perspective: close-mic, medium distance, or far hallway
- Mention room tone: quiet bedroom, office, tiled corridor
- Set reflections: dry and tight, or light reverb with a longer tail
Make it cut-friendly
Reaction lines often need a clean transient and an ending that does not collide with the next line or music hit. Prompt the tail behavior so you do less trimming later.
- Ask for a tight cutoff when you need a hard edit point
- Request a natural decay if it should feel spoken in a real space
- Keep loudness consistent if you will use it as a repeatable soundboard button
Avoid common prompt pitfalls
Small wording changes can prevent unusable takes. If a result sounds messy, update the prompt with constraints instead of regenerating the same vague request.
- Avoid conflicting notes like "whisper" plus "shout" in one take
- If it sounds harsh, ask for reduced sibilance and smoother highs
- If the room feels wrong, explicitly ask for dry room or stronger reflections
