🧠 What Is a Speaking Prompt in Veo 3?

A prompt is your script and scene direction rolled into one. In Veo 3, prompts are how you tell the AI:

• Who is speaking

• What they say

• How they say it

• Where they are

• What emotions and tones to express

Basic Format:

A young woman, cheerful and casual, stands on a balcony and says: “Hey there! Beautiful day, isn’t it?”

Key tips:

• Use colons (:) to cue exact dialogue

• Keep the sentence short—under 8 seconds of speech

• Match emotion + voice + setting for natural tone

🎬 Pro Prompting Techniques for Better Speaking Videos

1. Paint the Scene Like a Director

Describe not just who’s talking, but how the scene looks and feels. Add:

• Camera movement (e.g., slow zoom, shaky handheld)

• Visual tone (e.g., “moody lighting,” “sunset haze”)

• Background (e.g., forest, café, rooftop)

• Action (e.g., “she looks down, then speaks”)

This gives your prompt cinematic realism.

2. Keep Speech Short and Natural

Long lines create speed glitches or robotic tone.

Bad:

He says: “Welcome to the company. I’m glad to see you’re here. This place means a lot to all of us, especially the team.”

Better:

He says: “Welcome. We’re glad you’re here.”

---

3. Be Consistent Across Scenes

If you use the same character in multiple videos, repeat the same description every time.

Good:

Sarah, a woman in her late 30s with short red hair and a denim jacket, walks into frame and says…

Reuse this for continuity in a video series.

---

4. Emotion + Gesture = Believability

Don’t just describe the words—describe the feeling.

Example:

A teenage boy clenches his fists, eyes tearing up. He stammers: “I didn’t mean to hurt anyone…”

This adds emotional dynamics and makes the speech feel human.

---

5. Control Sound and Subtitles

Tips:

• Always use : before direct speech

• Add “no subtitles” in your prompt if captions ruin visuals

• Include ambient sound instructions:

Example:

A woman shouts over crowd noise and music: “Can anyone hear me?” (no subtitles)
