How to script a voiceover for a product demo video  

Before generating a voiceover with AI, it’s important to plan a clear and engaging script to easily communicate product features, values, and benefits. Here are some key steps for writing meaningful scripts for product demo voiceovers. 

1. Identify the target audience and their pain points, so you use language that they will understand and resonate with.   

2. Determine the tutorial's goal and which problems the product solves to keep the script focused.    

3. Identify the product's key features and benefits the tutorial will showcase to make the voiceover relevant to the video visuals.   

4. Make sure the script matches the intended social media platform, such as a casual tone for TikTok or a formal style for in-depth corporate explainer videos on YouTube.  

5. Add call-to-actions like website links, buttons, social media handles, or discount codes towards the end naturally so viewers don't get distracted from the demo.
