Tips to Optimize Reels with AI Voice

• Use emotion to open. First line should feel something: surprise, nostalgia, challenge.

• Pair voice with captions. Voice catches attention, captions increase retention.

• Localize. Generate versions in multiple languages using the same narrator’s variant.

• Batch generate. Write 5 scripts, generate 5 voiceovers, and build a weekly content queue.

• Build voice consistency. Use the same narrator across your Reels to build brand recall.
