Also avoid ultra-long sentences in news videos. AI avatars handle short conversational lines much better than formal broadcast paragraphs.I started using subtitles burned directly into the video because viewers forgive small sync mistakes when captions are present. Retention improved a lot on mobile viewers.For SEO, multilingual avatar news channels are becoming huge now. HeyGen’s translation and lip sync features allow creators to reuse one script across many languages without filming again. That scalability is probably the biggest AI video opportunity going into 2026.

That phonetic rewrite trick works great. Example:

“NVIDIA” → “En-vid-ee-ah”

The avatar mouth movement becomes way more accurate.

I’ve been experimenting with fully automated AI news clips using RSS feeds, GPT-generated summaries, AI voiceovers, and HeyGen avatars. Surprisingly the hardest part is not scripting, it’s keeping the avatar speech timing natural. News narration often contains difficult names and abbreviations which can break lip sync instantly. I now manually rewrite complex words phonetically before generating speech.
