Add professional AI narration to PowerPoint slides and explainer videos using Murf Studio.
Log into Murf and click 'Create Project'. The Studio interface shows a timeline where you'll add audio blocks per slide.
Murf offers 120+ voices across 20+ languages. For presentations, filter by 'Professional' or 'Confident'. Preview the top 3 and pick based on your audience.
For each slide, add a text block with the narration script. Murf assigns timing automatically based on word count — 130–150 words per minute is typical.
Fine-tune the speaking speed per block. Business content sounds best at 90–95% speed — slightly slower than natural speech for clarity.
Select a word or phrase and click 'Emphasis' to add stress. Use this for product names, statistics, or calls to action.
Export as MP3. In PowerPoint, insert the audio per slide and set it to play automatically on slide entry. Or use Murf's direct PowerPoint add-in for automated sync.
