An AI voice generator for video turns your script into natural-sounding narration you can drop into any edit. Instead of booking a voice actor or recording yourself, you use text to speech to get realistic AI voices that match the tone of your content—explainers, YouTube videos, product demos, or short-form. Here’s how to use text to speech for video in 2026.

Why use AI voice for video?

Video needs clear, consistent voiceover that fits the pace and mood of the edit. A free AI voice generator or voice over maker gives you lifelike speech at scale: pick a voice, set tone with Director Studio (e.g. “calm and instructional” or “energetic and confident”), and export MP3/WAV to sync in your editor—or export MP4 directly for computer-generated voice over with a single asset. No mic, no studio.

Export AI voice for video: MP4, MP3, WAV
Export voiceover as MP4 video or MP3/WAV for your editor.

Workflow: script to video voiceover

1. Script — Write or paste your narration; keep sentences clear and concise. 2. Voice — Choose from 200+ AI voices; use Director Studio to describe tone so the text to speech matches your video (e.g. “warm and clear for an explainer”). 3. Generate — Create the voiceover in the app. 4. Export — Download MP3 or WAV to sync in Premiere, DaVinci, or CapCut; or export MP4 (480p–1080p) for a ready-made text to speech for video clip. See export for TikTok, Reels, YouTube Shorts for short-form presets.

Tips for best results

  • Match voice tone to content (instructional vs promotional)
  • Use Director Studio to fine-tune (“confident and clear”, “friendly and casual”)
  • Export at the resolution you need (e.g. 1080p for YouTube, 9:16 for Reels)
  • Keep sentences short for better pacing when editing
