How it works
From script to AI narration, inside the video.
Generate the voiceover, check it against the storyboard, then keep shaping the rest of the video around the same script and voice choice.
Paste or draft the script
Start with the narration you want to hear. If you only have a doc, URL, or release notes, ngram drafts the script first and then voices it.
Script ready
Pick a voice
Browse the ElevenLabs and MiniMax voices in the picker, or select a consent-based custom voice your team has saved under settings.
Voice selected
Generate the narration
ngram turns the script into voiceover, ties it to the storyboard, and aligns it with captions so spoken words and on-screen text track each other.
Voiceover generated
Edit, translate, export
Revise the script, swap the voice, regenerate a single line, translate the voiceover into another language, then export the finished video.
Ready for channels
What it can do
What the AI voice generator does inside ngram.
Generate narration as part of the video, not as a one-off audio file. The script, voice, captions, scenes, and export all stay connected.
Generate AI narration from text
Turn a product script, lesson, sales follow-up, or social caption into voiceover using ElevenLabs and MiniMax TTS, no recording session required.
Pick from a wide voice library
Choose from the voice picker that includes ElevenLabs voices and MiniMax voices, and switch the voice on any project without rewriting the script.
Use a custom team voice
Apply a consent-based custom voice from your team's voice library at /app/settings/voice when the narration should sound like a specific founder, exec, or brand presenter.
See custom voice setupKeep captions in sync
The same script drives captions and voiceover, so spoken words and burned-in captions stay aligned through every script edit.

Why ngram
How ngram compares as an AI voice generator.
The named alternatives below all publish text-to-speech and voice cloning products. The right tool depends on whether the deliverable is an audio asset or a finished video.
| Compare | ngram | ElevenLabs | Murf | Resemble AI |
|---|---|---|---|---|
| Workflow fit | Generates AI voiceover with ElevenLabs and MiniMax TTS inside the same project that holds the script, scenes, captions, and brand kit. | Publishes a dedicated AI audio platform covering text-to-speech in 70+ languages, voice cloning, a voice library, and the same voices ngram surfaces through the picker. | Markets text-to-speech with 200+ voices, 35+ languages, voice changing, AI dubbing, and Canva, Google Slides, and PowerPoint plugins. | Publishes voice cloning, text-to-speech, speech-to-speech, watermarking, and deepfake detection across audio, image, and video. |
| How ngram fits | Supports a consent-based custom voice library per team at /app/settings/voice, plus the voice picker for standard library voices. | Strong fit when the deliverable is an audio asset, a voice agent, or developer-facing TTS via API and SDK. | Strong fit for studio-style voiceover production where the team works in audio first and exports to other tools. | Strong fit when authenticity, watermarking, or deepfake defense is part of the brief. |
| Best use | Multilingual narration is part of the project, so translated voice, captions, and on-screen text export together as variants. | Pair with ngram when the same narration needs scenes, captions, branding, and a finished business video around it. | Choose ngram when the script, voice, captions, scenes, and export need to live in one video project instead of being assembled across tools. | Use ngram when the work is generating a narrated business video and the audio sits inside a script-driven storyboard. |
