AI Voice Cloning
Clone any voice with AI accuracy to create natural, personalised voiceovers that match your tone and style on any platform.
High-fidelity neural AI voice cloning
HeyGen uses advanced neural networks to analyse pitch, rhythm, accent, and speech patterns. This allows AI voice cloning to generate smooth, natural speech that works for marketing videos, training programmes, product demos, and internal communications.
Text-to-video voice generation
AI voice cloning is fully integrated into HeyGen’s text to video editor. You write or paste your script, and the platform generates the AI voice, applies lip sync, and aligns visuals automatically without manual audio editing.
Multilingual AI voice cloning support
HeyGen allows the same AI voice clone to speak multiple languages. This makes it easy to localise video content whilst keeping a consistent voice across regions, departments, and audiences.
Quick edits and reusable voice models
Once a voice is cloned, it can be reused across unlimited videos. Update text, change pacing, or adjust emphasis and re-render instantly. No re-recording is needed when content changes.
Marketing and brand videos
Traditional voiceovers require repeated recording sessions and voice talent co-ordination. With AI voice cloning, marketers write scripts and generate consistent, on-brand narration across campaigns, ads, and explainers using text-to-video workflows.
Training and onboarding content
Product demos and walk-throughs
Product updates often require new narration. With AI voice cloning, teams update scripts and regenerate demos instantly, keeping the tone of voice consistent whilst visuals and features evolve.
Social and short-form video
Internal communications
Leadership messages often lose impact when they are text only. Turn written updates into engaging videos using a cloned executive voice, helping teams communicate clearly and consistently across locations.
Multilingual customer education
Support and education teams can generate localised video guides in multiple languages using one cloned voice. This reduces production cost whilst improving clarity and trust for global audiences.
How to use an AI voice cloning tool
Create voice-powered videos through a straightforward four-step workflow that replaces recording, editing, and re-shooting.
Upload or record a voice sample
Provide a short, clean recording of the voice you want to clone. HeyGen analyses tone, pacing, and vocal characteristics to build a personalised voice model.
Generate your voice model
HeyGen processes the sample and creates a reusable AI voice clone. This voice is now available across your video projects and scripts.
Write or paste your script
Type your text directly into HeyGen’s editor. Adjust wording, emphasis, or structure whilst the system prepares narration, lip sync, and visuals automatically.
Render and update at any time
Generate the final video and export it when ready. Need changes later? Edit the text and re-render without recording again.
