HeyGenがElevenLabsを活用してAI動画にリアルな声を提供する方法

HeyGen lets anyone create AI-powered videos — fast. Users can choose an avatar, write a script, and generate a video in minutes. But even the most realistic visuals fall short if the voice doesn’t feel human.

That’s where ElevenLabs comes in.

By integrating our voice AI into their platform, HeyGen users can pair photorealistic avatars with natural, expressive speech. The result is video content that feels engaging and believable — without recording a single line of dialogue.

Inside HeyGen, creators can connect their ElevenLabs account directly. Once linked, they can choose from a wide range of multilingual voices, customize tone and pace, and generate speech that fits the style and audience of each video.

The integration works at scale — making it possible to create thousands of videos with consistent, high-quality voiceover in any language. For enterprise teams, this opens up fast, cost-effective ways to localize content, train staff, or explain complex ideas through dynamic video.

But the value isn’t just in speed or automation. It’s an impact.

Video content is only effective if people watch it. Viewers tune out when voice quality doesn’t match visual quality. ElevenLabs helps solve that — offering nuanced, lifelike speech that keeps audiences engaged.

HeyGen’s approach shows how voice AI can be a core asset in video workflows. It’s not an add-on — it’s a multiplier. By combining ElevenLabs with avatar-led video, companies can scale communication without scaling headcount or studio time.

Use cases already span onboarding, training, marketing, and customer support. With voice and video generated on demand, teams can respond to changing needs instantly — with zero compromise on quality.

This is the new standard. Text-to-video powered by voice that actually sounds human.

And for enterprises looking to speak directly to customers, partners, or employees — at scale, in any language — ElevenLabs and HeyGen deliver a solution that’s fast, flexible, and remarkably real.

If you're building with video, but need it to talk — we’re ready when you are.
