ElevenLabs vs Synthesia: AI voice and audio or AI avatar video
ElevenLabs and Synthesia are both leading AI media tools, but one starts from sound and the other from the presenter on screen. ElevenLabs is a voice platform: lifelike text to speech in 70+ languages, voice cloning, dubbing, a large voice library, music and sound effects generation, speech to text, and an API used by developers to build all of this into their own products.
Synthesia makes videos with AI avatars and voiceovers in 140+ languages. You pick from hundreds of stock avatars or create your own, turn documents, slides or links into videos, translate them in a click with lip-synced dubbing, and keep output on brand with Brand Kits. It is aimed squarely at business video such as training, compliance and sales enablement.

Our verdict
ElevenLabs leads for most readers because voice is the part of AI media that most projects need, and it covers voice more broadly than anything else in this category. Narration, podcasts, audiobooks, ads, game characters, dubbing existing videos and voice features in an app all start here, and the API means it scales from a single creator to a product used by millions.
Synthesia is the better pick if what you need is a finished video with a person on screen, produced without cameras or presenters. Learning and development teams, internal communications and sales enablement get a complete workflow, from slides to avatar video to translated versions, plus enterprise controls and certifications such as SOC 2 Type II, ISO 27001 and EU data residency.
If you use either to clone a real person's voice or likeness, get that person's written consent first.
