About a month ago I experimented with HeyGen to create an introduction to an AI for Academics course I created. Yesterday I tested the translation feature in HeyGen by converting a lecture introduction from my English transcript to Mandarin, and I’m told by the Chinese-speaking audience that it was “perfect”.
I can’t confirm the accuracy of the translation, but I’m blown away by the quality of the lip-syncing, facial expressions, and body movements of the avatar.
