Synthesia 推出可实时对话的 AI 数字分身功能
Synthesia 把自家 Interactive Avatar 技术做成了免费小工具，录一段 2 分钟的视频就能生成会跟你实时语音对话的分身，还能切换 hype 或 roast 风格，比 HeyGen 的玩法更轻量，做内容或玩数字人的朋友可以上手试试。
Synthesia 上线了可实时语音对话的 AI 数字分身功能，用户只需录制一段约 2 分钟以内的短视频，等待分身生成后即可通过语音与它实时对话，并可用链接把分身分享给朋友。该功能免费制作，支持选择三种对话风格：standard、hype 和 roast。
技术上，这一功能基于 Synthesia 的 Interactive Avatar 技术构建，分身会对语音输入实时生成回应和口型画面，而非播放预先录制的视频。这让它从以往固定的演示视频工具转向交互式场景。
Synthesia 此前的核心产品是企业培训视频生成，此次把数字分身开放给个人免费使用，降低了实时数字人对话的门槛，与 HeyGen 等公司在交互式数字人方向形成直接竞争。
